Rotterdam Model

Using annual Japanese fresh fruit import data from 1971 to 1997, this study analyzes the import patterns of Japan's seven most popular fresh fruits by implementing and testing a general differential demand system that nests four alternative import demand specifications. When tested against the general system using the five-good case (bananas, grapefruits, oranges, and lemons and aggregating pineapples, berries, and grapes), the analysis rejects the Almost Ideal Demand System and National Bureau of Research specifications but does not reject Rotterdam and Central Bureau of Statistics models. When estimated using the six-good case (bananas, grapefruits, oranges, lemons, and pineapples and aggregating berries and grapes), the analysis rejects all specifications except the Rotterdam model.

Meat Demand

Despite rising the economic level of the Iraqi citizen, but there was a shortage in completing consumer's needs of animal protein. The high price of some sources of animal protein led capita turning to other alternatives to fill shortage and these turnings made destabilizations in demand of required quantities of these goods, hence on its productivity and imported quantities. This paper aimed to evaluate the functions of fish, chicken and red meat demand in Iraq due to fish considered as a good alternative of meat as it is an important source of animal protein. Demand function were evaluated according to linear approximation model of Almost Ideal Demand System (AIDS), the study showed that the special Marshal's price elasticity was the highest for chicken followed by fish and red meat. The elasticity of expenditure of red meat showed that it considered luxury goods where it was more than 1 and there was no satiate in, while the elasticity of expenditure of fish and chicken could be essential goods as it was less than 1 and that represented the reality of Iraqi citizen.
