The impact irrigation efficiency and the loan deficiency payment have on the quantity of groundwater withdrawn and the agricultural cost of groundwater conservation in the Texas High Plains (THP) is estimated. The irrigation efficiency component utilizes the two most common irrigation...

Contractual breaches are very common in developing countries such as China. In order to prevent breaches of contract, the contractual designs between farmers and agricultural processors (Dragon Head Firms) in China are innovating in two ways: organizational innovations and contractual...

We compare the ability of three preference elicitation methods (hypothetical choices, non-hypothetical choices, and non-hypothetical rankings) and three discrete-choice econometric models (the multinomial logit, the independent availability logit, and the random parameter logit) to predict...

Consumers' preferences for credence attributes of a product may differ from each other, when facing the choices between branded and/or non-branded products. We test this hypothesis with conditional and mixed logit regression using data obtained by choice experiment surveys. The results suggest...

This study determines how production and trade policy distortions affected rice productivity in thirty-three rice-producing countries. A rice-productivity index for each country is constructed, and a model linking the productivity gap with policy distortions is presented. After controlling for...

Biomass yield to nitrogen response functions were determined for four perennial grass species. The species, nitrogen level, and harvest frequency that maximize expected net returns given the climate and soils of the U.S. Southern Plains were determined. For most combinations of biomass and...

In this paper, we examine the impact of reductions in barriers to migration on the consumption of rural households in China. We find that increased migration from rural villages leads to significant increases in consumption per capita, and that this effect is stronger for poorer households...
