This paper probes effects of the evolvement of labor resources on technical efficiency in crop production in rural China. Based on twelve years of data on crop production of 30 provinces in China, a stochastic frontier production function model is used to measure crop production efficiency in three crop-functional areas—the production area, the consumption area, and the balanced area. Then effe...

This paper addresses the important question of whether public investment spending on economic infrastructure enhances economic growth and labor productivity in Argentina.

Using cointegratio...

This note reviews the targeting performance of Bolsa Família and its impact on inequality, poverty, consumption, education, health care, and labor force participation. Bolsa Família has several design and implementation characteristics that distance it from a pure human-capital-based conditional cash transfer model. For that reason, we compare the impact of Bolsa Família to that of other condit...

This paper attempts, using data from the British Labour Force Survey 1996, to examine to what extent differences in labour market outcomes between able-bodied and disabled men may be attributed to differences in endowments of human capital and associated productivity differences. Both labour force participation and selectivity corrected human capital equations are estimated and decomposition te...

Robert Solow received the 1987 Nobel Prize in economics for developing the leading model of economic growth. The model is based on the premise that cross-country differences in income per person are the result (primarily) of differences in national savings rates (savings finances increases in the capital stock). We illustrate its properties and show how it can be used as a tool for exploring th...

Alternative theoretical perspectives have been presented to explain internationally effective factors affecting immigration. For example, the orthodox explanation of migration is based on the concept of wage differentials as an important factor of international immigration. The world system approach declines to interpret theoretically international migration as a phenomenon between independent ...
