The Effect of Household Wealth on Fertiliser Use in the Presence of Uncertainty
研究了在化肥效果存在不确定性的情况下，家庭财富如何影响农民化肥使用量，发现高财富和低财富农民的反应不同，且财富效应方向随财富水平变化。
Previous studies of wealth effect on fertiliser use have produced mixed results on the direction of the impact. Our article looks at this issue from a different perspective by considering the presence of doubts, such as about the true content or general effectiveness of fertiliser. We show theoretically that there could be different responses between the high-wealth and low-wealth farmers. We analyse also the wealth effect empirically using household panel data from the Hebei province of China. The results indicate that the direction of wealth effect does indeed change across the different levels of farmers’ wealth.
