On the invariance of the set of Core matchings with respect to preference profiles

We consider the general many-to-one matching model with ordinal preferences and give a procedure to partition the set of preference profiles into subsets with the property that all preference profiles in the same subset have the same Core. We also show how to identify a profile of (incomplete) binary relations containing the minimal information needed to generate as strict extensions all the (complete) preference profiles with the same Core. This is important for applications since it reduces the amount of information that agents have to reveal about their preference relations to centralized Core matching mechanisms; moreover, this reduction is maximal.     

Corporate responsibility and financial performance: the role of intangible resources

This paper examines the effects of a firm's intangible resources in mediating the relationship between corporate responsibility and financial performance. We hypothesize that previous empirical findings of a positive relationship between social and financial performance may be spurious because the researchers failed to account for the mediating effects of intangible resources. Our results indicate that there is no direct relationship between corporate responsibility and financial performance—merely an indirect relationship that relies on the mediating effect of a firm's intangible resources. We demonstrate our theoretical contention with the use of a database comprising 599 companies from 28 countries. Copyright © 2009 John Wiley & Sons, Ltd.     

Modern Perspectives on Fiscal Stabilization Policies

The present paper describes recent research on two central themesof Keynes' General Theory: (i) the social waste associated withrecessions, and (ii) the effectiveness of fiscal policy as astabilization tool. The paper also discusses some evidence onthe extent to which fiscal policy has been used as a stabilizingtool in industrial economies over the past two decades. (JELE32, E63)     

Upskilling y cambios distributivos en la cadena global de valor de la industria electrónica

La cadena global de valor de la industria electrónica es una de las más complejas de la economía internacional. Utilizando las tablas input‐output internacionales de 2000‐2014, se infieren las contribuciones individuales a dicha cadena para observar cómo la crisis de 2007–2008 afectó a su evolución y cartografiar las interacciones internacionales. Se observa un aumento de la deslocalización hasta el estallido de la crisis y después China y otras economías de Asia oriental se convierten en un epicentro de creación de valor. También se observa una profunda transformación de las tecnologías de producción, acompañada de un proceso de mejora del perfil de la cualificación (upskilling).     

Trade policy and wage gradients: evidence from a protectionist turn

In the spirit of Hanson (Econ J 107:113–133, 1997), we analyse, first, the existence of a relationship between the wage level and the market potential of Spanish regions; second, we explore the relative importance of domestic and foreign markets in this relationship; and finally, we examine the existence of a regional nominal wage gradient in Spain during the interwar period (1914–1930) centred on the main industrial cluster, Barcelona, and its transformation following the increase in protectionism in the Spanish economy as well as in the international economy. As suggested by NEG literature, our results support the hypothesis of a relationship between wages and regional market access and show the change in the regional wage structure following the gradual closing of the Spanish economy and of Spain’s trade partners, as a result of the increasing importance of the domestic market. We find evidence of the existence of a regional wage gradient centred on Barcelona which weakened during these years. Therefore, in Spain, during the interwar period, protectionist policies appear to have favoured the loss of centrality of a border region (Barcelona) and the relative rise of other locations.
