Horizontal innovation in the theory of growth and development

Gino Gancia () and Fabrizio Zilibotti ()

Economics Working Papers from Department of Economics and Business, Universitat Pompeu Fabra

Abstract: We analyze recent contributions to growth theory based on the model of expanding variety of Romer (1990). In the first part, we present different versions of the benchmark linear model with imperfect competition. These include the “labequipment” model, labor-for-intermediates” and “directed technical change”. We review applications of the expanding variety framework to the analysis of international technology diffusion, trade, cross-country productivity differences, financial development and fluctuations. In many such applications, a key role is played by complementarities in the process of innovation.

Keywords: appropriate technology; complementarity; cycles; convergence; directed technical change; endogenous growth; expanding variety; financial development; imperfect competition; integration; innovation (search for similar items in EconPapers)
