Abstract: We uncover new dynamic patterns related to importers age and the macroeconomic environment that static models cannot explain. Our patterns are related to import switching, i.e., the simultaneous adding and dropping of intermediates at the firm level. Three facts stand out. First, switching is pervasive as 65% of firms do it and, at the…
Abstract Spanish GDP grew at an average rate of 3.5% per year during the expansion of 1995- 2007, above the EU average of 2.2%. However, this growth was based on factor accumulation rather than productivity gains. In particular, TFP fell at an annual rate of 0.7%, while it increased at 0.4% in the EU and…
ABSTRACT The growth of the mobile data services market is no longer dependent on push strategies from suppliers. On the contrary, demand is now driving the market to the extent that it will not be easy for mobile operating companies to cope up with the demand to come in the near future. Operators are forced…
Abstract This paper proposes a theory of media silence. The argument is that news organizations have the power to raise public concern and so affect the probability that there is ex-post verification of the true state of the world. Following the seminal article by Gentzkow and Shapiro (2006), we consider a newspaper that seeks to…
Abstract Following the ideas of the Tourism Area Life Cycle (TALC) theory, we propose a dynamic econometric model for tourism demand where the reputation effect (the effect of the lagged demand on the current tourism demand) is not constant, but dependent on congestion. We test the model using panel data from Spanish regions during the…
Abstract Siguiendo la metodología propuesta por Koopman, Wang y Wei (2014) y a partir del banco de datos generado en base a las tablas input-output internacionales de la World Input-Output Database (WIOD), el trabajo analiza la integración de la economía española y sus distintos sectores en las cadenas globales de valor (CGV) a lo largo…
Abstract Recent research in international trade simultaneously has developed along two branches. Empirical research measures plants’ productivity and shows that exporters are more productive than non-exporters. Theoretical research develops models of heterogeneous firms and shows that exporters are more efficient than non-exporters. We argue that there is a disconnect: the measure of firm productivity used…
Abstract According to the product life-cycle theory, new products are invented and developed in the advanced economies, from which they are initially exported. At a later stage, part or all of their production process moves to lower-wage countries. These dynamics lead to a continuous process of international relocation of production. In this paper, we use…
Abstract We study both theoretically and empirically the relationship between different types of corporate social responsibility (CSR) and a firm’s product quality. On the one hand, observable external CSR (e.g., a firm’s involvement in a social project) can be used as a signal to unobservable product quality. On the other hand, internal CSR (e.g., human…
Abstract Deseamos exponer mediante un breve recorrido a través de algunos trabajos en ese ámbito algunas de nuestras experiencias, carencias, aprendizajes y retos conseguidos o inconclusos. Es claro que el problema es multi,… multidimensional, multivariante, multicriterio. Expondremos como distintas cuestiones conceptuales marcan líneas metodológicas distintas pasando por el Análisis Multivariante, Análisis Envolvente de Datos y…
