The article is devoted to the adaptation of Engel's curve tools for evaluating the wellbeing of Ukrainian households. In particular, the assessment of the welfare inequality, observed between households with the lowest equivalent per capita income and the most affluent households, as well as the main trends in the change of the consumption structure for the period 2014-2020. The research is based on the concept that overcoming the concentration of consumer spending around the purchase of food is a necessary condition for the launch of microeconomic mechanisms of socio-economic development because it allows households to actively invest in the accumulation of human capital and thus overcomes the monopoly of budget financing of social sphere industries. To assess the level of satisfaction with food needs, the Engel line "income - food consumption" was constructed and the coefficient of elasticity of food consumption from income was determined. Similar calculations were made concerning the consumption of goods created by the educational sector. According to the results of the Engel function development, the income elasticity of the absolute amount of food consumption is equal to 0.47: an additional percentage of income encourages households to increase the amount of food consumption by 0.47%. According to our calculations, the income elasticity of educational goods consumption is equal to 0.928 (an additional percentage of real income encourages Ukrainian households to increase the amount of educational goods consumption by 0.93%). Therefore, Ukrainian households value education enough and tend to use economic opportunities (income released from priority needs satisfaction) for expanding education consumption. Both assessments of elasticity coefficients indicate that the achieved level of meeting food needs for the vast majority of Ukrainian households does not allow them to count on the release of their funds from meeting basic current needs and the expansion of those expenses that have the character of investing in human capital and have a pronounced positive impact on the qualification level of labor resources and the productivity of their use in the national economy.

The article is devoted to the development of tools for evaluating the level and dynamics of Ukrainian households' well-being, by considering the availability of key groups of goods for households with different levels of per capita income. The results should contribute to taking into account a greater number of essential aspects of the households lifestyle and economic capabilities for assessing the achieved level of well-being, its dynamics, the differences of its components for different population groups, allowing to make policy and programs for its implementation more sensitive to the real needs of different aim groups. Engel's curves (defined by the linear form of consumption dependence on income – Working's function) and income elasticity of consumption were used to assess the degree of satisfaction of needs in two commodities, which are key for assessing the households' well-being. It was evidenced, that the still high (more than two times higher than in developed countries) income elasticity of food consumption indicates the extreme limitation of the resource provision for investing in the development of human capital by the households. At the same time, the propensity of households to invest additional income in the purchase of goods created in healthcare is quite high – at the level of developed countries. More affluent households (which were expected to have a higher income elasticity of healthcare goods consumption) are more actively using the advances of insurance medicine, while less affluent households still rely only on "out-of-pocket" healthcare costs. So, relatively poorer households are faced a clear lack of resources to meet their needs: the absolute amount of healthcare goods consumption for the least wealthy households is reduced against the background of the increase in the share of relevant expenses in the composition of consumer spending.

Why are price levels in Germany lower than in Switzerland despite comparable productivity levels and the possibility of goods arbitrage in this region? Standard theories in macroeconomics have severe difficulties in explaining this theoretically important outlier. We construct a dataset of 73 developed and developing countries to highlight the tight connection between price levels, product quality, and household wealth. We find that wealth per capita has a 20 percentage points higher explanatory power than income per capita — the key variable implied by standard theories. Analyzing more than 4000 product import categories, we find that Swiss unit values are more than twice as high as German unit values in the median product category. We then provide a theory linking these three forces. Wealth induces consumption shifts toward more expensive goods. As official price statistics tend to underestimate quality improvements, they overstate prices. In turn, higher product quality that comes with higher wealth inflates prices and thus contributes toward explaining price level differences across countries. [ABSTRACT FROM AUTHOR]

