We formulate and solve a costly multi-unit search problem for the optimal selling of a stock of goods. Our showcase application is an inventory liquidation problem with fixed holding costs, such as warehousing, salaries or floor planning. A seller faces a stream of buyers periodically arriving...

In 1979, the “Ley de Aviación Comercial” (Commercial Aviation Act) was passed in Chile. Its main goal was to improve the air transport by means of “Open Sky Policies”, competence (freedom of prices) and a progressive lesser intervention of the official authority. Since then an...

Why does an altruistically inclined player behave altruistically in some contexts and egoistically or spitefully in others? This article provides an economic explanation to this question. The basic argument is centered on the idea that social norms shape our preferences through a process of...

We explore the role of prominence in equilibrium pricing in markets where search is sequential and random. Our model key feature is that more prominent firms are more likely to be sampled first. In contrast to ordered-search models, we find that more prominent firms inherit larger but less...

We formulate and solve dynamic programming models extending search theory to (1) multiple indivisible units and (2) perfectly divisible assets. Buyers arrive seeking randomly many units at a random price in (1), or with a random limit order in (2). The seller can partially exercise orders -...

We explore strategic information transmission when there is noise at the observation stage, when an expert observes signals, before he advises a policymaker. That is, the expert might be inexpert. We account for the fact that his signals might be totally uninformative, which is commonly known by...

This article tests the existence of credit constraints on higher education access by estimating actual marginal returns in the context of unobserved heterogeneity. We estimate higher education returns for those who attend to it and compare them with those of individuals who are at the margin of...

Previous empirical works on municipal efficiency have mostly used cross-sectional data which makes it impossible to separate unobserved heterogeneity from inefficiency. Furthermore, they have also typically used a two stages approach which has been widely criticized as the assumptions made in...
