In some practical applications of transition models there is a natural limit on the duration of some state. An important example is the Youth Training Scheme (YTS), which is normally limited to two years. The authors modify the usual competing risks model for this case and derive a diagnostic...

We present results from an experiment with multiple public goods, where each good produces benefits only if total contributions to it reach a minimum threshold. The experiment allows us to compare contributions in a benchmark treatment with a single public good and in treatments with more public...

We develop new methods for analyzing randomized experiments with noncompliance and, by extension, instrumental variable settings, when the often controversial, but key, exclusion restriction assumption is violated. We show how existing large-sample bounds on intention-to-treat effects for the...

The diffusion of temporary work agency (TWA) jobs has led to a harsh policy debate and ambiguous empirical evidence. Results for the USA, based on quasi-experimental evidence, suggest that a TWA assignment decreases the probability of finding a stable job, while results for Europe, based on the...

Just as poverty analysis has a central part in Development Economics, studies of fertility behaviour have an equally important standing in the Demography literature. Poverty and fertility are two important aspects of welfare that are closely related. In this paper we use unique longitudinal data...
