We show that predictable covariances between means and variances of stock returns may have a first order effect on portfolio composition. In an international asset menu that includes both European and North American small capitalization equity indices, we find that a three-state, heteroskedastic...

We calculate the ex-post portfolio performance for an investor who diversifies among stocks, bonds, REITS and cash. Simulations are performed for two alternative asset allocation frameworks – classical and Bayesian - and for scenarios involving two different samples and six different...

We calculate optimal portfolio choices for a long-horizon, risk-averse European investor who diversifies among stocks, bonds, real estate, and cash, when excess asset returns are predictable. Simulations are performed for scenarios involving different risk aversion levels, horizons, and...

Small capitalization stocks are known to have asymmetric risk across bull and bear markets. This paper investigates how variance risk affects international equity diversification by examining the portfolio choice of a power utility investor confronted with an asset menu that includes (but is not...

Members of an occupational pension plan face the same industry shocks, since membership is based on employment industry. An occupational pension fund may therefore design portfolio composition so as to hedge members’ labour income shocks at the industry level. This paper quantifies differences...

Welfare gains to long-horizon investors may derive from time diversification that exploits non-zero intertemporal return correlations associated with predictable returns. Real estate may thus become more desirable if its returns are negatively serially correlated. While it could be important for...

Given a settled reduction in the present level of tax revenue, and by exploring a very large combinatorial space of tax structures, in this paper we employ a genetic algorithm in order to determine the ‘best’ structure of a real world personal income tax that allows for the maximization of...

As economic and financial integration between the US and the euro area is strong, assessing whether the recent US crisis may affect the process of real and nominal convergence within the euro area is important. The paper addresses this issue in the framework of a large-scale open economy...

The dramatic rise in the disability insurance (DI) roles in the last 20 years has been the subject of much controversy in both popular and academic circles. While, the relationship between DI and labor force participation has been the subject of a growing literature, the mechanism of this...

We analyze the monitoring role of occupational pension funds, the largest category of shareholders in the UK. Our hypothesis is that, unlike other financial institutions, occupational pension funds are expected to monitor companies in which they hold large stakes because of their objectives,...
