In the past decades several features of U.S. unemployment dynamics have been investigated empirically. The original focus of research was on the duration of unemployment. In later studies the cyclicality of incidence and duration, compositional effects and duration dependence of the exit rate...

This paper analyzes the effect of unemployment insurance sanctions on the transition rate from unemployment to employment. Sanctions are punitive benefits reductions that are supposed to make recipients comply with cer­tain minimum requirements concerning search behavior. We use a unique set of...

H. Theil has made important contributions to the analysis of simultaneous-equations models. This paper gives an exposition of some closely related recent developments in microeconometrics, with a focus on efforts to develop robust methods for dynamic policy evaluation. We set the stage with a...

We study a mixed hitting-time (MHT) model that specifies durations as the first time a Lévy process— a continuous-time process with stationary and independent increments— crosses a heterogeneous threshold. Such models are of substantial interest because they can be reduced from...

This discussion paper has resulted in chapter 2 in: 'Losing Work, Moving On: International Perspectives On Worker Displacement', Peter J. Kuhn, Ed., 2002, W.E. Upjohn Institute for Employment Research, Kalamazoo, MI, ISBN 0-88099-234-4.

This paper exhibits dynamic features of insurance contracts in the empirical analysis of moral hazard. We first show that experience rating implies negative occurrence dependence under moral hazard: individual claim intensities decrease with the number of past claims. We then show that dynamic...

This paper considers the effects of a monopolist raising the cost of entry for potential competitors on Markov-perfect industry dynamics. All entrants serving the model industry incur sunk costs, which they partially recover when exiting. Empirically, the probability of exit declines with the...

Often, the moment of a treatment and the moment at which the outcome of interest occurs are realizations of stochastic processes with dependent unobserved determinants. Notably, both treatment and outcome are characterized by the moment they occur. We compare different methods of inference of...
