We find similar results at the industry level: industries with falling growth rates see more left-skewed growth rates of firm sales, employment, and productivity. We then build a heterogeneous-agent model in which entrepreneurs face shocks with time-varying skewness that matches the firm-level distributions we document for the United States. Our quantitative results show that a negative shock to the skewness of firms’ productivity growth (keeping the m...
