Spatially Varying Relationships of New Firm Formation in the United States

Cheng S. and Li H. Spatially varying relationships of new firm formation in the United States, Regional Studies. This paper seeks to examine spatially varying relationships between new firm formation and its determinants across US counties. A geographically weighted regression (GWR) technique is calibrated with firm birth data in ten separate industries over the period 2001–2003. Results of GWR analysis support the existence of spatially varying relationships and show significant local variations, in magnitudes and/or signs, of new business creation in all the ten sectors investigated. The local variations were masked in traditional ordinary least-squares (OLS) global analysis. This paper is also intended to inform policy-makers and professionals about location-specific relationships and reject ‘one-size-fits-all’ public policies. Cheng S. et Li H. La variation géographique des rapports de la création des nouvelles entreprises aux Etats-Unis, Regional Studies. Cet article cherche à examiner la variation géographique des rapports entre la création des nouvelles entreprises et ses déterminants à travers les comtés des Etats-Unis. Une technique de régression géographiquement pondérée est calibrée avec des données sur la création d’entreprise pour ce qui est de dix industries différentes entre 2001 et 2003. Les résultats de l’analyse confirment la présence des rapports qui varient suivant l’emplacement géographique et qui démontrent des variations de la création d’entreprise dans tous les dix secteurs examinés, à la fois en importance et/ou en signes. Pour ce qui concerne la méthode des moindres carrés, les variations locales étaient voiles. Cet article cherche aussi à informer les décideurs et les professionnels des rapports spécifiques à un endroit donné et à repousser des politiques ‘uniformes’.

Räumlich variable Beziehungen von Firmengründungen in den USA, Regional Studies. In diesem Beitrag untersuchen wir räumlich variable Beziehungen zwischen Firmengründungen und ihren Determinanten in verschiedenen Bezirken der USA. Anhand der Daten von Firmengründungen in zehn verschiedenen Branchen im Zeitraum von 2001 bis 2003 wird eine geografisch gewichtete Regression (GWR) kalibriert. Die Ergebnisse der GWR-Analyse sprechen für die Existenz von räumlich variablen Beziehungen und weisen in allen zehn untersuchten Sektoren hinsichtlich des Umfangs und/oder der Anzeichen von Firmengründungen signifikante lokale Abweichungen auf. Bei einer herkömmlichen globalen OLS-Analyse bleiben diese lokalen Abweichungen verborgen. Mit diesem Beitrag sollen auch Politiker und Experten über standortspezifische Beziehungen informiert werden; gleichzeitig versteht sich der Beitrag als Kritik an pauschal gestalteten öffentlichen Politiken.

Relaciones que varían espacialmente en la formación de nuevas empresas en los Estados Unidos, Regional Studies. El objetivo de este artículo es analizar las relaciones que varían espacialmente entre la formación de nuevas empresas y sus determinantes en los diferentes condados de los Estados Unidos. Se calibra una técnica de regresiones ponderadas geográficamente (RPG) con los datos de nacimiento de las empresas en diez industrias por separado durante el periodo de 2001 a 2003. Los resultados del análisis de la regresión ponderada geográficamente apoyan la existencia de relaciones que varían espacialmente y muestran significantes variaciones locales, según magnitudes o signos, en la creación de nuevas empresas en los diez sectores investigados. Las variaciones locales fueron enmascaradas en el tradicional análisis global de la regresión por mínimos cuadrados ordinarios. Con este artículo también queremos informar a políticos y profesionales de las relaciones inherentes a la localización y rechazar la políticas públicas con un enfoque único.

Estimating the Economic Consequences of Terrorist Disruptions in the National Capital Region: An Application of Input-Output Analysis

This paper explores and demonstrates an innovative application of an input-output model for the assessment of the economic consequences of hypothetical disruption events. Such events in a region are first simulated and their affected areas estimated using a GIS-based geo-spatial simulation approach. Then, the consequences of the simulated events on the regional economy are estimated and disaggregated by industry and sub-region. The research is important because it develops a new simulation and input-output model approach to regional and national security analysis that offers promising results. Further, it provides a methodology for assessing the economic consequences of possible disruption events. Knowledge of economic impacts of disruptions is essential for determining and justifying appropriate protection and mitigation policies and measures.

Measuring and building high-quality entrepreneurship: a research prospectus

This article discusses a detailed research design to measure entrepreneurship quality, as opposed to entrepreneurship quantity, and to develop a standard entrepreneurship quality measure focusing on high-growth small and often new businesses, based on critiques of previous entrepreneurship measures. Available longitudinal establishment-level data sources for building up the entrepreneurship quality index are introduced and evaluated and the Longitudinal Business Database of the US Census Bureau emerges as the best candidate because of its coverage and timely update. The creation and development of the entrepreneurship quality measure will enable researchers to empirically identify a wide range of economic, social, policy, and firm factors that may affect the development of high-quality entrepreneurship. The creation and development of the entrepreneurship quality measure will also enable researchers to uncover the critical role of high-quality entrepreneurship in economic growth in general and in rural development in particular.

Strategic business planning in public safety: a case study of capital wireless integrated network

The focus of this paper is on the Capital Wireless Integrated Network (CapWIN) project, a wireless communication system that supports unit to unit communication for emergency services (police, fire and EMS) across multiple jurisdictions in the US National Capital Region. The paper presents elements of the business plan that was developed in an effort to build a consensus among regional officials and leaders on how to support the costs of operating CapWIN. This paper is of particular interest because it describes the application of the business plan concept to the development of a multi-jurisdictional government corporation seeking to operate in a business like manner.
