| This report documents data and other information gathered from a survey of rural households in China. The survey was conducted as part of a research project aimed at assessing the potential for meat and feed grain exports to China. Responses to the survey questions provide information about grain and livestock production practices, costs of production, animal inventories, and feeding practices. The report describes the survey and collection process, summarizes selected data from the survey, and provides anecdotal information about livestock production and marketing in Chongqing, Sichuan, Shandong, and Jilin provinces. |

| This research develops a mixture regression model that is shown to have advantages over the classical Tobit model in model fit and predictive tests when data are generated from a two step process. Additionally, the model is shown to allow for flexibility in distributional assumptions while nesting the classic Tobit model. A simulated data set is utilized to assess the potential loss in efficiency from model misspecification, assuming the Tobit and a zero-inflated log-normal distribution, which is derived from the generalized mixture model. Results from simulations key on the finding that the proposed zero-inflated log-normal model clearly outperforms the Tobit model when data are generated from a two step process. When data are generated from a Tobit... |
