This paper examines the supernatural punishment theory. The theory postulates that religion increases cooperation because religious people fear the retributions that may follow if they do not follow the rules and norms provided by the religion. We report results for a public goods experiment...

Does religion enhance prosocial behavior? We investigate the ways in which implicit influences of religious concepts affect generosity and cooperation. In contrast to previous studies, we assess the direct impact of religion as an independent variable on prosocial behavior. We do so by...

We investigate how implicit influences of Christian religious representations affect prosociality. We examine the direct impact of religion as an independent variable on prosocial behavior. We do so by priming participants with religious words in a scrambled sentence task before they make a...

This paper studies the evolutionary dynamics of migration. We argue that, under bounded rationality, the strategic foundations of the migrant behavior are based in the imitation of peers. We show that any migratory flow can be modeled from a dynamical system, whose parameters reflect the social...

This study analyzes technical change and efficiency level in the Colombian cement industry. We use the short-run production function approach in order to estimate efficiency measures and the main features of technical change. A time series covers the period between 1968 and 1988. The data base...

This paper compares the levels of technical efficiency reached by bus transport companies during the period 1989-1996, taking into account the deregulation context in which they operate. The empirical evidence reveals that there are no substantial changes in the use of inputs after the bus...

The aim of this study is to investigate the effect of privatisation on productivity development in the Chilean potable water and sewage sector. We have access to high quality firm level data making it possible to study the effects on a firm level. Productivity development is studied by means of...

This paper examines the supernatural punishment theory. The theory postulates that religion increases cooperation because religious people fear the retributions that may follow if they do not follow the rules and norms provided by the religion. We report results for a public goods experiment...

We study the relationship between trust in an experiment and trust measured by means of popular survey items in different countries. Students from Chile, Colombia, India, Mexico and Sweden participate in a public goods game experiment and answer a set of standard attitudinal survey questions...

In this work the evolutionary dynamics of migratory behavior driven by imitation is studied. We show that, any migratory flow, driven by the imitation, can be modeled by a dynamic system, once the rules governing imitative behavior of the population, are established. The parameters...
