Abstract
Das im September 2012 auf Initiative der damaligen Abteilung Stadtökonomik gestartete Projekt zur Anbahnung gemeinsamer Forschungsarbeiten des Leontief Centre St. Petersburg (LC) und des IWH zu Fragen der wirtschaftlichen Neupositionierung post-sozialistischer Städte fand am 25. und 26. Februar 2015 mit einem Workshop in Halle (Saale) seinen vorläufigen Abschluss. Neben den beteiligten Mitarbeiterinnen und Mitarbeitern des LC und des IWH nahmen auch Wissenschaftlerinnen und Wissenschaftler anderer Forschungseinrichtungen teil, deren Forschung Bezüge zur Fragestellung des vom Bundesministerium für Bildung und Forschung (BMBF) geförderten Projekts aufweist. In den vorangehenden zweieinhalb Jahren gab es einen intensiven Austausch zwischen beiden Instituten u. a. in Form von Gastaufenthalten, gegenseitiger Hilfe bei der Datenbeschaffung und aufbereitung und gemeinsamen Auftritten bei wissenschaftlichen Veranstaltungen. Im Rahmen des Abschlussworkshops wurden Ergebnisse der gemeinsamen Arbeit wie auch thematisch verwandter Untersuchungen vorgetragen und diskutiert.

Plant-based Bioeconomy in Central Germany - Mapping of Actors, Industries and Places
Wilfried Ehrenfeld, Frieder Kropfhäußer
Abstract
The challenges facing the 21st century, presented by a growing global population, range from food security to sustainable energy supplies to the diminishing availability of fossil raw materials. An attempt to solve these problems is made by using the concept of bioeconomy. Plants, in particular, possess an important function in this context - they can be used either as a source of food or, in the form of biomass, for industrial or energy purposes. Linking industrial and agricultural research and production, bioeconomy provides growth potential, in particular in rural areas.
The aim of this article is therefore to outline the status of plant-based bioeconomy
in three states of Central Germany - Saxony, Saxony-Anhalt and Thuringia - and to compare this to German plant-based bioeconomy. We take an in-depth look at the different sectors and outline the industries involved, the location and age of the enterprises as well as the distribution of important NACE codes. In conclusion, we highlight the significant number of new or small enterprises and the high research and innovation rate of Central Germany. We also stress the future potential of Central German plant-based bioeconomy as well as the importance of a more plant-focusedview of the technology sector.

Is More Finance Better? Disentangling Intermediation and Size Effects of Financial Systems
Thorsten Beck, Hans Degryse, Christiane Kneer
Journal of Financial Stability,
2014
Abstract
Financial systems all over the world have grown dramatically over recent decades. But is more finance necessarily better? And what concept of financial system – a focus on its size, including both intermediation and other auxiliary “non-intermediation” activities, or a focus on traditional intermediation activity – is relevant for its impact on real sector outcomes? This paper assesses the relationship between the size of the financial system and intermediation, on the one hand, and GDP per capita growth and growth volatility, on the other hand. Based on a sample of 77 countries for the period 1980–2007, we find that intermediation activities increase growth and reduce volatility in the long run. An expansion of the financial sectors along other dimensions has no long-run effect on real sector outcomes. Over shorter time horizons a large financial sector stimulates growth at the cost of higher volatility in high-income countries. Intermediation activities stabilize the economy in the medium run especially in low-income countries. As this is an initial exploration of the link between financial system indicators and growth and volatility, we focus on OLS regressions, leaving issues of endogeneity and omitted variable biases for future research.

Note on the Hidden Risk of Inflation
Makram El-Shagi, Sebastian Giesen
Journal of Economic Policy Reform,
Nr. 1,
2014
Abstract
The continued expansionary policy of the Federal Reserve gives rise to speculation whether the Fed will be able to maintain price stability in the coming decades. Most of the scientific work relating money to prices relies on broad monetary aggregates (i.e. M2 for the United States). In our paper, we argue that this view falls short. The historically unique monetary expansion has not yet fully reached M2. Using a cointegration approach, we aim to show the hidden risks for the future development of M2 and correspondingly prices. In a simulation analysis we show that even if the multiplier remains substantially below its pre-crisis level, M2 will exceed its current growth path with a probability of 95%.

Efficiency in the UK Commercial Property Market: A Long-run Perspective
Steven Devaney, Oliver Holtemöller, R. Schulz
IWH Discussion Papers,
Nr. 15,
2012
Abstract
Informationally efficient prices are a necessary requirement for optimal resource allocation in the real estate market. Prices are informationally efficient if they reflect buildings’ benefit to marginal buyers, thereby taking account of all available information on future market development. Prices that do not reflect available information may lead to over- or undersupply if developers react to these inefficient prices. In this study, we examine the efficiency of the UK commercial property market and the interaction between prices, construction costs, and new supply. We collated a unique data set covering the years 1920 onwards, which we employ in our study. First, we assess if real estate prices were in accordance with present values, thereby testing for informational efficiency. By comparing prices and estimated present values, we can measure informational inefficiency. Second, we assess if developers reacted correctly to price signals. Development (or the lack thereof) should be triggered by deviations between present values and cost; if prices do not reflect present values, then they should have no impact on development decisions.

Macroeconomic Imbalances as Indicators for Debt Crises in Europe
Tobias Knedlik, Gregor von Schweinitz
Journal of Common Market Studies,
Nr. 5,
2012
Abstract
European authorities and scholars published proposals on which indicators of macroeconomic imbalances might be used to uncover risks for the sustainability of public debt in the European Union. We test the ability of four proposed sets of indicators to send early-warnings of debt crises using a signals approach for the study of indicators and the construction of composite indicators. We find that a broad composite indicator has the highest predictive power. This fact still holds true if equal weights are used for the construction of the composite indicator in order to reflect the uncertainty about the origin of future crises.

Intellectual Property Rights Policy, Competition and Innovation
Daron Acemoglu, Ufuk Akcigit
Journal of the European Economic Association,
Nr. 1,
2012
Abstract
To what extent and in what form should the intellectual property rights (IPR) of innovators be protected? Should a company with a large technology lead over its rivals receive the same IPR protection as a company with a more limited advantage? In this paper, we develop a dynamic framework for the study of the interactions between IPR and competition, in particular to understand the impact of such policies on future incentives. The economy consists of many industries and firms engaged in cumulative (step-by-step) innovation. IPR policy regulates whether followers in an industry can copy the technology of the leader. We prove the existence of a steady-state equilibrium and characterize some of its properties. We then quantitatively investigate the implications of different types of IPR policy on the equilibrium growth rate and welfare. The most important result from this exercise is that full patent protection is not optimal; instead, optimal policy involves state-dependent IPR protection, providing greater protection to technology leaders that are further ahead than those that are close to their followers. This is because of a trickle-down effect: providing greater protection to firms that are further ahead of their followers than a certain threshold increases the R&D incentives also for all technology leaders that are less advanced than this threshold.

A Macroeconomist’s View on EU Governance Reform: Why and How to Establish Policy Coordination?
Hubert Gabrisch
Economic Annals,
Nr. 191,
2011
Abstract
This paper discusses the need for macroeconomic policy coordination in the E(M)U. Coordination of national policies with cross-border effects does not exist at the macroeconomic level, although requested by the EU Treaty. The need for coordination stems from current account imbalances, which origin in market-induced capital flows, destabilizing the real exchange rates between low and high wage countries. The recent attempts of the Commission and the European Council to reform E(M)U governance do not address this problem and thus remain incapable to protect against future instability.
