When people share risk in financial markets, intermediaries provide costly enforcement for most trades and, hence, are an integral part of financial markets' organization. We assess the degree of risk sharing that can be achieved through financial markets when enforcement is based on the threat...

In this paper, we quantitatively analyze to what extent a benevolent government should issue debt in a model where households are subject to idiosyncratic productivity shocks, insurance markets are missing and borrowing is restricted. In this environment, issuing government bonds facilitates...

During the last two decades, the degree of openness of national financial systems has increased substantially. At the same time, asymmetries in information and other financial market frictions have remain prevalent. We study both empirically and theoretically the implications of the opening up...

A 2-country model with two groups of agents, workers and capitalists is presented in which economic integration results in an initial phase of catch-up, where the less industrialised country experiences the rise in both capital and labour income. Then, after a certain level of integration has...

This paper evaluates the consequences of the integration of international asset markets when goods markets are characterized by price rigidities. Using an open economy general equilibrium model with volatility in the money markets, we show that such an integration is not universally beneficial....

We develop a model of vertical pricing in which an original manufacturer sets wholesale prices in two markets integrated at the distributor level by parallel imports (PI). In this context we show that if competition policy requires uniform wholesale prices across locations it would push retail...

We consider the regulation of national firms in a common market. Regulators can influence the production of national firms but they incur in a positive cost of public funds. First, we show that market integration is welfare improving if and only if the efficiency gains compensate for the...

The competitive effect of international market integration in industries with imperfect competition is of great policy interest. This paper focuses on the link between monopolization and market segmentation. It presents a model of multi-market entry deterrence with or without market commitments....

Power market integration is analyzed in a two countries model with nationally regulated firms and costly public funds. If generation costs between the two countries are too similar negative business-stealing outweighs efficiency gains so that following integration welfare decreases in both...
