The direction of migration: a dynamic general equilibrium model

A two-sector dynamic general equilibrium model is developed "to investigate the direction of migration in response to differing demographic and consumption demand behavior, as well as variations in production conditions." The model, which involves a rural sector and an urban sector, incorporates "returns to scale and the natural rate of sectoral population growth as important determinants of the direction of migration, in addition to price and income elasticities, and the sectoral technical change rate with which...previous studies dealt."     

THE NEIGHBOURHOOD EFFECT IN A LOCAL ELECTION

One of the more popular ideas in electoral geography is that there is a positive correlation between residential proximity and voting behaviour. Often referred to as the neighbourhood effect, the idea is quite simply that individuals within a given local area tend to vote similarly. The process involves, it is suggested, social contacts between neighbours leading to political discussion and information flow which exerts an influence on the way people vote. Closely related to, but distinguishable from the neighbourhood effect is the friends-and-neighbours effect whereby neighbours of a particular candidate will tend to know him better, discuss him more, and support him more avidly than they will other candidates. Since the concepts of the neighbourhood effect and the friends-and-neighbours effect have been adopted into the literature of political geography, and have become central as explanatory models for certain spatial patterns of voting behaviour,¹ the rather inconclusive and contradictory findings of researchers using these concepts require examination, and the concepts and process require an empirical test.     

PROCEDURES FOR COMPARING AND COMBINING RADIOCARBON AGE DETERMINATIONS: A CRITIQUE

Archaeologists, along with other Quaternary researchers, seldom rely upon a single radiocarbon determination to provide an estimate of the age of the phenomenon which is the object of their study. There is an evident need for an explicitly formulated procedure for comparing sets of radiocarbon determinations from the same and from adjacent strata or sites, and for combining these where statistical and archaeological criteria indicate that this combination is warranted. The present contribution provides explicit modelling for a series of recommended procedures, a critique of previous methods, and paradigms for application of the recommended procedures.
