Leapfrogging: A Theory of Cycles in National Technological Leadership

Much recent work has suggested that endogenous technological change tends to reinforce the position of the leading nations. Yet from time to time this leadership role shifts. We suggest a mechanism that explains this pattern of -leapfrogging- as a response to occasional major changes in technology. When such a change occurs, leading nations may have no incentive to adopt the new ideas; given their extensive experience with older technologies, the new ideas do not initially seem to be an improvement. Lagging nations, however, have less experience; the new techniques offer them an opportunity to use their lower wages, to break into the market. If the new techniques eventually prove to be more productive than the old, there is a reversal of leadership.

Leapfrogging in International Competition: A Theory of Cycles in National Technological Leadership.

Endogenous-growth theory suggests that technological change tends to reinforce the position of the leading nations. Yet sometimes this leadership role shifts. The authors suggest a mechanism that explains this pattern of 'leapfrogging' as a response to occasional major changes in technology. When such a change occurs, the new technology does not initially seem to be an improvement for leading nations, given their extensive experience with older technologies. Lagging nations have less experience; the new technique allows them to use their lower wages to enter the market. If the new technique proves more productive than the old, leapfrogging of leadership occurs. Copyright 1993 by American Economic Association.

Non-linear geographics and the economics of transition and democratization

International audienceThe purpose of this study is to analyse the effects of geography on the transition process in authoritarian political regimes, and to investigate the nature of the links between political change, economic reforms and geographical location. A simple model of transition and democratization is presented wherein we show that the effectiveness of repression by the incumbent elite is a negative function of the distance to the 'free world'. In consequence, geography has conflicting effects on shifts in political power. This article provides a rationale for the counterintuitive fact that the first authoritarian country to start a transition process towards democratization is not necessarily the one nearest to the free world
