Our paper focuses on the dynamics of development of human capital in economic development cycles (as described, for example, in the works of Becker or Barro). In the course of this research, we created an econometric model based on the modified Mankiw-Romer-Weil equation of the Cobb-Douglas...

This paper provides empirical evidence that there is no absolute convergence between the GDP per capita of the developing countries since 1950. Relying upon recent econometric methodologies (nonstationary long-memory models, wavelet models and time-varying factor representation models), we show...
