The inclusion of two inventory variables in the model only increases the number of parameters by two. Results indicate that frozen tunas are more likely to be close substitutes, fresh and frozen tunas of the same species are also likely to be substitutes, and inventory had significant impacts on auction prices.

Beginning January 1st 2003, food containing more than 5% of GM ingredients must be labeled. Taiwan imports most of its soybeans from the United States. In order to assess the effects of the new policy, a telephone survey was conducted in 2002. A total of 257 interviews

According to the 1996 Taiwan's Input-Output tables, there are 160 commodities and sectors. The fishery sector is specified as one single sector. Even though the fishery products are highly substituted among consumers, the fishery sector should be disaggregated to distant water fishery, which targets the export market, and the aquaculture and offshore/coastal fisheries, which mainly target the domestic market. For example, the aquaculture and offshore/coastal fishery commodity outputs value for domestic market would decrease by 4.29% and 10.73%, respe...
