英文文献：Hysteresis And The Shortage Of Agricultural Labor
英文文献作者：Bryant, Amy,Richards, Timothy J.
英文文献摘要：
The GAO disputes growers' claims of a labor shortage, using unreliable farm employment data rather than relative wages. A shortage, implying a failure of intersectoral arbitrage, may arise due to hysteresis in labor movement. Estimates find the probability of a farm labor shortage (30%) three times that of a surplus.
