We study the aggregate and distributional impact of product market interventions and profit taxes using a model of firm dynamics, credit constraints and incomplete markets. A key ingredient of our model is that markups are endogenous so that the markup a producer charges depends on the amount of...

We ask: what are the most efficient means of redistribution in an unequal society? We answer this question by characterizing the optimal shape of non-linear income and wealth taxes in a dynamic general equilibrium model with uninsurable idiosyncratic risk. Our analysis reproduces the...

We use micro data from Orbis on firm level balance sheets and income statements to document that accounting returns for privately held businesses are dispersed, persistent, and negatively correlated with firm equity. We also show that firms experience large, fat-tailed, and partly transitory...

Canonical menu cost models, when parameterized to match the micro-price data, cannot reproduce the extent to which the fraction of price changes increases with inflation. They also predict implausibly large menu costs and misallocation in the presence of strategic complementarities. We resolve...
