Seminario 19/6: Luis Aguiar (JRC) – Platforms, Promotion, and Product Discovery: Evidence from Spotify Playlists


Abstract: Digitization has vastly increased the amount of new music produced and, because of streaming, has raised the number of songs available directly to consumers. While enhanced availability has levelled the playing field between already-prominent and new artists, creators may now be highly dependent on platform decisions about which songs and artist to promote. With…

Seminario 19/3: Luís Corchón (Universidad Carlos III de Madrid) – Two remarks on consumer surplus


Abstract: In this paper we investigate the use of consumer surplus in monopoly when the consumption of the outside good cannot be smaller than a certain number and when the weights given in the social welfare function to consumers and the firm are different. We assume quasi-linear utility and constant returns to scale. We find…

Seminario 19/1: Alfonso Rosa García (UCAM) -Coopetition: a group contest with inversely proportional prize-sharing


Abstract A general finding in group contest is that there is an over-expenditure of effort, that is contests between groups generate very high individual efforts (and little free riding) compared to theoretical predictions. However, in the literature the way that the prize is shared ranges only between proportional sharing to egalitarian sharing. In many environments…

Seminario 18/16: Joan María Esteban (Instituto de Análisis Económico, Barcelona), Laura Mayoral and Debraj Ray – Income Inequality and Class Conflict


Abstract: This paper revisits the link between income inequality and social conflict. In spite of its plausibility such link is not finding any clear, strong empirical backing. We explore a particular variation around the basic rent-seeking model of conflict with the goal of obtaining predictions more aligned with evidence [see Esteban and Ray 2008, 2011…

Seminario 18/15: Juan L. Eugenio-Martin (ULPGC)-El análisis económico del impacto local del turismo: aplicaciones de econometría espacial


Abstract El desarrollo del sector turístico ha evidenciado su relevancia a nivel agregado en términos de valor añadido y empleo generado. Sin embargo, la mayoría de los proyectos y políticas turísticas parten de una iniciativa local.

Abstract This paper models the inbound tourism demand of Thailand by focusing on six major tourism markets, including China, Malaysia, South Korea, Japan, Russia, and India. Several economics variables widely used in the demand modeling literature were adopted.

Seminario 18/12: -Pedro Pintassilgo (UAlg)-International Fisheries Agreements: A Game Theoretical Approach


The management of fish stocks harvested by several countries is an important economic and political issue at the international level. It is estimated that the harvests of these fish stocks account for about one third of world marine harvests. The cooperative management of international shared fish stocks, through International Fisheries Agreements, has proven to be…

up arrow graphic

Abstract: This paper adds the standard input–output linkages into a multi-sector endogenous growth model to study the interaction effects between linkages and technology adoption for aggregate productivity and for income per capita. We show that the greater the intensity with which a good is used as input by other sectors, the smaller are the technology…

Seminario 18/7: CANCELADO HASTA NUEVA ORDEN Juan José Ganuza (UPF and Barcelona GSE) and Fernando Gómez (UPF)- Formal Contracts Without Courts. Scoring Suppliers to Build Trust

Formal contract

CANCELADO POR ENFERMEDAD DEL PONENTE. SE AVISARÁ CUANDO SE FIJE OTRA POSIBLE FECHA. ABSTRACT Relevant empirical findings point at the actual use of explicit (but imperfectly en- forceable) formal contracts by businesses alongside substantial informal dimensions in the relationship. In this paper we formally show the supporting role that formal contracts play for relational interactions. …

Seminario 18/04: Francisco Alcalá Agulló (Universidad de Murcia)- Growth Sustainability and the Quality Dimension of Consumption


Abstract Which are the factors affecting the long run sustainability of GDP growth? This paper discusses a potentially important one that has been disregarded so far: the shift in advanced economies from quantity to quality growth. First, the paper lays down a simple model introducing the quality dimension of consumption into the IPAT analytical framework….
