Asymmetry and Nonstationarity in the Farm Size Distribution of Wisconsin Milk Producers: An Aggregate Analysis
利用总量数据构建马尔可夫模型，检验威斯康星州奶牛场规模演变的非平稳性和非对称性，分析价格、利率、债务、干旱及乳制品终止计划对农场增长和进出市场的影响。
Abstract A Markov model is developed to test the nonstationarity and asymmetry of factors affecting the evolution of Wisconsin dairy farms using aggregate data. The model is used to examine how prices, interest rates, debt, drought, and the dairy termination program affected farm growth and the entry and exit of Wisconsin dairy farms by size categories during 1972–92.
