This paper takes into account adverse selection in the implementation of universal service obligations (USOs) for a network industry with no bypass. USOs are characterized by a coverage constraint imposed on the network’s owner. We develop fully the model for a welfare maximizing coverage...

We characterize the divergence between in informational and economic efficiency in a rational expectations competitive market with asymmetric information about the costs of production. We find that prices may contain too much or too little information with respect o incentive efficient...

This paper reconsiders the role of foreign investors in developed country equity markets. It presents a quantitative model of trading that is built around two new assumptions about investor sophistication: (i) both the foreign and domestic populations contain investors with superior information...

This paper analyses the effects of scope expansion on the core activity of banks and provides a rationale for their interest in offering a wider product range. We show that scope economies may stem from moral hazard in the core business, and argue that a cost of scope expansion might be the...

This paper offers and tests a theory of training whereby workers do not pay for general training they receive. The crucial ingredient in our model is that the current employer has superior information about the worker’s ability relative to other firms. This informational advantage gives the...

We consider a setting in which two potential merger partners each possess private information pertaining both to the profitability of the merged entity and to stand-alone profits, and investigate the extent to which this private information makes ex-post regret an unavoidable phenomenon in...

We examine the determinants of capital flows to four developing countries during the 1990s using an explicitly disequilibrium econometric framework in which the supply and demand for capital are not necessarily equal, and the actual amount of the flow is determined by the ‘short side’ of the...

We present a model with adverse selection where information sharing between lenders arises endogenously. Lenders' incentives to share information about borrowers are positively related to the mobility and heterogeneity of borrowers, to the size of the credit market and to advances in information...

In a Common Currency Area (CCA) the Common Central Bank sets a uniform rate of inflation across countries, taking into account the area’s economic conditions. Supposing that countries in recession favor a more expansionary policy than countries in expansion, a conflict of interest between...

This Paper studies a general equilibrium economy in which agents have the ability to invest in a risky technology. The investment risk cannot be fully insured with optimal contracts because shocks are private information. We show that the presence of investment risks leads to under-accumulation...
