Nr. 1,

Abstract
We apply a network perspective and study the emergence of core-periphery (CP) structures in innovation networks to shed some light on the relationship between isolation and innovation. It has been frequently argued that a firm’s location in a densely interconnected network area improves its ability to access information and absorb technological knowledge. This, in turn, enables a firm to generate new products and services at a higher rate compared to less integrated competitors. However, the importance of peripheral positions for innovation processes is still a widely neglected issue in literature. Isolation may provide unique conditions that induce innovations which otherwise may never have been invented. Such innovations have the potential to lay the ground for a firm’s pathway towards the network core, where the industry’s established technological knowledge is assumed to be located.
The aim of our paper is twofold. Firstly, we propose a new CP indicator and apply it to analyze the emergence of CP patterns in the German laser industry. We employ publicly funded Research and Development (R&D) cooperation project data over a period of more than two decades. Secondly, we explore the paths on which firms move from isolated positions towards the core (and vice versa). Our exploratory results open up a number of new research questions at the intersection between geography, economics and network research.

Returns to Skills around the World: Evidence from PIAAC
Eric A. Hanushek, Guido Schwerdt, Simon Wiederhold, Ludger Woessmann
European Economic Review,
January
2015
Abstract
Existing estimates of the labor-market returns to human capital give a distorted picture of the role of skills across different economies. International comparisons of earnings analyses rely almost exclusively on school attainment measures of human capital, and evidence incorporating direct measures of cognitive skills is mostly restricted to early-career workers in the United States. Analysis of the new PIAAC survey of adult skills over the full lifecycle in 23 countries shows that the focus on early-career earnings leads to underestimating the lifetime returns to skills by about one quarter. On average, a one-standard-deviation increase in numeracy skills is associated with an 18 percent wage increase among prime-age workers. But this masks considerable heterogeneity across countries. Eight countries, including all Nordic countries, have returns between 12 and 15 percent, while six are above 21 percent with the largest return being 28 percent in the United States. Estimates are remarkably robust to different earnings and skill measures, additional controls, and various subgroups. Instrumental-variable models that use skill variation stemming from school attainment, parental education, or compulsory-schooling laws provide even higher estimates. Intriguingly, returns to skills are systematically lower in countries with higher union density, stricter employment protection, and larger public-sector shares.

Interrelationship between Industrial and Innovation Development in East Germany
Gerhard Heimpold
Region: Ekonomika i Soziologija,
Nr. 2,
2015
Abstract
The article demonstrates that the most important reason for the slowdown and stagnation of economic convergence in East Germany is the weakness in terms of research and development and innovation. It analyzes the interrelationship between industrial and innovative development in the East German federal states since 1990. The article shows how the East German industry sector and its R&D activities looked like in the late 1980s and which transition it had undergone in the course of privatization. The industrial development of the new federal states after 1990 is analyzed. The paper reveals structural shortcomings in East Germany's economy and considers their impact on the progress in R&D.

Do We Need New Modelling Approaches in Macroeconomics?
Claudia M. Buch, Oliver Holtemöller
Financial Cycles and the Real Economy: Lessons for CESEE Countries,
2014
Abstract
The economic and financial crisis that emerged in 2008 also initiated an intense discussion on macroeconomic research and the role of economists in society. The debate focuses on three main issues. Firstly, it is argued that economists failed to predict the crisis and to design early warning systems. Secondly, it is claimed that economists use models of the macroeconomy which fail to integrate financial markets and which are inadequate to model large economic crises. Thirdly, the issue has been raised that economists invoke unrealistic assumptions concerning human behaviour by assuming that all agents are self-centred, rationally optimizing individuals. In this paper, we focus on the first two issues. Overall, our thrust is that the above statements are a caricature of modern economic theory and empirics. A rich field of research developed already before the crisis and picked up shortcomings of previous models.

Taxes, Banks and Financial Stability
Reint E. Gropp
R. de Mooij and G. Nicodème (eds), Taxation and Regulation of the Financial Sector. MIT Press,
2014
Abstract
In response to the financial crisis of 2008/2009, numerous new taxes on financial institutions have been discussed or implemented around the world. This paper discusses the connection between the incidence of the taxes, their incentive effects, and policy makers’ objectives. Combining basic insights from banking theory with standard models of tax incidence shows that the incidence of such taxes will disproportionately fall on small and medium size enterprises. The arguments presented suggest it is unlikely that the taxes will have a beneficial impact on financial stability or raise significant amounts of revenue without increasing the cost of capital to bank dependent firms significantly.