The aim of the article is expenditures analysis as a component of estimation of household financial condition. The results of the study were obtained according to the State Statistics Service of Ukraine on household expenditures for 2010-2020. In the process, the analysis was used as a method of theoretical knowledge of phenomena. Comparisons and measurements are used as empirical methods for the study. The existing approaches of domestic scientists and the methodology of the State Statistics Service of Ukraine on the nature and classification of household expenditures are analyzed. The Engel coefficient is proposed as an indicator of the estimation of the financial condition of the household and its value is calculated. Törnqvist functions for domestic households are built based on data on the composition and structure of expenditures. Engel's law and L. Törnqvist's functions allowed us to extrapolate to the sphere of household finance the conclusion that despite the increase in expenditures in absolute terms by more than three times, the financial condition of domestic households has not improved significantly. Construction of a linear function of the relationship between household food expenditures and factors of internal and external factors influencing their size; calculation of the direction and strength of their interaction through indicators of elasticity, correlation, and variance opens up prospects for further research in this area of financial science.

In studying individual consumption behavior, an important issue is the analysis of the relation between commodity expenditure and income. The subject of this paper is the analysis of clothing, footwear and housing consumption of households in Bosnia and Herzegovina. The aim of this paper is to quantify the impact of income on household expenditure for clothing, footwear and housing, with a focus on examining the validity of Second Engel's law in Bosnia and Herzegovina. Empirical research is based on the econometric modeling of Engel curves applying single equation modeling, using microdata from the Household Budget Surveys in Bosnia and Herzegovina, which are available for four years (2004, 2007, 2011, 2015). The surveys were carried out using the uniform methodology developed by the Statistical Office of the European Union (EUROSTAT). In order to achieve the research objective, six functional forms of Engel curves have been formulated and estimated. The intensity of the impact of income on relative changes in consumption was measured using income elasticities. Based on the estimated parameters and income elasticities derived from them, the hypothesis of unit elasticity of demand for the mentioned product groups in relation to household income was tested. Empirically estimated values of elasticities imply that the validity of the Second Engel's law in Bosnia and Herzegovina was partially confirmed: while clothing and footwear expenditures became elastic over time, expenditures for housing are inelastic in observed years. By comparing the estimated elasticities for different years in which the survey was conducted, it was revealed whether there were significant changes in the preferences of households in Bosnia and Herzegovina in the observed period.

This article examines the drivers of the long‐run structural transformation in Japan. It uses a dynamic input–output framework that decomposes the reallocation of the total output across sectors into two components: the demand side and the supply side, or technological change. To perform this task, we employ 13 seven‐sector input–output tables spanning 100 years (1885 to 1985). The results show that the demand‐side factors, as a combination of the Baumol and Engel effects, were the key explanatory factors in more than 60 per cent of the sector‐period cases in the pre‐Second World War period, while the supply‐side effect drove structural transformation in more than 75 per cent of such cases in the post‐Second World War period. Detailed decomposition results suggest that in most of the sectors, changes in private consumption were the dominant force behind the demand‐side explanations. The demand effect was found to be strongest in the commerce and services sector, which contributed to the rapid growth of GDP in Japan throughout the twentieth century. [ABSTRACT FROM AUTHOR]

In typical developing countries, a one-size-fits-all policies often tend to hurt the poor and vulnerable. Specifically, in food demand studies different social groupings have characteristically heterogeneous demand functions which may require unique attention in terms of food policies. In this paper, we examine the food demand characteristics of three categories of consumers in Ghana based on fourteen selected food commodity groups. We use the sixth round of the Ghana Living Standard Survey in 2012/2013 data collected by the Ghana Statistical Service in collaboration with the World Bank. We apply the Quadratic Almost Ideal Demand System (QUAIDS) to estimate price and expenditure elasticities of demand for food in both rural and urban areas in Ghana. Empirically, we find that fish and cereal products take close to half (about 46%) of the food budget of the average Ghanaian household. We also report heterogeneous food expenditure patterns across the six regions considered in the study. Surprisingly, we find that female-headed households disburse a higher proportion on food budget than their male counterparts. Also, in conformity to theory, we find that the very poor households allocate the highest proportion to food budget than the non-poor. These findings suggest that food policies in Ghana should be discriminately on social and geographical lines to protect the very poor from escalating food prices. Food aid and assistance programmes should target the aged, larger and very poor households and rural dwellers.

