Markets are often seen as impersonal mechanisms of exchange, yet many real-world transactions are deeply social. This paper examines how prosocial motives interact with economic exchange and how this affects market outcomes. I study these questions in the context of street vending - a ubiquitous...

Heterogeneous search costs enable price discrimination, which I study in the canonical Wolinsky (1986) sequential search setting. Firms observe a public signal of a consumer's search cost before posting a personalized price. The welfare effects of search-cost-based price discrimination depend on...

Advances in data collection enable firms to use consumer information for personalized pricing. In Clavor'a Braulin's (2023) symmetric two-dimensional model, this reduces prices and profits, while partial privacy yields the highest profits. Extending the model to asymmetric firms and vertically...

This paper deals with the price discrimination issue when a producer applies one price to a buyer in one selling location and another at another selling location for the same product. The specific case under consideration is the consumption of copyrighted products in television broadcasts and...

We study a dynamic game in which a monopolistic seller sequentially discloses information about a binary state to a consumer through priced experiments. The consumer privately observes a binary signal which influences her willingness to pay for information. We show that if buyer types favor...

We study price discrimination by a monopolistic seller that endogenously produces a market segmentation at a cost, and question the efficiency of the production of market segmentations led by private incentives. We show that the efficient market segmentation gives all the gains in total surplus...

We separate the effects of market power and capacity constraints in transportation. A simple model shows imperfect competition - not capacity constraints - generates differential freight price changes across buyers following a demand shock. Consistent with this, difference-in-differences...

Consumer consent regulation is the cornerstone of modern data privacy regulation such as the European GDPR and the Californian CCPA. By ensuring that consumers can reject any harmful data collection, the regulation seems an effective tool for protecting consumers against price discrimination. By...

In an experiment on the large language model GPT-4o, a supplier always makes a higher profit if it replaces uniform contract terms with a set of terms between which the customer may choose. The extra profit results from price discrimination. There is a first order and a second order effect. The...

Poland disposes on a large stock of mostly aged private passenger cars. In contrast younger cars still play minor role in individual mobility. The contribution analyzes reasons of lagging modernization by focusing on new cars prices with respect to regional price discrimination. It finds in...

We study a hybrid marketplace where a vertically integrated platform competes with a seller in a horizontally differentiated downstream market. The platform has a data advantage and can price discriminate consumers, whereas the seller cannot. Our analysis shows that, by properly setting the...

Street vending is an important source of self-employment for the urban poor. I combine observational, survey, and experimental data from Delhi to study this market. Partnering with vendors to randomize prices and passersby they solicit, I find that even with identical goods, child vendors are...

We develop a model of spatial competition with two heterogeneous in their market access chains, choosing between third-degree price discrimination in their local markets (flexible pricing) and a unified chain-level price (uniform pricing). The markets are interconnected with each other via...

Deployment subsidies for nascent technologies have moved to the forefront of climate action, industrial policy, and geoeconomics. To limit the substantial fiscal costs of such programs, policymakers routinely employ subsidy schedules that are nonlinear in the quantity agents deploy. However,...

The liquefied natural gas (LNG) industry is characterized by systematic inter-regional price differentials, raising the question of whether sellers price discriminate. This paper measures market power in the LNG spot market and studies how market power influences pricing, trade and welfare. I...

We consider a duopoly model where firms can identify only a share of consumers, which is positively correlated with the consumer' preferences. Firms charge personalized prices to the consumers they can recognize and a uniform price to the rest of consumers. The firms' available information is...

This paper is devoted to the development of heuristics for the dynamic pricing problem. A discrete time model of dynamic pricing on the fixed time horizon is proposed. It is applicable to products that satisfy two properties: 1) product value expires at a certain predetermined date, and 2)...

We analyze a sample of consumer-electronics products sold by the US NewEgg online-retailer to study the impact of Price Matching Guarantees (PMGs) policies on prices. By applying aDifference-in-Differences approach,we find that prices of the policy-adopting retailer increase by 4.7% during the...

We investigate the welfare effects of third-degree price discrimination by a two-sided platform that enables interaction between buyers and sellers. Sellers are heterogenous with respect to their per-interaction benefit, and, under price discrimination, the platform can condition its fee on...
