Abstract: Related literature finds that human capital proxied by cognitive abilities is an important antecedent of numerous specific life outcomes. The purpose of this study is to extend existing evidence by investigating the link between cognitive skills and income in Tajikistan. Tajikistan is a landlocked low-income country situated in Central Asia. Its population is 9.1 million people and gross domestic product per capita of US$822. According to the World Bank, Tajikistan has made significant progress in decreasing poverty levels from 83% in 2000 to 29.5% in 2017. The baseline results are reported in Table 2. The results in Column 1 demonstrated the link between cognitive abilities and income without control variables (unconditional model). As expected, cognitive abilities are positively and significantly related to income (a1 = 0.0715, p < 0.01). The results from the unconditional model suggest that one standard deviation increase in cognitive abilities is associated with a nearly 17% increase in income. The results in the study offer preliminary evidence on the link between cognitive abilities and income in Tajikistan. However, the results of the study also suggest that both measures of human capital are positively related to income. Therefore, policymakers in Tajikistan should invest greater resources to health care, education and training programs as cognitive skills can be built in particular in the early stages of the life cycle. Indeed, Tajikistan has a significant potential for economic growth model driven by human capital. According to the World Bank, the adult literacy rate in Tajikistan is 100%, which is significantly above of what is observed in other developing countries. This may imply that the human potential in this country is considerable, and further investment in soft and hard skills would have a positive impact on economic growth.
