This paper analyses optimal irreversible investment policy when profits are subject to a multiplicative geometric Brownian motion shock. The marginal product of capital is increasing initially and decreasing thereafter. In the latter range, optimal policy is familiar: capacity is added gradually...

This paper analyzes the dynamics of cost efficiency scores in the Spanish banking industry during the period 1985-1995 and asks how such dynamics are influenced by specialization. Efficiency has been estimated through a nonparametric approach, and a model of distributions dynamics has been...

This paper is focused on an activity that has received little attention in the bankingliterature, namely the Off-Balance Sheet activities (OBS). After examining what is meant behind the name OBS activities, the fast growth these operations have shown over the period 1985-1995, and the main...
