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...

The basic paradigm of asset pricing is in vibrant flux. The purely rational approach is being subsumed by a broader approach based upon the psychology of investors. In this approach, security expected returns are determined by both risk and misvaluation. This survey sketches a framework for...

We examine how third party ratings and mandatory benchmark disclosure affect aggregate risk adjustment by retail investors. Morningstar changed its ratings methodology in June 2002. Before the change, the ratings were based on a risk-adjusted performance ranking of all US equity funds and highly...

This stochastic simulation analysis examines the risk characteristics of target-date funds focusing on the trade-offs between wealth creation and security. The dynamic portfolio adjustment of marketed target-date funds, with varied asset allocations, along age and various time horizons is shown....

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...

Individuals' stock market participation depends on the risk–return trade-off they expect to achieve from investing. We argue that the expected economic benefits from investing are highly heterogeneous. To capture these benefits, we define the personal equity risk premium (PERP) as the...

This paper analyzes how individuals value the two main payout options of retirement wealth accrued in a pension plan: a lifelong income stream offered via an annuity or as a lumpsum. A better knowledge of the drivers behind the financial valuation of pension options contributes to the...

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...

The salience theory perspective on asset prices implies that investors overvalue stocks with salient upsides and undervaluing firms with salient downsides. The resulting mispricing is subsequently reverted, producing a predictable pattern in the cross-section of returns. This study is the first...

I study the effects of risk and ambiguity (Knightian uncertainty) on optimal portfolios and equilibrium asset prices when investors receive information that is difficult to link to fundamentals. I show that the desire of investors to hedge ambiguity leads to portfolio inertia and excess...
