Localized technological change and the quest for productivity growth
In recent years there has been renewed interest upon the analysis of the direction of technological change and its effects on the actual efficiency of production processes after the introduction of non-neutral technological changes. The empirical evidence shows that significant changes in the distribution of revenue across production factors have been taking place in the last thirty years in the major OECD economies; specifically in many countries the share of labor has diminished while the share of capital has increased.
These changes in the distribution of income can be considered the consequence of the introduction of directed technological changes biased towards labor saving innovations aimed at reducing the use of labor after the increase of unit wages so as to make the most efficient use of capital, by now the most abundant production factor. The paper presents a framework of analysis based on a model of localized technological change that accounts for both the shift and the bias of technological change in the context of an induced innovation approach. This work presents also preliminary cross-country evidence on the direction of technological change and its effects.