Optimism and pessimism influence economic choices. If consumers are optimistic, they tend to spend a greater proportion of their budget shares on luxuries and a lesser proportion on necessities. Many models of consumer expenditure do not take into account the influence of optimism and pessimism. This paper demonstrates a way to indirectly measure optimism and pessimism by focusing on patterns in Engel curve residuals for necessities and luxuries. Using the revised International Comparison Program (ICP) 2005 data covering 144 countries, this paper presents economy‐wide optimism and pessimism indicators. These indicators provide a useful complement to traditional economic measures of standard of living such as real gross domestic product (GDP) in purchasing power parity (PPP) terms. These indicators are non‐economic in traditional terms. However, since they are constructed as residuals from an economic analysis, they could act as a very useful complement to traditional economic indicators and, as such, may be termed "quality of life" indicators.

In this study, the impact of different food groups' consumption, social and economic indicator on the share of food in household expenditure in the rural and urban area of Iran investigated. For this purpose, panel quantile regression considered as the best technique. The results indicated that the impact of social and economic indicators and food groups' consumption varies in different quantiles. Moreover, between social and economic variables, income, food price index and literacy rate considered as the most effective determinants of food expenditure in rural and urban areas. Furthermore, consumption of cereal and dairy in a rural area and cereal and vegetables in an urban area do not affect the household's food expenditure; on the other hand, increase in consumption of meat and crop oils in rural and urban area upsurge the share of food in the household expenditure. Based on the results, the implication of policies, which lead to household income improvement and stabilized the food price can improve food availability in both rural and urban areas. Besides, the introduction of the innovative and stable method of dairy and vegetable production in a rural area and encouraging the urban household to consume more vegetables results in more diverse diet and enhance the food security and simultaneously don't increase the share of food in household expenditure.

The aim of the paper is to test the valability of Engel's law in the Romanian consumption dynamics after 1990. We used NIS ad EUROSTAT data to interpret the dynamics of the households' income and consumption expenditures and its structure by destinations. We explored the relationship between consumption and income through the regression analysis and found that the Engel's law applies in the Romanian economy, since 1990 to 2016, with specific evolutions and influences.

This study aims to (1) determine the proportion of food cost to total household expenditure of farmers in Padang according to income groups, (2) determine the level of consumption of food (energy and protein) household farmers in Padang based on income level and (3) analyze conditions of household food security of farmers in Padang according to the income group. This research using survey method, whereas the data used includes primary and secondary data. Secondary data was obtained from the results of publications and information related to food security, while primary data was obtained through direct interviews with household members of farmers. The number of research samples was 60 households. Data analysis was done by disaggregation of household groups into low, medium and high groupings. The results showed that the characteristics of household farmers in the low, medium and high groups are not significantly different. Whereas in the average proportion of food cost to total expenditure has decreased, where in the level of low income to the proportion of food cost was 64%, medium was 62% and high was 61%. The level of consumption of food (energy and protein) at home based on the low, medium and high income level are dominant in good conditions, such as 70.83%, 62.50% and 100%. The condition of household food security in the high income level group was better where there are no more households with the condition of food insecure and insufficient households. According to Engel's Law, are the higher income of a person (household), then the percentage of cost on food will be smaller as evidenced in this study. [ABSTRACT FROM AUTHOR]

The article provides an analysis of investment portfolio separation and myopia using microeconomics, particularly Engel curves, budget lines, and indifference curves. The investor's decision problem is discussed through a hypothetical investor who is interested in maximizing the expected return of a concave utility function in a short time in the securities market. A number of theorems and proofs are presented that show that the conditions that are needed for portfolio separation are also needed for myopia.

