This article explores how global shifts in capital, production, the labor market, and its segmentation relate to mobility strategies and community ties in a specific local context. Mobility strategies or the refusal to be mobile are, at times, used in order to maintain households in communities that have seen their labor market constrict. Decisions about mobility are not purely about economic rationality. In the mobility strategies employed by former pulp and paper workers from Miramichi, New Brunswick, Canada, resistance to mobility is due to community and familial ties to place. Such local commitments may take precedence over, but are clearly impacted by, the ever-shifting tides of global capital. [ABSTRACT FROM AUTHOR]

An effective and just industrial transition is necessary both to mitigate climate change and protect jobs, and as a precursor to enable other sectors to decarbonise. Activity is at an early stage and examples of successful sector-wide interventions to decarbonise industry do not yet exist. Governments of industrialised countries are beginning to develop policy and provide funding to support deployment of carbon capture and low-carbon hydrogen infrastructures into high-emitting industrial clusters, but options for sites outside of clusters, denoted here as 'dispersed sites', are also required. This paper takes a mixed methods approach to provide the first analysis of the issues facing dispersed industrial sites on their route to decarbonisation and to suggest solutions to the challenges they face. Using the UK as a case study, it first characterises dispersed sites in terms of location, emissions released, sectors involved, and size of companies affected. It then shows how these features mean that simply expanding the geographical scope of the present UK decarbonisation strategy, which focuses on the provision of carbon capture and low-carbon hydrogen, would face a number of challenges and so will need to be broadened to include a wider range of abatement options and other considerations to meet the needs of dispersed sites. While the solutions for each place will be different, these are likely to include some combination of the expansion of shared infrastructure, the development of local zero-carbon hubs, research into a wider range of novel abatement technologies and facilitating local participation in energy planning. The paper concludes with a discussion of remaining knowledge gaps before outlining how its findings might apply to industrial decarbonisation strategies in other countries. [ABSTRACT FROM AUTHOR]

Changing institutions is an integral part of an academic life. Yet little is known about the mobility patterns of scientists at an institutional level and how these career choices affect scientific outcomes. Here, we examine over 420,000 papers, to track the affiliation information of individual scientists, allowing us to reconstruct their career trajectories over decades. We find that career movements are not only temporally and spatially localized, but also characterized by a high degree of stratification in institutional ranking. When cross-group movement occurs, we find that while going from elite to lower-rank institutions on average associates with modest decrease in scientific performance, transitioning into elite institutions does not result in subsequent performance gain. These results offer empirical evidence on institutional level career choices and movements and have potential implications for science policy. [ABSTRACT FROM AUTHOR]

Covid-19 and the measures taken to contain it have led to unprecedented constraints on work and leisure activities, across the world. This paper uses nationally representative surveys to document how people of different ages and incomes have been affected in the early phase of the pandemic. The data was collected in six countries (China, South Korea, Japan, Italy, UK, and US) in the third week of April 2020. First, we document changes in job circumstances and social activities. Second, we document self-reported negative and positive consequences of the crisis on well-being. We find that young people have experienced more drastic changes to their life and have been most affected economically and psychologically. There is less of a systematic pattern across income groups. While lower income groups have been more affected economically, higher income groups have experienced more changes in their social life and spending. A large fraction of people of low and high income groups report negative effects on well-being. [ABSTRACT FROM AUTHOR]

Current developments in fields such as quantum physics, fine arts, robotics, cognitive sciences or defense and security indicate the emergence of creative systems capable of producing new and innovative solutions through combinations of machine learning algorithms. These systems, called machine invention systems, challenge the established invention paradigm in promising the automation of – at least parts of – the innovation process. This paper's main contribution is twofold. Based on the identified state-of-the-art examples in the above mentioned fields, key components for machine invention systems and their relations are identified, creating a conceptual model as well as proposing a working definition for machine invention systems. The differences and delimitations to other concepts in the field of machine learning and artificial intelligence, such as machine discovery systems are discussed as well. Furthermore, the paper briefly addresses the social and societal implications and limitations that come with the adoption of the technology. Because of their revolutionizing potential, there are widespread implications to consider from ethical and moral implications to policymaking and societal changes, like changes in the job structure. The discussion part approaches some of these implications, as well as solutions to some of the proposed challenges. The paper concludes by discussing some of the systemic benefits that can be accessed through machine invention. [ABSTRACT FROM AUTHOR]

We consider the classical machine scheduling, where n jobs need to be scheduled on m machines, and where job j scheduled on machine i contributes p ij ∈ R to the load of machine i, with the goal of minimizing the makespan, i.e., the maximum load of any machine in the schedule. We study the inefficiency of schedules that are obtained when jobs arrive sequentially one by one, and the jobs choose the machine on which they will be scheduled, aiming at being scheduled on a machine with a small load. We measure the inefficiency of a schedule as the ratio of the makespan obtained in the worst-case equilibrium schedule, and of the optimum makespan. This ratio is known as the sequential price of anarchy (SPoA). We also introduce two alternative inefficiency measures, which allow for a favorable choice of the order in which the jobs make their decisions. As our first result, we disprove the conjecture of Hassin and Yovel (Oper Res Lett 43(5):530–533, 2015) claiming that the sequential price of anarchy for m = 2 machines is at most 3. We show that the sequential price of anarchy grows at least linearly with the number n of players, assuming arbitrary tie-breaking rules. That is, we show SPoA ∈ Ω (n) . At the end of the paper, we show that if an authority can change the order of the jobs adaptively to the decisions made by the jobs so far (but cannot influence the decisions of the jobs), then there exists an adaptive ordering in which the jobs end up in an optimum schedule.

