title: The role of equilibrium and disequilibrium in modeling regional growth and decline:  a critical reassessment.
abstract: The authors critically examine a 1990 study by Alan W. Evans concerning the assumption of interregional equilibrium in recent migration research.  "We here argue that Evans is unconvincing in his primary substantive argument; we provide an alternative reading of the literature that supports this assertion....[We then illustrate] the substantive issues in terms of a simple formal model that allows for both equilibrium and disequilibrium migration." The geographical focus is on the United States.  A reply by Evans is included (pp. 89-97).
