Oligopoly and Oligopsony in International Trade. February, 2023
Revise and Resubmit at Canadian Journal of Economics
with Vladimir Tyazhelnikov
[Replication Package]
We study the effects of international trade on the oligopsony power of firms in input markets. We build a theoretical model of international trade in which firms are oligopolists in the market for final goods and oligopsonists in the market for inputs. Consistent with evidence from the literature, firms' markups over unit costs rise with the level of oligopsony power and of oligopoly power. While trade liberalization decreases market power in one market, it has the opposite effect in the other. In particular, international competition between oligopolists in final goods markets causes oligopsony power to increase and oligopoly power to decline. In a simulation, we show that the increase in oligopsony power can more than offset the reduction in oligopoly power, resulting in a net increase in markups over unit costs.

Pricing in Firm-to-Firm Trade. Evidence from a Danish Multinational. August, 2022
Revise and Resubmit at Review of World Economics
with Elena Mattana
[Online Appendix]
We study pricing decisions in firm-to-firm trade. Using novel detailed transaction-level data from a Danish multinational firm, we find a large degree of price dispersion across countries, customers, and, surprisingly, within the same customer. In fact, we find that transaction-specific characteristics are the most important factors in explaining price variation. The dispersion of prices within a customer relationship can be affected by the firm's price setting strategy. Our unique dataset allows us to examine the consequences of the introduction of price lists of recommended and minimum prices. We find that the prices charged converge towards the recommended price, and that price dispersion within a customer can decline if the price lists reduce the pricing range for the products bought by that customer.

Quality Misallocation, Trade, and Regulations. April 2022 (under review)
CESifo Working Paper No. 9041
with Ariel Weinberger
[Video (older version)] [CESifo]
This paper incorporates product standard regulations into a multi-country general equilibrium framework with firm heterogeneity and variable markups. We model regulations as a fixed cost that any firm selling to an economy must pay, consistent with stylized facts that we present. The fixed cost can improve allocative efficiency by reallocating production towards high-quality firms, who under-produce in the market allocation, and away from low-quality firms least able to bear compliance costs. Importantly, the fixed cost generates a positive externality on the rest of the world as it induces entry of high-quality firms, and it improves the terms of trade of the non-imposing countries. Because of this positive externality, given a level of market access, governments do not choose domestic standards efficiently. The result justifies international cooperation based on the fact that such cooperation can improve welfare. We estimate our model and apply its gravity formulation to quantify the global welfare consequences of altering regulatory policies, the extent of the positive externalities across countries, the effects of cooperation, and the comparison with further tariff liberalization.

Large Firms, Consumer Heterogeneity and the Rising Share of Profits. January 2022
Revise and Resubmit at American Economic Journal: Macroeconomics
NBER Working Paper No. 29646
with Robert C. Feenstra and Mingzhi Xu
[Video (older version)] [NBER]
We examine the relationship between large firms and the rising profit share in a model that features oligopolistic competition and consumer heterogeneity. Conditional on the sales distribution, the presence of consumer heterogeneity increases the profit share because it increases firm-level markups. Using data on purchases at the household-barcode level from Nielsen, we quantify the role of consumer heterogeneity, finding that the aggregate markup and the profit share are 8 and 3 percentage points larger than those predicted by a model of a representative consumer. Furthermore, we find that the profit share has been increasing over time and that firm targeting of consumer types plays a role in explaining this rise.
