We model on two different scales to analyse in how far downscaling leads to a different set of predictors to describe the realised habitat best. While the models on macroscale (grid of one square kilometre) cover the entire country, we select a set of smaller plots for modelling on territory scale. Whereas ring ouzels occur in altitudes above 1'000 m a.s.l. only, blackbirds occur from the lowlands up to the timber line. The altitudinal range overlap of the two species is up to 400 m. Despite both species coexist on macroscale, a direct niche overlap on territory scale is rare. Small-scale differences in vegetation cover and structure seem to play a dominant role for habitat selection. On macroscale however, we observe a high dependency on climatic variables mainly representing the altitudinal range and the related forest structure preferred by the two species. Applying the models for climate change scenarios, we predict a decline of suitable habitat for the ring ouzel with a simultaneous median altitudinal shift of +440 m until 2070. In contrast, the blackbird is predicted to benefit from higher temperatures and expand its range to higher elevations.}, language = {en} } @techreport{Gruševaja2006, type = {Working Paper}, author = {Gruševaja, Marina}, title = {Do institutions matter?}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-14485}, year = {2006}, abstract = {Contens 1 Introduction 2 Institutions and the Institutional Change 2.1 Institutions and Theoretical Concepts in Economics 2.2 Path Dependence 2.3 Inconsistence of Institutional Development 2.4 Determinants of Effectiveness 2.5 Efficiency of New Institutions 3 What is "Competition Policy"? 4 The Competition Policy in Russia as an Institution 4.1 Establishment of the Competition Policy as an Institution 4.2 Market Structure and Competition Policy 4.3 Measures of Competition Policy 4.3.1 Prohibition of Competition Restrictive Agreements or Concerted Actions 4.3.2 Abuse of Dominance 4.3.3 Merger Control 4.3.4 Restrictive Action to Competition of Administrative Bodies 4.4 Violations of the Competition Law 4.5 Problems of the Russian Competition Policy 5 Which Mistakes Russia has made with the Implementation of theCompetition Policy? 6 Is a Lacking Effectiveness of Transplanted Institutions Inevitable? 7 Concluding Remarks}, language = {en} } @techreport{BlienSanner2006, type = {Working Paper}, author = {Blien, Uwe and Sanner, Helge}, title = {Structural change and regional employment dynamics}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-14425}, year = {2006}, abstract = {A casual look at regional unemployment rates reveals that there are vast differences, which cannot be explained by different institutional settings. Our paper attempts to trace these differences in the labor market performance back to the regions' specialization in products that are more or less advanced in their product cycle. The model we develop shows how individual profit and utility maximization endogenously yields higher employment levels in the beginning. In later phases, however, employment decreases in the presence of process innovation. Our model suggests that the only way to escape from this vicious circle is to specialize in products that are at the beginning of their "economic life".

With regard to the famous three sector hypothesis, broad economic sectors were formed as required by this theory. The computation of their shares at GNP at market prices using Input-Output tables, and the adjustment of results from distortions, generated as side effects of tax avoidance practices, shows results that clearly reject claims that Russia would be on the road to a post-industrial service economy. Instead, at least until 2001, a tendency of "primarisation" could be observed, that presents Russia closer to less-developed countries.}, language = {en} } @techreport{Sanner2005, type = {Working Paper}, author = {Sanner, Helge}, title = {Instability in competition}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-14299}, year = {2005}, abstract = {In this paper we show that Puu (2002) does not provide a stable solution to the location game, according to his own definition of stability.

Even though this procedure is most common in analyzing Hotelling's location problem, it is not satisfying because it exhibits an inconsistent informational structure.

At first, border length is founded as a criterion of optimality. Secondly, it is shown that mixed patterns of concentric and wedge-shaped areas represent multiple equilibria if more than two groups of households are being considered. The welfare optimal segregated pattern depends on the relative purchasing power of different household groups.}, language = {en} }
