This paper shows conditions under which a marginally progressive income tax emerges as the outcome of political competition between two parties, when labor is elastically supplied and candidates are uncertain about voters' choice at election day. Assuming the elasticity of labor is decreasing on...

During the last decades, the relationship between economic growth and environmental quality has generated a strong controversy among environmental academicians. The main debate is focused on responding a specific and direct question: will the economic development intensify seriously the...

This paper provides empirical evidence of the role of spatial factors on the determination of inflation dynamics for a representative set of tradable commodities in Chile. We present a simple model that explains inflation divergence across regions in a monetary union with similar preferences as...

We discuss the implications of a Stackelberg sequence of play between a cartel and the fringe. We consider two different approaches to collusion: (i) one-stage static model and (ii) a multi-period oligopoly model. Our main result is that in the static model with quantity-setting firms a stable...

As many traditional tourist destinations have experienced a slow down in tourist arrivals and expenditure, Butler’s (1980) Tourist Area Life Cycle (TALC) model seems to attract new attention from tourist researchers. The TALC describes the evolution of a tourist area from its discovery to its...

Empirical studies such as Goyal, van der Leij and Moraga (2006) or Newman (2004) show that scientific collaboration networks present a highly unequal and hierarchical distribution of links. This implies that some researchers can be much more active and productive than others and, consequently,...

We use the concept of cartel stability defined by d'Aspremont et al. (1983) to obtain that the sequence of play between the cartel and the fringe affects cartel stability in a quantity-competition setting where firms tacitly collude. We also prove that an endogenous sequence of play between a...

This study addresses the question of why some countries import more R&D- intensive goods than others. Using a panel data set of 80 countries for the period 1970 to 1995, results indicate that domestic investment, FDI and the quality of intellectual property rights (IPR) systems positively affect...

It has been empirically shown that structural holes in social networks enable potential large benefits to those individuals who bridge them (Burt, 2004). The pioneering paper Goyal and Vega-Redondo (2007) offers a new incentives based explanation of this phenomenon. But the main equilibrium...

We present a model which allows us to show that even in a public university system where tuition and fees are fixed by the administration, a stratification of public universities according to the quality they offer and the quality of students they select, can be observed. This result is similar...
