Three essays on job satisfaction, meat consumption and transgenic soybean
This dissertation is to study the issues of Chinese worker's job satisfaction, Chinese consumer's meat consumption pattern change, and the potential economic effect of adopting Sudden Death Syndrome (SDS) resistant soybean in the U.S. In Chapter 1, we use a Mincer earnings function to generate expected wages for each worker based on their skills and region, and use the unexplained wage as the objective measure of treatment to study how the objective measures based on these would affect Chinese worker's perceptions concerning employment. We find that the observed and the unexplained wage positively affect job satisfaction, promotion satisfaction and social status. The effects of income inequality on the three employment perception measures depend on their observabilities. Holding unexpected wage constant, old workers have higher level of job satisfaction and social status than their young counterparts; old, female, rural and educated workers have higher level of job satisfaction and social status; old, female and rural workers report higher level of promotion satisfaction. Finally, workers in government departments have the highest level of the three employment perception measures. In Chapter 2, we apply a censored demand system approach with an Almost Ideal Demand System specification to study what Chinese consumer's meat consumption patterns were like and how it changed over time, across provinces or across income groups. We find that as household income increases, meat expenditures increase, with pork capturing a larger share. The general pattern for elasticities holds across both provinces and income groups. Pork and other meats are necessities while beef, mutton and chicken are luxury goods. The pattern change of meat consumption in China implies a great opportunity for U.S. pork export growth if China removes retaliatory duties imposed on U.S. pork exports in the background of U.S.-China trade war. In Chapter 3, we adopt a crop sector model to study the potential economic impacts if the SDS resistant soybean variety was adopted historically. We find that if SDS resistant soybean variety was adopted in history, total equilibrium supply would have increased by 0.1%-0.5% from 2000-2017, and soybean price would have decreased by 0.1%; crush, export and stocks would have decreased by 0-0.2%, increased by 0.1%-0.4%, and increased by 0.1%-3.8%. Adoption of SDS resistant transgenic soybean variety would have brought larger benefits to producers than consumers in general, and producer benefits would have peaked in the years with the largest outbreaks of SDS.
