Elasticity of Factor Substitution in Police Agencies Evidence From Florida
利用佛罗里达州市政警察部门1982-1983年的数据，估计多产品超越对数成本函数，计算警察服务生产中要素替代弹性，发现各投入对之间的替代弹性显著不等于1，与柯布-道格拉斯生产函数不一致。
A multiproduct translog cost function is estimated and used to calculate elasticities of factor substitution in the production of police services. The data come from Florida's municipal police departments and are for 1982–1983. It is found that substitution elasticities between any pair of inputs in police production are significantly different from unity. This result is inconsistent with the Cobb–Douglas production function—a functional form that has been extensively employed in empirical studies of police production.
