Owners of intellectual property or mere sponsors of an idea (e.g., authors, security issuers, sponsors of standards) often need to persuade potential buyers or adopters of the worth of their property or idea. To this purpose, they often resort to more or less independent certifiers. This paper...

We review the literature on sovereign debt. We organize our survey around three central questions: (1) Why do sovereign debtors ever repay their debts? (2) What burdens, in the form of distortions and inefficiencies, does sovereign debt impose? and (3) How might debt be restructured to reduce...

The majority shareholder in a closely held corporation may use its control of the corporate machinery to appropriate wealth from the minority, and it is difficult for the majority to make a binding commitment not to do so. This paper models the interaction between majority and minority...

Deferred Acceptance (DA), a widely implemented algorithm, is meant to improve allocations: under classical preferences, it induces preference-concordant rankings. However, recent evidence shows that—in both real, large-stakes applications and experiments—participants frequently play...

We show that inefficiencies from having separate markets to correct an environmental externality are significantly mitigated when firms participate in an integrated product market. Firms take into account the distribution of externality prices and reallocate output from markets with high prices...

Climate change is one of the major global challenges. Mitigating its impact is however bedeviled by free-rider problems and external effects. We thus study the problem of optimal carbon abatement in a dynamic non-cooperative game-theoretical setting involving multiple countries that are open...

Using an aggregative games approach, we analyze horizontal mergers in a model of multiproduct-firm price competition with nested CES or nested logit demands. We show that the Herfindahl index provides an adequate measure of the welfare distortions introduced by market power, and that the induced...

Two heterogeneous agents contribute over time to a joint project, and collectively decide its scope. A larger scope requires greater cumulative effort and delivers higher benefits upon completion. We show that the efficient agent prefers a smaller scope, and preferences are time-inconsistent: as...