This paper contributes to the scarce literature on the topic of horizontal education-job mismatch in the labor market for graduates of universities. Field-of-study mismatch or horizontal mismatch occurs when university graduates, trained in a particular field, work in another field at their formal qualification level. The data used in the analysis come from the first nationally representative survey of labor insertion of recent university graduates in Spain. By estimating a multinomial logistic regression, we are able to identify the match status 4 years after graduation based on self-assessments. We find a higher likelihood of horizontal mismatch among graduates of Chemistry, Mathematics, Physics, Pharmacy, and Languages and Literature. Only graduates in Medicine increase the probability of being adequately matched in their jobs. It may be hypothesized that horizontal mismatch is more likely among those graduates in degree fields that provide more general skills and less likely among those from degree fields providing more occupation-specific skills. Other degrees such as Business Studies, and Management and Economics Studies increase the probability of being vertically mismatched (over-educated). Vertical mismatch preserves at least some of the specific human capital gained through formal educational qualifications. However, some workers with degrees in Labor Relations and Social Work are in non-graduate positions and study areas unrelated to their studies. The paper also shows that graduates in the fields of health sciences and engineering/architecture increase the probability of achieving an education-job match after external job mobility.

This paper presents a model considering intergenerational occupational mobility as the joint outcome of three main determinants: income incentives, equality of opportunity and changes in the composition of occupations. The model, rationalising the use of transition matrices to measure occupational mobility, allows for identifying asymmetric mobility patterns and constructing a specific mobility index for each determinant. The empirical application of our model to Italy suggests that intergenerational mobility increased from the cohort of children born in the period 1940-1951 to the one born in the period 1952-1965, then to remain at the same level for the cohort of children born in the period 1966-1977. This steady mobility, however, hides i) lower structural mobility, caused by a declining trend in the composition of occupations in favour of upper-middle classes; ii) less upward mobility for those whose fathers were in the lower class; and iii) higher downward mobility from upper-middle classes, both caused by a decrease in the income incentives. Equality of opportunity is low and constant for those born after 1951. [ABSTRACT FROM AUTHOR]

International scientific mobility and research careers are two concepts that are intimately related. Yet, it has been very difficult for scholarship to pinpoint exactly how international mobility impacts on research careers. This paper contributes to this question by investigating links between international mobility, research career stage progression and job changes. It does so using a large-scale survey (MORE) which targets researchers based in European universities. The results establish that the profile of international mobility varies by academic research career stage. They also show that for researchers in the established mid-career phase who are working internationally, there are career advancement benefits associated with return mobility to their home country. However, these benefits may reduce if the timing of return is too delayed. The paper concludes by discussing the implications of these results for researcher mobility policy in the context of the European Higher Education Area and the European Research Area.

Through a case study of a girl student, this paper attempts to draw linkages between science classroom, gender and the larger discourse on the economy and job market. The ideal science student is constructed through classroom interactions, and a particular ideal is fostered which is highlighted in this paper. This paper sets itself to locate the micro-processes such as the classroom interactions, pedagogy and textbooks in the larger macro-context of economy, social mobility and jobs. It draws from the critiques of meritocracy and neoliberal ideology to present the arguments. Through an ethnographic approach, the study focuses on the experiences of students in science classrooms. The school chosen is located in an urban context in India. Examples from the classroom interactions and discussions with the students reveal how certain kind of conduct is promoted in the classroom. Through the description of dreams and aspirations and notions of science and scientists of a girl student, this paper argues that the learning of science is situated in the context of globalisation and neoliberal ideology. The classrooms, pedagogy and notion of aspirations and mobility seem to foster this economic discourse. This paper points to the fact that there is a need for alternative approaches in the teaching of science. [ABSTRACT FROM AUTHOR]

As China has become the largest user of industrial robots, the need to understand how workers perceive robot-human substitution and how their perceptions influence their job behaviors is becoming increasingly crucial. This paper examined whether workers' fear of being replaced by robots (FRR) is correlated with one aspect of job behavior: turnover intention, which refers to the extent to which an individual intends to change their job within a specific time period. Using a dataset covering 1512 manufacturing workers in Guangdong province of China, we found that workers who fear losing their jobs to robots report significantly higher turnover intention. We also found that the positive effect of FRR on turnover intention increased when robots were already utilised in the workplace. This effect was also found to be increase when workers perceived that their wages did not increase with the rise in productivity due to robotisation. Based on these findings, we provide practical recommendations to organizations on effectively addressing the turnover intention arising from the FRR. [ABSTRACT FROM AUTHOR]

This paper considers the allocation of resources when people choose separately their residence and the place of work. The purpose of the paper is threefold. First, it derives necessary conditions for an efficient distribution of workers and residents. Second, besides efficient allocations market equilibria are discussed. Third, the paper also develops a spatial model with local public goods and discusses within the framework the impact of local public goods on the distribution of people and vice versa.

