We study a dynamical model of interconnected firms which allows for certain market imperfections and frictions, restricted here to be myopic price forecasts and slow adjustment of production. Whereas the standard rational equilibrium is still formally a stationary solution of the dynamics, we...

This note investigates the causes of the quality anomaly, which is one of the strongest and most scalable anomalies in equity markets. We explore two potential explanations. The "risk view", whereby investing in high quality firms is somehow riskier, so that the higher returns of a quality...

Due to non-linear transaction costs, the fi nancial performance of a trading strategy decreaseswith portfolio size. Using a dynamic trading model a la Garleanu and Pedersen (2013), wederive closed-form formulas for the performance-to-scale frontier reached by competitive tradersendowed with a...

We analyze firm-level analyst forecasts during the COVID crisis. First, we describe expectations dynamics about future corporate earnings. Downward revisions have been sharp, mostly focused on 2020, 2021 and 2022, but much less drastic than the lower bound estimated by Gormsen and Koijen (2020)....

We measure how shareholders value a firm's ethical actions via an experiment. Our findings are threefold. First, the "selfish investor hypothesis'' is strongly rejected. Participants are willing to pay $ .7 more for buying a share in a firm giving one more dollar per share to charities....

This paper develops a general equilibrium model of a productive economy with negative externalities. Investors are not willing to accept lower returns than their best investment alternatives and entrepreneurs maximize profits. If capital markets are subject to a search friction, an ESG fund can...

Since 2003, the French unemployment insurance system provides downside insurance to eligible unemployed workers who decide to start a business. We evaluate how this policy change affects entry into self-employment. The reform significantly increases firm creation without worsening the quality of...

This paper shows that collateral constraints restrict firm entry and post-entry growth, even in the long-run. We use French administrative data and exploit cross-sectional variation in local house-price appreciation as shocks to the value of collateral available to homeowners. We control for...
