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...

However, it is still unclear whether changes in the structure of the marriage pool or changes in the fitness-relevant...

We study how workers’ concern for coworkers’ ability (CfCA) affects competition in the labor market. Two firms offer nonlinear contracts to a unit mass of prospective workers. Firms may differ in their marginal productivity, while workers are heterogeneous in their ability (high or low) and their...

We review a tractable model of human capital investments that can accommodate lots of heterogeneity and we investigate its compatibility with some job search and equilibrium wage models that have been proposed in the literature. We show that the log wage equation derived from the combination of...