Purpose: Both depression and loneliness have been recognized as major public health issues, yet investigation into their role among young and middle-aged, professionally active persons is still required. The aim of the present study was to evaluate whether depression and loneliness may independently predict inefficiency at work among professionally active adults. Methods: This is a cross-sectional study on a representative, nationwide sample. 1795 questionnaires were gathered from among professionally active adults from Poland from 1 to 31 July 2018 with a direct pen-and-paper interview. The sample was chosen by means of the stratified random method. The survey included a Patient Health Questionnaire (PHQ-9) to measure depression and questions, devised by the authors, relating to loneliness and inefficiency at work. Regression models were constructed with depression and loneliness as predictors of inefficiency at work, unadjusted and adjusted for selected sociodemographic, health- and work-related factors. Results: In the unadjusted models, both depression and loneliness were independently associated with an increase of work inefficiency and absence from work, with effect sizes being higher for loneliness than for depression. After accounting for the control variables (i.e., sociodemographic, work- and health-related factors), the PHQ-9 score, but not the loneliness score, was associated with an increased probability of frequent thoughts about changing or leaving a job. Conclusion: Depression and loneliness independently predicted occupational functioning and differentially affect its various aspects. Counteracting depression and loneliness among employees should be regarded as a public health priority. [ABSTRACT FROM AUTHOR]

The Routine-Biased Technological Change (RBTC) has been regarded as a relatively novel technology-based explanation of social changes affecting job and wage polarization. In this paper, we investigate wage inequality between routine and non-routine workers along the wage distribution in Italy. Thanks to unique survey data, we can estimate the wage differential using both the actual and the perceived level of routine intensity of jobs to classify workers. We adopt semi-parametric decomposition techniques to quantify the importance of worker characteristics in explaining the gaps. We also employ non-parametric techniques to account for self-selection bias. We find evidence of a significant U-shaped pattern in the wage gap, according to both definitions, with non-routine workers always earning significantly more than routine workers. Results show that worker characteristics fully explain the gap in the case of perceived routine, while they account for no more than 50% of the gap across the distribution in the case of actual routine. Thus, the results highlight the importance of taking into account workers' perceptions to reduce the set of omitted vaiables when analyzing determinants of wage inequality. [ABSTRACT FROM AUTHOR]

Since the dawn of programming, several developments in programming language design and programming methodology have been hailed as the end of the profession of programmer; they have all proven to be exaggerated rumors, to echo the words attributed to Mark Twain. In this short paper, we ponder the question of whether the emergence of large language models finally realizes these prophecies? Also, we discuss why even if this prophecy is finally realized, it does not change the job of the researcher in programming. [ABSTRACT FROM AUTHOR]

This paper studies the economic effect of immigration on native working conditions, focusing on the impact of the inflow of immigrant labour on occupational mobility among native workers. Basing on a gender-segmented labour market, we propose an extension of the model presented by Peri and Sparber American Economic Journal: Applied Economics, 1(3), 135-169, (2009). The model controls for gender and time in order to check for potential differences in immigration effects associated with gender or immigrant length of residence. This research reveals the existence of such differences, by showing that female immigrant inflow has a greater positive short-term impact on occupational mobility among female unskilled native workers. In addition, the long-term study discloses a slight occupational assimilation of male immigrants towards employment patterns of male native workers and a permanent confinement of female immigrants in a few 'niche jobs'.

This paper investigates the association between total factor productivity growth and the R&D expenditures of Swedish manufacturing firms in the presence of domestic- and international R&D spillovers. The paper assumes that the principal channel of transmission of new technology is through I/O relations. Econometric evidence suggests that international as well as domestic inter-industry R&D spillovers are important determinants of firms’ productivity growth in the long run. The R&D spillovers generated within the industry and following I/O links seem to be of minor importance in explaining productivity growth. It seems likely that within-industry productivity spillovers follow other channels than I/O flows, such as horizontal spillovers through copying of new products and processes, or labour turnover. The use of a convergence parameter is one way to check for such within-industry technology flows. Our results indicate that a catch-up process exists by which the non-frontier firms in the Swedish manufacturing sector absorb knowledge spillovers from the leading firms in the industry. Finally, a firm’s own R&D efforts are found to be more or less positively correlated with the TFP growth, maybe the contribution from R&D efforts in some sense are underestimated.

