In many-to-many matching markets, various concepts have been introduced to analyze stability. Most of these concepts are not straightforward to interpret. For instance, stability blocks may make members of a blocking coalition worse off. This paper argues that the differences between stability...

Since 2021, Kalshi has operated as the only federally licensed prediction market in the United States. Using transaction-level data on over 300,000 contracts, we provide the first systematic evidence on its pricing. Kalshi's contract prices are informative and improve in accuracy as markets...

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...

In markets with budget-constrained buyers, competitive equilibria need not be efficient in the utilitarian sense, or maximise the seller's revenue. We consider a setting with multiple divisible goods. Competitive equilibrium outcomes, and only those, are constrained utilitarian efficient, a...

In many industries, platforms compete with incumbents that are open to all consumers, whereas platforms require user affiliation. Consequently, platforms face two layers of competition: for the market, to attract users, and in the market, to compete with incumbents. We develop a dynamic model...

Priority-based allocation often requires eliminating justified envy, making serial dictatorship (SD) the only non-wasteful direct mechanism with that property. However, SD's outcomes can conflict with the policymaker's objectives. We introduce visible fairness, a framework where fairness is...

We introduce the Jungle Edgeworth Box economy as an analytical framework to analyze bilateral conflict and examine the interplay between coercion and voluntary exchange. We characterize the set of equilibria in which no further coercion or voluntary exchange occurs. By assuming that coercion...

This document provides recommendations for the statistical recording of capacity allocation and balancing markets, which are crucial for addressing deviations between supply and demand in electricity markets. It also includes guidance on transactions related to the electricity congestion income...

I study tâtonnement processes in a matching market without transfers. In each period, schools set cutoffs, i.e. the preference ranks of the least preferred students they are willing to admit, and students accept their most preferred offers. Cutoffs are adjusted on the basis of demand-supply...

This paper examines the welfare implications of priority service in a frictional search environment with heterogeneous outside options. Priority search facilitates expedited matching with public options in the market by charging a service premium. Our main analysis demonstrates that a...

This article explores the impact of procedural information on the behavior of students under two school admission procedures commonly used in the US, the EU, and other jurisdictions: the Gale-Shapley mechanism and the Boston mechanism. In a lab experiment, I compare the impact of information...

We study a large market model of dynamic matching with no monetary transfers and a continuum of agents who have to be assigned items at each date. When the social planner can only elicit ordinal agents' preferences, we prove that under a mild regularity assumption, incentive compatible and...

Governments in low-income countries are increasingly integrating off-grid electricity provision into national electrification strategies, creating novel, decentralized markets for electricity. This paper studies a highly decentralized product that plays an important role in energy access: pay as...

Heterogeneous interconnections, which link regulated electricity markets to liberalised ones, are becoming increasingly important. Several such interconnections are set to be established in the near future especially between European and North African countries (e.g., Tunisia-Italy,...

In this paper, we conduct a large-scale field experiment to investigate the manipulability of prediction markets. The main experiment involves randomly shocking prices across 817 separate markets; we then collect hourly price data to examine whether the effects of these shocks persist over time....

As digital platforms continue to evolve, they facilitate the exchange of information and create opportunities for innovation-driven growth and introduce new challenges for enterprises navigating research and development-driven transformation. In the study, we used the Probit model, IV-Probit...

Banning money in markets for goods like education or health is a common policy to prevent unfair access by the wealthy. We investigate whether this policy is well-targeted for its intended goal. For this, we introduce a fairness criterion called discrimination-freeness which requires that goods...

We study markets in which potential buyers engage in costly search to find a good deal. Our novel solution concept for prices builds upon the idea that any movement in a firm's price is followed by an opportunity for its competitors to respond with special offers. This mechanism selects the...

Since 2021, Kalshi has operated as the only licensed prediction market in the United States. We show that Kalshi's contract prices are relatively accurate predictors of outcomes and their accuracy increases as markets come closer to closing. However, the prices also display a systematic...

We analyse the conditions for a particular type of mixed strategy profile to be an equilibrium in a specific buy and sell strategic market game à la Shapley and Shubik (1977), with two goods, using best responses of a player against random bids by the other players. We first identify a...
