Asset Fixity and Investment Asymmetry in Agriculture
检验农业专用资本是否比普通资本更难处置，通过分析24个年度资本序列，发现8个序列存在显著的投资与处置不对称性，尤其体现在拖拉机等专用车辆上。
Abstract Fixed asset theory implies that it is more difficult to dispose of capital specific to agricultural production than to add to the stock of specialized capital. This theory is tested by determining whether transitions between states of disinvestment are as likely as transitions between states of investment. Of the twenty‐four annual capital stock series analyzed, evidence of asymmetry between investment and disinvestment is strong in eight cases, weak in four, and insignificant in twelve. There is considerable, although mixed, evidence of asymmetry for tractors (farm and nonfarm) and other specialized vehicles since World War II and for agricultural machinery.
