A comparison of hazard rates of duration outcomes before and after policy changes is hampered by non-identification if there is unobserved heteogeneity in the effects and no model structure is imposed. We develop a discontinuity approach that overcomes this by exploiting variation in the moment...

This paper develops a tractable model for the computational and empirical analysis of infinite-horizon oligopoly dynamics. It features aggregate demand uncertainty, sunk entry costs, stochastic idiosyncratic technological progress, and irreversible exit. We develop an algorithm for computing a...

This paper develops an econometric model of firm entry, competition, and exit in dynamic oligopolistic markets. The model entertains market-level demand and cost shocks, sunk entry costs, and parameters that capture economic barriers to entry and the toughness of price competition. Nevertheless...

There is a tradition in the Netherlands to publish an annual ranking of economic and business researchers working in Dutch universities. The most recent such ranking, published in 2013, emphasizes research quantity over research quality. We propose an alternative ranking based on quality....

This paper empirically analyzes moral hazard in car insurance using a dynamic theory of an insuree's dynamic risk (ex ante moral hazard) and claim (ex post moral hazard) choices and Dutch longitudinal micro data. We use the theory to characterize the heterogeneous dynamic changes in incentives...

Part-time work whilst still in full-time education is common in many industrialized countries, and teenagers constitute a significant component of the work force in some sectors of the labour market. In Britain, in the early 1990's, some 60 percent of 16-18 year olds still in full time education...
