Urban Transport Expansions, Employment Decentralization, and the Spatial Scope of Agglomeration Economies
This paper investigates the relationships between urban highway construction and the decentralization of jobs and workers’ residential locations by industry between 1960 and 2000. Estimates indicate that highways cause significantly greater amounts of residential than job decentralization both overall and in each broad industry category. Identification of these treatment effects relies on exoge...
متن کاملThe magnitude and causes of agglomeration economies
Firms and workers are much more productive in large and dense urban environments. There is substantial evidence of such agglomeration economies based on three aproaches. First, on a clustering of production beyond what can be explained by chance or comparative advantage. Second, on spatial patterns in wages and rents. Third, on systematic variations in productivity with the urban environment. H...
متن کاملSpatial Concentration in The Irish Pharmaceutical Industry: The Role of Government Intervention and Agglomeration Economies
This paper examines the spatial pattern of the pharmaceutical industry in Ireland and in particular the drivers accounting for spatial concentration in the industry. 1 Spatial concentration indexes indicate a particularly high level of spatial concentration in one of the industry's sub-sectors, namely, drug substance production. This high level of concentration has been attributed to the operat...

مطالعات قبلی بازار بیمه را به صورت کلی در نظر می گرفتند اما در این مطالعه صنعت بیمه به عنوان متغیر مستفل به بیمه های زندگی و غیر زندگی شکسته شده و هم چنین بیمه های زندگی به رشته های مختلف بیمه ای که در بازار بیمه ایران سهم قابل توجهی دارند تقسیم میشود. با استفاده از روشهای اقتصاد سنجی داده های برای دوره های 48-89 از مراکز ملی داده جمع آوری شد سپس با تخمین مدل خود بازگشتی برداری همراه با تعدادی ...
15 صفحه اولOn the Contribution of Agglomeration Economies to the Spatial Concentration of U.s. Employment
Why does the level of economic activity vary so much across space? One reason given is “agglomeration economies,” meaning that a firm’s or household’s production costs (of market and home goods, respectively) are lower when production is carried out in close proximity to other firms and households. In this paper I explore, via a quantitative spatial macroeconomic model, the contribution of aggl...
