The paper examines changes in wage and hour labor regulation between 1898 and 1938. Many see the 1905 Lochner Supreme Court decision striking down hours limits for men as the beginning of 30 years in which labor regulation was stymied by the doctrine of "freedom of contract." That issue played a...

This study test for effects of OSHA enforcement, using data on injuries and OSHA inspections for 6,842 manufacturing plants between 1979 and 1985. We use measures of general deterrence (expected inspections at plants like this one) and specific deterrence (actual inspections at this plant). Both...

This article surveys the theory of the public enforcement of law -- the use of public agents (inspectors, tax auditors, police, prosecutors) to detect and to sanction violators of legal rules. We first present the basic elements of the theory, focusing on the probability of imposition of...

This paper explores firms' response to regulatory enforcement. New Source Review, a provision of the Clean Air Act, imposes stringent emissions limitations on significantly modified older power plants. In 1999, the EPA sued owners of 46 plants for NSR violations. We study how electricity...

In recent decades, democratic countries have signed hundreds of international environmental agreements (IEAs). Most of these agreements, however, are weak: they generally do not include effective enforcement or monitoring mechanisms. This is a puzzle in standard economic models. To study this...

We estimate the impact of state-level "E-Verify" legislation that mandates employment eligibility verification for private-sector workers. We document declines in formal sector employment and employment turnover after mandate passage, with effects concentrated among those likeliest to be...

We examine the timing of firms' operations in a formal model of labor demand. Merging a variety of data sets from Portugal from 1995-2004, we describe temporal patterns of firms' demand for labor and estimate production-functions and relative labor-demand equations. The results demonstrate the...

Wage inequality does not fully capture differences in job quality. Jobs also differ along other key dimensions, including the prevalence of labor rights violations. We construct novel measures of labor violation rates using data from federal agencies. Within local industries over time, a 10%...

China's new Labor Contract Law took effect on January 2008 and required firms to give migrant workers written contracts, strengthened labor protections for workers and contained penalties for firms that did not follow the labor code. This paper uses survey data of migrant workers in the Pearl...

Using plant-level data from the Annual Survey of Industries (ASI) for the fiscal years from 1998-99 through 2007-08, this study provides plant-level cross-state/time-series evidence of the impact of employment protection legislation (EPL) on total factor productivity (TFP) and labor productivity...