Engel's Laws and the concept of social class developed by Pierre Martineau have in recent years become increasingly important to those concerned with segmenting markets. In this article, the author suggests that marketers have not really begun to make effective use of the social class concept. He further suggests that substantial data now exist which would permit the use of social class criteria other than income class. [ABSTRACT FROM AUTHOR]

In recent years the validity of Engel's Laws, with reference to consumption expenditures, has been open to question. The first law was stated in 1857 in Western Europe where economic conditions were much different from today. Do the laws still hold in a mature American economy? This article discusses results from a test using income elasticity as the method. Data were supplied by the 1960-61 study of the Bureau of Labor Statistics. [ABSTRACT FROM AUTHOR]

The article presents analysis of consumer spending, specifically focusing on the relations between income and discretionary spending. The work of German statistician Ernst Engel is referenced as a foundation for much research in consumer expenditure forecasting. Engel is credited with theorizing rules for the relationship income has on spending for clothing, food, health, recreation, luxury goods, rent and utilities. The article addresses the question of whether these consumer expenditure theories apply over extended periods of time.

The purpose of this research is detection of characteristic features and regularities in food consumption by the population of the Arkhangelsk region on the basis of statistical estimation of such econometric indicators as the growth rate of food expenditures with change of the income of households of this population, and also income elasticity of expenditures and income elasticity of a share of food expenditures. For calculation of these indicators the nonlinear one-factorial regression model describing interrelation of the income and food expenditures of the population of the Arkhangelsk region was offered. In the paper the considerable attention is paid to check of accomplishment of conditions of reliability and importance of this regression model. For carrying out the statistical analysis microdata of selective examinations of budgets of the households of the Arkhangelsk region for the IV quarter of 2012 conducted by Rosstat were used. For data processing the packet of the statistical analysis of SPSS was used, and the solution of objectives was performed by methods of the correlation and regression analysis, and also by means of check of distributions of the researched quantities to a normality and the analysis of a regression residuals. During the research double logarithmic regression model was developed and statistically significant equation of regression which adequately describes interrelation of an income and food expenditures of households of the Arkhangelsk region is received. Proceeding from the received regression equation, income elasticities of expenditures and of a share of food expenditures were calculated: value of elasticity of the first size showed that in case of increase in incomes of the population of the Arkhangelsk region by 1% food expenditures increase on average for 0,5%, the received negative value of elasticity of a share of food expenditures demonstrates that in case of increase in incomes of this population by 1% the share of food expenditures decreases on average for 0,5%. On the basis of the carried-out regression analysis where, in addition, special attention was paid to check of observance of necessary conditions for its application, and estimation of the corresponding econometric indicators, it is possible to draw the following conclusions on food consumption by the population of the Arkhangelsk region: with increase in income food expenditures of households also increase, however the growth rate of such expenditures decreases; owing to income elasticity of expenditures, small in comparison with unit, food for the population of the Arkhangelsk region are essential goods; at last, food consumption by this population is in a consent with the economic Engel’s law determining dependence of a share of food expenditures in volume of incomes of households on their level.

Increasing income brings about a decline in the relative importance of food consumption, a wider spread of spending patterns, and a demand for higher-quality goods. Using an index-number approach, this article analyzes these three closely-related tendencies. Stripping out the impact of prices from the dispersion of food expenditures gives a volume-based measure of diet diversity that is relevant for nutrition. Using unpublished data from the World Bank's International Comparison Program for 31 items of food in more than 150 countries, we find that diets of rich countries are substantially more diverse than those of the poor; and that volumes are the more appropriate way to measure the inequality of diversity. The quality of the food basket, based on the luxury-necessity distinction of consumption, increases with income, but the elasticity is small. There is a modest tendency for the structure of prices to be regressive since prices of luxuries relative to necessities are lower in richer countries. Additionally, our diversity and quality measures are shown to have implications for demand analysis and well-being. [ABSTRACT FROM AUTHOR]

