Using estimates of earnings functions in Ghana, this paper examines patterns of labor market segmentation with regard to formal and informal employment. Persistent earnings differentials are used as indicators of limited mobility across segments of the employed labor force. We find evidence of labor market segmentation between formal and informal employment and between different categories of i...

This paper proposes a one-sector multigroup growth model with endogenous labor supply in discrete time. Proposing an alternative approach to behavior of households, we examine the dynamics of wealth and income distribution in a competitive economy with capital accumulation as the main engine of economic growth. We show how human capital levels, preferences, and labor force of heterogeneous hous...

We use a general equilibrium model to study the impact of fully funding social security on the distribution of consumption across cohorts and over time. In an initial stationary equilibrium with an unfunded social security system, the capital-output ratio, debt-output ratio, and rate of return to capital are 3.2, 0.6 and 6.8%, respectively. In our rst experiment, we suddenly terminate social se...

P roductivity promotion has received a key attention in contemporary macroeconomic analysis. Productivity of labor driven, in particular, by human capital (i.e. health and education), is seen vitally more important. Labor qualities in terms of health and education (treated as flow and stock variables), have a bearing on labor productivity. The main objective of this paper is to ident...

skilled labor force is very important in economic growth. workers become skilled when they are healthy and able to be educated and work. in this study, we estimated the effects of health indicators on labor supply. we used labor force participation rate as the indicator of labor supply. we categorized this indicator into 2 indicators of female and male labor force participation rates and compar...

The expected change in population age structure in virtually all industrialized countries—as well as in many developing countries—will lead to a substantially higher proportion of older people in the world. The aging process deeply affects future labor, financial, and commodity markets. On a macroeconomic level, labor is becoming relatively scarce in the aging countries while capital becomes re...

Were ordinary factory workers unskilled and was technology “de-skilling” during the Industrial Revolution? I measure foregone output to estimate the human capital investments in mule spinners and power loom tenders in ante-bellum Lowell. These investments rivaled those of craft apprentices. Although factory workers were unskilled in a sense, the implementation of this technology depended on the...
