Modeling Agricultural Growth Multipliers
比较了不同固定价格模型对农业增长乘数的估计，发现半投入产出模型最合理，但价格内生模型显示其高估了10%到25%。
Abstract Agriculture's potential as an engine of third world growth depends, in large part, on the size of the production and consumption linkages it stimulates in rural regions. Current estimates of agricultural growth multipliers within rural regions vary widely, not only because economic structures differ across regions but also because the array of fixed‐price models most commonly used embody widely differing basic assumptions. Among fixed‐price models, the semi‐input‐output formulation projects the most plausible multipliers. But even they overstate the magnitude of growth multipliers by 10% to 25% according to the price‐endogenous model developed here.
