We propose two distinct approaches to the measurement of industry upstreamness (or average distance from final use) and show that they yield an equivalent measure. Furthermore, we provide two additional interpretations of this measure, one of them related to the concept of forward linkages in...

Estimates for the US suggest that at least in some sectors productivity-enhancing reallocation is the dominant factor in accounting for productivity growth. An open question, particularly relevant for developing countries, is whether reallocation is always productivity enhancing. It may be that...

Large firms spawn spin-outs caused by innovations deemed unrelated to the firm's overall business. Small firms generate demand for specialized services that lower entry costs for others. We study the interplay of these two localized externalities and their impact on regional innovation. We...

We present a joint study of the US structural transformation (the decline of agriculture as the dominating sector) and regional convergence (of Southern to Northern average wages). We find that empirically most of the regional convergence is attributable to the structural transformation: the...

This paper investigates whether the effects, on registered manufacturing output, employment, entry and investment, of dismantling the 'license raj' - a system of central controls regulating entry and production activity in this sector - vary across Indian states with different labour market...

This paper analyses a model of economic development in which international inequalities in the location of industry and income are supported by the agglomeration of industry in a subset of countries. Economic development may not be a gradual process of convergence by all countries, but instead...

This paper investigates the impacts of progressive trade openness, technological externalities, and heterogeneity of individuals on the formation of entrepreneurship in a two-country occupation choice model. We show that trade opening gives rise to a non-monotonic process of international...

This paper describes the spread of industry from country to country as a region grows. All industrial sectors are initially agglomerated in one country, tied together by input-output links between firms. Growth expands industry more than other sectors, bidding up wages in the country in which...

We study the relationship between geography and growth. To do so, we first develop a dynamic spatial growth theory with realistic geography. We characterize the model and its balanced growth path and propose a methodology to analyze equilibria with different levels of migration frictions. We...

This paper examines the relationship between openness and within-country regional inequality across 28 countries over the period 1975-2005. In particular, it tests a) whether increases in trade lead to rising inequalities, b) whether these inequalities recede in time, and c) whether increases in...
