Market price response of world rice research
以研究论文数量衡量全球水稻研究产出，发现其对国际米价短期波动高度敏感，暗示公共农业投资可能被价格周期误导，导致粮食短缺与过剩交替出现。
Using the total number of research publications as a proxy, the output of rice research in the world is estimated to be highly responsive in the short run to price fluctuations in the international rice market. The results suggest a danger of the inducement mechanism of public investment in the agricultural production infrastructure being misguided by cyclical price changes, thereby leading to recurrent food shortages and oversupplies in a cobweb-like manner.
