Seminario: Ricardo Flores-Fillol (URV) – Airline alliances and service quality

Convenient scheduling, characterized by adequate flight frequency, is the main quality attribute for airline services. However, the effect of airline alliances on this important dimension of service quality has received almost no attention in the literature. This paper fills this gap by providing such an analysis in a model where flight frequency affects schedule delay…

Rosa Ferrer (UPF) – Consumers’ costly response to product-harm crises

Using an ideal setting from a major food safety crisis, we estimate a full demand model for the unsafe product and its substitutes and recover consumers’ preference parameters. Counterfactual exercises quantify the relevance of different mechanisms –changes in safety perceptions, idiosyncratic tastes, nutritional characteristics, and prices–driving consumers’ response. We find that consumers’ reaction is limited…

Seminario 18/02: Jordi Massó (Universitat Autónoma de Barcelona) – Not all majority-based social choice functions are obviously strategy-proof

Abstract We consider two families of strategy-proof social choice functions based on the majority principle: extended majority voting rules on the universal domain of preferences over two alternatives and generalized median voter schemes on the domain of single-peaked preferences over a finite and linearly ordered set of alternatives. We characterize their respective subclasses of obviously…
