An econometric analysis of the olive oil market in Italy
构建了一个包含内生政策变量的条件需求系统，基于三种脂肪的AIDS模型分析意大利橄榄油市场，发现橄榄油需求对自身价格敏感，与种子油和黄油呈净替代关系，且行业政策工具效果有限。
The paper analyses the olive oil market in Italy. In the specified model, consumption and import demands form conditional demand systems and the relevant policy variables are endogenous. Empirical evidence based on a three fat AIDS shows that olive oil is elastic with respect to the group expenditure, that olive oil, seed oils and butter behave like net substitutes and as gross complements, and that olive oil conditional demand is rather reactive to its own price. The policy multipliers support answers which are coherent with the assumptions, but contradict common opinions. In particular, sectoral instruments are not that effective in enhancing the market.
