More than 100 research teams (RTs) from around the world tested the same set of hypotheses on the same data. They worked independently and wrote an academic paper based on their findings. These reports were be evaluated by more than 30 distinguished academics whom we refer to as peer evaluators (PEs). Their feedback was be passed on to the RTs so that they can revise their papers. The project coordinators will study the #fincap results to learn about the scientific process. They have committed ex-ante to a meta-science analysis which was frozen before any instructions and data were given to the RTs and PEs. This frozen “pre-analysis plan” was uploaded to the Open Science Framework on Monday, 2021-01-11. The project will lead to a peer-reviewed academic publication at high level. [less ▲]

Do large credit risk shocks spill over to small businesses and affect their real economic activity? Using information on small business credit risk, we find that small businesses show increased default and bankruptcy rates following a shock to a customer industry. On an industry level, the shock to a customer industry is followed by a decrease in industry markups, disproportionate closure of firms, and cutbacks in inventories. Our analysis quantifies the elevated credit risk among small businesses and suggests a non-negligible 0.83% increase in expected losses on a diversified loan portfolio following a credit risk shock. This study provides banks and supervisors with greater clarity on timing and on the extent of elevated small business credit risk. It also allows them to assess the exposure of a bank portfolio to fluctuations in small business default rate. Such improved default prediction reduces credit rationing to the small business economy.

Skewness Risk Premium: Theory and Empirical Evidence

Using an equilibrium asset and option pricing model in a simple economy under jump diffusion, we show theoretically that the aggregated excess market returns can be predicted by the skewness risk premium, which is constructed to be the difference between the physical and the risk-neutral skewness. In an empirical application of the model using more than 20 years of data on S&P500 index options, we find that, in line with theory, risk-averse investors demand risk-compensation for holding stocks when the market skewness risk premium is high. However, when we characterize periods of high and low risk aversion, we show that in line with theory, the relationship only holds when risk aversion is high. In periods of low risk aversion, investors demand lower risk compensation, thus substantially weakening the skewness-risk-premium-return trade off. [less ▲]
