We provide a general characterization of the structure of rational expectations equilibria of any degree of revelation for pure exchange, sequential economies, with deffinitely many states of private information, an incomplete financial market and nominal assets. We estimate the dimension of the...

Societies provide institutions that are costly to use, but able to enforce long-run relationships. We study the optimal decision problem of using self-governance for risk sharing or governance through enforcement provided by these institutions. Third-party enforcement is modelled as a costly...

When people share risk in financial markets, intermediaries provide costly enforcement for most trades and, hence, are an integral part of financial marketsu0092 organization. We assess the degree of risk sharing that can be achieved through financial markets when enforcement is based on the...

Exchanges and other trading platforms are often vertically integrated to carry out trading, clearing and settlement as one operation. We show that such vertical silos can prevent efficiency gains from horizontal consolidation of trading and settlement platforms to be realized. Independent of the...

This paper considers the role of foreign investors in developed-country equity markets. It presents a quantitative model of trading that is built around two new assumptions: (i) both the foreign and domestic investor populations contain investors of different sophistication, and (ii) investor...

During the last decade, markets for covered warrants (bank-issued options) have flourished in Europe and Asia. In these markets, investors often face a choice between many instruments that differ only slightly from each other. Based on retail trades in call options on the German DAX index, this...

Rational expectations has been the dominant way to model expectations, but the literature has quickly moved to a more realistic assumption of boundedly rational learning where agents are assumed to use only a limited set of information to form their expectations. A standard assumption is that...

We develop a dynamic stochastic general equilibrium model with rational inattention by households and firms. Consumption responds slowly to interest rate changes because households decide to pay little attention to the real interest rate. Prices respond quickly to some shocks and slowly to other...

The paper analyzes how the removal of barriers to entry in banking affect loan competition, bank stability and economic welfare. We consider a model of spatial loan competition where a market that is served by less efficient banks is opened to entry by banks that are more efficient in screening...
