I argue that academic research often inadequately accounts for alpha decay. As an anomaly's alpha (i.e., the risk-adjusted expected excess return) and realized returns are negatively related, alpha decay coincides with positive realized returns. If the alpha decays at publication, observers may...

We examine in this paper the training and test set performance of several equity factor models with a dataset of 20 years of data, 1,200 stocks and 100 factors. First, we examine several models to forecast expected returns, which can be used as baselines for more complex models: linear...

We use the tools of mechanism design, combined with the theory of risk measures, to analyze a model where a cash constrained owner of an asset with stochastic returns raises capital from a population of investors that di¤er in their risk aversion and budget constraints. The distribution of the...

This paper investigates to what extent low-income developing countries (LIDCs) characterized as frontier markets (FMs) have begun to be subject to capital flows dynamics typically associated with emerging markets (EMs). Using a sample of developing countries covering the period 2000-14, we show...

The concept of a market portfolio plays an important role in many financial theories and models. Knowledge of each asset's share of the invested capital markets is both useful information and a good starting point for investors considering the appropriate allocation to the asset. In our latest...

Experiments are an underused method in finance and have natural advantages for behavioral finance. Experiments can provide a useful means to circumvent several common econometric issues such as omitted variables, unobserved variables, and self-selection. Experiments can extend the theoretical...

The main aim of the thesis is to formulate a concept of liquidity risk and to incorporate liquidity risk in market risk measurement. We first review two types of liquidity risk and the relation between liquidity risk and market risk. To achieve our aim, we use a new framework of portfolio theory...
