This paper empirically examines the importance of explicitly accounting for the layoff-rehire process in the analysis of unemployment outcomes in the United States. We find that the spells of individuals' who initially expect to be recalled account for much more of the unemployment of unemployment insurance (UI) recipients than do spells actually ending in recall. Our results indicate that the recall and new job escape rates from unemployment have quite different time patterns and are often affected in opposite ways by explanatory variables. We also find that the probability of leaving unemployment both through recalls and new job finding increases greatly around the time that UI benefits lapse.

The share of U.S. workers in alternative work arrangements has increased substantially in recent decades. Micro longitudinal analyses show that unemployed workers are much more likely to transition into alternative work arrangements than other workers. Macro time-series evidence shows that weak labor market conditions lead to an increase in non-traditional work. But the estimated magnitudes imply that the Great Recession and high unemployment in the 2000s can account for only a modest part of the rise in alternative work. Secular factors associated with rising inequality and technological changes making it easier to contract out work appear to be the driving forces.

Pharmacy today is a highly remunerated female-majority profession with a small gender earnings gap and low earnings dispersion. Using extensive surveys of pharmacists, as well as the US Census, American Community Surveys, and Current Population Surveys, we explore the gender earnings gap, penalty to part-time work, demographics of pharmacists relative to other college graduates, and evolution of the profession during the last half-century. Technological changes increasing substitutability among pharmacists, growth of pharmacy employment in retail chains and hospitals, and related decline of independent pharmacies reduced the penalty to part-time work and contribute to the narrow gender earnings gap in pharmacy.

We provide theoretical and empirical analyses of an asymmetric-information model of layoffs. When firms have discretion with respect to whom to lay off, the market infers that laid-off workers are of low ability. Assuming that no such negative inference is warranted if workers are displaced in a plant closing, postdisplacement wages should be lower and postdisplacement unemployment spells should be longer for those displaced by layoffs than for those displaced by plant closings, but predisplacement wages should not differ by cause of displacement. Evidence on displaced workers from Current Population Surveys supports all three of our model's predictions.

This paper defines a concept, a worker's trust fund, which is useful in analyzing optimal age-earnings profiles. The trust fund represents what a worker loses if dismissed from a job for shirking. In considering whether to work or shirk, a worker weighs the potential loss due to forfeiture of the trust fund if caught shirking against the benefits from reduced effort. This concept is used to show that the implicit bonding in upward sloping age-earnings profiles is not a perfect substitute for an explicit up-front performance bond (or employment fee). It is also shown that the second-best optimal earnings profile in the absence of an up-front employment fee pays total compensation in excess of market clearing in a variety of stylized cases.

The fraction of U.S. college graduate women entering professional programs increased substantially just after 1970, and the age at first marriage among all U.S. college graduate women began to soar around the same year. We explore the relationship between these two changes and the diffusion of the birth control pill ("the pill") among young, unmarried college graduate women. Although the pill was approved in 1960 by the Food and Drug Administration and spread rapidly among married women, it did not diffuse among young, single women until the late 1960s after state law changes reduced the age of majority and extended "mature minor" decisions. We present both descriptive time series and formal econometric evidence that exploit cross-state and cross-cohort variation in pill availability to young, unmarried women, establishing the "power of the pill" in lowering the costs of long-duration professional education for women and raising the age at first marriage.

Recent work by David Lilien has argued that the positive correlation between the dispersion of employment growth rates across sectors (σ) and the unemployment rate implies that sectoral shifts in labor demand are responsible for a substantial fraction of cyclical variation in unemployment. This paper demonstrates that, under empirically satisfied conditions, traditional single-factor business-cycle models will produce a positive correlation between σ and the unemployment rate. Information on the job vacancy rate permits one to distinguish between a pure sectoral shift and a pure aggregate demand interpretation of this positive correlation. The finding that σ and the volume of help wanted advertising (a job vacancy proxy) are negatively related supports an aggregate demand interpretation.

The simplest economic theories of crime predict that profit-maximizing firms should follow strategies of minimal monitoring with large penalties for employee crime. We investigate possible reasons why firms actually spend considerable resources trying to detect employee malfeasance. We find that the most plausible explanations for firms' large outlays on monitoring of employees-legal restrictions on penalty clauses in contracts and the adverse impact of harsh punishment schemes on worker morale-are also consistent with the payment of premium (rent-generating) wages by cost-minimizing firms.
