Network evolution, success, and regional development in the European aerospace industry
(2014) Barber, Michael J.; Guffarth, Daniel
The success breeds success hypothesis has been mainly applied to theoretical network approaches. We investigate the European aerospace industry using data on the European Framework Programmes and on Airbus suppliers, focusing on the success breeds success hypothesis at four levels of analysis: the spatial structure of the European aerospace R&D collaboration network, its topological architecture, the individual actors that make up the network, and through a comparison of the Airbus invention and production networks. On the spatial level, SBS is favored: successful regions maintain their position and grow on a large scale, especially so for regions that have strongly participated from the very beginning. The regional hub structure is mirrored in the architecture of the European aerospace R&D collaboration network, where well-connected hub organizations play a key role in shaping the structure of the network through their many collaborative partnerships and do so in a way that strategically positions themselves with greater ability to access and regulate knowledge flows, as assessed by several centrality measures. Only successful organizations have the ability to form so many ties, with success thus breeding success in the European aerospace R&D collaboration network. The importance of the core organizations made clear through the centrality analysis is further supported by the analysis of weak ties, where we observe that the core organizations are connected to the rest of the network with many weak ties, thereby confirming their outstanding positions in the European aerospace R&D collaboration network as being able to access knowledge or other resources. With the combination of the R&D collaboration network and the Airbus production network on a spatial level, we see additional support for SBS, as those regions whose actors are frequent participants in both networks show the greatest share of successful actors. The European aerospace industry shows an ambidextrous character as a whole, which is nonetheless insufficient to avoid recent and future challenges demanding a strong emphasis on production skills.
Chinese urbanites and the preservation of rare species in remote parts of the country : the example of Eaglewood
(2014) Pelz, Sonna; Langenberger, Gerhard; Frör, Oliver; Ahlheim, Michael
Based on a Contingent Valuation study in Shanghai we assess peoples willingness to contribute personally to the alleviation of environmental problems occurring in distant parts of the country. One split of our survey assessed Shanghai residents willingness to pay for the preservation of rainforest in Yunnan, while the other split referred to the willingness to pay for the preservation of a single plant species (i.e. eaglewood) growing in this rainforest. The objectives of this study were twofold. Firstly, we wanted to find out if people living in big Chinese cities like Shanghai take an interest in the environmental problems existing in some remote parts of the country and if they are willing to contribute personally to remedy these problems. Secondly, we wanted to learn more about the motivation behind this kind of empathy, if it exists. We were especially interested in the question if this empathy refers to the specific environmental problems we addressed in our surveys or if it is motivated more by a general feeling of obligation towards environmental issues.
Varieties of knowledge-based bioeconomies
(2014) Pyka, Andreas; Urmetzer, Sophie
Governments around the world seek for strategies to overcome the reliance on fossil resources and provide solutions for the most challenging contemporary global issues: food shortage, depletion of natural resources, environmental degradation and climate change. A very recent and widely diffused proposition is to transform economic systems into bio-based economies, which are based on new ways of intelligent and efficient use of biological re-sources and processes. If taken seriously, such endeavour calls for the creation and diffusion of new knowledge as basis for innovation and behavioural change on various levels and therefore often is referred to as knowledge-based bioeconomy. In the current debate, the requirement for innovation is mostly seen in the advance of the biotechnology sector. How-ever, in order to fulfil the requirement of sustainability, which implicitly is connected with the bio-based economy, the transformation towards a bioeconomy requires a fundamental socio-economic transition and must comprise changes in technology as well as in markets, user practices, policy, culture and institutions. To illustrate a nation’s capability for this transition, we refer to the concept of national innovation systems in its broad approach. With the help of an indicator-based multivariate analysis we detect similarities and dissimilarities of different national systems within the European Union as basis for a transition towards a knowledge-based bioeconomy. The analysis allows to compare the different strategies and to identify bottlenecks as well as success factors and promising approaches in order to design policy instruments to foster this imperative transformation.
Outlier detection in structural time series models : the indicator saturation approach
(2014) Proietti, Tommaso; Marczak, Martyna
Structural change affects the estimation of economic signals, like the underlying growth rate or the seasonally adjusted series. An important issue, which has attracted a great deal of attention also in the seasonal adjustment literature, is its detection by an expert procedure. The general–to–specific approach to the detection of structural change, currently implemented in Autometrics via indicator saturation, has proven to be both practical and effective in the context of stationary dynamic regression models and unit–root autoregressions. By focusing on impulse– and step–indicator saturation, we investigate via Monte Carlo simulations how this approach performs for detecting additive outliers and level shifts in the analysis of nonstationary seasonal time series. The reference model is the basic structural model, featuring a local linear trend, possibly integrated of order two, stochastic seasonality and a stationary component. Further, we apply both kinds of indicator saturation to detect additive outliers and level shifts in the industrial production series in five European countries.
