This paper investigates whether the international globalization of financial markets allows for significant cross-country risk-sharing at the business cycle frequency. We find that cross-country risk-sharing is still limited and this is unlikely to be the result of financial frictions that limit...

We study the optimal monetary policy in a two-country open-economy model under two monetary arrangements: (a) multiple currencies controlled by independent policy-makers; (b) common currencies controlled by a centralized policy-maker. Our findings suggest that: (i) Monetary policy competition...

We study a labour market equilibrium model in which firms sign optimal long-term contracts with workers. Firms that are financially constrained offer an increasing wage profile: they pay lower wages today in exchange for higher future wages once they become unconstrained. Because constrained...

We develop a dynamic general equilibrium model with two-sided limited commitment to study how barriers to competition, such as restrictions to business start-up, affect the incentive to accumulate human capital. We show that a lack of contract enforceability amplifies the effect of barriers to...

The volatility of US business cycle has declined during the last two decades. During the same period the financial structure of firms has become more volatile. In this paper we develop a model in which financial factors play a key role in generating economic fluctuations. Innovations in...

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...

During the last three decades the stock of government debt has increased in most developed countries. During the same period inter- national capital markets have been liberalized. In this paper we de- velop a two-country political economy model with incomplete markets and endogenous government...