This paper presents an economy-wide consumer expectations indicator that reflects different degrees of optimism or pessimism with respect to consumers' confidence in their economy. The indicator provides a useful complement to traditional economic indicators that are frequently used to compare countries, such as gross domestic product (GDP) in purchasing power parity (PPP) terms. Our indicator may be seen as representing the influence of social wealth on economic behavior-that is, of effects left out of a standard economic analysis. We use a theoretical approach to integrate the expectations measure with the International Comparison Program's (ICP) PPP GDP statistics which produces a measure we term 'effective GDP.' Compared to the ICP's PPP figures, the measure of 'effective GDP' differs from the ICP's PPP estimates by as much as four to five percent in the positive direction for apparently optimistic countries and as much as two percent downwards for pessimists.

We consider the efficiency of approximating real numbers by their convergents of Engel continued fractions (ECF). Specifically, we estimate the Hausdorff dimension of the set of points whose ECF-convergents are the best approximations infinitely often. We also obtain the Hausdorff dimensions of the Jarnik-like set and the related sets defined by some growth rates of partial quotients in ECF expansions. [ABSTRACT FROM AUTHOR]

This article examines the long-term impact of government intervention and sectoral productivity on structural transformation. We construct a multi-sector Dynamic General Equilibrium model that explicitly incorporates government intervention as a force of structural transformation. The government affects the economy through taxation and lump sum transfers. We show that in the steady state, a reduction in the tax rate and an increase in sectoral productivity will decrease the agricultural employment share, and when nonhomotheticity of preference is strong enough, these changes can also increase the share of services employment.

In this regard, by a normal Engel fuzzy subpolygroup of and , the fundamental relation on a given polygroup , we construct an Engel fuzzy subgroup . We obtain a necessary and sufficient condition between Engel fuzzy subpolygroups and the Engel group /, the group of equivalence classes derived from a fuzzy subpolygroup of . Finally, by using these results, we get Zorn's lemma, in the Engel fuzzy subpolygroups. [ABSTRACT FROM AUTHOR]

We estimate the CPI bias in Korea by employing the approach of Engel’s Law as suggested by Hamilton (2001). This paper is the first attempt to estimate the bias using Korean panel data, Korean Labor and Income Panel Study(KLIPS). Following Hamilton’s model with non­linear specification correction, our estimation result shows that the cumulative CPI bias over the sample period (2000-2005) was 0.7 percent annually. This CPI bias implies that about 21 percent of the inflation rate during the period can be attributed to the bias. In light of purchasing power parity, we provide an interpretation of the estimated bias.

Engel's law expresses a “negative stochastic association” of income and the proportion of income that is spent on food. However, there are many quite different notions of “negative stochastic association” and consequently there are different ways of defining Engel's law. We relate these different concepts to Engel's original statistical analysis and show that one must give credit to Engel for the first non-parametric statistical analysis of budget-data.

After 2005, commodity prices experienced their longest and broadest boom since World War II. Agricultural prices have now come down considerably since their 2011 peak, but are still 40% higher in real terms than their 2000 lows. This paper briefly addresses the main arguments on the causes of the agricultural price cycle. It broadens the scope of analysis by focusing on six agricultural commodities, and identifies the relative weights of key quantifiable drivers of their prices. It concludes that increases in real income negatively affect real agricultural prices, consistent with the Prebisch-Singer hypothesis and its predecessor, Engel's Law. Energy prices matter most (not surprisingly, given the energy-intensive nature of agriculture), followed by stock-to-use ratios and, to a lesser extent, ex-change rate movements. The cost of capital affects prices only marginally, probably because it not only influences demand, but also evokes a supply response. The added value of these results lies in that, when examined in tandem and against market fundamentals, they challenge the conclusions from uni-dimensional approaches that often put disproportionate weight on an individual factor.

