CHANGES IN ELASTICITIES OF INTERSTATE MIGRATION: IMPLICATION OF ALTERNATIVE FUNCTIONAL FORMS*
讨论了线性、对数线性等简单函数形式研究州际迁移的问题，引入了一般形式及其估计方法，并使用1970年美国48个州的人口普查数据估计参数。
"... Problems of using a linear, log-linear, or other simple functional forms for the study of interstate migration have been discussed. A general form and the procedure to estimate it have been introduced. 1970 [U.S.] Census data for the 48 contiguous states have been used to estimate the parameters in the general form."
