We model the opacity of over-the-counter (OTC) markets in a setup where agents share risks, but have incentives to default and their financial positions are not mutually observable. We show that there is "excess leverage" in that parties take on short OTC positions that lead to levels of default...

We model the opacity of over-the-counter (OTC) markets in a setup where agents share risks, but have incentives to default and their financial positions are not mutually observable. We show that this setup results in excess "leverage" in that parties take on short OTC positions that lead to...

We study two-period pure-exchange Capital Asset Pricing Model (CAPM) economies with incomplete financial markets and restricted participation. We characterize the optimal financial-market structure and the efficient innovations consisting of both the introduction of new assets and the...

Suppose risk-averse managers can hedge the aggregate component of their exposure to firm's cash flow risk by trading in financial markets, but cannot hedge their firm-specific exposure. This gives them incentives to pass up firm-specific projects in favor of standard projects that contain...

The opacity of over-the-counter (OTC) markets – in which a large number of financial products including credit derivatives trade – appears to have played a central role in the ongoing financial crisis. We model such OTC markets for risk-sharing in a general equilibrium setup where agents...

We study two-period pure-exchange Capital Asset Pricing Model (CAPM) economies with a given degree of incompleteness of financial markets and given degrees of restricted participation of agents in the markets.We characterize the optimal financial asset structure and the optimal composition of...
