Investment in Physical, Human Capital, Economic Growth and Life Expectancy in Bangladesh

This article studies the efficacy of the public investment in human capital and physical capital to raise income in Bangladesh over the period 1980–2016. This article also assesses whether the investment in human capital and income have raised life expectancy of the country. The Johansen cointegration test identifies a long-run relation of income with investment on education, health care and physical capital. The error correction mechanism (ECM) based on the cointegrating relation followed by the Wald test of Granger causality has found that these investments have caused income to rise with some lag periods. Robustness of these findings is confirmed by involving an autoregressive distributed lag (ARDL) model of cointegration followed by its ECM representation. On the other hand, the Johansen and ARDL methods of cointegration followed by their ECMs have also found a long-run relation of life expectancy with the investment in education, health care and income. A decisive role of the investment in health care and income on life expectancy is observed, while an unusual negative role of the investment in education is also found. However, positive value of the long-run coefficients of the education and health-care investments of the ECM-ARDL model indicate some long-run favourable impact of these investments on life expectancy in Bangladesh.