Income growth in emerging economies has been often cited as a key driver of the past decade's commodity price boom--the longest and broadest boom since World War II. This article shows that income has a negative and highly significant effect on real food commodity prices, a finding that is consistent with Engel's law and Kindleberger's thesis, the predecessors of the Prebisch-Singer hypothesis. The article also shows that in the long run, income influences real food prices mainly through the manufacturing price channel (the deflator), hence weakening the view that income growth exerts strong upwards pressure on food prices. Other (short-term) drivers of food prices include energy costs, inventories, and monetary conditions. [ABSTRACT FROM AUTHOR]

In many countries, the definition of near poverty line is the given amount that is slightly above the poverty line, but the precise economic and statistical basis is unknown. In order to find a natural candidate of near poverty line, this paper employs robust quantile regression on a quadratic parametric model of Engel's law to investigate changes in curvature, signifying changes in taste or liquidity constraint, across food share quantiles. By analyzing thirty waves ofthe Survey of Family Income and Expenditure in Taiwan(1980–2009), it finds that the curvature systematically follows the ‘bifocal’ variation, indicating a perceptible break in consumption behavior. The threshold separating the two food consumption patterns provides a natural candidate of near poverty line of Taiwan. [ABSTRACT FROM AUTHOR]

The article deals with the analysis of the shape of the Engel's curve in the field of the expenditures for meat and meat products. Within the analysis, the paper is especially focused on the initial growth phase of the Engel's curve. The CSO data of the average Czech household was used for the research. For the elimination of the price impacts in this income-expenditure analysis, the original CSO data on nominal level were transformed into the real level. The studied real shares were determined with respect to the total food expenditures and also with respect to the total households' incomes. The linear and the quadratic forms of the dynamic Engels' models were developed for the aims of the research. Besides the trend development, the periodical component was investigated. Regression analysis was fully confirmed the validity of the Engel's law in the field of the Czech-household expenditures for meat and meat products. Furthermore, the quadratic model form showed the existence of the initial growth phase of the examined Engel's curve. In case of the real share with respect to the total food expenditures by the model:rw1t* = (–1,0176E – 08) · (rmt*)2 + (2,8498E – 04) · rmt* + [(–1,7011E + 00) + (1,3970E – 03) · t],the size of the real household income is 14 003 CZK. For the second analysed share of the real expenditures with respect to the total households’ incomes, the real level of the income by the developed model:rw2t* = (–2,8844E – 09) · (rmt*)2 + (7,8205E – 05) · rmt* + [(–4,6323E + 01) + (3,1095E – 04) · t]the value was 13 557 CZK.

The paper analyses changes in consumer standard of living in the Czech Republic from 2010 to 2013 resulting from the Czech Statistical Office's annual survey "Expenditures and Consumption of Households Included in Household Budgets". Based on revealed preference theory and index theory (Paasche and Laspeyres price and quantitative indices), consumer standard of living is evaluated both in general and according to single economic activity categories, i.e. employees with higher and lower education, the self-employed, unemployed consumers and pensioners. The results are compared and discussed with conclusions ensuing from Engel's law. [ABSTRACT FROM AUTHOR]

Households tend to diversify their spending across a wide range of goods and services as they become more affluent. Recently, there has been growing interest in understanding the precise manner in which this spending diversification process takes place. We review what facts are known about this process and the underlying behavioural tendencies that are thought to drive it. In addition, we clarify the relationship between different approaches to measuring the level of spending diversity. A number of indices are employed, including measures based on joint probabilities, distances and the concept of entropy. Using UK household spending data, we show the extent to which these measures deliver different results and shed light on the nature of behavioural heterogeneity. [ABSTRACT FROM AUTHOR]

In this paper, we report a replication of Engel's (Exp. Econ. 14(4):583-610, ) meta-study of dictator game experiments. We find Engel's meta-study of dictator game experiments to be robust, with one important exception: the coding of the take-option (List in J. Polit. Econ. 115(3):482-493, ; Bardsley in Exp. Econ. 11(2):122-133, ; Cappelen et al. in Econ. Lett. 118(2):280-283, ). While Engel reports this as having no statistically significant effect, in our replications, we find an economically and statistically significant negative effect on giving in line with the relevant literature.

