Rules of Access and Shifts in Demand: A Comparison of Log-Linear and Two-Sided Logit Models

Logan, John Allen
Working paper no. 1996-08


Hauser (1978) succinctly expressed a long-standing desideratum for the analysis of mobility regimes: to separate “rules of access” to social positions from “the interplay of supply and demand.” When an explicit, random matching model of opportunity is constructed from rules of access, with provisions for demand effects, it appears that log-linear models, as functions of odds ratios, do not in general satisfy Hauser’s requirement. Analysis and simulation show that the two-sided logit model proposed in Logan (1996a) is superior to log-linear and related models in this respect.
