Rice in Asia: Is It Becoming an Inferior Good?
基于1961-1985年14个亚洲国家的时间序列和截面数据，发现大米收入弹性下降甚至转负，表明大米正成为低档商品，可能导致亚洲大米过剩和价格下行压力。
Abstract Empirical results using time‐series and cross‐sectional data indicate that rice in Asia is becoming an inferior good. Income elasticities declined and in some cases became negative between 1961 and 1985 in most of the fourteen Asian countries studied. Accordingly, domestic demand for rice in these countries is not likely to grow as rapidly as it has in the past. As a consequence, there is a potential for excess supplies of rice to develop in Asia, putting downward pressure on rice prices. While governments in Asian countries may need to adjust their rice policies in the future, world rice suppliers may need to develop new markets for rice.
