This paper analyzes the emerging literature on the determinants of giving within a social network. We propose two main explanatory variables for previous experimental results on the friendship effect. The first is social ...

This paper explores the role of social integration on altruistic behavior. To this aim, we develop a two-stage experimental protocol based on the classic Dictator Game. In the first stage, we ask a group of 77 undergraduate ...

This paper discusses the long run effect of changes in the age distribution of Spanish population on the unemployment rate, disaggregated by sex and age segments in the light of cointegration theory given the non stationarity ...

I analyze how changes in life expectancy affect retirement age, education time, and growth rates of economies. I set up a continuous time, overlapping generations model of endogenous growth with externalities in human ...

A disadvantage of multiple-choice tests is that students have incentives to guess. To discourage guessing, it is common to use scoring rules that either penalize wrong answers or reward omissions. These scoring rules are ...

It has been argued that terrorism should not have a large effect on economic activity, because terrorist attacks destroy only a small fraction of the stock of capital of a country (see, e.g., Becker and Murphy, 2001). In ...

A domestic exporting firm faces exchange rate uncertainty and has the option to install capacity abroad, thus becoming multinational. We analyze when the firm should exercise such an option optimally in the context of a ...

Building on Item Response Theory we introduce students’ optimal behavior in multiple-choice tests. Our simulations indicate that the optimal penalty is relatively high, because although correction for guessing discriminates ...

In this paper we study the effect of population age distribution upon private consumption expenditure in Spain from 1964 to 1997 using aggregate data. We obtain four main results. First, changes in the population pyramid ...

This paper analyzes the process of endogenous union formation in the context of a sequential bargaining model between a firm and several unions and tries to explain why workers may be represented by several unions of ...
