Ongoing and Other Research Topics of Interest
Topic
Objective
The catfish and baitfish industries are recognized as an important component of the food fish and sports fish aquaculture industry in the USA. However, the actual contribution of the industries to the local economies is not well documented. Continued growth of the industry requires support from policy makers and other agencies involved in research and development. To ensure support, there is a need to document the impact of the industries in terms of creating new dollars, jobs, and income to the local community.
Policy Options to Stabilize Catfish Prices
The catfish industry is recognized as an important component of the food fish aquaculture industry in the USA. Due to different pricing and trading policies, the farm-get prices are currently below the break-even price. Price stabilization polices to keep catfish farmers in business need to be devised (e.g., What will be the impact of including catfish products in school lunch and food stamp programs on farm-get prices?)
Demand Analysis Using Household Expenditure Data
Zero expenditures for specific commodity is a major problem in household expenditure surveys. There are several reasons for non-purchases (zero expenditures): some households will never buy the commodity; existing food inventories in the household; and potential buyers (traditional corner solution) who will buy at a given or specific economic factors. How can we use this information to estimate demand systems using short duration cross-sectional data?
Estimating Willingness to Pay (WTP) from Heterogeneous Population
Willingness to pay studies often involves individuals with different taste and preferences, income levels and gender (i.e., the sample is usually heterogeneous). The objective is to learn how mixture distributions can be used in estimating WTP.
Regional Economic Impact of East Africa Community (Tanzania, Kenya Uganda)
Economic blocks are formulated to strengthen existing country economies and stimulate economic growth in the region. In such undertaking, in the short-run, some countries lose while other countries gain. This research is aimed to answer the questions on: who are the losers and by how much; what should be the long-term policy strategies to compensate the losers; and what policy options could stimulate agro-based industries under a "win-win" situation.
