Institutional Aspects of Regional Policy: The Impact of Centralized vs. Decentralized Responsibilities in the Field of Regional Policy on Economic Efficiency and Interregional Cohesion

Regional policy has – in general – the intention to supporting the efforts of regions with development problems to overcome their current problems and to stimulate an increase in regional economic growth. If the regional policy measures by a jurisdiction are successful, there will be a tendency towards more economic convergence between the various regions within that jurisdiction, with the result of a higher degree of cohesion between these regions, than in a state without regional policy. There are many studies on evaluating the impact of different instruments of regional policy on cohesion. But there are only few investigations so far into the institutional framework of these instruments. One institutional aspect has become more and more relevant in public discussions during the last few years: In federations (e. g. in the EU), there is in general not only one jurisdiction responsible for regional policy, but two, three or even more levels of government; the responsibilities (or: competences) are fragmentated between these levels. The paper presents a theoretical analysis of the impact of the allocation of competences in the field of regional policy on the outcome (interregional cohesion) and on the costs (economic efficiency) of regional policy. The analysis is based on the Theory of Fiscal Federalism, including the Economic Theory of Intergovernmental Grants. All the possible more central or more decentral arrangements of regional policy are located between two polar cases: At one pole, we have an arrangement where only the central level of government (e. g. the EU level) is responsible for regional policy; neither any subcentral unit of government (e. g. at the member state level in the EU), nor the regions which are to be supported (the less developed regions) have any influence for deciding on the implementation of regional policy instruments, and only the central government has to finance regional policy with its own resources. At the other pole, we find an arrangement where only the subcentral units of government and the less developed regions themselves are deciding on regional policy and are responsible for financing. In connection with financing, different categories of grants in aid may be applied. In addition, the arrangements may differ from each other because of different institutions for controlling the activities of the lower levels. The main hypothesis is, that a more decentralized institutional arrangement is not in general more efficient and effective than a more centralized arrangement; but – as compared to the status quo in Europe – a more decentralized arrangement for some public responsibilities would lead to better results in the field of regional policy. Central questions to be answered are: Have subcentral governments (as compared to central units of government) a tendency for neglecting their subregions with development problems? What is the impact of information costs and asymmetrical information on the choice of the level of government for certain (sub-) responsibilities? To which degree is the central influence stimulating – or: paralyzing – the initiative of the regions which are to be supported?

Partial orders on partial isometries

This paper studies three natural pre-orders of increasing generality on the set of all completely non-unitary partial isometries with equal defect indices. We show that the problem of determining when one partial isometry is less than another with respect to these pre-orders is equivalent to the existence of a bounded (or isometric) multiplier between two natural reproducing kernel Hilbert spaces of analytic functions. For large classes of partial isometries these spaces can be realized as the well-known model subspaces and deBranges-Rovnyak spaces. This characterization is applied to investigate properties of these pre-orders and the equivalence classes they generate.Comment: 30 pages. To appear in Journal of Operator Theor

The Life of a Vortex Knot

The idea that the knottedness (hydrodynamic Helicity) of a fluid flow is conserved has a long history in fluid mechanics. The quintessential example of a knotted flow is a knotted vortex filament, however, owing to experimental difficulties, it has not been possible until recently to directly generate knotted vortices in real fluids. Using 3D printed hydrofoils and high-speed laser scanning tomography, we generate vortex knots and links and measure their subsequent evolution. In both cases, we find that the vortices deform and stretch until a series of vortex reconnections occurs, eventually resulting several disjoint vortex rings. This article accompanies a fluid dynamics video entered into the Gallery of Fluid Motion at the 66th Annual Meeting of the APS Division of Fluid Dynamics.Comment: Videos are included; this submission is part of the DFD Gallery of Fluid Motio

Is There a Way for Old Industrial Districts to Become Attractive for Cultural Industry? The Case of Media Businesses in Halle (Saale), Germany

manufacturing have collapsed are trying to stimulate entrepreneurial activities of businesses in the cultural industry. The question is whether this strategy could be successful. This article examines the strategy of supporting the sector of Media Industry (´MI´) by policy makers in the region of Halle in East Germany, where a strong de-industrialization has taken place after the German reunification. Stimulated by the policy makers’ support measures, there actually was a remarkable development of MI. However, the number of MI firms and their employees did not further increase in recent years, after having reached a certain level. This illustrates the limits of political measures for turning a city’s path of industrial development voluntarily.media industry, cultural industry, business development, urban development, location factors

Experimental constraints on the polarizabilities of the 6s^2 1S0 and 6s6p 3P0 states of Yb

We utilize accurate experimental data available in the literature to yield bounds on the polarizabilities of the ground and first excited states of atomic Yb. For the 6s^2 1S0 ground state, we find the polarizability alpha to be constrained to 134.4<alpha<144.2 in atomic units, while for the 6s6p 3P0 excited state we find 280.1<alpha<289.9. The uncertainty in each of these values is 1.0. These constraints provide a valuable check for ab initio and semi-empirical methods used to compute polarizabilities and other related properties in Yb.Comment: 7 pages, 1 figur
