Lone Wolves in Competitive Equilibria

By: Ravi Jagadeesan, Scott Duke Kominers and Ross Rheingans-Yoo

This paper develops a class of equilibrium-independent predictions of competitive equilibrium with indivisibilities. Specifically, we prove an analogue of the “Lone Wolf Theorem” of classical matching theory, showing that when utility is perfectly transferable, any... View Details

Stability and Competitive Equilibrium in Trading Networks

By: John William Hatfield, Scott Duke Kominers, Alexandru Nichifor, Michael Ostrovsky and Alexander Westkamp

We introduce a model in which agents in a network can trade via bilateral contracts. We find that when continuous transfers are allowed and utilities are quasi-linear, the full substitutability of preferences is sufficient to guarantee the existence of stable outcomes... View Details

Multilateral Matching

By: John William Hatfield and Scott Duke Kominers

We introduce a matching model in which agents engage in joint ventures via multilateral contracts. This approach allows us to consider production complementarities previously outside the scope of matching theory. We show analogues of the first and second welfare... View Details

Chain Stability in Trading Networks

By: John William Hatfield, Scott Duke Kominers, Alexandru Nichifor, Michael Ostrovsky and Alexander Westkamp

We show that in general trading networks with bilateral contracts, a suitably adapted chain stability concept (Ostrovsky, 2008) is equivalent to stability (Hatfield and Kominers, 2012; Hatfield et al., 2013) if all agents' preferences are fully substitutable and... View Details

Price Competition under Multinomial Logit Demand Functions with Random Coefficients

In this paper, we postulate a general class of price competition models with Mixed Multinomial Logit demand functions under affine cost functions. We first characterize the equilibrium behavior of this class of models in the case where each product in the market is... View Details

Trading Networks with Frictions

By: Tamás Fleiner, Ravi Jagadeesan, Zsuzsanna Jankó and Alexander Teytelboym

We show how frictions and continuous transfers jointly affect equilibria in a model of matching in trading networks. Our model incorporates distortionary frictions such as transaction taxes and commissions. When contracts are fully substitutable for firms, competitive... View Details

Competition on Many Fronts: A Stackelberg Signaling Equilibrium

By: Jerry R. Green and Jean-Jacques Laffont

An economic agent, the incumbent, is operating in many environments at the same time. These may be locations, markets, or specific activities. He is informed of the particular conditions relevant to each situation. His action in each case is observable by another... View Details

Deposit Competition and Financial Fragility: Evidence from the U.S. Banking Sector

By: Mark Egan, Ali Hortaçsu and Gregor Matvos

We develop a structural empirical model of the US banking sector. Insured depositors and run-prone uninsured depositors choose between differentiated banks. Banks compete for deposits and endogenously default. The estimated demand for uninsured deposits declines with... View Details

Does Apple Anchor a Shopping Mall? The Effect of the Technology Stores on the Formation of Market Structure

By: Doug J. Chung, Kyoungwon Seo and Reo Song

This study examines the effect of technology stores—company-owned Apple and Microsoft retail stores—on mall configuration. We formulate a structural model that considers the endogenous location decisions of retail stores, taking into account both market characteristics... View Details

History-based versus Uniform Pricing in Growing and Declining Markets

By: Oz Shy, Rune Stenbacka and David Hao Zhang

We analyze the Markov Perfect Equilibria of an infinite-horizon overlapping generations model with consumer lock-in to compare the performance of history-based and uniform pricing in growing and declining markets. Under history-based pricing, firms charge higher prices... View Details

Competing Platforms

This paper focuses on platform-intermediated markets where there are a small number of firms on one side and analyzes the strategic competition among platforms to get the oligopolistic side on-board. Due to the prevalence of both same and cross-side externalities,... View Details

Platform Competition, Compatibility, and Social Efficiency

By: Ramon Casadesus-Masanell and Francisco Ruiz-Aliseda

Katz and Shapiro (1985) study systems compatibility in settings with one-sided plat- forms and direct network effects. We consider systems compatibility in settings with two-sided platforms and indirect network effects to develop an explanation why markets with... View Details

Anger and Regulation

By: Rafael Di Tella and Juan Dubra

We propose a model where voters experience an emotional cost when they observe a firm that has displayed insufficient concern for other people's welfare (altruism) in the process of making high profits. Even with few truly altruistic firms, an equilibrium may emerge... View Details
