The main objective of the study was to investigate the long run and short run impact of human capital on economic growth in Ethiopia (using real GDP per capita, as a proxy for economic growth) over the period 1974/75-2010/2011. The ARDL Approach to Co-integration and Error Correction Model are applied in order to investigate the long-run and short run impact of Human capital on Economic growth. The finding of the Bounds test shows that there is a stable long run relationship between real GDP per capita, education human capital, health human capital, labor force, gross capital formation, government expenditure and official development assistance. The estimated long run model revels that human capital in the form of health (proxied by the ratio of public expenditure on health to real GDP) is the main contributor to real GDP per capita rise followed by education human capital (proxied by secondary school enrolment). Such findings are consistent with the endogenous growth theories which argue that an improvement in human capital (skilled and healthy workers) improves productivity. In the short run, the coefficient of error correction term is -0.7366 suggesting about 73.66 percent annual adjustment towards long run equilibrium. This is another proof for the existence of a stable long run relationship among the variables. The estimated coefficients of the short-run model indicate that education is the main contributor to real GDP per capita change followed by gross capital formation (one period lagged value) and government expenditure (one period lagged value). But, unlike its long run significant impact, health has no significant short run impact on the economy. Even its one period lag has a significant negative impact on the economy. The above results have an important policy implication. The findings of this paper imply that economic performance can be improved significantly when the ratio of public expenditure on health services to GDP increases and when secondary school enrolment improves. Such improvements have a large impact on human productivity which leads to improved national output per capita. Hence policy makers and / or the government should strive to create institutional capacity that increase school enrolment and improved basic health service by strengthening the infrastructure of educational and health institutions that produce quality manpower. In addition to its effort, the government should continue its leadership role in creating enabling environment that encourage better investment in human capital (education and health) by the private sector.
Tourism-led growth hypothesis argues that international tourism is a source of economic advancement through generating foreign currency, creating employment opportunities, stimulating greater investments in infrastructure and inspiring the development of other economic sectors that ultimately improved the living standard of the citizens of a country. Knowing the importance of tourism sector, Ethiopia has taken this sector as a strategy to achieve its short and long run economic objectives. Therefore, the principal objective of this study is to validate the Tourism-Led growth hypothesis (TLGH) in Ethiopia over the annual period 1991-2018. To attain the envisaged objective, the standard Augmented Dickey-Fuller (ADF) and Phillips-Perron (PP) unit root tests were applied to check the stationarity of each series. To scrutinize the long run relationship between tourism and economic growth, ARDL bound test of cointegration was applied. In addition, pairwise Granger causality test was used to identify the direction of causality between tourism receipt and economic growth. The empirical findings confirm the existence of long run relationship between tourism receipt, economic growth and other control variables. The results of the pairwise Granger causality also predicted unidirectional causality running from tourism receipt to economic growth in long run. This validates the tourism-led growth hypothesis for Ethiopia. Hence, policy makers should focus on promoting and development of the untapped tourism industry of the country to augment economic growth in Ethiopia.2 tourism-led growth hypothesis for Ethiopia.The remaining part of the paper is organized as follows: Section-two briefly reviews theoretical and empirical literature. Section-three deals with research methodology and model specification. Section-four consists of the result and discussion part of the paper. The last section deals with brief conclusion and recommendation.
