Building on a framework of heterogeneous uncertainty across the population, this paper provides a unified theoretical explanation for several salient features of household investment behavior: First, a fraction of households will choose not to participate in the stock market, with poorer...

In order to explain cross-country differences in the effects of capital market liberalization, this paper proposes a model of international asset markets in which investors in different countries each face constraints on portfolio choice. The model demonstrates that liberalization, i.e. the...

We develop a two-country international asset pricing model in which investors are heterogeneous. Exchange rate dynamics give rise to a currency risk premium, uncovered interest parity is violated. Countries whose output growth is expected to be sufficient to satisfy growth in demand have high...

We develop a two-country international asset pricing model in which some investors face leverage constraints. In contrast to models with a single `world' bond, we show that tightening regulation can lead to the risk free interest rate rising. When demand for borrowing is high, a tightening of...

We develop a two-country asset pricing model to explain countries' heterogeneous exposure to global risks and how these affect currency risk premia. In the model we consider separately the valuation of countries' consumption baskets from their sharing of risk. A currency's risk depends not only...

A prominent approach to modelling ambiguity about stock return distribution is to assume that investors have multiple priors about the distribution and these priors are distributed according to a certain second-order distribution. Realistically, investors may also have multiple priors about the...
