Issues discussed include the history and future of portfolio theory, the key inputs necessary to perform portfolio optimization, speci®c problems in applying portfolio theory to ®nancial institutions, and the methods for evaluating how well portfolios are managed.

But previous estimates of the optimal portfolio (1) assume expected returns constant and (2) are not set up to test the hypothesis of mean-variance optimization. We use maximum likelihood estimation ...

The slightly simplified version of the Eaton-Kortum (EK) model that we work with has C nations each of which is endowed with a single factor of production (labor) used to produce a continuum of goods under conditions of perfect competition and constant returns. The transport costs between a typical origin nation (nation-o) and a typical destination nation (nation-d) are assumed to be of the ice...

Stakeholders in the science system need to decide where to place their bets. Example questions include: Which areas of research should get more funding? Who should we hire? Which projects should we abandon and which new projects should we start? Making informed choices requires knowledge about these research options. Unfortunately, to date research portfolio options have not been defined in a c...