This paper considers single-machine scheduling problems in which a given solution, i.e., an ordered set of jobs, has to be improved as much as possible by re-sequencing the jobs. The need for rescheduling may arise in different contexts, e.g., due to changes in the job data or because of the local objective in a stage of a supply chain that is not aligned with the given sequence. A common production setting entails the movement of jobs (or parts) on a conveyor. This is reflected in our model by facilitating the re-sequencing of jobs via a buffer of limited capacity accessible by a LIFO policy. We consider the classical objective functions of total weighted completion time, maximum lateness and (weighted) number of late jobs and study their complexity. For three of these problems, we present strictly polynomial-time dynamic programming algorithms, while for the case of minimizing the weighted number of late jobs NP-hardness is proven and a pseudo-polynomial algorithm is given.

This paper presents new evidence on the evolution of job polarisation in Spain between 1994 and 2014. After showing the U-shaped relationship between employment share growth and job’s percentile in the wage distribution, I use the task approach to investigate the main determinants behind job polarisation. Using the European Working Condition Survey I analyse in detail the task content of the jobs which display the most significant employment changes. I show that changes in employment shares are negatively related to the initial level of routine. I then explore the impact of computerisation on routine task inputs and I find that the routine measure is negatively related to computerisation. Finally, by using information on past jobs, I provide evidence on the displacement of middle-paid workers. Results suggest that they did not predominantly relocate their labour supply to bottom-paid occupations: while non-graduate middle workers move towards bottom occupations, graduate middle employees shift towards top occupations. This fact suggests that supply-side changes are important factors in explaining the expansion at the lower and upper tail of the employment distribution. [ABSTRACT FROM AUTHOR]

This paper empirically examines the search behavior of currently employed workers to understand changes in on-the-job search across different types of employed individuals and varying labor market conditions. Using data from the American Time Use Survey, we estimate the responsiveness of workers with varying levels of productivity and job-match quality to regional labor market conditions. We find that those workers who are less-productive, mismatched in their current position, and high-productivity, mismatched workers are more likely to engage in search than other workers. These results have implications for models built on job mismatch, as well as for models seeking to explain increasing inequality and wage dispersion. [ABSTRACT FROM AUTHOR]

This paper analyses the situation when employees fail to adapt to overall job dissatisfaction. By combining the existing knowledge in economics on job lock and in psychology on employees' feeling of being 'stuck' at work, the paper explains why some employees fail to adapt when dissatisfied with their job. Thus, the paper aims to expand our understanding of why some employees are job locked or are 'stuck' at their work even though dissatisfied. Using the British household panel survey, the possibility of falling in a job-lock state is analyzed to outline a set of factors that explain why employees differ in the way they adjust to job dissatisfaction. We divide these factors into socio-demographic features, personality attributes, type of occupation, employment conditions, type of sector, and work-related contextual features. Based on results of probit regression analysis, we provide evidence that all these group of factors can jointly predict the state of job dissatisfaction, the absence of job turnover and job lock (being 'stuck' at job). Moreover, our results suggest that the adaptation to job dissatisfaction could be better understood if personality attributes (such as self-esteem) are included in the analysis. Thus, this study expands our understanding of how and why employees might feel 'stuck' at work and fall in a state of job lock. [ABSTRACT FROM AUTHOR]

The question of complementarity or substitutability of FDI and international labour mobility has not yet been answered. The substitutability assumption does not take into consideration the technological spillover of FDI in the host countries. Moreover, migration flows reveal cultural characteristics and labour force properties of their native country which may stimulate bilateral business networks, strengthening the complementarity assumption between capital and labour flows. In this paper we build a continuous time dynamic model where these offsetting forces are at work. We analyze whether, and to what extent, the increase in labour mobility might affect FDI outflows. A numerical simulation is performed showing that a higher income growth rate corresponds to a higher labour mobility. Some policy implications and further research direction are suggested.

Aim of the paper is to provide a new class of mobility indices that takes into account the inter-temporal status movements over more than two periods of time. The index is obtained in two steps. First, an individual inter-temporal individual mobility index is provided, which allows also for analysis of upward and downward mobility. Since memory plays an important role when an individual makes comparisons with his past, a discount factor has been introduced. Secondly, individual mobility indicators are aggregated over all the population, in order to obtain an index that allows for comparisons among different societies. The empirical application analyzes the mobility of the occupational status in the Italian labour market within an inter-temporal framework, using the Italian Compulsory Communications system data.

