In this paper we study the effects of the change in contract length on the agents' incentives to invest and exert effort. We present an agent's dynamic decision model that explicitly deals with two types of investments and directly allows for contract regime switching by varying the probability of...

In this paper we investigate the problem of nonparametric monotone frontier estimation from an extreme-values theory perspective. This allows to revisit the asymptotic theory of the popular Free Disposal Hull estimator in a general setup, to derive new and asymptotically Gaussian estimators and to...
