Several models posit a positive cross-sectional correlation between markups and firm size, which, among others, characterizes misallocation, factor shares, and gains from trade. Yet, taking labor market power into account in markup estimation, we show that larger firms have lower markups. This...

Several models posit a positive cross-sectional correlation between markups and firm size, which characterizes misallocation, factor shares, and gains from trade. Accounting for labor market power in markup estimation, we find instead that larger firms have lower product markups but higher wage...

In this paper I use the production function approach popularized by De Loecker et al. (2020) to analyze the evolution of market power in Slovakia and some of its micro and macro implications. In contrast to other studies, I calculate markups from both value added and sales and empirically test...

When deciding whether to introduce market competition into a regulated industry, a regulator faces an important tradeoff. Market-based prices can provide incentives to allocate resources more efficiently and reduce costs, but the presence of market power may lead to increased markups. We use a...

This paper analyzes the effects of mergers and acquisitions on the markups of non-merging rival firms across a broad set of industries. We exploit expert market definitions from the European Commission's merger decisions to identify relevant competitors in narrowly defined product markets....

Electricity markets are prone to the abuse of market power. Several US markets employ algorithms to monitor and mitigate market power abuse in real time. The performance of automated mitigation procedures is contingent on precise estimates of firms' marginal production costs. Currently, marginal...

I develop a general framework for markup and markdown estimation that allows for profit sharing along value chains without making assumptions on conduct between vertically related firms. I derive the conditions under which the markup and markdown estimates relate to the firms' equilibrium...

In this note, we investigate the causal link between market concentration and markups in a retail setting. We study the Washington retail cannabis industry, which features exogenous variation in market concentration that resulted from retail licenses being awarded via lotteries. We observe...

This paper examines the impact of trade liberalization on firms' product and labor market power. We estimate the prevalence and intensity of firm-level price-cost markups and either wage markups or wage markdowns. We take the dependence between these model-consistent measures of product and...
