We investigate the sources of differences in school performance between students of different races by focusing on identity issues. We find that having a higher percentage of same-race friends has a positive effect of white teenagers’ test score while having a negative effect on blacks’ test...

Using the UK Fourth National Survey of Ethnic Minorities, we explore the determinants of religious identity for Muslims and non-Muslims. We find that Muslims integrate less and more slowly than non-Muslims. A Muslim born in the UK and having spent there more than 50 years shows a comparable...

We develop a model in which non-white individuals are defined with respect to their social environment (family, friends, neighbors) and their attachments to their culture of origin (religion, language), and in which jobs are mainly found through social networks. We find that, depending on how...

This examination of the role and potential for replication in economics points out the paucity of both pure replication - checking on others' published papers using their data - and scientific replication - using data representing different populations in one's own work or in a Comment. Several...

We analyze the impact of adolescents’ friendship relations in their final-year class of high school on subsequent labor market success. Based on a typology of network positions we locate each student within the social system of the school class as either: an isolate, a sycophant, a broker or a...

Driving forces behind the occurrence of either paradigm shifts in science, or the development of new orientations within science, are often linked to demands for an increased validity or reliability in knowledge production in science. With this as a starting point, I discuss parallels and...

Over the past decade there has been a decline in the fraction of papers in top economics journals written by economists from the highest-ranked economics departments. This paper documents this fact and uses additional data on publications and citations to assess various potential explanations....

While the strategy of measuring and quantifying has been extremely successful, and valuable in the progress of science, it does not follow that it is universally useful. We argue that attempts to measure corruption can be counterproductive in several different ways. Qualitative and action...

The article presents a model of social norm evolution, which suggests how the increase in optimal and actual first response times (FRT) of economics journals can be related. When the optimal FRT and the norm about how much time refereeing should take increase, it seems that the existence of a...

This paper provides an experimental test of a theory of endogenous network formation. A group of subjects face a decision problem under uncertainty. The subjects are endowed with a private information about the fundamentals of the problem, and they are supposed to make a decision one after the...
