Which of the following comments is correct?
I. China’s exceptional growth between 1980 and 2000 supports the convergence hypothesis.
II. The widening gap between Bulgaria and the United States supports the convergence hypothesis.
III. The low growth rates of Bulgaria, Ecuador, and Nigeria could be explained by low interest rates and high investment.
IV. Because Nigeria’s growth rate increased, its per capita real GDP will eventually surpass that of the United States and the Netherlands.
V. The differences between high-income countries (the United States and the Netherlands) and low-income countries may be explained by lack of political stability and property rights.
VI. More education and research and development in Bulgaria, Ecuador, and Nigeria will foster higher economic growth rates in these countries.
The data given in the link provided in the question on their own does not support any of the comments. Rather than being comments, these are in the nature of hypothesis that have to be either logically proved or empirically established. These are more in the casual remarks and not useful from professional economist’s angle.
