This paper proposes an explanation for mixed evidence on the behaviors of markups. The key mechanism consists of two complementary channels of risk internalization that arise when firms face uninsurable business risks. One channel is based on passive risk consideration, through which firms raise...

In this paper, I explore the impact of per capita income and population size on markups and bilateral trade flows in a random search framework. The intuition is that, when a firm randomly meets a consumer, only that consumer's income matters to the firm's pricing strategy;the size of the...

How do firms adjust their output, inventories, employment and capital in response to demandsideshocks? To understand this, we estimate a reduced-form model using firm-level panel dataand we construct a theoretical model that can match the estimated impulse-response functions.A combination of...

Estimating markups has a long tradition in industrial organization and international trade. Economists and policy makers are interested in measuring the effect of various competition and trade policies on market power, typically measured by markups. The empirical methods that were developed in...

We document that variations in government purchases generate a rise in consumption, the real and the product wage, and a fall in the markup. This evidence is robust across alternative empirical methodologies used to identify innovations in government spending (structural VAR vs. narrative...