This paper presents an approach to recognize key factors in data classification. Using collinearity diagnostics to delete the factors of repeated information and Logistic regression significant discriminant to select the factors which can effectively distinguish the two kinds of samples, this paper creates a model for recognizing key factors. The proposed model is demonstrated by using the 2044 observations in finical engineering. The experimental results demonstrate that the 13 indicators such as "marital status," "net income of borrower," and "Engel's coefficient" are the key factors to distinguish the good customers from the bad customers. By analyzing the experimental results, the performance of the proposed model is verified. Moreover, the proposed method is simple and easy to be implemented. [ABSTRACT FROM AUTHOR]

Using a collective model of consumption, we characterize optimal commodity taxes aimed at targeting specific individuals within the household. The main message is that distortionary indirect taxation can circumvent the agency problem of the household. Essentially, taxation should discourage less the consumption of a certain group of goods-those for which the slope of the Engel curves is larger for the targeted person. [ABSTRACT FROM AUTHOR]

Highlights: [•] Extending Engel's original analysis, the paper structurally assesses general changes in budget shares across countries. [•] The distinction between luxuries and necessities rests upon behavioral foundations. [•] The distinction can be traced back to the differing satiation features of the underlying universally shared needs. [•] Expenditure categories that can be associated with easily satiable needs show decreasing cross-country budget share Engel curves. [•] Expenditure categories that can be associated with hardly satiable needs of nonhomeostatic nature lead to increasing cross-country budget share Engel curves. [ABSTRACT FROM AUTHOR]

This paper presents a formal model in which differential satiation dynamics of various consumer needs explain (not only describe) the shapes of Engel curves. In the model, individuals allocate their income to various consumption categories proportional to corresponding need deprivation states, a decision making process called matching. The model allows explaining some empirical regularities that other models have difficulties accounting for. It can, for example, reconstruct that income elasticities for food tend to decrease with rising income, and that goods that are luxuries at relatively low income levels can become necessities at higher income levels. Moreover, the paper compares the Engel curves obtained from the matching model with Engel curves obtained from a utility maximization model. While both types of Engel curves are relatively similar at high income levels, at lower income levels matching and maximization lead to very different allocations of income. The paper shows that a given amount of income redistribution leads to less additional welfare when individuals follow matching behavior than when they maximize their utility. Accordingly, to obtain a given amount of additional welfare more income redistribution is needed than a policy maker who (mistakenly) assumes that individuals rationally maximize their utility predicts.

In this paper we present some results about subgroup which is generalization of the sub- group R⊗ 2 (G) = {a ∈ G∣[a; g] ⊗ g = 1⊗ , ∀g ڰ G} of right 2⊗ -Engel elements of a given group G. If p is an odd prime, then with the help of these results, we obtain some results about tensor squares of p-groups satisfying the law [x; g; y] ⊗ g = 1⊗ϵ , for all x; g; y ϵ G. In particular p-groups satisfying the law [x; g; y] ⊗ g = 1 ⊗ have abelian tensor squares. Moreo⊗ver, we can determine tensor squares of two-generator p-groups of class three satisfying the law [x; g; y] ⊗ g = 1⊗. [ABSTRACT FROM AUTHOR]

In response to the Deaton and Dreze (2009) explanation of a downward shift in the calorie Engel curve in terms of lower requirements due to health improvements and lower activity levels in India, we develop an alternative explanation embedded in a standard demand theory framework, with food prices and expenditure (as a proxy for income) cast in a pivotal role. We find robust food price and expenditure effects and shifting food price elasticities. There are shifts in demands due to factors other than lower requirements. So, while the Deaton and Dreze (2009) explanation is not rejected, it is arguable that it is complementary to the demand based explanations. [ABSTRACT FROM AUTHOR]

