We use a life cycle model of consumption and portfolio choice to study the effects of social security on the investment decisions of households for the European case. Our model is mainly based on the one developed by Cocco, Gomes, and Maenhout (2005). We extend it by unemployment risk using...

Evidence on the portfolio holdings and transaction patterns of households suggests that the burden of inflation is not evenly distributed. We build a monetary growth model consistent with key features of cross- sectional household data and use this framework to study the distributional impact of...

This paper suggests a solution to what has become known as the private equity premium puzzle (Moskowitz and Vissing-Jorgensen (2002)). We interpret occupational choice as a dynamic portfolio choice problem of a life-cycle investor facing a liquidity constraint and imperfect information about the...

This paper analyzes the relationship between bilateral trade flows, trade openness, and asset holdings in a three-country stochastic general equilibrium model. The threecountry model set-up enables me to disentangle and separate the effects bilateral trade flows and trade openness have on...

For market with an atomless continuum of assets, we formulate the intuitive idea of a well-diversified portfolio, and present a notion of exact arbitrage, strictly weaker than the more conventional notion of asymptotic arbitrage, and necessary and sufficient for the validity of an APT pricing...

We provide a detailed portfolio analysis for a financial market with an atomless continuum of assets. In the context of an exact arbitrage pricing theory (EAPT), we go beyond the characterization of the existence of important portfolios (normalized riskless, mean, cost, factor and mean-variance...

As in the case with perfect foresight, under conditions of uncertainty investors respond to changes in the assets' relative returns. An increase in the expected return of one asset here typically (if both assets are not perfectly correlated) induces a shift, but not a plunge toward that asset....

We develop a dual currency search model to study equilibrium currency exchange and the determination of nominal exchange rates. Agents hold portfolios consisting of two distinct currencies. We study equilibria in which the two currencies are identical and equilibria in which the two currencies...

An economy in which deposit-taking banks of a Diamond/ Dybvig style and an asset market coexist is modelled. Firstly, within this framework we characterize distinct financial systems depending on the fraction of households with direct investment opportunities that are less efficient than those...

In this paper we focus on the analysis of the effect of prediction and estimation risk on the loss distribution, risk measures and economic capital. When variables for the determination of probability of default and loss distribution have to be predicted because they are not available at the...
