ABSTRACT A dynamic panel data (DPD) model is estimated to assess the contribution of the average schooling years, the education expenditure and the inventive coefficient—as an approximation for innovation—to the increased productivity of the Mexican states. The potential difficulties of endogeneity and serial correlation are controlled by adopting system General Method of Moments (GMM) procedures. The findings are compatible with the theory. The importance of the lags is confirmed and the positive and significant impacts on producti...

ABSTRACT It is apparent that heat can hamper timing and productivity of construction work that occurs outside. There are many types of construction changes and each type can have an effect on labor and machinery productivity. But what is the effect of extreme heat & humidity and dust storm on construction industry can occur either indoor or outdoor work. Construction materials production data from main four companies in the Gulf region over five years period were collected. This study found that the adverse sever summer climate of heat and dust storms lead to a significant reduction in production. An average of week with six days during summers ...

It seems that human competencies form an intangible asset, which in turn forms sustainable, unique strengths that are key to firm-specific superior performance. Evidence-based human resource management argues that gaining competitive advantage through human capital development should be verified and estimated scientifically. This article presents the scientifically solid theory of Human Capital Production Function, which explains tangible and intangible human capital’s wo...
