Capital, Technology, and Economic Performance
Across economic doctrines of all stripes, one of the eternal verities is that capital plays a crucial role in determining the path and rate of growth in advanced economies. Contemporary work in geography, regional economics, and planning has reinforced this view, attesting to the key influence of investment—and investors—on the economic vitality of localities and regions. However, until comparatively recently, both our theoretical apparatus for understanding the role of capital in regional development and our collected body of empirical evidence to illuminate this process were rather limited (Gertler 1984b; 1987). Our understanding of the investment process has developed along new lines of theoretical inquiry only since the mid-1980s. At the macroeconomic scale, economists have attacked the study of growth theory with renewed vigour, in an attempt to incorporate some of the most important attributes of the capitalist system—such as technological change and scale economies—that had hitherto defied easy reconciliation with accepted theories of economic growth (Romer 1986; 1990a, b). At the microeconomic scale, the results of a set of detailed, firm-level studies in several countries have forced a reappraisal of the accepted wisdom concerning the relationship between investment, productivity, and firm performance (Meurer, Sobel, and Wolfe 1987; Gertler 1993). Within this second avenue of progress, economic geography has made an important contribution to our understanding of the process by which mobile financial capital becomes ‘fixed’ in place as productive apparatus. Furthermore, this work has suggested important implications for the objectives and shape of industrial policy intervention. In this chapter I shall consider two fundamental questions: one that is more general in nature and another that is explicitly geographical. First, why have the returns from investment in new manufacturing technologies frequently been so disappointing? In addressing this question, I shall critically review some of the more significant insights produced by the ‘new growth theory’ in economics. This literature argues that investment is the motive force for technological change, since new capital goods by definition embody new, productivity-enhancing technologies. I demonstrate the extreme limitations of this perspective, drawing on the important conceptual and empirical work of economic geographers, economic sociologists, and other social scientists in the process.