Racial/ethnic minorities, especially people racialized as Black and Latino, face disadvantages at work. Our research reaffirms and adds insight into this disadvantage, showing that compared to people racialized as White, racial minorities experience limited internal mobility and as a result greater geographic instability. Using data from a longitudinal study of the careers of NCAA Division I assistant and associate head basketball coaches, we show first that these coaches are more likely to experience internal job mobility if they are White. We also consider what this means for race differences in geographic mobility, establishing that coaches who are White move shorter distances following a job change on average because they are more likely to experience internal occupational mobility. These findings highlight yet another way restricted work opportunity culminates to disadvantage racial minorities in this profession. [ABSTRACT FROM AUTHOR]

In this paper, we analyzed the association among trends in COVID-19 cases, climate, air quality, and mobility changes during the first and second waves of the pandemic in five major metropolitan counties in the United States: Maricopa in Arizona, Cook in Illinois, Los Angeles in California, Suffolk in Massachusetts, and New York County in New York. These areas represent a range of climate conditions, geographies, economies, and state-mandated social distancing restrictions. In the first wave of the pandemic, cases were correlated with humidity in Maricopa, and temperature in Maricopa and Los Angeles. In Suffolk and New York, cases were correlated with mobility changes in recreation, grocery, parks, and transit stations. Neither cases nor death counts were strongly correlated with air quality. Periodic fluctuations in mobility were observed for residential areas during weekends, resulting in stronger correlation coefficients when only weekday datasets were included in the analysis. We also analyzed case-mobility correlations when mobility days were lagged, and found that the strongest correlation in the first wave occurred between 12 and 14 lag days (optimal at 13 days). There was stronger but greater variability in correlation coefficients across metropolitan areas in the first pandemic wave than in the second wave, notably in recreation areas and parks. In the second wave, there was less variability in correlations over lagged time and geographic locations. Overall, we did not find conclusive evidence to support associations between lower cases and climate in all areas. Furthermore, the differences in cases-mobility correlation trends during the two pandemic waves are indicative of the effects of travel restrictions in the early phase of the pandemic and gradual return to travel routines in the later phase. This study highlights the utility of mobility data in understanding the dynamics of disease transmission. It also emphasizes the criticality of timeline and local context in interpreting transmission trends. Mobility data can capture community response to local travel restrictions at different phases of their implementation and provide insights on how these responses evolve over time alongside disease trends.

The objective of this paper is to analyse occupational mobility among immigrants in Spain in two distinct stages: (1) comparing the immigrants' first job in Spain with their profession in the country of origin and (2) comparing their current occupational status with the occupational status of the first job they held in Spain. We focus on immigrants who arrived in Spain during the 'immigration boom' that took place between 1997 and 2007, using data from the 2007 National Survey on Immigration. For our analysis, we use occupational mobility tables and multi-variable models with occupational mobility as a dependent variable. Our results show that we can better understand the initial access of migrants to the Spanish labour market from the perspective of labour market segregation: for each gender, a particular sector/occupational level (construction and cleaning, respectively) played such a dominant role that it determined almost entirely the observed mobility pattern. We find some (upward) mobility opportunities after such initial strong segregation, which increased with length of residence; however, our results suggest that, even in this case, it is mostly limited to men and associated with the construction boom that finished abruptly in 2007.

This paper analyzes self-employment entry among Swedish-born male wage-earners. Is it the best and the brightest or the least successful that become self-employed? The residual from an income regression is used as an indicator of who belongs to which group. We find that both wage-earners who receive a lower income than predicted, i.e. have a negative residual, and those who receive a higher income than predicted, i.e. have a positive residual, are more likely to become self-employed than those who receive an income close to the predicted one. However, splitting self-employment into different types depending on corporate form and number of employees, we find that the self-employed are drawn from both tails of the residual distribution only if it is a matter of unincorporated firms. Wage-earners who become self-employed and start an incorporated firm are only drawn from the top of the residual distribution. Using self-employment income and turnover as measures of self-employment performance, we find a positive linear relationship between the income residual and performance. [ABSTRACT FROM AUTHOR]

Shrimp trawling represents an important fishing métier in South India, generating high levels of employment and economic value. It is also a contested métier, ostensibly contributing to environmental degradation and social inequality. This paper investigates the job satisfaction of crew members (captains and workers) on board the shrimp trawlers of Chennai (former Madras). Research took place in 2007 and 2008 (N = 137). Results suggest a general satisfaction with being in the fishery. However, a little over three-fifths of fishers said they would be willing to change fishing métier and about one-half said they would leave the occupation. About one-half also said they would not advise a young person to enter the occupation. The tendency to move away from the fishery is argued to reflect a growing pessimism about the future of the shrimp trawl fisheries, but also an increasing awareness of other economic opportunities.

The paper studies whether temporary jobs in the form of fixed-term replacement contracts reduce the risk of future unemployment among job-seekers. Usingmatching on detailed information on labour market history and personal characteristics we find positive average effects of having a replacement contract. Our second focus is on whether the duration of the contract matters. We use data on replacement contracts with information on the ex ante duration of the contract which is determined by the individual on leave and find no significant effect on the subsequent unemployment risk of the replacement worker. However, the longer the replacement contract the higher is the probability of having an open ended contract at the same site 2-2.5 years after the start of the contract. Overall, the results suggest that replacement contracts may reduce the risk of future unemployment, but that longer contracts only improve the position within the workplace and not necessarily on the labour market in general.

