Dynamics of Beef Cow Herd Size: An Inventory Approach
研究肉牛母牛存栏量的动态变化，通过模拟分析经济因素冲击对淘汰和补栏决策的短期与长期影响，发现经济变化对年轻牛群影响最大，并通过年龄动态影响牛周期。
Abstract Cow herd inventories are the primary determinant of beef supply. The principal decisions determining inventories are studied in a dynamic framework. Short‐run and long‐run impacts of one‐time shocks in economic factors influencing culling and replacement decisions are estimated via simulations. Changes in economic factors have the greatest impact on younger members of the herd. These changes have long‐term impacts on inventories through their influence on age dynamics. Impacts on age dynamics could influence the cattle cycle.
