International financial integration helps to diversify risk but also may increase the transmission of crises across countries. We provide a quantitative analysis of this trade-off in a two-country general equilibrium model with endogenous portfolio choice and collateral constraints. Collateral...

We measure the amount of income insurance and cross-sectional consumption smoothing (lending and borrowing) achieved within subgroups of states, such as regions or clubs, e.g. the club of rich states. We find that there is as much income insurance between, as well as within, regions. By...

In this paper we argue that in realistically calibrated two period general equilibrium models with incomplete markets CAPM-pricing provides a good benchmark for equilibrium prices even when agents are not mean-variance optimizers and returns are not normally distributed. We numerically...

We develop a model of financially constrained arbitrage, and use it to study the dynamics of arbitrage capital, liquidity, and asset prices. Arbitrageurs exploit price discrepancies between assets traded in segmented markets, and in doing so provide liquidity to investors. A collateral...

We develop a method that allows one to compute incomplete-market equilibria routinely for Markovian equilibria (when they exist). The main difficulty to be overcome arises from the set of state variables. There are, of course, exogenous state variables driving the economy but, in an incomplete...

In this article, we show how to analyse analytically the equilibrium policies and prices in an economy with a stochastic investment opportunity set and incomplete financial markets, when agents have power utility over both intermediate consumption and terminal wealth, and face portfolio...

This paper documents how poorer and less educated US households hold a smaller fraction of foreign assets in their financial portfolio. This average home bias of the poor is partly due to a lower probability of participating in foreign asset markets, often attributed to fixed costs of market...

This paper analyzes the determinants of cross-border asset trade on cross-country data and a Swedish data set. We focus our analysis on the effect of the euro for the determinants of bond trade, equity and banking assets. With the help of a theoretical model, we attempt to disentangle the...

We use portfolio theory to quantify the efficiency of state-level sectoral patterns of production in the United States. On the basis of observed growth in sectoral value added output, we calculate for each state the efficient frontier for investments in the real economy, the efficient Sharpe...

We develop a model where wealthy investors have an incentive to become controlling shareholders because they can earn additional benefits by expropriating outside shareholders. As a consequence, in countries where minority investor rights are poorly protected, both domestic and foreign portfolio...
