Concerning Inequality, Technology Adoption, and Structural Change
Empirical evidence suggests that there has been a divergence over time in income distributions across countries and within countries. Furthermore, developing economies show a great deal of diversity in their growth patterns during the process of economic development. For example, some of these countries converge rapidly on the leaders, while others stagnate, or even experience reversals and declines in their growth processes. In this paper we study a simple dynamic general equilibrium model with household specific costs of technology adoption which is consistent with these stylized facts. In our model, growth is endogenous, and there are two-period lived overlapping generations of agents, assumed to be heterogeneous in their initial holdings of wealth and capital. We find that in a special case of our model, with costs associated with the adoption of more productive technologies fixed across households, inequalities in wealth and income may increase over time, tending to delay the convergence in international income differences. The model is also capable of explaining some of the observed diversity in the growth pattern of transitional economies. According to the model, this diversity may be the result of variability in adoption costs over time, or the relative position of a transitional economy in the world income distribution. In the more general case of the model with household specific adoption costs, negative growth rates during the transitional process are also possible.
