London is one of the world’s major cities, and one of its most diverse. London’s cultural diversity is widely seen as a social asset, but there is little hard evidence on its importance for the city’s businesses. Theory and evidence suggest various links between urban cultural diversity...

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...

Over the period since 1970, Britain has improved its relative productivity performance, but there remains a significant gap in market sector productivity between Britain and both Continental Europe and the United States. Much of the gap between Britain and Continental Europe is due to lower...

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...

We study substitutions between home and market production over long periods of time. We use the results to get predictions about long-run trends in aggregate market hours of work and about employment shifts across economic sectors, driven by uneven TFP growth in market and home production. The...

Many cultural products have the same nonrival nature as scientific knowledge. They therefore face identical difficulties in creation and dissemination. One traditional view says market failure is endemic: societies tolerate monopolistic inefficiency in intellectual property (IP) protection to...

Why is GDP growth so much more volatile in poor countries than in rich ones? We identify four possible reasons: (i) poor countries specialize in more volatile sectors; (ii) poor countries specialize in fewer sectors; (iii) poor countries experience more frequent and more severe aggregate shocks...

We study a multi-sector model of growth with differences in TFP growth rates across sectors and derive sufficient conditions for the coexistence of structural change, characterized by sectoral labor reallocation, and balanced aggregate growth. The conditions are weak restrictions on the utility...

Can the increasing significance of knowledge-products in national income - the growing weightless economy - influence economic development? Those technologies reduce ''distance'' between consumers and knowledge production. This paper analyzes a model embodying such a reduction. The model shows...
