The technology clubs: The distribution of knowledge across nations

The convergence clubs literature in applied growth theory suggests that countries that differ in terms of structural characteristics and initial conditions tend to experience diverging growth performances. What is the role of technological knowledge for the formation of clubs? The paper investigates this unexplored question by carrying out an empirical study of the cross-country distribution of knowledge in a large sample of developed and developing economies in the 1990s. The results indicate the existence of three technology clubs characterized by markedly different levels of development. The clubs also differ with respect to the dynamics of their capabilities over the decade, as the most advanced group and the intermediate one are found to be much more dynamic than the large cluster of less developed economies.
