Recent work by David Lilien has argued that the existence of a strong positive correlation between the dispersion of employment growth rates across sectors (G) and the unemployment rate implies that shifts in demand from some sectors to others are responsible for a substantial fraction of...

This paper reports new evidence from a survey of over 408 U.S. employers concerning their use of temporary and on-call workers. More than 90 percent of responding organizations reported reliance on these flexible staffing arrangements. They accounted for an average of 1.5 percent of total labor...

This paper surveys recent developments in the literature on efficiency wage theories of unemployment. Efficiency wage models have in common the property that in equilibrium firms may find it profitable to pay wages in excess of market clearing. High wages can help reduce turnover, elicit worker...

This paper shows that the prospect of recall to previous employer is important for a significant number of the unemployed in the United States and that taking into account the possibility of recalls has important implications for the study of unemployment spell durations. A job search model that...

Wage subsidies to private employers have often been proposed by economists as a potentially flexible and efficient method to improve the earnings and employment of low-wage workers. This paper lays out the basic economics of wage subsidies; examines issues arising in the design of alternative...

The stylized fact that seniority and earnings in a cross-section are positively related, even after controlling for total labor market experience, has served as the basis for theoretical analyses of implicit labor contracts suggesting that workers post bonds in the form of deferred compensation...

This study provides evidence which we believe challenges some conventional assumptions about the promotion process. Based on survey information collected from a large random sample of U.S. private sector firms, we reach two main conclusions. First,seniority independent of productivity appears to...

This paper presents new survey evidence that relative protection against job loss grows with length of service, independent of their net value to the firm. This protection makes good sense given that at most companies employees appear to earn less than their value marginal product in the early...

This paper presents a summary of the evidence which has recently been collected concerning the role of length of service in the operation of internal labor markets. It argues that these data are inconsistent with the human capital model of the experience-earnings and experience-layoff...

This paper presents two key facts which call into question the value of unemployment rates as barometers of labor market tightness. First, while both unemployment rates and unsatisfied labor demand proxies perform reasonably well on their own in compensation growth equations, in models which...
