I study the expenditures of the Comédie française from 1759 to 1793 and the company's debt from 1723 to 1793. Expenditures were well controlled and changes in venues account for their increase over time. The debt, however, was less controlled, because of the company's partnership structure and...

There are many evidences which prove that cartels’ price leads to an economic inefficiency, due to the reduced consumers welfare. Antitrust authorities have set up different ways to defeat and prevent collusive agreements, but as widely showed by the literature, deterring collusion may have...

We characterize Nash equilibria in multi-product markets in which producers commit to vectors of supply functions contingent on all prices. The framework accommodates (dis)economies of scope in production, and goods may be substitutes or complements in demand. We show that equilibrium...

We develop a tractable model of competitive price cycles where prices are chosen alternatingly and consumers have heterogenous information. The model yields sharp empirical predictions about price patterns, impact of captive consumers and pass-through. Using rich station-level price data from...

We study information design in a vertically differentiated market. Two firms offer products of ex-ante unknown qualities. A third party designs a system to publicly disclose information. More precise information guides consumers toward their preferred product but increases expected product...

This paper derives a closed-form expression linking aggregate markups on im- ported inputs to concentration in a model of firm-to-firm trade with two-sided market power. Our theory extends standard oligopoly insights in two dimensions. First, it reveals that markups increase with exporter...

We analyse UK markups and profit margins for the pandemic period and its aftermath using unconsolidated balance sheets of non-financial corporations for both listed and unlisted firms. The markup increases by 14.7% between 2014 and 2022, exceeding any previously documented growth rate for UK...

We present a simple model where, before competing in prices, firms announce which prices they intend to choose. Deviating from these announcements involves a cost. We show that sharing pricing intentions results in prices being set above their competitive levels. All equilibria result in prices...

I derive a model-based equation relating pass-through to buyer size and estimate it on the micro transaction level data for Colombia. I find that after an exchange rate shock, sellers connected to larger buyers face more moderate changes in their prices in the seller currency (i.e., lower...

A cationic reagent is an essential raw material in printing paper production. The market environment of the cationic reagent industry is influenced by the printing paper industry. Owing to the COVID-19 pandemic, the global expansion of remote work and home education has decreased the demand for...

We have built and investigated analytically and numerically a differential game model of Cournot oligopoly with consideration of pollution, network structure, and continuous updating. Up to this time, games with network structure and continuous updating were considered separately. We analyzed...

A major section of the existing literature on strategic trade policy, following a partial equilibrium framework, observed that imposition of tariff by the domestic country leads to a rise in their wage level. Analysis on the impact of strategic trade policy intervention (tariff) on wages and...

State governments provide grants to students to subsidize college attendance. In response, colleges can adjust their tuition, aid policies, and admission standards, affecting equilibrium enrollment and pass-through of aid to students. To quantify demand- and supply-side responses, I develop a...
