This paper revisits the link between strategic trade policies and the mode of competition in the product market, emphasizing the emergence of a different mode of competition if only one of the two governments implements such a policy. We show that with an endogenous mode of competition and an...

Understanding the dynamics of inter-group cooperation in human adaptation has been the subject of recent empirical and theoretical studies in evolutionary anthropology, beginning to fill gaps in our knowledge of how interactions across political, economic and social domains can – and often do –...

Norms and institutions enable large-scale human cooperation by creating shared expectations and changing individuals’ incentives via monitoring or sanctioning. Like material technologies, these social technologies satisfy instrumental ends and solve difficult problems. However, the similarities and...

L’objet de notre recherche est d’étudier les défis persistants de la distribution d’eau dans un contexte où l’approvisionnement repose sur un réseau de microentrepreneurs (ME), souvent mal reconnus et non-protégés au niveau institutionnel, mais jouant un rôle essentiel au bien-être, voire à la...

We describe a formal model of norm psychology that can be applied to better understand norm change. The model integrates several proximate drivers of normative behavior: beliefs and preferences about a) material payoffs, b) personal norms, c) peer disapproval, d) conformity, and e) authority...

We formalize inter-sectoral knowledge diffusion in a standard fully endogenous Schumpeterian growth model. Each sector is simultaneously sending and receiving knowledge; thereby, to produce new knowledge, the research and development activity of each sector draws from a pool of knowledge which...

Scholars and civil society have argued that competition erodes supplier morality. This paper establishes a robust irrelevance result, whereby intense market competition does not crowd out consequentialist ethics; it thereby issues a strong warning against the wholesale moral condemnation of markets...

We introduce a model of (platform-mediated) many-to-many matching in which agents' preferences are both vertically and horizontally differentiated. We first show how the model can be used to derive the profit-maximizing matching plans under customized pricing. We then investigate the implications...

We develop a model of competition in prices and infrastructure among mobile network operators. Although consolidation increases market power, it can lead to more efficient data transmission due to economies of scale, which we derive from physical principles. After estimating our model with French...

Extremiles are a least squares alternative to quantiles, determined by probability-weighted moments rather than tail probabilities. They benefit from several interpretations and closed form expressions that are equivalent for continuous distributions, and they characterize a distribution just as...
