We analyze the effects of commodity taxation in markets where suppliers implement second-degree price discrimination schemes, such as offering different package sizes and quality-differentiated versions of the same product. In these markets, suppliers distort the quantity (or quality) intended...

Emerging tracking data allow precise predictions of individuals' reservation values. However, firms are reluctant to conspicuously implement personalized pricing because of concerns about consumer and regulatory reprisals. This paper proposes and applies a method which disguises personalized...

This paper investigates the impact of price transparency on equilibrium prices and fees by considering a policy change implemented by Airbnb that affected the transparency of cleaning fees for IP addresses from the European Union (EU). Using a difference-in-differences approach, we find a...

The emergence of so-called "decentralised finance" (DeFi) and a shadow financial system of cryptocurrency exchanges and stablecoin issuers raises the challenge of how to apply technology-neutral regulation so that similar risks are subject to the same rules. This paper makes the case for...

We develop a model of misinformation wherein users' decisions to verify and share news of unknown truthfulness interact with producers' choices to generate fake content as two sides of a market that balance to deliver an equilibrium prevalence and pass-through of fake news. We leverage the...

This paper develops a theory of oligopoly and markups in general equilibrium. Firms compete in a network of product market rivalries that emerges endogenously out of the characteristics of the products and services they supply. My model embeds a novel, highly tractable and scalable demand system...

Markets are reputed to be more flexible than other economic arrangements, though the meaning of flexibility remains vague. For orthodox economists, it has a narrow interpretation based on relative price movements within equilibrating markets, leading to allocative efficiency. For heterodox...

This paper studies how selling constraints, which refer to the inability of firms to attend to all the buyers who want to inspect their products, affect the equilibrium price and social welfare. We show that the price that maximizes social welfare is greater than the marginal cost. This is...

This paper characterizes the power dynamics of firms in both product and labor markets in Lithuania between 2004 and 2018. We first show that both markets are not perfectly competitive, as both price markups and wage markdowns are far from unitary and homogeneous. Interestingly, we unveil that...

We study a variation of the duopoly model by Kreps and Scheinkman (1983). Firms limited by their capacity of production engage in a two stage game. In the first stage they commit to levels of production not exceeding their capacities which are then made common knowledge. In the second stage...
