We conduct a meta-analysis of 1,973 estimates of stock price responses to shareholder activism reported in 67 primary studies. We document publication bias in the literature. Corrected activism effects range from 0% to 1.5%. Effects are stronger when shareholder rights are better protected and...

We examine the factors influencing published estimates of hedge fund performance. Using a sample of 1,019 intercept terms from regressions of hedge fund returns on risk factors (the alphas) collected from 74 studies, we document a strong downward trend in the reported alphas. The trend persists...

A prominent factor used in most models predicting stock returns is firm size. Yet no consensus has emerged on the magnitude and stability of the size premium, with some researchers even questioning the usefulness of the factor. To take stock of the voluminous academic literature on the size...

A key theoretical prediction in financial economics is that under risk neutrality and rational expectations a currency's forward rates should form unbiased predictors of future spot rates. Yet scores of empirical studies report negative slope coefficients from regressions of spot rates on...

Ethical investments have become increasingly popular over the past years. Ethical funds restrict their investment based on environmental, social and/or ethical criteria. Prior research on the performance of ethical versus non-ethical funds yields mixed results. This paper investigates the...

Measuring risk in the stock market context is one of the key challenges of modern finance. Despite of the substantial significance of the topic to investors and market regulators, there is a controversy over what risk factors should be used to price the assets or to determine the cost of...

The signaling hypothesis suggests that firms have incentives to underprice their initial public offerings (IPOs) to signal their quality to the outside investors and to issue seasoned equity (SEO) at more favorable terms. While the initial empirical evidence on the signaling hypothesis was weak,...

This paper provides evidence that intensified product market competition increases information asymmetry between corporate insiders and investors. I use volume and gains from insider trading as proxies for information asymmetry. I show that when a firm faces competitive threats insiders purchase...

A key theoretical prediction in financial economics is that under risk neutrality and rational expectations, a currency's forward rates should form unbiased predictors of future spot rates. Yet scores of empirical studies report negative slope coefficients from regressions of spot rates on...

This paper conjectures that insiders exploit their stock's mispricing after earnings announcements to make profitable trades. We design two sets of tests to provide evidence of insider trading on mispricing of their stock. First, insiders' purchases and sales are profitable both after positive...
