Our paper examines whether the well-documented failure of unsophisticated investors to rebalance their portfolios can help to explain the enormous counter-cyclical volatility of aggregate risk compensation in financial markets. To answer this question, we set up a model in which CRRA-utility...

Our paper investigates whether the valuation effect caused by a large risk premium and a low risk-free rate can help to explain the enormous US current account and trade deficit observed in the past decade. To answer this question, we set up an endowment growth model in which investors are...

This study proposes that heterogeneous household portfolio choices within a country and across countries offer an explanation for global imbalances. We construct a stochastic growth multi-country model in which heterogeneous agents face the following restrictions on asset trade. First, the...
