AGRICULTURAL PRICE PROTECTION, IMPORT DEPENDENCE AND ECONOMIC DEVELOPMENT: THE CASE OF WHEAT
通过跨国时间序列数据，分析小麦价格保护的决定因素，发现经济发展水平和进口依赖度会推高保护程度，且不同国家和时期存在差异。
This article analyses determinants of agricultural price protection for one important food, wheat, in a pooled cross‐country and time‐series analysis. For the aggregate sample it is shown that wheat price protection increases with a rising level of economic development and with a growing import dependence in wheat. Beyond this general pattern, the paper shows that the variation in wheat price protection can be significantly better explained if qualitative variables are introduced additionally into the model. For example, in Japan, in the Northern European countries and during the commodity price boom (1973–75), wheat price protection followed a specific pattern. Income elasticities and import‐dependence elasticities of wheat price protection are computed for all countries in 1968–80, and additionally for various sub‐regions and sub‐periods.
