The Poultry Market: Demand Stability and Industry Structure
研究美国家禽肉需求在1970年代初的转变，发现需求曲线外移且与猪肉从替代变为独立关系；通过外生性检验支持竞争性、规模报酬不变的产业结构。
Abstract The stability of the demand for poultry meat and specification issues in its estimation are explored. The analysis concludes that the demand for poultry meat shifted out in the early 1970s. At the same time, the demand relationship between poultry and pork changed from substitution to independence. A second conclusion is that poultry price is predetermined for demand in annual U.S. data, while quantity is not. A predetermined price suggests several market structures. Exogeneity tests are performed to distinguish among them. The results are consistent with a competitive, constant returns‐to‐scale‐industry facing elastic factor supplies.