Maternal employment and childhood obesity in China : evidence from the China health and nutrition survey
(2014) Nie, Peng; Sousa-Poza, Alfonso
Subprime and euro crises : should we blame the economists?
(2013) Spahn, Peter
Economists in the public are accused of propagating highly professional, but unrealistic theories that mislead market agents and policy makers to place too much confidence in rational behaviour and market equilibrium. The paper analyses to what extent the US banking crisis and the euro crisis can be ascribed to fallacious assessments and recommendations on the part of economic theory. In the first case, myopic financial market theory and practice had neglected systemic repercussions of micro bank trading patterns. The euro crisis emerged from the neglect of undergraduate economic wisdom of necessary adjustment mechanisms in a currency union. Economists hopefully misinterpreted current account deficits as a sign of structural change.
Does medieval trade still mater? Historical trade centers, agglomeration and contemporary economic development
(2013) Wahl, Fabian
This study empirically establishes a link between medieval trade, agglomeration and contemporary regional development in ten European countries. It documents a statistically and economically significant positive relationship between prominent involvement in medieval trade and commercial activities and regional economic development today. Further empirical analyses show that medieval trade positively influenced city development both during the medieval period and in the long run; they also reveal a robust connection between medieval city growth and contemporary regional agglomeration and industry concentration. A mediation analysis indicates that a long-lasting effect of medieval trade on contemporary regional development is indeed transmitted via its effect on agglomeration and industry concentration. This research thus highlights the long-run importance of medieval trade in shaping the development of cities as well as the contemporary spatial distribution of economic activity throughout Europe. The path-dependent regional development processes caused by medieval commercial activities help explain the observed persistent regional development differences across the European countries considered.
Turkish-German innovation networks in the European research landscape
(2013) Heller-Schuh, Barbara; Pyka, Andreas; Prostolupow, Irene
Research networks are regarded as channels for knowledge creation and diffusion and are thus essential for the development and integration of economies. In this paper we have a look at the long Turkish-German-migration history which should offer opportunities for both countries to benefit from brain circulation, transnational entrepreneurs and research networks. The present paper examines the structure of research networks of the European Framework Programmes (FP) that are established by joint participation of organizations in research projects, in particular German research organizations with Turkish participants in FP5 to FP7 in the knowledge-intensive technology fields ICT, Biotechnology and Nanoscience. A better understanding of these networks allows for improving the design of research policies at national levels as well as at the EU level. The empirical examination of network properties reveals that the diverse networks show a range of similarities in the three technology fields in each FP such as the small-world properties. Moreover, our findings show that German actors play a specific role in most examined research networks with Turkish participation.
The success factors of technology-sourcing through mergers & acquisitions : an intuitive meta-analysis
(2013) Pyka, Andreas; Schön, Benjamin
With mergers & acquisitions playing an increasingly important role in today?s business world, academic research has strived to follow this trend by investigating their underlying causes and consequences. For a long time this research focused on the analysis of the financial effect of mergers & acquisitions as measured by market value or debt level. Thus, despite being a major vehicle of industry concentration and method of reallocation of resources, the technological impact of mergers & acquisitions remained comparatively underinvestigated for a long time. This, however, has changed in recent years. With the prevalence of the resource-based view and its derivates as the dominant logic in analysing today?s knowledge-intensive industries the focus shifted towards the technological aspects of mergers & acquisitions. With both mergers & acquisitions and innovation being centrepieces of competitive strategies in the modern economy, it is of central importance to understand the consequences of mergers & acquisitions for the innovative potential of firms. After more than twenty years of research in this field, it is time to take stock of what we know about the technological impact of mergers & acquisitions and its determinants. The aim of this paper is to provide an overview of the respective research by performing a meta-analysis of the empirical studies in the field. The intuitive setup allows for a detailed analysis of the individual determinants while differentiating between the impact on innovation input and output. We identify the knowledge characteristics of the partnering firms as being essential to the technological success of mergers & acquisitions. Important implications for policy makers, practitioners and future research are derived.
