A new market for an old food: the U.S. demand for olive oil
利用月度进口数据估计需求系统，发现美国对欧盟特级初榨橄榄油的收入弹性大于1，而非特级初榨橄榄油缺乏收入弹性；橄榄油整体缺乏价格弹性，不同特性和产地的橄榄油之间高度可替代，但与其他植物油不可替代。
Abstract While U.S. consumption of olive oil has tripled over the past two decades, nearly all olive oil continues to be imported. Estimation of a demand system using monthly import data reveals that the income elasticity for virgin oils sourced from EU is above one, but demand for nonvirgin oils is income‐inelastic. The demand for olive oil as a single product is price‐inelastic. Differentiated by product characteristic and origin, olive oils are highly substitutable with each other but not with other vegetable oils. News about the health and culinary benefits of olive oil and the spread of Mediterranean diet contribute significantly to the rising demand.
