There is a substantial empirical literature quantifying the positive relationship between city size and productivity. The paper draws out the implications of this productivity relationship for evaluations of urban transport improvements. A theoretical model is developed and used to derive a...

We explore the association between urban density and pupil attainment using three cohorts of pupils in schooling in England. Although – as widely recognised – attainment in dense urban places is low on average, this is not because urban environments disadvantage pupils, but because the most...

This paper estimates individual wage equations in order to test two rival non-nested theories of economic agglomeration, namely New Economic Geography (NEG), as represented by the NEG wage equation and urban economic (UE) theory, in which wages relate to employment density. The paper makes an...

The Lisbon summit of the European Council in March 2000 declared the number of people living in poverty and social exclusion in the European Union to be unacceptable, and called for steps to tackle the issue, beginning with the setting of targets for particular indicators. The targets suggested...

We explore the association between urban density and pupil attainment using three cohorts of pupils in schooling in England. Although—as widely recognised—attainment in dense urban places is low on average, this is not because urban environments disadvantage pupils, but because the most...

This paper investigates the relationship between a CEO’s social network, firm identity, and firm performance. There are two competing theories that predict contradictory outcomes. Following social network theory, one would expect a positive relation between social networks and firm...

Tournaments are designed to enhance participants’ effort and productivity. However, ranking near the top may increase psychological pressure and reduce performance. We empirically study the impact of interim rank on performance using data from international diving tournaments. We find that...

Economists have a well-developed theory of value but the theory of why people hold the values they do is rudimentary at best. In spite of the fact that it is common to argue that values are important, most work on values is normative and the positive theory of values is relatively under-...

This paper examines the determinants of self-employment success for microcredit borrowers. Theories of social capital and neighbourhood effects are integrated in an attempt to account for earnings differentials amongst a unique sample of microfinance borrowers. The paper posits that social...

We present a theory of ethnic conflict in which coalitions formed along ethnic lines compete for the economy’s resources. The role of ethnicity is to enforce coalition membership: in ethnically homogeneous societies members of the losing coalition can defect to the winners at low cost, and...
