Perhaps the longest-standing problem in the theory of two-sided markets is developing a general model of competition. We extend the monopoly techniques of Weyl (forthcoming) to develop a solution concept, Insulated Equilibrium, that makes such a model tractable. In Insulated Equilibrium each firm’s...

I build a simple dynamic model of the formation of an international social network of importers and exporters. Firms can only export into markets in which they have a contact. They acquire new contacts both at random, and via their network of existing contacts. This model can explain (i) the cross-...

The question of how to develop a relationship is central to business and management. This is especially true when the environment is characterized by informational asymmetries and subjectivity, as for example in management consulting. This paper presents a model of relationship building inspired by...

Although mutualisms are common in all ecological communities and have played key roles in the diversification of life, our current understanding of the evolution of cooperation applies mostly to social behavior within a species, while mutualism theory has lagged behind. A major question is whether...

International migration is certainly one of the most effective way to alleviate poverty at a global level. When a given host country allows more immigrants in, this creates costs and benefits for that particular country as well as a positive externality for all those who care about world poverty....

Marschak (1953) suggested that applied research should begin by determining the minimal set of assumptions and data needed to make a prediction of interest. Standard identification analyses correspond poorly to this search, as they have either stringent data (local average treatment effects/IV and...

Models with unobserved heterogeneity, hidden Markov chains, and many other econometric models are based on mixtures of distributions. It seems crucial to have a general approach to identify them nonparametrically. Yet the literature so far only contains isolated examples, applied to specific models...
