The Sources of Support for Separatism: Public Opinion in Three Soviet Republics

Abstract. The replacement of the Soviet Union by independent states rather than by a loose confederation of component republics reflects (in part) the demands for change that were being expressed by mass publics. What caused the people to reject decentralisation of authority within the existing state structure and chose rather to support movements that insisted on the establishment of independent states? We examine whether concerns about ‘discriminatory redistribution’ and ‘cultural preservation’ were more important than questions of ‘efficiency’ or ‘relative deprivation’ as motivations behind support for secession. The analysis is based upon public opinion data from Russia, Ukraine and Lithuania gathered in May of 1990 and in June of 1991. We conclude that although issues related to cultural preservation and discriminatory redistribution were foremost in the minds of separatists, concerns about efficiency and improved management in government are also relevant for understanding support for separatism.     

PRICING POLICY REACTIONS TO AGGLOMERATION IN A MARKET WITH SPATIAL SEARCH*

ABSTRACT. Price dispersion (variation) and agglomeration are common characteristics of spatial markets, in particular, markets with imperfect consumer information and search. However, pricing and location strategies in these markets are not well analyzed since spatial search is difficult to model without restricting the spatial dimension of the problem. This paper analyzes pricing and location strategies in a market with spatid search using a probabilistic modeling strategy that does not restrict search patterns in the plane. Specifically, the analysis considers the pricing strategy of an isolated firm in response to the agglomeration of competing firms. Results indicate that spatial and temporal price dispersion are effective responses to competitors'agglomeration. However, the relative effectiveness of these strategies varies with market conditions. In addition, agglomeration can have some counterintuitive effects. This paper also provides insights into existing theories of spatial search and spatial competition in spatially-restricted (linear and circular) markets.     

UPPER BOUNDS ON THE SIZES OF INTERREGIONAL FEEDBACKS IN MULTIREGIONAL INPUT-OUTPUT MODELS*

ABSTRACT. Upper bounds are presented for a measure of the overall percentage error caused in a multiregional input-output model when interregional feedback effects are ignored. This error figure is thus a measure of the magnitude of interregional linkages. The upper bounds are expressed as a function of the levels of self-sufficiency in the regions in the model and of the norms of the regional technical coefficients matrices. Experimental results are presented for a variety of examples that are thought to reflect real-world situations, and it is clear that in many cases the upper bound (and hence the error) is extremely small. The implication is that single-region input-output models may be adequate for a variety of questions.
