We examine peer effects in welfare use among immigrants to Sweden by exploiting a governmental refugee placement policy. We distinguish between the quantity of contacts—the number of individuals of the same ethnicity—and the quality of contacts – welfare use among members of the ethnic...

Most models of dynamic labor demand are written in terms of costs of adjusting employment (net adjustment costs). A few are based on the costs of hiring and firing (gross adjustment costs). This study derives several models containing both types of adjustment costs. A dynamic-programming model...

This study examines the nature of the costs that firms face in adjusting labor demand in response to shocks induced by changes in output demand and prices. Empirical work on monthly plant-level time-series data shows that adjustment proceeds in jumps. Employment is unchanged in response to small...

This paper studies the dynamics of labor demand at the plant and aggregate levels. The correlation of hours and employment growth is negative at the plant level and positive in aggregate time series. Further, hours and employment growth are about equally volatile at the plant level while hours...

Many kinds of economic behavior appear to be governed by discrete and occasional individual choices. Despite this, econometric partial adjustment models perform relatively well at the aggregate level. Analyzing the classic employment adjustment problem, we show how discrete and occasional...

Barnow, Trutko, and Piatak focus on whether persistent occupation-specific labor shortages might lead to inefficiencies in the U.S. economy. They describe why shortages arise, the difficulty in ascertaining that a shortage is present, and how to assess strategies to alleviate the shortage.