This paper analyses the relationship between earnings mobility, job mobility and changes in the contractual arrangement in Spain using a sample of Spanish workers aged 16–60 years extracted from the European Community Household Panel Survey (ECHP 1995–2001). Overall, earnings mobility remains mostly unchanged over time, although clear differences, both in terms of levels and trends, can be perceived among different types of workers. Results show that, in general, job mobility contributes to increase earnings mobility. Switching into permanent contract are associated with the highest probability of upgrading among those workers who remain with the same employer. In contrast, the highest risk of downgrading among stayers appears when changing from permanent to temporary. An analysis on low pay/no low pay transitions reveals that job mobility always increases the probability of moving from low pay to better-paid jobs among females. For males, in contrast, this occurs only when they were initially employed on a temporary basis. Furthermore, for females it is found that either switching into permanent contract while staying with the same employer, or changing employer while being employed on a permanent basis yield a higher chance of upgrading than staying with the same employer with a permanent contract.

Occupational employment projections are one of the primary products produced by state labor market information agencies to assist with state and regional job training and worker assistance programs. In theory, the information from occupational employment forecasts should improve both interregional and intertemporal labor market efficiency through better matching between training efforts and job openings. Until recently, the projections methodology was predominantly a demand-requirements approach that failed to incorporate important labor supply effects and interstate/interregional dependencies. Recent research has focused on improving the labor supply specification. This paper reports on one such effort to evaluate the importance of interstate occupational migration and to develop methods to incorporate migration into the existing projections methodology. Initial results indicate that the total number of estimated job openings by occupation have to be revised significantly upwards when migration is taken into account. [ABSTRACT FROM AUTHOR]

Makespan minimization on identical parallel machines is a classical scheduling problem. We consider the online scenario where a sequence of n jobs has to be scheduled non-preemptively on m machines so as to minimize the maximum completion time of any job. The best competitive ratio that can be achieved by deterministic online algorithms is in the range [1.88, 1.9201]. Currently no randomized online algorithm with a smaller competitiveness is known, for general m. In this paper we explore the power of job migration, i.e. an online scheduler is allowed to perform a limited number of job reassignments. Migration is a common technique used in theory and practice to balance load in parallel processing environments. As our main result we settle the performance that can be achieved by deterministic online algorithms. We develop an algorithm that is $$\alpha _m$$ -competitive, for any $$m\ge 2$$ , where $$\alpha _m$$ is the solution of a certain equation. For $$m=2$$ , $$\alpha _2 = 4/3$$ and $$\lim _{m\rightarrow \infty } \alpha _m = W_{-1}(-1/e^2)/(1+ W_{-1}(-1/e^2)) \approx 1.4659$$ . Here $$W_{-1}$$ is the lower branch of the Lambert W function. For $$m\ge 11$$ , the algorithm uses at most 7 m migration operations. For smaller m, 8 m to 10 m operations may be performed. We complement this result by a matching lower bound: No online algorithm that uses o( n) job migrations can achieve a competitive ratio smaller than $$\alpha _m$$ . We finally trade performance for migrations. We give a family of algorithms that is c-competitive, for any $$5/3\le c \le 2$$ . For $$c= 5/3$$ , the strategy uses at most 4 m job migrations. For $$c=1.75$$ , at most 2.5 m migrations are used. [ABSTRACT FROM AUTHOR]

This paper quantitatively analyzes the trade-off between job losses and the spread of COVID-19 in Japan. We derive an empirical specification from the social planner's resource constraint under the susceptible, infected, recovered, and deaths (SIRD) model and estimate how job losses and the case growth rate are related to people's mobility using the Japanese prefecture-level panel data on confirmed cases, involuntary job losses, people's mobility, and teleworkability. Our findings are summarized as follows. First, we find that a decrease in mobility driven by containment policies is associated with an increase in involuntary job separations, but the high teleworkability mitigates the negative effect of decreased mobility on job losses. Second, estimating how the case growth is related to people's mobility and past cases, we find that the case growth rate is positively related to an increase in people's mobility but negatively associated with past confirmed cases. Third, using these estimates, we provide a quantitative analysis of the trade-off between job losses and the number of confirmed cases. Taking Tokyo in July 2020 as a benchmark, we find that the cost of saving 1 job per month is 2.3 more confirmed cases per month in the short run of 1 month. When we consider a trade-off for 3 months from July to September of 2020, protecting 1 job per month requires 6.6 more confirmed cases per month. Therefore, the trade-off becomes worse substantially in the longer run of 3 months, reflecting the exponential case growth when the people's mobility is high. [ABSTRACT FROM AUTHOR]

Using the 1970 Census data, this paper examines differences by sex in patterns of intragenerational occupational mobility over a five year period (1965-1970) for two cohorts of white, U.S. men and women. The observed mobility patterns are separated into that part due to structural factors (i.e., the different distributions over occupational origins and destinations by sex) and that due to sex-related individual and group characteristics. Most of the observed differences in mobility patterns are found to be the result of occupational sex segregation. [ABSTRACT FROM AUTHOR]

This paper fits in with the literature on signaling, and it stresses the role of sequentially improved job-worker allocation. Allocation is initially done on the basis of signals but later, on the basis of true abilities, as revealed from productive performance. The model yields predictions in line with observations: upward sloping average age-earnings profiles, increasing wage dispersion within signal classes (such as schooling), increasing effect of ability on earnings, higher earnings growth for abler individuals. The model thus demonstrates that the gradual sorting-out of individuals into jobs may be very important, and it also indicates how information on individual abilities may gradually emerge.

