We analyze the duration of patent examination at the European Patent Office (EPO). Our data contain variables that are correlates of the applicants’ and examiners’ assessments of a patent’s economic and technical relevance as well as ex post-application citation measures which indicate the...

In a non-stationary job search model we allow unemployed workers to have a permanent option to leave the labour force. Transitions into nonparticipation occur when reservation wages drop below the utility of being nonparticipant. Taking account of these transitions allows the identification of...

This paper studies the relation between macroeconomic fluctuations and corporate defaults while conditioning on industry affiliation and an extensive set of firm-specific factors. Using a multiperiod logit approach on a panel data set for all incorporated Swedish businesses over 1990-2002, we...

This paper investigates how a mandatory activation program in Denmark affects the job finding rate of unemployed workers. The activation program was introduced in an experimental setting where about half of the workers who became unemployed in the period from November 2005 to March 2006 were...

We evaluate the effect of active labour market programs on the duration of unemployment in a reward or punish system. In Switzerland, unemployment benefits are conditional upon program attendance after 7 months of unemployment duration. In the evaluation we allow for selectivity affecting the...

This Paper studies the wage effects of the use of alcohol and tobacco. The analysis based on a recent survey in the Netherlands shows that for males the use of tobacco has a negative wage effect of about 10% while the use of alcohol has a positive wage effect of about the same size. Smoking and...

We propose a new econometric estimation method for analysing the probability of leaving un-employment using uncompleted spells from repeated cross-section data, which can be especially useful when panel data are not available. The proposed method-of-moments-based estimator has two important...

This paper provides micro-econometric evidence on the effectiveness of Active Labor Market Policies (ALMP) in Poland. We sketch the theoretical framework of matching estimators as a substitute for randomization in labor market programs. Using retrospective data from the 18th wave of the Polish...

This Paper uses a unique dataset collected among inhabitants of Amsterdam, to study the dynamics in the consumption of cannabis and cocaine. If people start using these drugs they are most likely to do so at age 18-20 for cannabis and age 20-25 for cocaine. An analysis of the starting rates...

In this paper we use individual level data from the Australian National Drug Strategy Household Survey to study the relationship between initiation into cannabis use and educational attainment. Using instrumental variable estimation and bivariate duration analysis we find that those initiating...
