Over the past 50 years and longer, the supply of food commodities has grown faster than the effective market demand, in spite of increasing population and per capita incomes. Consequently, the real (deflated) prices of food commodities have steadily trended down. The past increases in...

The main purpose of this paper is to present estimates of the marginal products and rates of return to the four major categories of agricultural research conducted by U.S. agricultural experiment stations (cash grains, poultry, dairy, and livestock).

A number of very careful econometric studies have been interpreted as showing that publicly funded research and development conducted by private firms has had little discernable impact on firm level profits or productivity. In contrast historical studies have shown that military and...

Poverty measurement with data whose reference period is one year masks family exposure to poverty that only lasts for part of the year. We use quarterly expenditure data and decomposable severity of poverty indexes to quantify consumption-based intra-annual poverty, determine its causes and its...

This paper reviews some of the recent major research findings concerning the effect of household behavior on food consumption and nutrition. Important extensions to the understanding of household behavior have been made in the areas of the impact of income and price changes, agricultural...

This paper estimates a complete demand system for food for the United States using an extension of the Almost Ideal Demand System (AIDS) with household and aggregate data. The major purpose is to explore the implications of aggregation over consumers. Empirical evidence, based on data from the...

Price endogeneity has been ignored in previous analyses of food demand in China. We exploit farm price data collected from the China National Bureau of Statistics to account for price endogeneity using reduced form price equations. Applying our unique econometric approach to the analysis of...
