Filani M. O. (1973) Air traffic forecasting: An input-output technique approach, Reg. Studies 7, 331–338. In the United States, air traffic forecasting has been too aggregative and narrow with little or no consideration for the highly interdependent nature of traffic exchanges among the cities within the entire national air transport network. The present paper is an attempt to eliminate this deficiency through the use of the basic input-output technique. Comparisons are made between actual and predicted traffic for the nation's 14 major cities for five consecutive time periods. The paper also demonstrates the temporal internal consistency in the interaction coefficients among the cities and on this basis predicts their 1975 total traffic. [ABSTRACT FROM PUBLISHER]

Manhertz H. G. (1970) Some econometric considerations in studying regional demand patterns in the United States, Reg. Studies 4, 107–115. Regional differences in demand may be largely attributed to the degree of spatial heterogeneity which is characteristic of a given geographic area. To the extent that the pattern of demand for a region or contiguous regions can be unique, national demand analysis should be carried out within the disaggregative framework of regional demand functions. The model developed in this article involves a basic demand function explaining quantity demanded in terms of disposable income, price and an urbanization index for each of nine regions in the continental United States. Alternative formulations are developed for each region in order to examine the probable existence of simultaneity and multicollinearity among the variables. The model is evaluated in terms of the demand for processed vegetables and shows that most of the interregional variations in demand may be attributed to urbanization, i.e. farm-nonfarm population mix.

Cameron G. C. (1968) The regional problem in the United States—Some reflections on a viable Federal strategy, Reg. Studies 2, 207–220. In the U.S. a Federal policy for the redevelopment of lagging areas has recently been initiated but there is no agreement that Federal inducements will attract private capital to such areas. One view is that a decline in economic activity in these areas is inevitable and should be encouraged since this would strengthen the national economy. The opposite theory is that most distressed areas can overcome their competitive disadvantages and contribute to a faster growth in national output provided they are given short-term Federal assistance. Neither theory seems to be wholly valid. There are sound economic and social grounds for subsidizing the growth of employment in lagging areas in the short run. But for long-term assistance, the Federal Government should accept that it has inadequate resources to revitalize all distressed areas and should therefore concentrate its renewal efforts upon areas which have a high potential for redevelopment.
