Alpha, or outperformance of a benchmark, can be generated in many ways within a portfolio. It can be created by picking the top hedge fund managers, or by capturing the illiquidity premium via alternative assets. Venture capital is a major source of alpha for long-term investors. Alpha can also...

Presentation Slides for "Overconfidence, Arbitrage, and Equilibrium Asset Pricing" This paper offers a model in which asset prices reflect both covariance risk and misperceptions of firmsapos prospects, and in which arbitrageurs trade against mispricing. In equilibrium, expected returns are...

Using trading data from Finland and the US, I empirically show that investors tend to buy riskier stocks following realized losses. The measure of risk that the investors seem to pay attention to is the market beta of a stock. This behavior of buying higher beta stocks after a realized loss is...

We develop a structural econometric model to elicit household-specific expectations about future financial asset returns and risk attitudes by using data on observed portfolio holdings and self-assessed willingness to bear financial risk. Our framework assumes that household portfolios are...

We present a general equilibrium model in which heterogeneous investors choose among bonds, stocks, and an Index Fund holding the market portfolio. We show that, under standard assumptions, an equilibrium exists. We then derive predictions for equilibrium asset prices, investor behavior, and...

Institutional investors, such as pensions and insurers, are typically constrained to hold enough wealth to be able to make their contractually promised payments to fund beneficiaries. This creates an additional risk in the economy, namely the risk of funding shortfall. We seek to explore the...

Elementary portfolio theory implies that environmentalists optimally hold more shares of polluting firms than non-environmentalists, and that polluting firms attract more investment capital than otherwise identical non-polluting firms. These results reflect the demand to hedge against high...

When systematic risk is high, or the market crashes, most risk-averse investors choose to exit the market; however, there are some contrarian investors who opt to make investments. We model such contrarian behaviors by incorporating investors' expectations of government policies into the...

The equity risk premium (ERP) remains one of the most hotly contested ideas in finance. The disagreement, in practical and theoretical terms, centres on how best to measure the risk of an investment, how to convert this risk measure into an expected return that compensates the investor for...
