New articles published in Economic Geography, European Urban and Regional Studies

Since last summer I’ve been pretty focused on helping get the What Works Centre off the ground, so I’m posting these two articles rather late in the day.

The first is online at European Urban and Regional Studies. It’s my over-ambitious attempt to build a framework for thinking about the economic impacts of diversity in cities, drawing on my own work as well as the growing international literature. Specifically, I critique and try to move beyond Richard Florida’s thinking on these issues.

Here’s the abstract:

In recent years, most European countries have experienced substantial demographic changes and rising cultural diversity. Understanding the social and economic impacts of these shifts is a major challenge for policymakers. Richard Florida’s ideas have provided a popular – and pervasive – framework for doing so. This paper assess Florida’s legacy and sets out a ‘post-Florida’ framework for ‘technology, talent and tolerance’ research. The paper first traces the development of Florida’s ideas. ‘Florida 1.0’, encapsulated by the Three Ts framework, has performed badly in practice. There are problems in bringing causality to the fundamental relationships, and in consistently replicating the results in other countries. ‘Florida 2.0’, though suggests that Creative Class metrics have value as alternative measures of human capital. This create space for a post-Florida agenda based on economic micro-foundations. I argue that the growing body of ‘economics of diversity’ research meets these conditions, and review theory and empirics. Urban ‘diversity shocks’ shift the size and composition of populations and workforces, with impacts operating via labour markets, and through wider production and consumption networks. While short-term labour market effects are small, over time low-value industrial sectors may become migrant-dependent. Diversity may help raise productivity and wages through innovation, entrepreneurship, market access and trade channels. Bigger, more diverse cities help generate hybridised goods and services, but may also raise local costs through crowding. All of this presents new challenges for policymakers, who need to manage diversity’s net effects, and address both economic costs and benefits.

The second piece is out in Economic Geography, and is co-authored with Neil Lee. This is an empirical study testing links between firm-level demographics, innovation and entrepreneurship. We use a recent sample of London businesses, and uncover some small but robust diversity effects.

Here’s the abstract:

A growing body of research is making links between diversity and the economic performance of cities and regions. Most of the underlying mechanisms take place within firms, but only a handful of organization-level studies have been conducted. We contribute to this underexplored literature by using a unique sample of 7,600 firms to investigate links among cultural diversity, innovation, entrepreneurship, and sales strategies in London businesses between 2005 and 2007. London is one of the world’s major cities, with a rich cultural diversity that is widely seen as a social and economic asset. Our data allowed us to distinguish owner/partner and wider workforce characteristics, identify migrant/minority-headed firms, and differentiate firms along multiple dimensions. The results, which are robust to most challenges, suggest a small but significant “diversity bonus” for all types of London firms. First, companies with diverse management are more likely to introduce new product innovations than are those with homogeneous “top teams.” Second, diversity is particularly important for reaching international markets and serving London’s cosmopolitan population. Third, migrant status has positive links to entrepreneurship. Overall, the results provide some support for claims that diversity is an economic asset, as well as a social benefit.
