Is There a Replication Crisis in Finance?

Several papers argue that financial economics faces a replication crisis because many studies cannot be replicated or are the result of multiple testing of too many factors. We develop and estimate a Bayesian model of factor replication that leads to different conclusions, including finding the majority of asset pricing factors can be replicated.

Limitation on Trader Fund Losses under the CARES Act of 2020

This paper provides a simple unifying framework for value and momentum effects in asset pricing based on the present value model. Backing out reliable expected returns from the present value model requires valuation ratios that adjust for expected future earnings growth. We show empirically that stock price momentum forecasts future growth, helps to improve value’s forecast for expected returns, and is drowned out when accounting for realized growth.

Game On: Social Networks and Markets

This paper studies how echo-chamber effects and fake news can lead to disagreement and misinformation with effects on investors’ portfolios and market prices. It presents a model how an investment idea can propagate through a social network, generating a trading frenzy with high turnover, a bubble in the price, and high price volatility. The paper also presents empirical evidence on the dramatic events related to the GameStop stock in January 2021 and discusses broader economic implications.

The COVID-19 pandemic and the responses to it by governments, central banks and consumers have unleashed both disinflationary and inflationary forces, but we do not know which forces will win over the longer term.

We discuss how an investment portfolio could dramatically reduce its carbon footprint, potentially even achieving a ‘net zero’ carbon footprint. We discuss the pros and cons of techniques to achieve carbon reduction goals, including security selection, shorting high carbon footprint companies, and trading instruments such as carbon offsets and carbon permits.
