INDUSTRIAL CENTERS AND REGIONAL GROWTH IN THE PRESENCE OF LOCAL INPUTS*

ABSTRACT. A large proportion of regional production takes place in nontraded goods and services. In addition, significant productivity increases can be observed in some segments of this sector. Starting from these two empirical observations we construct a model of growth in a two-region setting with factor mobility. The growth process is based on endogenous technological change in the nontraded input sector, whose output serves as an input in the production of one of the two final goods, the so-called industrial good. We consider two extreme cases, one with locally limited, the other with interregional knowledge spillovers. Conditions are established under which interior solutions with production of local inputs and steady-state growth in both regions result, and others under which we find a core-periphery pattern with growth concentrated in one region only. The stability of the equilibria is discussed by considering the transition processes. Finally, it is shown that catching-up as well as leapfrogging may occur, if new technologies become available.     

CHANGES IN THE NATURE OF URBAN SPATIAL STRUCTURE IN THE UNITED STATES, 1890–2000*

ABSTRACT This paper documents the long‐run trends in the average densities and density gradients of urban areas in the United States. The data show that between 1890 and 2000 the average densities of cities and metropolitan areas rose and fell but that the density gradients of urban areas generally declined monotonically over time. While it is beyond the scope of this paper to estimate the causes of these changes, this paper argues that a complete understanding of the changes in the nature of US urban spatial structures is likely to go beyond the standard explanations based on the monocentric city model such as decreases in transportation costs and increases in household incomes.     

INDUSTRIAL RESTRUCTURING IN A PERIOD OF CRISIS: AN ANALYSIS OF THE CANADIAN AUTOMOBILE INDUSTRY, 1973–83.*

The recent crisis in the North American economy is rooted in the disintegration of a particular model of capital accumulation known as Fordism. Using the empirical context of the auto industry in Canada the paper analyses the development and subsequent breakdown of Fordism and the forms taken by the restructuring which has occurred in response to the crisis.     

SHIPPING COSTS,INFORMATION COSTS,AND THE SOURCES OF INDUSTRIAL COAGGLOMERATION*

ABSTRACT Direct trade between establishments, coupled with costs of trading goods and information across space, has long been considered a primary determinant of industrial colocation. However, researchers have had difficulty decomposing the effects of interindustry trade into these two cost components. Using new techniques for separately estimating shipping and information costs, this paper provides an empirical framework for identifying the various sources of industrial coagglomeration among U.S. manufacturing industries. My findings suggest that both interindustry shipping costs and information costs influence metropolitan‐level coagglomeration. Additional evidence points to the significant role of direct information costs in determining intraindustry agglomerations.     

THE DETERMINANTS OF 1963–77 REGIONAL MANUFACTURING GROWTH: WHY THE SOUTH AND WEST GROW*

ABSTRACT. This paper analyzes 1963–77 manufacturing employment growth in the 48 contiguous states. Six factors jointly explain 96 percent of the variance. Markets explains 55 percent; climate, 15 percent; a rural state attraction, 11 percent; unionization, 6 percent; thresholds, 5 percent; and amenities, 4 percent. Resources, taxes, and business climate lack significance. Sunbelt-Frostbelt is a false dichotomy: the Northwest grew as fast as the South. The real contrast–largely caused by markets–is between growth rates of 6 percent in the Manufacturing Belt, 35 percent in its bordering Transition Zone, and 58 percent in the combined South and West.     

ESTIMATION OF THE AGE OF A PRE‐INDUSTRIAL IRON SITE IN KOREA*

A pre‐industrial iron‐smelting site in Korea, whose period of active use is placed on typological grounds between the eighth and 18th centuries ad , has been dated using accelerator mass spectrometry and thermoluminescence. The ages of two charcoal samples were 77 ± 25 and 81 ± 25 years bp , with the calibrated date for both ranging from ad 1700 to ad 1955, while a clay fragment dated to ad 1650 ± 50. The results from typology and radiocarbon seem insignificant due to the considerable uncertainties involved, but in combination with the thermoluminescence result they place the most probable date of the site at around ad 1700.     

TESTING THE NEW ECONOMIC GEOGRAPHY: MIGRATIONS AND INDUSTRIAL AGGLOMERATIONS IN SPAIN*

ABSTRACT This paper examines whether access to markets had a significant influence on migration choices of Spanish internal migrants in the interwar years. In it we perform a structural contrast of a New Economic Geography model that focuses on the forward linkage that links workers location choice with the geography of industrial production. The results prove the existence of a direct relation between workers' localization decisions and the market potential of the host regions. This could help to explain the apparently low intensity of internal migrations in Spain until the 1920s as well as its geography.
