Using Monte-Carlo simulation, , we compare the most popular demand systems including the LES, AIDS, BTL, QES, QUAIDS and AIDADS, and find that different models actually have different advantages in estimating different elasticities. Specifically, QES, AIDS and AIDADS models are the best in...

Contracts are widely used by agricultural processors for purchasing inputs not only in developed countries but also in developing countries such as China. The total number of formal, written contracts between farmers and food processors is increasing rapidly in China, and the formal contracts...

This study finds that market service and environment are very important for both contract choices and enforcement. Better market service and environment can increase the...

There are many projections for China’s food demand, and the projection results differ significantly from each other. Different values for income elasticities could be a major reason. This study projects meat and cereals demand for China based on a meta-analysis of the income elasticity...
