Population ecology models are elegant in form and adequate in describing aggregate data, but poor in telling stories and predicting the location of growth. Fundamentals models emphasizing the variables central to resource mobilization, such as intellectual human capital, can predict where and...

Faster technological progress has long been considered a key potential benefit of agglomeration. Physical proximity to others may help inventors adopt new ideas in their work by increasing awareness about which new ideas exist and by enhancing understanding of the properties and usefulness of...

We present a new methodology for ranking business schools. Unlike previous rankings based on subjective survey responses (from CEOs, business school deans, recruiters, or graduates), our approach uses data derived from the labor market for new MBAs. We adjust programs' salaries for the quality...

It is not surprising that the financing of early-stage creative projects and ventures is typically geographically localized since these types of funding decisions are usually predicated on personal relationships and due diligence requiring face-to-face interactions in response to high levels of...

We introduce an internal geography to the canonical model of international trade driven by comparative advantages to study the regional effects of external economic integration. The model features a dual-economy structure, in which locations near international gates specialize in export-oriented...

This paper reviews recent academic work on the spatial concentration of entrepreneurship and innovation in the United States. We discuss rationales for the agglomeration of these activities and the economic consequences of clusters. We identify and discuss policies that are being pursued in the...

What determines the distributions of skills, occupations, and industries across cities? We develop a theory to jointly address these fundamental questions about the spatial organization of economies. Our model incorporates a system of cities, their internal urban structures, and a...

We quantify the link between the timing of state-level implementations of political reservations for women in India with the role of women in India's manufacturing sector. While overall employment of women in manufacturing does not increase after the reforms, we find significant evidence that...

We show that isolated capital cities are robustly associated with greater levels of corruption across US states, in line with the view that this isolation reduces accountability, and in contrast with the alternative hypothesis that it might forestall political capture. We then provide direct...

Urban economies are often heavily reliant on a small number of dominant industries, leaving them vulnerable to negative industry-specific shocks. This paper analyzes the long-run impacts of one such event: the large, temporary, and industry-specific shock to the British cotton textile industry...
