Curriculum Vitae

Working Papers

Affecting Distributions of Opinions with Evidence, with Isabel Melguizo-Lopez (January 2026)

How are communicators influenced by the available technology and by the initial opinions of their audiences when acquiring and disclosing evidence?

Persuasion under “Aspect-Restricted” Experimentation (January 2020)

How does committed experimentation on one aspect of a problem affect soft communication on another aspect?

Publications

Evidence Disclosure with Heterogeneous Priors, with Isabel Melguizo-Lopez
Mathematical Social Sciences, (2024), 132, 69-74

Can stringent regulations on evidence acquisition disincentivize the disclosure of evidence?

Making Friends: The Role of Assortative Interests and Capacity Constraints, with Isabel Melguizo-Lopez
Journal of Economic Behavior and Organization, (2022), 203, 431-465

If people make friends following assortative tastes but are capacity constrained, can combinations of homophilic and heterophilic friendship patterns arise? Are sizes of different groups important for the efficiency of stable friendship patterns

Discrimination through Versioning with Advertising in Social Networks
Economic Theory, 2019, 73:3, 525-564

What is the optimal pricing of platforms that sells premium and free versions of a service through a social network? Does the degree of the network influence the welfare implications?

Versioning and Advertising in Social Networks: Uniform Distributions of Valuations
Economics Bulletin, 2019, 39,1: 480-494

If consumers have uniform valuations, what are the profits of a platform that sells premium and free versions of a service through a social network?

On Information Aggregation and Interim Efficiency in Networks
Games, 2017, 8 (1), 15

If people listen to others’ opinions in a network, what is the welfare role of the network density?

Identifying Defectors in a Population with Short-Run Players, with Luciana Moscoso Boedo
Economics Bulletin, 2015, 35,2: 1392-1403

How is cooperation sustained with long-lived and short-lived agents if a mechanism identifies defectors?

A Model of Belief Influence in Large Social Networks
Economic Theory, 2015, 59: 21-59

If people act as Bayesian learners from others’ opinions through paths in a network, then entropy-based measures characterize long-term beliefs. Consensus is bolstered when there are prominent agents with limited influence

Information Acquisition Interactions in Two-Player Quadratic Games
International Journal of Game Theory, 2014, 43, 455-485

Are strategic motivations inherited from actions choices to information acquisition choices when only a small number of agents interact?

A Note on Bargaining over Complementary Pieces of Information in Networks, with Kaniska Dam
Economics Bulletin, 2012, 32, 4: 3098-3110

If people bargain on their information in star and line networks, then first-mover advantages are key to the agreed prices

Dividend Paying Assets, the Unit Root Property, and Suboptimality, with Subir K. Chattopadhyay
Journal of Mathematical Economics, 2009, 45, 3-4: 223-232

When do social security systems fail to ensure efficient allocations? With nonnegative dividends of long-lived assets, the Perron root of the matrix of rates of substitution informs about suboptimality.

A Model of Interim Information Sharing under Incomplete Information
International Journal of Game Theory, 2006, 34: 425-442

When two people exchange complementary pieces of information before competing, one wants to reveal less as the other reveals more

Notes on the Suboptimality Result by J. D. Geanakoplos and H. M. Polemarchakis (1986)
Estudios Economicos, 2007, 22, 1: 111-136

A pedagogical alternative proof of the cornerstone result on suboptimality under incomplete asset markets by Geaneakoplos and Polemarchakis (1986)
