The authors build a model of child labor and study its implication for welfare and fertility. Assuming there is a trade-off between child labor and human capital accumulation, we derive conditions under which child labor is socially inefficient. Even if parents are altruistic, child labor may...

The autors study the implications of the trade-off between child quality and child quantity for the efficiency of the rate of population growth. They show that if quantity and quality are inversely related then, even in the case of full altruism within the family, population growth is...

In the southern Great Plains of the United States, winter wheat is a dual purpose crop that produces forage for livestock grazing in the fall and winter, and a grain crop in the spring. Seasonal and interannual climate variations are pronounced and make it difficult to anticipate forage...

To be immediately useful in practical applications that employ daily weather generators, seasonal climate forecasts issued for overlapping 3-month periods need to be disaggregated into a sequence of 1-month forecasts. Direct linear algebraic approaches to disaggregation produce physically...

This investigation addresses a practical question from an agricultural planning and management perspective: are the NOAA/CPC seasonal climate forecasts skillful enough to retain utility after they have been downscaled to field and daily scales for use in crop models to predict impacts on crop...
