Food Import Demand in the Czech Republic
研究了1990年代转型期捷克对16个低层和4个高层食品组的进口需求，用双月数据估计了自身价格弹性、交叉价格弹性和支出弹性。
This paper provides an overview of Czech food import demand in the transition period of the 1990s. It provides econometric estimates of own‐ and cross‐price elasticities as well as group expenditure elasticities of Czech import demand for sixteen lower level and four upper level food groups. Based on the Hausman test for endogeneity, which supported the hypothesis that Czech import prices were exogenously determined outside of the Czech economy, we estimated five demand models as direct‐demand systems of the AIDS type. The econometric estimation of elasticities used bimonthly data from March 1993 to August 1997.
