Dynamic Labor Demand and Adjustment Costs


Book Description

Comprises a collection of essays by various authors on the subject of labour demand and adjusted labour costs which were previously published between 1962 and 1990.







Dynamic Labor Demand with Lumpy and Kinked Adjustment Costs


Book Description

We analyze the dynamics of firms' employment decisions which underlie lumpy and kinked adjustment costs. We consider a dynamic structural model in which, in each period, firms face a choice of whether to vary the labor input or to postpone the adjustment to the future. By exploiting the first order condition for optimality, we derive a semi-reduced form in which firms' intertemporal employment are defined by a standard static marginal productivity condition augmented by a forward-looking term. In this way we obtain a marginal productivity equilibrium relation which takes into account the future alternatives of adjustment or non-adjustment that firms face as the result of the presence of fixed and linear adjustment costs. Linear costs amount to 35% of average labor costs, and fixed costs are estimated to be about 3.65 times average unit labor costs.




Labor Demand


Book Description

In this book Daniel Hamermesh provides the first comprehensive picture of the disparate field of labor demand. The author reviews both the static and dynamic theories of labor demand, and provides evaluative summaries of the available empirical research in these two subject areas. Moreover, he uses both theory and evidence to establish a generalized framework for analyzing the impact of policies such as minimum wages, payroll taxes, job- security measures, unemployment insurance, and others. Covering every aspect of labor demand, this book uses material from a wide range of countries.







A Genral Model of Dynamic Labor Demand


Book Description

This study derives and estimates a dynamic model of factor demand that includes both fixed and quadratic variable costs of adjustment. Using quarterly data on the employment of mechanics at seven airlines, it finds that both types of adjustment costs characterize the dynamic constraints facing employers. Using monthly data covering production-worker employment in seven manufacturing plants, it shows that only fixed costs are important. The apparent diversity of the underlying costs of adjustment means it is difficult to draw useful inferences from macroeconometric estimates. It suggests the importance of examining broader arrays of microeconomic time series describing labor demand.










Demand for Labor


Book Description

The book collects articles published by Daniel Hamermesh between 1969 and 2013 dealing with the general topic of the demand for labor. The first section presents empirical studies of basic issues in labor demand, including the extent to which different types of labor are substitutes, how firms' and workers' investments affect labor turnover, and how costs of adjusting employment affect the dynamics of employment and patterns of labor turnover. The second section examines the impacts of various labor-market policies, including minimum wages, penalty pay for using overtime hours or hours worked on weekends or nights, severance pay for displaced workers, and payroll taxes to finance unemployment insurance benefits. The final section deals with general questions of discrimination by employers along various dimensions, including looks, gender and ethnicity, in all cases focusing on the process of discrimination and the behavior that results. Throughout the focus is on the development of theoretically-based hypotheses and testing them using the most appropriate data, often data collected uniquely for the particular project.