Log-linear models afford a wide range of tests regarding specific aspects of the association between two ordinal-level variables with identical attributes. This range is considerably broadened when orthogonal contrasts are used to trace changes in these aspects over time. This paper provides descriptions and graphic illustrations of six common log-linear models' applications to mobility data on U.S. white males. The models are then expanded to examine temporal variations in aspects of the mobility regime captured by the respective models. The analysis shows a significant increase over the period of study in the odds that white males from blue collar backgrounds attain higher occupational statuses. Moreover, the findings indicate that blue collar workers are more likely to be drawn from lower status origins during years of economic prosperity, and from higher status origins at times of economic dearth.

This article discusses various research papers regarding occupational mobility. There has been a resurgence of interest in the analysis of occupational mobility tables. One of the more exciting models which has been proposed is the structural model of researcher R.M. Hauser. Two research papers acknowledging Hauser's work have sought to develop such models further. The argument of this article, however, is that the interpretative claims made for Hauser's structural model cannot be sustained, and that accordingly analyses based upon it are misleading. The argument proceeds by initially accepting the proferred interpretation and applying the model to a set of data. This application generates a conflict. Various resolutions are explored. It is argued that were there a resolution it would have to lie with the substantive interpretability of the model, but it is further argued that the model cannot support such interpretations. The article ends by discussing the source of the indeterminacy, and suggesting an analysis strategy which would retain the odds-ratio structure of the table, as the structural model also does, but would avoid fraught decompositions.

The literature on neighbourhood effects suggests that the lack of social mobility of some groups has a spatial dimension. It is thought that those living in the most deprived neighbourhoods are the least likely to achieve upward mobility because of a range of negative neighbourhood effects. Most studies investigating such effects only identify correlations between individual outcomes and their residential environment and do not take into account that selection into neighbourhoods is a non-random mechanism. This paper investigates occupational mobility between 1991 and 2001 for those who were employed in Scotland in 1991 by using unique longitudinal data from Scottish Longitudinal Study (SLS). We add to the existing literature by investigating neighbourhood effects on occupational mobility separately for social renters, private renters and home owners. We find that 'neighbourhood effects' are strongest for home owners, which is an unexpected finding. We argue that the correlation between characteristics of the residential environment and occupational mobility can at least partially be explained by selection effects: homeowners with the least resources, who are least likely to experience upward mobility, are also most likely to sort into the most deprived neighbourhoods. Social housing tenants experience less selective sorting across neighbourhoods as other than market forces are responsible for the neighbourhood sorting mechanism. [ABSTRACT FROM AUTHOR]

Third-country immigrants are over-represented among lower status workers in all EU countries and rarely achieve upward mobility. The present paper aims to analyse the migration trajectories of foreign-born women who entered the Italian labour market as domestic workers, in order to assess the role of personal and group characteristics in determining the chances of leaving this sector. The data were collected as part of a project studying the working trajectories of migrants in Italy. The survey was conducted during 2009 on 13,000 migrants aged 18 and over, living in Italy at the time of the interview and born in high emigration countries. We used a piecewise exponential model with random intercept for citizenship with time measured from the beginning of the person's first domestic work in Italy. Our results show low exit rates from the domestic sector but we identify personal and group characteristics which facilitate exit from this segment of the labour market. Employment experience, including unskilled, has a positive effect on the transition in the host country, as do education achieved in the country of origin and higher levels of tasks and duties in the last job held in the country of origin, whereas ethnic networks limit access to other occupations. The aims of the women's migration project include a strong emphasis on occupational mobility, whether they migrate for work or for family reasons. Finally, we find evidence of the existence of a 'U-shaped' pattern in occupational mobility for this particular subpopulation of workers. [ABSTRACT FROM AUTHOR]

This paper studies the contribution of different skill groups to the polarisation of the UK labour market. We show that the large increase in graduate numbers contributed to the substantial reallocation of employment from middling to top occupations which is the main feature of the polarisation process in the UK over the past three decades. The increase in the number of immigrants, on the other hand, does not account for any particular aspect of the polarisation in the UK. Changes in the skill mix of the workforce account for most of the decline in routine employment across the occupational distribution, but within-group changes account for most of the decline in routine occupations in middling occupations. In addition, there is no clear indication of polarisation within all skill groups—a fact that previous literature has cited as evidence that technology drives the decline of middling occupations. These findings differ substantially from previous evidence on the US and cast doubts on the role of technology as the main driver of polarisation in the UK. [ABSTRACT FROM AUTHOR]