Migration and innovation : a survey
(2013) Pyka, Andreas; Rashidi, Sheida
In a world characterized by competition on a global scale, persistent structural change driven by innovation and aging societies in industrialized economies, also the competition for the best talents on the labour markets becomes global and more intensive. Therefore it is not surprising that old-fashioned brain drain explanations for migration are no longer convincing. In the knowledge-based economies of the 21st centuries the ideas of brain circulation and international (diaspora) innovation networks become prevailing and should guide the design of migration policies. This paper is a survey on the theoretical and empirical approaches which address the important relationship between migration and innovation.
Risiken aus Cloud-Computing-Services : Fragen des Risikomanagements und Aspekte der Versicherbarkeit
(2013) Hofmann, Annette; Haas, Andreas
Cloud-Computing services are changing the risk situation of IT-outsourcing and represent a challenge for the insurance industry. The most important problem to guarantee insurability of these emerging risks is that they are not stochastically independent. On the one hand, the interdependent network structure of these risks implies a significant contagion risk; on the other hand, new risks emerge that have not been addressed by existing (cyber risk) policies so far. Insurance concepts should be supported by innovative risk diversification concepts for cloud computing service. Addressing and classifying the new risks resulting from Cloud-Computing services, this article discusses insurability issues and risk management solutions.
Maternal employment and childhood obesity : a European perspective
(2013) Bammann, Karin; Williams, Garrath; Veidebaum, Toomas; Lauria, Fabio; Kovacs, Eva; Hadjigeorgiou, Charalampos; Fernandez-Alvira, Juan M.; Eiben, Gabriele; Henauw, Stefaan de; Ahrens, Wolfgang; Reisch, Lucia A.; Sousa-Poza, Alfonso; Gwozdz, Wencke
The substantial increase in female employment rates in Europe over the past two decades has often been linked in political and public rhetoric to negative effects on child development, including obesity. We analyse this association between maternal employment and childhood obesity using rich objective reports of various anthropometric and other measures of fatness from the IDEFICS study of children aged 2-9 in 16 regions of eight European countries. Based on such data as accelerometer measures and information from nutritional diaries, we also investigate the effects of maternal employment on obesity's main drivers: calorie intake and physical activity. Our analysis provides little evidence for any association between maternal employment and childhood obesity, diet or physical activity.
Capability-based governance patterns over the product life-cycle
(2013) Kok, A. G. de; La Poutré, J. A.; Pyka, Andreas; Vermeulen, B.
We investigate patterns of vertical governance over the product life-cycle as function of the capability regime properties imitability and substitutability. We use a novel neo-Schumpeterian model to study emerging governance patterns. We find that, in the era of incremental change, firms prefer vertical specialization. In the era of ferment, no governance form dominates. Imitability and substitutability, in interplay, determine the governance form preferred. High imitability frustrates appropriation and thereby integration for synergistic advantages. However, firms need not vertically specialize: under low substitutability, incompatibilities reduce the advantages of specialization. When both substitutability and imitability are low, firms can appropriate the value of their inventions and there is no combinatorial advantage of specialization, so firms predominantly integrate. If substitutability is high and imitability is low, the combinatorial advantage of specialization balances with the synergistic advantage of integration.
The evolution of innovation networks : the case of a German automotive network
(2013) Pyka, Andreas; Buchmann, Tobias
In this paper we outline a conceptual framework for depicting network development patterns of interfirm innovation networks and for analyzing the dynamic evolution of an R&D network in the German automotive industry. We test the drivers of evolutionary change processes of a network which is based on subsidised R&D projects in the 10 year period between 1998 and 2007. For this purpose a stochastic actor-based model is applied to estimate the impact of various drivers of network change. We test hypotheses in the innovation and evolutionary economics framework and show that structural positions of firms as well as actor covariates and dyadic covariates are influential determinants of network evolution.
Considering household size in contingent valuation studies
(2013) Schneider, Friedrich; Ahlheim, Michael
In many empirical Contingent Valuation studies one finds that household size, i. e. the number auf household members, is negatively correlated with stated household willingness to pay for the realization of environmental projects. This observation is rather puzzling because in larger households more people can benefit from an environmental improvement than in small households. Therefore, the overall benefit should be greater for larger households. A plausible explanation could be that household budgets are tighter for large families than for smaller families with the same overall family income. The fact that larger families can afford only smaller willingness to pay statements in Contingent Valuation surveys than smaller families with the same income and the same preferences might have consequences for the allocation of public funds whenever the realization of an environmental project is made dependent on the outcome of a Contingent Valuation study. In this paper we show how the use of household equivalence scales for the assessment of environmental projects with the Contingent Valuation Method can serve to reduce the discrimination of members of large families.
