The present study provides a quantitative assessment of the benefits from public agricultural research and development (R&D) for each continental state of the U.S. for 1949-1991, explicitly acknowledging for spillover effects. The novelty of this study resides in the use of spatial econometric...

A dynamic model of productivity measurement that incorporates public goods is developed. Cointegration is used to estimate dynamic derived demands and economies of scale in US agriculture, 1948-1994. The impact of public inputs on the steady state stocks of private capital and their shadow...

"This paper examines price policies and agricultural productivity in 18 developing countries over the period 1961-1985. We measure productivity with both a nonparametric Malmquist index and a production function, confirming previous findings of declining agricultural productivity, but with...

Young (1995) estimated Total Factor Productivity (TFP) growth for Hong Kong, Taiwan, Singapore and South Korea. He reported moderate growth rates for these four regions. This means that rapid growth of GDP in these four economies is due mainly to fast increase of inputs. Young (2000) also...

This paper examines changes in agricultural productivity in18 developing countries over the period 1961-1985. We use the nonparametric, output- based Mamquist index to examine whether the results from such approach confirm results from other methods that have indicated declining agricultural...

A three period overlapping generations model is developed to investigate the impact of shorter life expectancy due to disease, on human capital investment decisions and income growth. This research is particularly relevant to Sub-Saharan Africa given the dramatic reduction in life expectancy due...

This paper examines agricultural policies in 18 developing countries over the period 1961-1985. We measure productivity with both a nonparametric Malmquist index and a production function, confirming previous findings of declining agricultural productivity, but with sufficident inconsistencies...

This study shows that agricultural policies in Argentine agriculture substantially reduced the growth rate of output in 1940-1980.
