We explore the network topology arising from a dataset of the overnight interbank transactions on the e-MID trading platform from January 1999 to December 2010. In order to shed light on the hierarchical structure of the banking system, we estimate different versions of a core-periphery model....

Regional labor markets are characterized by huge disparities of unemployment rates. Models of the New Economic Geography explain how disparities of regional goods markets endogenously arise but usually assume full employment. This paper discusses regional unemployment disparities by introducing...

China's Hukou system poses severe restrictions on labor mobility. This paper assesses the consequences of relaxing these restrictions for China's internal economic geography. We base our analysis on a new economic geography model. First, we obtain estimates of the important model parameters on...

This paper provides evidence that interbank markets are tiered rather than flat, in the sense that most banks do not lend to each other directly but through money center banks acting as intermediaries. We capture the concept of tiering by developing a core-periphery model, and devise a procedure...

Processes of social opinion formation might be dominated by a set of highly influential agents acting as 'opinion leaders'. Here we explore whether such a perspective could shed light on the dynamics of a well known economic sentiment index. To this end, we hypothesize that the respondents of...

Despite the increasing and newly inspired interests in geographical economics and industry location theory, the majority of existing New Economic Geography models ignores the interdependence between spatial concentration, knowledge diffusion, invention and growth. For this reason, the paper...

This paper analyzes subsidies for intracity and intercity commuting in an urban economics framework with two cities and agglomeration externalities, where workers may commute within and between cities. First, commuting subsidies serve to internalize agglomeration externalities: Intracity...

This paper discusses a model of the New Economic Geography, in which the seminal core-periphery model of Krugman (1991) is extended by endogenous research activities. Beyond the common anonymous consideration of R&D expenditures within fixed costs, this model introduces vertical product...

Staat und Staatlichkeit, also der Leviathan, präsentieren sich derzeit in sehr unterschiedlichen Ausprägungen, die in ebenso unterschiedlichen sozio-ökonomischen Strukturen eingebettet sind. Der Autor unterscheidet den zivilisierten Leviathan in der OECD-Welt als späte Phase des modernen...

In this paper, we compare two different representations of Framework Programs as affiliation network: 'One-mode networks' and 'Two-mode networks'. The aim of this article is to show that the choice of the representation has an impact on the analysis of the networks and on the results of the...

We extent a solvable version of the core-periphery agglomeration model to four countries located in two regions. The paper shows that there might still be a race to the bottom in capital income tax rates despite agglomeration rents earned by the mobile factor. We find that intra-regional tax...

Die Biotechnologie, identifiziert als eine der strategischen Zukunftstechnologien, ist gekennzeichnet durch eine hohe Forschungsintensität mit breiten Anwendungsfeldern. Nach einer seit 2001 andauernden Konsolidierungsphase steht die Branche gegenwärtig vor neuen Herausforderungen: der...

The core-periphery model by Krugman (1991) has two 'dramatic' implications: catastrophic agglomeration and locational hysteresis. We study this seminal model with CES instead of Cobb-Douglas upper tier preferences. This small generalization suffices to change these stark implications. For a wide...

We incorporate the now standard knowledge-capital model of multinational firms in a new economic geography setting. The theoretical predictions of our model suggest that unskilled labor mobility leads to less concentration of production than skilled labor mobility does. This is in line with...

Tax competition for a mobile factor is different in 'new economic geography set- tings' compared to standard tax competition models. The agglomeration rent which accrues to the mobile factor in the core region can be taxed. Moreover, a tax differential between the core and the periphery can be...

Tax competition for a mobile factor is different in 'new economic geography settings' compared to standard tax competition models. The agglomeration rent which accrues to the mobile factor in the core region can be taxed. Moreover, a tax differential between the core and the periphery can be...

New Economic Geography (NEG) has reached a theoretical consolidation while related empirical tests are still scarce. The present paper aims at providing some evidence on the validity of forces emphasised by NEG. The analysis starts from the nominal wage equation derived from the Krugman...

We study the impact of changing relative market access in an enlarged EU on the economies of incumbent Objective 1 regions. First, we track the impact of external opening on internal spatial configurations in a three-region economic geography model. External opening gives rise to potentially...

According to New Growth Theory one can not rely on the convergence mechanisms inherent in traditional neoclassical constant returns to scale models. Convergence as well as divergence is possible, in general, depending on the assumptions about technology, factor mobility and ease of knowledge...

This paper presents a simple Chamberlinian agglomeration model which, like the canonical core-periphery (CP) model, contains two agglomerative forces. However, in contrast to that model, the present model is analytically solvable. Moreover, the present model exhibits a 'supercritical pitchfork...

Using panel data on European regions and applying Analysis of Covariance, our study provides an empirical assessment of the relative importance of national, regional and spatial factors for explaining variations of productivity. Our analysis shows that initial economic conditions or...

The aim of this paper is to provide a new mechanism for the spatial mismatch hypothesis. Spatial mismatch can here be the result of optimizing behavior on the part of the labor market participants. In particular, the unemployed can choose low amounts of search and long-term unemployment if they...

Using entropy indices and associated bootstrap tests, we describe the distribution of economic sectors across Western European regions over the 1975-2000 period. We decompose geographic concentration into its within-country and between-country components. In addition, we estimate...

This paper tests a geography and growth model using regional data for Europe, the US, and Japan. We set up a standard geography and growth model with a poverty trap and derive a log-linearized growth equation that corresponds directly to a threshold regression technique in econometrics. In...

Im Zuge der Osterweiterung der Europäischen Union eröffnen sich für die Beitrittskandidatenländer gute Möglichkeiten, wirtschaftliche Aktivitäten aus Westeuropa und anderswo zu attrahieren und im Pro-Kopf-Einkommen aufzuholen. Der Aufholprozess der Beitrittsländer wird jedoch von...

One of the most prominent instruments of regional policy is to foster education and human capital formation in economically lagging regions. However, regional policy of this type can actually hurt instead of help the poor areas. The reason is that individual geographical mobility increases with...

This paper presents a simple, analytically solvable Chamberlinian agglomeration model. As in the canonical core-periphery (CP) model, two agglomerative forces are at work. However, the present model exhibits a 'pitchfork bifurcation' rather than the 'tomahawk bifurcation' of the CP model.

This paper analyses in the framework of a 2-region economic geography model the impact of transfers on agglomeration of economic activity. Two main results can be derived: First, subsidies to the activity of firms are more efficient to avoid agglomeration than subsidies to consumers (social...

This paper presents a simple framework in which the location and the growth rate of economic activities are endogenous and interact. We show that the nature of the equilibrium and of the relation between growth and location depends fundamentally on whether capital is assumed to be mobile (in...

In standard models of New Economic Geography the overall regional price index in the centre is lower than in the periphery, because trade in manufacturing imposes transportation costs whereas trade in agriculture is assumed to be costless. Since real world observations suggest higher overall...

Dieses Papier untersucht die regionalpolitischen Implikationen der Neuen Ökonomischen Geographie. Erstens werden der allgemeine Modellrahmen der Neuen Ökonomischen Geographie und eine für die Politikanalyse geeignete Modellvariante erläutert. Zweitens wird untersucht, ob regionale...

Observing regions, for instance in Europe, one may easily notice inequalities in the resources they devote to innovation activities and in the results they reach in terms of economic success. In this respect, it may be assumed at first glance that a hierarchy of regional environment could be...
