We develop a model with a finite number of multi-product firms that populate an industry together with a continuum of single product firms, and study the dynamics of this industry that arises from investments in the invention of new products. Consistent with the available evidence, the model...

In this paper I use data from a survey of firms to estimate the effects of a firm's wage level on several measures of its hiring costs and the characteristics and performance of its employees. These measures include the previous experience and current tenure of its employees; subjective...

Italy and Germany have similar geographical differences in productivity - North more productive than South in Italy; West more productive than East in Germany - but have adopted different models of wage bargaining. Italy sets wages based on nationwide contracts that allow for limited local wage...

This paper examines the macroeconomic aftermath of the 1992 breakdown of the European Exchange Rate Mechanism (ERM). The economic performance of six leaver' nations is compared with five stayer' nations that maintained a roughly fixed parity with the Deutsche Mark. Recent writing about...

This study develops alternative quarterly measures of labor costs that refine the published data on hourly earnings and hourly compensation for the period 1953-1978. These new series account for deviations of hours paid for from hours worked, for the tax treatment of wages under the corporate...

This study is a theoretical and empirical analysis of the effects of time and money costs of labor market participation on married women's supply behavior. The existence of fixed costs implies that individuals are not willing to work less than some minimum number of hours, termed reservation...

Digital versions of labor and capital can be reproduced much more cheaply than their traditional forms. This increases the supply and reduces the marginal cost of both labor and capital. What then, if anything, is becoming scarcer? We posit a third factor, 'genius', that cannot be duplicated by...

This paper measures the unemployment gap (the difference between actual and efficient unemployment rates) using the Beveridge curve (the negative relationship between unemployment and job vacancies). We express the unemployment gap as a function of current unemployment and vacancy rates, and...

Penology in the Jim Crow South centered on the chain gang. Gangs ostensibly served three purposes: their severity served as a deterrent; their putting convicts to work on roads and other public improvements reduced the taxpayers' costs of infrastructure; and their discriminatory implementation...

This paper explores the combined effects of reductions in trade frictions, tariffs, and firing costs on firm dynamics, job turnover, and wage distributions. It uses establishment-level data from Colombia to estimate an open economy dynamic model that links trade to job flows in a new way. The...