How did Europe escape the “Iron Law of Wages?” We construct a simple Malthusian model with two sectors and multiple steady states, and use it to explain why European per capita incomes and urbanization rates increased during the period 1350–1700. Productivity growth can only explain a small fraction of the rise in output per capita. Population dynamics—changes of the birth and death schedules—were far more important determinants of steady states. We show how a major shock to population can trigger a transition to a new steady state with higher per-capita income. The Black Death was such a shock, raising wages substantially. Because of Engel's Law, demand for urban products increased, and urban centers grew in size. European cities were unhealthy, and rising urbanization pushed up aggregate death rates. This effect was reinforced by diseases spread through war, financed by higher tax revenues. In addition, rising trade also spread diseases. In this way higher wages themselves reduced population pressure. We show in a calibration exercise that our model can account for the sustained rise in European urbanization as well as permanently higher per capita incomes in 1700, without technological change. Wars contributed importantly to the “Rise of Europe”, even if they had negative short-run effects. We thus trace Europe's precocious rise to economic riches to interactions of the plague shock with the belligerent political environment and the nature of cities. [ABSTRACT FROM PUBLISHER]

Abstract: Community-Based Health Insurance (CBHI) (a.k.a. micro health insurance) is a contributory health insurance among rural poor in developing countries. As CBHI schemes typically function with no subsidy income, the schemes'' expenditures cannot exceed their premium income. A good estimate of Willingness-To-Pay (WTP) among the target population affiliating on a voluntary basis is therefore essential for package design. Previous estimates of WTP reported materially and significantly different WTP levels across locations (even within one state), making it necessity to base estimates on household surveys. This is time-consuming and expensive. This study seeks to identify a coherent anchor for local estimation of WTP without having to rely on household surveys in each CBHI implementation. Using data collected in 2008–2010 among rural poor households in six locations in India (total 7874 households), we found that in all locations WTP expressed as percentage of income decreases with household income. This reminds of Engel''s law on food expenditures. We checked several possible anchors: overall income, discretionary income and food expenditures. We compared WTP expressed as percentage of these anchors, by calculating the Coefficient of Variation (for inter-community variation) and Concentration indices (for intra-community variation). The Coefficient of variation was 0.36, 0.43 and 0.50 for WTP as percent of food expenditures, overall income and discretionary income, respectively. In all locations the concentration index for WTP as percentage of food expenditures was the lowest. Thus, food expenditures had the most consistent relationship with WTP within each location and across the six locations. These findings indicate that like food, health insurance is considered a necessity good even by people with very low income and no prior experience with health insurance. We conclude that the level of WTP could be estimated based on each community''s food expenditures, and that this information can be obtained everywhere without having to conduct household surveys.

Using UK household expenditure data spanning over four decades (1960-2000), this paper employs Engel's needs-based approach to analyzing household expenditure patterns and finds evidence for the existence of a stable hierarchy of expenditure patterns at low levels of household income. Second, we investigate how rising household income influences the manner in which total expenditure is distributed across Engel's expenditure categories. Our results suggest that i) total household expenditure is distributed across Engel's expenditure categories in an increasingly even manner as household income increases and ii) over time, there has been an acceleration in the rate at which household expenditure patterns become diversified as household income rises. Finally, we consider how the shape of Engel Curves may help shed light on the relationship between goods and the underlying needs they serve. [ABSTRACT FROM AUTHOR]

We study food Engel curves amongst the poor population targeted by a conditional cash transfer programme in Colombia. After controlling for the endogeneity of total consumption and for the price variability across villages, our estimates imply that an increase in consumption by 10% would lead to a decrease of 1% in the share of food. However, quasi-experimental estimates of the impact of the programme show that the share of food increases. This result is not inconsistent with the hypothesis that the programme could increase the bargaining power of women, inducing a more than proportional increase in food consumption.
