Determining suitable investment areas using multi‐variable statistical methods: evidence from the Black Sea region in Turkey

Investment is an important decision for economic development, balanced growth and public welfare. There are many factors influencing investment. Thus, investment must be evaluated with multidimensional methods. Using taxonomy and principal component analysis this study attempts to determine appropriate investment areas in planned provinces in the Black Sea Region. Analyses were based on a number of demographic, economic, health, education, employment and cultural indicators. Results indicated that provinces were grouped into four clusters. Gümü?hane and Bayburt were determined to have the highest priority for investment in the manufacturing industry.     

Pricing, Capacity Choice, and Financing in Transportation Networks

Abstract.  This paper explores interrelations between pricing, capacity choice, and financing in transportation networks. We build on the Mohring‐Harwitz result on self‐financing of optimally designed and priced roads and investigate it in a network environment under various types of second‐best regulation. A small network model with endogenous car ownership demonstrates that optimal congestion pricing and capacity choice over an entire network may cause user prices to increase more in initially mildly congested areas compared to heavily congested areas. Furthermore, a flat kilometer charge under optimal capacity choice may result in first‐best efficiency gains.     

里耶秦简《祠律》考述

里耶秦简中有<祠律>及秦迁陵县祭祀先农等神祇的记载,为了解秦的宗教信仰及宗教管制政策提供了珍贵材料,也反映出当时宗教祭祀仪式已是中央及地方行政的组成部分,是各级官员的法定职责及义务.据此还可确定睡虎地秦简<法律答问>中有关宗教祭祀的解释应是对秦<祠律>条文的解释.     

Hierarchical Integration: The Dollar Economy and the Rupee Economy

While contemporary globalization makes the world more interconnected, it also reworks and builds on existing cleavages and uneven development. This is an under‐researched dimension of the emerging twenty‐first century international division of labour. The core question is whether new developments (associated with exports, offshoring and outsourcing) spin off to the majority in the countryside and the urban poor. This article examines the relationship between the dollar economy and the rupee economy in India. It documents the ways in which inequality is built into and sustains India's development. The authors discuss other instances of multi‐speed economies and analytics that seek to come to grips with these relations, from combined and uneven development to global value chains. They present three ways of capturing contemporary inequality: asymmetric inclusion, enlargement‐and‐containment and hierarchical integration, each of which captures different dimensions of inequality.     

SOCIAL NETWORKS AND THE CONVERGENCE OF POPULATION ATTRIBUTES: A GENERALIZATION

ABSTRACT.  Analysis of social interactions has recently become an important area of economic research, and the focus of researchers in this area has increasingly shifted toward dynamic models. In one recent contribution, Brueckner and Smirnov (2007) analyze the evolution of population attributes in an exceedingly simple model, where an agent's attributes at time t are equal to the average attribute value among his acquaintances. The pattern of acquaintances in the population is determined by the social network, and Brueckner and Smirnov (BS) explore the effect of network characteristics on the convergence of population attributes over time. They show that some simple sufficient conditions on the network structure ensure convergence to a "melting-pot" equilibrium where attributes are uniform across agents. The present paper provides a generalization of BS's analysis, allowing for a more general form of the rule governing the evolution of population attributes. The analysis shows that BS's previous conclusions continue to hold under this generalization, while also providing a result that can be applied more generally to other models.     

Geodateninfrastrukturen in der Praxis

Geodateninfrastrukturen sollen den Zugang zu und die Nutzung von Geoinformationen besser und effektiver gestalten und dadurch den einen Markt für Geoinformationen etablieren, in dem sowohl Massendaten, wie auch spezielle Informationen im Sinne problemspezifischer Auskünfte nachgefragt und im Idealfall auch abgerechnet werden k?nnen. Auf verschiedenen Organisationsstufen und in unterschiedlichen fachlichen Zusammenh?ngen werden zur Zeit internetbasierte Geodateninfrastrukturen (GDI) aufgebaut. Sie orientieren sich an den internationalen Standards des Open GIS Consortium (OGC) und der Internationalen Standardisierungsorganisation (ISO). Eine wichtige Voraussetzung für das Gelingen der Initiativen ist, da? sie nicht nur Top-Down von staatlichen Instanzen eingerichtet und betrieben werden, sondern auch Elemente kooperierender Bottom-Up-Entwicklung enthalten und vor allem alle potentiellen Nutzer einer GDI, von Datenanbietern über -veredlern und Software-Herstellern bis hin zu Endkunden, einbeziehen. Der Beitrag stellt den aktuellen Stand der Entwicklung und wichtige aktuelle Beispiele in der Praxis dar.