Corporate taxation and the quality of research and development
(2013) Riedel, Nadine; Richter, Katharina; Ernst, Christof
This paper examines the impact of tax incentives on corporate research and development (R&D) activity. Traditionally, R&D tax incentives have been provided in the form of special tax allowances and tax credits. In recent years, several countries moreover reduced their income tax rates on R&D output. Previous papers have shown that all three tax instruments are effective in raising the quantity of R&D related activity. We provide evidence that, beyond this quantity effect, corporate taxation also distorts the quality of R&D projects, i.e. their innovativeness and revenue potential. Using rich data on corporate patent applications to the European patent office, we find that a low tax rate on patent income is instrumental in attracting innovative projects with a high earnings potential and innovation level. The effect is statistically significant and economically relevant and prevails in a number of sensitivity checks. R&D tax credits and tax allowances are in turn not found to exert a statistically significant impact on project quality.
The impact of transfer pricing regulations on profit shifting within European multinationals
(2012) Lohse, Theresa; Riedel, Nadine
Over the past decade, several countries augmented their national tax law by transfer pricing legislations in order to limit opportunities for tax- motivated transfer price distortions and the associated relocation of multna- tional income from their borders. The aim of this paper is to empirically investigate the impact of transfer pricing laws on multinational profit shifting behaviour. To do so, we collect unique data on the evolution of national trans- fer price requirements in Europe over the past decade. This data is linked to accounting information on multinational firms in the EU and to corporate tax rate data. In line with previous studies, we find that multinational firms engage in significant tax-motivated profit shifting behaviour. The analysis fur- thermore suggests that transfer price documentation rules are instrumental in restricting income shifting activities. The effect is statistically significant and economically relevant. Our analysis thus underpins the benefits of im- plementing transfer price documentation requirements and suggests that they may be socially desirable despite the high administrative burden they impose on firms and tax authorities.
Political rights, taxation, and firm valuation : evidence from Saxony around 1900
(2012) Opitz, Alexander; Lehmann, Sibylle H.; Hauber, Philipp
The extension of the franchise to social groups with less property and income is associated with greater income redistribution from the rich to the poor and extension in the provision of public goods, which leads to the growth of government expenditure. All of these expected changes are costly and therefore a higher taxation of citizens and industrial firms can be expected, which might have negative effects on investors behavior. The present paper studies the effects of changes in the suffrage in the Kingdom of Saxony at the end of the 19th Century on stock market prices of Saxon firms listed on the Berlin stock exchange: Here the electoral law was changed twice: In 1896 a very restrictive franchise was introduced, which was abolished in 1909 and replaced by a more democratic electoral law. By applying standard event study methodology, we can provide evidence that the restriction of the electoral law had positive effects on Saxon firms on the stock market, where by the extension in 1909 had negative effects on the stock market.
Taking firms to the stock market : IPOs and the importance of large banks in imperial Germany 1896-1913
(2012) Lehmann, Sibylle H.
Large universal banks played a major role for Germany?s industrialisation because they provided loans to the industry and thereby helped firms to overcome liquidity constraints. Previous research has also argued that they were equally important on the German stock market. The present paper provides quantitative and qualitative evidence that although the market for underwriters was dominated by a small oligopoly of six large banks, there was still perceptible competition, which kept fees and short run profits low. Another interesting finding of the paper is the absence of a signalling effect to investors. Neither underpricing nor the one year performance was different for the IPOs issued by one of the Big Six. Thus, although the German IPO business was in the hands of a small oligopoly, investors did not benefit from the lack of competition. One explanation is that the quality of IPOs on the German stock market of the time was very good in general caused by the competition between underwriters, but also by the tight regulation of underwriting, which ensured the quality of all firms on the German stock market.
Fairness considerations in labor union wage setting : a theoretical analysis
(2012) Strifler, Matthias; Beißinger, Thomas
We consider a theoretical model in which unions not only take the outside option into account, but also base their wage-setting decisions on an internal reference, called the fairness reference. Wage and employment outcomes and the shape of the aggregate wagesetting curve depend on the weight and the size of the fairness reference relative to the outside option. If the fairness reference is relatively high compared to the outside option, higher wages and lower employment than in the standard model will prevail. If hit by an adverse technology shock, the economy will then react with a stronger downward adjustment in employment, whereas real wages are more rigid than in the standard model. With a low fairness reference the opposite results are obtained. An increase in the fairness weight amplifies the deviations of wages and employment from those of the standard model. It also leads to an increase in the degree of real wage rigidity if the fairness reference is high and an increase in the degree of real wage flexibility if the fairness reference is low. Thus, higher wages go hand in hand with more pronounced wage stickiness.
