英文文献：Estimation of Import Demand for Fishery Products in the U.S. Using the Source-Differentiated AIDS Model
英文文献作者：Wang, Xiaojin,Reed, Michael
英文文献摘要：
Fishery product imports by the U.S. have been gradually increasing in recent years. The leading exporting countries include Canada, Chile, China, Ecuador, Indonesia, Thailand, and Vietnam. A source-differentiated Almost Ideal Demand System (AIDS) model and its Error Correction Model (ECM) version are employed to investigate the static and dynamic U.S. import demand for fishery products from the top seven countries using monthly data from January 1999 to September 2012. Long-run and short-run own-price, cross-price and expenditure elasticities are calculated.
