Allocations of research funds across programs are often made for efficiency reasons. Social science research is shown to have small, lagged but significant effects on U.S. agricultural efficiency when public agricultural R&D and extension are simultaneously taken into account. Farm management...

The estimated parameters of output distance functions frequently violate the monotonicity, quasi-convexity and convexity constraints implied by economic theory, leading to estimated elasticities and shadow prices that are incorrectly signed, and ultimately to perverse conclusions concerning the...

Recent empirical studies have found significant evidence of departures from competition in the input side of the bread,breakfast cereal and margarine end-product markets. In this study we specify a general duality model of profitmaximisation that allows for imperfect competition in the input and...

Profitability change can be decomposed into the product of a total factor productivity (TFP) index and an index measuring changes in relative prices. Many TFP indexes can be further decomposed into measures of technical change, technical efficiency change, scale efficiency change and mix...

This paper presents a metafrontier production function model for firms in different groups having different technologies. The metafrontier model enables the calculation of comparable technical efficiencies for firms operating under different technologies. The model also enables the technology...

A major environmental tragedy of modern times is the widespread arsenic contamination of shallow drinking water wells in rural Bangladesh which went unrecognized for years. Large numbers of people are now starting to show a range of symptoms long associated with chronic arsenic exposure. Rural...

The relative merits of different systems of property rights to allocate water amongdifferent extractive uses are evaluated for the case where variability of supply isimportant. Three systems of property rights are considered. In the first, variablesupply is dealt with through the use of water...

(Magill, M., Quinzii, M., 2002. Capital market equilibrium with moral hazard. Journal of Mathematical Economics 38, 149-190) showed that, in a stockmarket economy with private information, the moral hazard problem may be resolved provided that a spanning overlap condition is satisfed. This...

The relative merits of different systems of property rights to allocate water among different extractive uses are evaluated for the case where variability of supply is important. Three systems of property rights are considered. In the first, variable supply is dealt with through the use of water...

Large estimates of the benefits of microeconomic reform have been put forward in official studies. By contrast, Quiggin (1997) concludes that benefits of microeconomic reforms have been modest. A key area of disagreement relates to the claim that increased competition leads to increases in...