This paper examines the impact of international migration on the occupational mobility of workers over the three phases of labour migration—pre-emigration, emigration and post-return—by constructing mobility matrices using the sample of return emigrants from the Kerala Migration Survey 2011. The study finds that a large proportion of emigrants from Kerala take up occupations in the service sector while abroad irrespective of their pre-emigration occupation or training. Most emigrants return, while they are still in the labour force, and the major reason for returning is adverse labour market conditions at the destination. Though around half of the return emigrants report the inclination to take up entrepreneurial activities, only about 10% are engaged in self-employment, suggesting that there is no real evidence of a rapid boost to entrepreneurship. The study finds that there is moderate mobility between the pre-emigration occupation and the occupation abroad as well as between the occupation abroad and post-return, but not between occupations in the pre-emigration–post-return phases, indicating that workers move out of their traditional occupations while abroad, but most likely return to their original occupation post-return. Work experience abroad does not cause any significant upward mobility in any occupational groups except among professionals, who move to managerial positions post-return. [ABSTRACT FROM AUTHOR]

Migration and remittance certainly influence the occupational mobility (Carletto and Kilic in J Dev Stud 47(6):846–869, 2011) by reducing liquidity constraint, leisure preference and family structure (Torrado in It does not make us lazy: evidence against the moral hazard effect of remittances, The World Bank, Washington, 2012). Diversified evidences suggest to us that the effect of remittance on occupational choice or mobility is shaped by differential social–economic background, social norms and local market requirement. Hence, the local evidences and analysis are more relevant in the case of intergenerational mobility (IGM) of occupation. The present paper examines the role of remittance regarding IGM of occupation with reference to structural upward mobility (SUM, by enjoying existing structural opportunities) and exchange upward mobility (EUM, which is a reflection of policy interventions and affirmative action) between 2004–2005 and 2010–2011, to understand the equalisation effect of remittances across the social group.

We identify the causal impact of housing demolition on employment and occupational mobility of working-age individuals in China. We exploit housing demolition events as a quasi-natural experiment and apply a two-way fixed effects approach to overcome the potential endogeneity problem. Using data from the CHFS, we find that on the extensive margin, housing demolition creates skill waste by making individuals less likely to work; while on the intensive margin, housing demolition leads to upward occupational mobility, especially among low-skilled workers. We do not find any empirical evidence that housing demolition influences internal migration flow or migrant workers' occupational mobility. [ABSTRACT FROM AUTHOR]

Using administrative data for the period 2005-2010, we test for the existence of segmentation in the pool of the unemployed receiving benefits and investigate the factors associated with the duration and recurrence of the receipt of unemployment benefits in Spain. The results suggest the existence of (at least) three groups of individuals, each with different combinations of covered unemployment duration and recurrence. We also find that the impact of the employment crisis has been an increase in the average length of time spent receiving unemployment benefits and the recurrence. Our findings support the hypothesis that not only the heterogeneity but also the previous experience of receipt increase the expected duration of subsequent benefit periods. [ABSTRACT FROM AUTHOR]

This paper analyses changes in job opportunities of older workers in the Netherlands in the period 1996-2010. The standard human capital model predicts that, as a result of human capital obsolescence, mobility becomes more costly when workers become older. We measure and interpret how changing job opportunities across 96 occupations affect different age and skill groups. Older workers end up in shrinking occupations, in occupations with a lower share of high-skilled workers, in occupations facing a higher threat of offshoring tasks abroad, more focus on routine-intensive tasks and less rewarding job content. This process is not only observed for the oldest group of workers, but for workers aged 40 and above. Observing older workers in declining occupations is to a large extent a market outcome, but declining job opportunities in terms of less satisfying working conditions and job tasks and content could potentially raise incentives to retire early.

This paper analyzes the impact of academic inbreeding in relation to academic research, and proposes a new conceptual framework for its analysis. We find that mobility (or lack of) at the early research career stage is decisive in influencing academic behaviors and scientific productivity. Less mobile academics have more inward oriented information exchange dynamics and lower scientific productivity. The analysis also indicates that the information exchange and scientific productivity of academics that changed institutions only once do not differ substantially from that of 'mobile inbred academics'. This emphasizes the need for mobility throughout scientific and academic careers and calls for policies to curtail academic inbreeding. [ABSTRACT FROM AUTHOR]

This paper reflects on the results of a job satisfaction study of small-scale fishers in the Dominican Republic. The survey results suggest that, although fishers are generally satisfied with their occupations, they also have serious concerns. These concerns include anxieties about the level of earnings, the condition of marine resources and the performance of government officials engaged in management. Such worries are offset, at least to some degree, by high levels of satisfaction regarding the communities of which respondents are part, as well as the healthfulness and worth of the job. The ambivalence characterising fishers' views of their occupation carries through in their responses to general questions on willingness to shift to another type of fishing, leave the occupation altogether and advise young persons to enter fishing. However, the survey results also indicate significant variation between different parts of the coastline. [ABSTRACT FROM AUTHOR]
