This paper examines the causal impacts of reducing solid waste imports on water quality in China, which was the world's largest importer of waste until recently. We focus on the National Sword policy, introduced at the end of 2017, which abruptly banned the import of plastics, textiles, vanadium...

Often, a treatment and the outcome of interest are characterized by the moment they occur, and these moments are realizations of stochastic processes with dependent unobserved determinants. We develop a simple and intuitive method for inference on the treatment effect. The method can be...

This paper proposes a new econometric estimation method for analyzing the probability of leaving unemployment using uncompleted spells from repeated cross-section data, which can be especially useful when panel data are not available. The proposed method-ofmoments- based estimator has two...

This paper studies the effect of unemployment benefits on the unemployment and subsequent employment duration using individual data from the European Community Household Panel, for France, Germany, and the UK. The empirical analysis is based on a two-state mixed proportional hazard model...

This paper studies the evolution of job stability in West Germany. Using data from the German Socio-Economic Panel, we first show that the median elapsed tenure declined for men between 1984 and 1999. Second, estimating proportional Cox hazard models with competing risks and controls for stock...

It is often argued that the high level of welfare claims in Germany causes little incentive for workers with low productivity to seek for a job. We examine the influence of the ratio between estimated potential labor income and the welfare payment level on the probability of leaving social...

In Canada, a policy aiming at helping single parents on social assistance become self-reliant was implemented on an experimental basis. The Self-Sufficiency Entry Effects Demonstration randomly selected a sample of 4,134 single parents who had applied for welfare between January 1994 and March...

Based on theoretical models of job mobility this paper provides an empirical analysis of job durations in West Germany using information from two cohorts of new entrants to the labor force. We adopt an accelerated failure time model allowing for unobserved heterogeneity. Thereby we combine the...

This paper presents an analysis of the failure and completion rates of graduate students in economics at three universities in The Netherlands. We find that an indicator of the research productivity of the supervisor is an important determinant of the completion and dropout rates. However, this...

The U.S. labor market has been experiencing unprecedented high average unemployment duration. The shift in the unemployment duration distribution can be traced back to the early nineties. In this study, censored quantile regression methods are employed to analyze the changes in the US...