The Dynamics of Bank Spreads and Financial Structure
Reint E. Gropp, Christoffer Kok, J.-D. Lichtenberger
Quarterly Journal of Finance,
Nr. 4,
2014
Abstract
This paper investigates the effect of within banking sector competition and competition from financial markets on the dynamics of the transmission from monetary policy rates to retail bank interest rates in the euro area. We use a new dataset that permits analysis for disaggregated bank products. Using a difference-in-difference approach, we test whether development of financial markets and financial innovation speed up the pass through. We find that more developed markets for equity and corporate bonds result in a faster pass-through for those retail bank products directly competing with these markets. More developed markets for securitized assets and for interest rate derivatives also speed up the transmission. Further, we find relatively strong effects of competition within the banking sector across two different measures of competition. Overall, the evidence supports the idea that developed financial markets and competitive banking systems increase the effectiveness of monetary policy.

The Development of Cities and Municipalities in Central and Eastern Europe: Introduction for a Special Issue of 'Urban Research and Practice'
Martin T. W. Rosenfeld, Albrecht Kauffmann
Urban Research & Practice, Vol. 7 (3),
Nr. 3,
2014
Abstract
Since the 1990s, local governments in Central and Eastern European (CEE) countries have been confronted by completely new structures and developments. This came after more than 40 years (or even longer in the case of the former Soviet Union) under a socialist regime and behind an iron curtain which isolated them from the non-socialist world. A lack of resources had led to an underinvestment in the refurbishment of older buildings, while relatively cheap ‘prefabricated’ housing had been built, not only in the outskirts of cities, but also within city centres. A lack of resources had also resulted in the fact that the socialist regimes were generally unable to replace old buildings with ‘modern’ ones; hence, there is a very rich heritage of historical monuments in many of these cities today. The centrally planned economies and the development of urban structures (including the shifts of population between cities and regions) were determined by ideology, political rationality and the integration of all CEE countries into the production schemes of the Council for Mutual Economic Assistance and its division of labour by location. The sudden introduction of a market economy, private property, democratic rules, local autonomy for cities and municipalities and access to the global economy and society may be seen as a kind of ‘natural experiment’. How would these new conditions shape the national systems of cities and municipalities? Which cities would shrink and which would grow? How would the relationship between core cities and their surrounding municipalities develop? And what would happen within these cities and with their built environment?

The Impact of Local Factors on the Scope of Benefits from Public Investment: The Case of Tourism Infrastructure in Saxon Municipalities
Martin T. W. Rosenfeld, Albrecht Kauffmann
Urban Research & Practice,
Nr. 3,
2014
Abstract
Following the transition from socialist central planning economies to market economies in all of the former socialist countries, many regions have had to cope with severe structural changes and economic development problems. To overcome these problems, local governments have tried to invest in new public infrastructure to support the development of new industries. This paper looks at infrastructure that supports tourist activities and argues that the impact of infrastructure generally depends on certain local factors which differ between municipalities. One important factor is whether the local population possesses the relevant complementary factors, in particular the right ‘soft skills’.

The Euro Plus Pact: Cost Competitiveness and External Capital Flows in the EU Countries
Hubert Gabrisch, K. Staehr
Abstract
The Euro Plus Pact was approved by 23 EU countries in March 2011 and came into force shortly afterwards. The Pact stipulates a range of quantitative targets meant to strengthen cost competitiveness with the aim of preventing the accumulation of external financial imbalances. This paper uses Granger causality tests and vector autoregressive models to assess the short-term linkages between changes in the relative unit labour cost and changes in the current account balance. The sample consists of annual data for 27 EU countries for the period 1995-2012. The main finding is that changes in the current account balance precedes changes in relative unit labour costs, while there is no discernible effect in the opposite direction. The divergence in unit labour costs between the countries in Northern Europe and the countries in Southern and Eastern Europe may thus partly be the result of capital flows from the core of Europe to the periphery prior to the global financial crisis. The results also suggest that the measures in the Euro Plus Pact to restrain the growth of unit labour costs may not affect the current account balance in the short term.

The Role of Entrepreneurship in US Job Creation and Economic Dynamism

Journal of Economic Perspectives,
Nr. 3,
2014
Abstract
An optimal pace of business dynamics—encompassing the processes of entry, exit, expansion, and contraction—would balance the benefits of productivity and economic growth against the costs to firms and workers associated with reallocation of productive resources. It is difficult to prescribe what the optimal pace should be, but evidence accumulating from multiple datasets and methodologies suggests that the rate of business startups and the pace of employment dynamism in the US economy has fallen over recent decades and that this downward trend accelerated after 2000. A critical factor in accounting for the decline in business dynamics is a lower rate of business startups and the related decreasing role of dynamic young businesses in the economy. For example, the share of US employment accounted for by young firms has declined by almost 30 percent over the last 30 years. These trends suggest that incentives for entrepreneurs to start new firms in the United States have diminished over time. We do not identify all the factors underlying these trends in this paper but offer some clues based on the empirical patterns for specific sectors and geographic regions.
