We develop a model where, in the first stage, minority individuals have to decide whether or not they want to assimilate to the majority culture while, in the second stage, all individuals (both from the majority and the minority group) embedded in a network have to decide how much effort they...

This paper analyses the influence of country-level education mismatch on the individual-level relationship between education and the probability of being unemployed or staying in alternative labour statuses, for young people aged 15-34 in 2006, 2008 and 2010, living in 21 EU countries. We assume...

We propose a random network model incorporating heterogeneity of agents and a continuous notion of homophily. Unlike the vast majority of the corresponding economic literature, we capture homophily in terms of similarity rather than equality by assuming that the probability of linkage between...

The intention of the Global Burden of Disease Study 2010 is to inform and to provide guidance to some public policies. This Working Paper points out some shortcomings of the Study, both as to method and as to usefulness for national policies, by means of a critique of the formation of the...

Problems of collective action are at the roots of several public policies and, as shown in this text, there are many mechanisms and tools to be used in order to solve those problems. Although three groups of mechanisms and tools have not been stressed in the usual debates of public policy, they...

The problem of coordination concerns how to make actions or choices of social agents (individuals or organizations) match in the right way. Some problems of coordination are also problems of separation. In many cases of lack of coordination, communication is faulty or not very reliable....

Understanding the effects of reciprocity on tax morale is crucial to explain tax compliance behavior. However, there is only little research about which sources of reciprocity affect tax morale most. Thus, this paper for the first time gauges the effects from two sources of reciprocity on tax...

This research establishes that the emergence, prevalence, recurrence, and severity of intrastate conflicts in the modern era reflect the long shadow of prehistory. Exploiting variations across national populations, it demonstrates that genetic diversity, as determined predominantly during the...

We investigate whether the field of study influences university students’ political attitudes. To disentangle self-selection from learning effects, we first investigate whether the fields of study chosen by the incoming students correlate with their political attitudes. In a second step we...

This paper is the first to estimate a causal effect of immigrant students’ reading performance on their math performance. To overcome endogeneity issues due to unobserved ability, we apply an IV approach exploiting variation in age-at-arrival and the linguistic distance between origin and...
