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...

A number of authors have attemted to test whether the U.S. economy is in a determinate or an indeterminate equilibrium. We argue that to answer this question, one must be impose a priori restrictions on lag length that cannot be tested. We provide examples of two economic models. Model 1...

We study identiÞcation in a class of three-equation monetary models. We argue that these models are typically not identiÞed. For any given exactly identiffed model, we provide an algorithm that generates a class of equivalent models that have the same reduced form. We use our algorithm to...

In order to explain the joint fluctuations of output, inflation and the labor market, this paper first develops a general equilibrium model that integrates a theory of equilibrium unemployment into a monetary model with nominal price rigidities. Then, it estimates a set of structural parameters...

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...

This paper examine differences between risk-neutral and objective probability densities of future interest rates. The identification and quantification of these differences are important when risk-neutral densities (RNDs), such as option-implied RNDs, are used as indicators of actual beliefs of...

Standard economic models hold that exchange rates are influenced by fundamental variables such as relative money supplies, outputs, inflation rates and interest rates. Nonetheless, it has been well documented that such variables little help predict changes in floating exchange rates u0097 that...

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...

The paper proposes a multi-factor international asset pricing model in which the exchange rate is allowed to be co-determined by a risk factor imperfectly correlated to other priced risks in the economy. The significance of this factor can be established as long as one is able to observe a proxy...

The Lisbon strategy could reinvigorate Europeu0092s economy and boost employment. In 2000 the European leaders agreed to stimulate economic growth and employment and make Europeu0092s economy the most competitive in the world. If Europe would really reach the goals they set, Europeu0092s Gross...
