This paper analyzes peer effects among university scientists. Specifically, it investigates whether the number of peers and their average quality affects the productivity of researchers in physics, chemistry, and mathematics. The usual endogeneity problems related to estimating peer effects are...

There has been a remarkable increase in wage inequality in the US, UK and many other countries over the past three decades. A significant part of this appears to be within observable groups (such as age-gender-skill cells). A generally untested implication of many theories rationalizing the...

Developing countries are vulnerable to the adverse effects of climate change, yet there is disagreement about what they should do to protect themselves from antic- ipated damages. In particular, it is unclear what the optimal balance is between investments in traditional productive capital...

In this paper we have built a model of financial intermediation that explains the GDP variability pattern of an economy during the development process. In our model, per capita is more volatile in the middle-income economies than in both low and high-income economies. We show that, if the model...

This paper presents a model of endogenous innovation and growth, in which technological change is path dependent. The historical pattern of technological development plays a central role in determining the pace of future technological change. Path dependence is explained using a distinction...

Growing cultural diversity is seen as important for innovation. Research has focused on two potential mechanisms: a firm effect, with diversity at the firm level improving knowledge sourcing or ideas generation, and a city effect, where diverse cities helping firms innovate. This paper uses a...

Empirical papers studying the effects of neighbourhood characteristics on socio-economic variables have predominantly used US data. We argue that the local nature of the US schooling system means that neighbourhood effects on education decisions may act through fiscal or social channels. We use...

This paper uses data on a sample of Australian teenagers to test for neighbourhood effects on school dropout rates. The data allows us to test for neighbourhood effects at two different spatial scales. We find that educational composition of the larger neighbourhood can influence the dropout...
