Using newly collected national and sub-national data and historical case studies, this paper argues that differences in innovative capacity, captured by the density of engineers at the dawn of the Second Industrial Revolution, are important to explaining present income differences, and, in...

Whether people of differing types can live happily together is one of the most important social and political questions concerning urban areas. From a variety of theoretical perspectives, such mixing seems extremely unlikely. While the theoretical result seems well supported in the context of...

This paper addresses two main questions: (a) Has European integration hindered the implementation of labour, financial and product market structural reforms? (b) Do the effects of these reforms vary more across sectors than across countries? Using more granular reform measures, longer time...

Beginning in the late 1970s, China's economy delivered the largest growth spurt in recorded history. Striking discontinuity between recent outcomes and the economic experience of the prior 200 years invites portrayal of recent events as a "China miracle" that requires neither economic nor...

This paper offers a thesis for why the US overtook the UK and other European countries in the 20th century in both aggregate and per capita GDP as a case study of recent models of endogenous growth, where "human capital" is the engine of growth. By human capital we mean an intangible asset, best...

Throughout the imperial era, defensive walls surrounded Chinese cities. Although most city walls have vanished, the cities have survived. We analyze a sample of nearly 300 prefectural-level cities in China, among which about half historically had city walls. We document that cities that had...

This paper establishes a simple theoretical framework which comprises key forces that shape the structure and interrelation of cities to study the interdependencies between urban evolution and the environment. We focus on the potential of the unfettered market forces to economize on emissions. A...

We construct an endogenous growth model that includes a cultural variable along the dimension of individualism-collectivism. The model predicts that more individualism leads to more innovation because of the social rewards associated with innovation in an individualist culture. This cultural...

We revisit the link between poverty, the middle class and institutional outcomes using a newly developed cross-country panel dataset containing detailed information on the distribution of income and expenditures. When the size of the middle class increases (measured as the proportion of people...

Many scholars have argued that once "basic needs" have been met, higher income is no longer associated with higher in subjective well-being. We assess the validity of this claim in comparisons of both rich and poor countries, and also of rich and poor people within a country. Analyzing multiple...
