| Using a unique survey data on agricultural traders in China in 2004, this study provides direct evidence on significance of interregional transport costs and their key determinants. Our major findings are as follows: (1) the trade barriers within China are dominated by transport-related costs but not artificial barriers, approximated by tolls and fines; (2) Labor and fuels costs are the most significant component of transport costs; (3) road quality is very important for transportation efficiency. Our results indicate that if increasing transport speed by 1 km per hour now, the fuel costs and total direct transportation costs for Chinese traders would reduce by 1.3% and 0.7% respectively. |

| 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 income, own-price and cross-price elasticities, respectively. Overall, AIDADS model has the best performance. The results indicate that the rank three models are not necessary always better than the rank two models. |

| Using a modified Fisher-Seater model with consideration of policy impacts, this paper attempts to tests the long-run neutrality of money supply on food prices in Germany after the launching of the Eurozone. The main findings include: (1) we can not reject the super neutrality of money for aggregated food prices; (2) However, staple food and its derived products – meat- are very sensitive to money supply, and their prices can increase to be much higher than money growth rate, perhaps due to speculative effects and demand effects; (3) Fresh or perishable products are usually less sensitive to money growth; (4) Most products decreased their prices after the launching of decoupling policy in Europe in 2003. The results can explain the links between money... |

| 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 that exist are becoming more complex. Contractual design in China is evolving from simple price-quantity contracts toward more complicated arrangements known as cooperation contracts or joint-stock cooperation contracts, designed to share risk and mitigate opportunistic behaviors by the contracting parties. Due to small farm sizes, the contracted amount in the typical contract in China is very small compared with Western countries, and each processor usually has a... |

| This paper uses a payment card approach to reveal consumers‟ willingness to pay for green food in China. We first present a brief introduction of the payment card approach and introduce several methods to estimate the WTP with payment cards, which we subsequently use to estimate WTP values regarding green vegetables, green meat and green eggs in China. Our results indicate that consumers in big cities are willing to pay a higher premium for green food and that WTP values are relatively higher for more expensive food than for cheaper food. In addition, the ratios of premium to price range mainly between 25% and 50% and WTP values obtained from interval midpoint approach are relatively higher than those calculated by other approaches. |

| 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 innovations. Due to contractual innovations, simple price-quantity contracts are evolving into complex cooperation contracts. Using data for over 500 state key processors in 2003 from the Chinese Ministry of Agriculture, we construct econometric models to study contractual choices, contract intensity, and their impacts on sales and profits for agricultural processors in China. The results indicate that capital and the number of contracted farmers are endogenous to contract... |

| By conducting a meta-analysis using 50 observations collected from 15 primary studies, we systematically analyze heterogeneities in consumer preferences for U.S. beef products and the results have valuable implications both from a policy perspective as well as from a methodological perspective. The main findings include that consumers in European and Asian countries are willing to pay less for U.S. beef products than those in North American countries and that the BSE incidence in the U.S. substantially damaged consumer preferences for U.S. beef products outside the U.S. but not in the U.S. The results with respect to methodological heterogeneities also indicate that choice experiments yield higher WTP values and that the sample size is negatively... |
