It is generally understood that in situations of asymmetric information, the principal is better off committing to long term contracts than committing to short term contracts. The result holds true even when long term contracts are constrained to be renegotiation proof. The paper argues that the...

This paper analyzes the equilibrium dynamics of an endogenous growth model with physical and human capital in which leisure considerations have a direct effect on the utility function. Even in the absence of technological externalities our model may contain multiple balanced paths. These...

We consider the problem of a Central Bank that has some exchange rate goals. We compare "direct" Intervention through sale/purchase of reserves in the currency market with an alternative strategy of intervention with options. The intervention affects the currency markets because as a result of...

We consider a small open economy that produces and consumes two goods, one tradable and one not. Domestic residents combine their own income with credit obtained either abroad or at home to invest in capital production, which requires the tradable good. Capital investments in the tradable sector...

The main goal in this paper is to analyze an economic model of endogenous growth where human capital accumulation acts as the engine propelling economic activity. The added ingredient in our model is that agents derive utility from consumption and leisure, where leisure is defined as the amount...

I provide new results concerning dynamics for the Kiyotaki-Wright model (1989). I permit mixed strategies, but only those that restrict agents to play a unique strategy for each opportunity set. My results demonstrate the importance of examining stability in such models, because they show that...

For the problem of adjudicating conflicting claims, we study lower bounds on the awards of each agent. We propose extending a lower bound by performing the following operation: (i) for each problem, assign the lower bound and revise the problem accordingly; (ii) assign the bound of the revised...

Investment banks develop their own innovative derivatives to underwrite corporate issues but they cannot preclude other banks from imitating them. However, during the process of underwriting an innovator can learn more than its imitators about the potential clients. Moving first puts him ahead...

I study a game in which firms first bid on wildcat tracts and then time their drilling decisions. In an equilibrium bids are used as a coordination device: if player i bid low while player -i bid high, player i waits while player -i drills. This equilibrium is consistent with the empirical...

We consider a set-up in which a principal must decide whether or not to legalise a socially undesirable activity. The law is enforced by a monitor who may be bribed to conceal evidence of the offence and who may also engage in extortionary practices. The principal only declares the activity...
