We uniquely introduce convex production costs into a cartel model involving spatial price discrimination. We demonstrate that greater convexity improves cartel stability and that for sufficient convexity first best locations will be adopted. We show that allowing locations to vary over the game reduces cartel stability but that greater convexity continues to improve that stability. Moreover, when the degree of convexity does not support the first best collusive locations, other collusive locations exist that require less stability and these may either increase or decrease social welfare relative to competition. Critically, these locations that require less stability are more dispersed in sharp contrast to the known result assuming linear production costs.

We examine the hypothesis that flexible work organization involves greater skill requirements and, hence, an increased likelihood of receiving employer provided training. Using unique linked employer-employee data from Germany, we confirm that employees are more likely to receive training when their jobs are characterized by greater decision-making autonomy and task variety, two essential elements of flexibility. Critically, the training associated with workplace flexibility does not simply reflect technology. Skill-biased organizational change plays its own role. Moreover, we show that the training associated with workplace flexibility is disproportionately oriented toward employees with a greater formal education. Our results also provide modest evidence of an age bias of workplace flexibility. However, the link between workplace flexibility and training does not appear to differ by gender.

This paper tests whether the job security offered by stricter employment protection legislation (EPL) undermines positive compensating wage differentials that would otherwise be paid. Specifically, we ask whether industries with relatively more need for layoffs and labour flexibility have lower wages in countries where stricter EPL protects workers from layoffs. We find this generally to be true for a large sample of industries in the major OECD countries over 1984-2005, particularly for wages of unskilled workers. However, we also find that where workers are well organised, they can take advantage of EPL to secure higher wages.

Using the original data source of Clark, we show that over the last two decades the female satisfaction gap he documented has vanished. This reflects a strong secular decline in female job satisfaction. This decline happened both because younger women became less satisfied as they aged, and because new female workers entered with lower job satisfaction than their early 1990s peers. Decompositions make clear that the decline does not reflect changing job characteristics for women but rather their increasingly less favourable evaluation of job characteristics. These findings fit with the suggestion that women in the early 1990s had a gap between their labour market expectations and actual experience that has since closed and that the gender satisfaction gap has vanished as a consequence.

Using German establishment data, this paper examines the relationship between product market competition and the extent of employer provided training. We demonstrate that high product market competition is associated with increased training except when the competition is so severe as to threaten liquidation to a firm. We take this as evidence of an inverted U-shaped relationship. We also make clear that while this relationship is very evident for the service sector it is largely missing for manufacturing where we confirm earlier results of no relationship.

We uniquely examine the relationship between firm-sponsored training and product quality competition. Using an oligopolistic model of both price and quality competition, we show that an increase in the sensitivity of demand to product quality will strengthen firms’ incentives to train their workforce. Cross section, panel and instrumental variable estimations confirm that British establishments provide more intensive training when their competitive position is more sensitive to product quality. A variety of robustness checks and changes in variable definitions leave this confirmation in place.

Using British linked employer-employee data, we show that the establishment size effect for supervisors is approximately twice that for non-supervisors. This difference is routinely statistically significant, not explained by other controls and is an important determinant of the difference in earnings between supervisors and non-supervisors. Moreover, we use separate British longitudinal data to confirm both the statistically different effect and that it is not explained by worker fixed effects. Event study evidence and information on skill match suggest that the larger return to supervisors reflects, in large part, match specific returns supporting the view that talented supervisors receive a return on that talent only with larger employers.

This work contributes to the literature demonstrating an important role for psychological traits in labor market decisions. We show that West German workers with an internal locus of control sort into jobs with performance appraisals. Appraisals provide workers who believe they control their environment a tool to demonstrate their value and achieve their goals. We confirm that workers who are risk tolerant also sort into jobs with performance appraisals but explain why the influence of the locus of control and risk tolerance should not be additive. We demonstrate this by estimating a routinely large and significantly negative interaction in our sorting equations. We also show that important patterns of sorting are revealed only when taking into account the interaction of locus of control and risk tolerance.
