Market field structure and dynamics in industrial automation
(2009) Slowak, André P.
There is a research tradition in the economics of standards which addresses standards wars, antitrust concerns or positive externalities from standards. Recent research has also dealt with the process characteristics of standardisation, de facto standard-setting consortia and intellectual property concerns in the technology specification or implementation phase. Nonetheless, there are no studies which analyse capabilities, comparative industry dynamics or incentive structures sufficiently in the context of standard-setting. In my study, I address the characteristics of collaborative research and standard-setting as a new mode of deploying assets beyond motivations well-known from R&D consortia or market alliances. On the basis of a case study of a leading user organisation in the market for industrial automation technology, but also a descriptive network analysis of cross-community affiliations, I demonstrate that there must be a paradoxical relationship between cooperation and competition. More precisely, I explain how there can be a dual relationship between value creation and value capture respecting exploration and exploitation. My case study emphasises the dynamics between knowledge stocks (knowledge alignment, narrowing and deepening) produced by collaborative standard setting and innovation; it also sheds light on an evolutional relationship between the exploration of assets and use cases and each firm's exploitation activities in the market. I derive standard-setting capabilities from an empirical analysis of membership structures, policies and incumbent firm characteristics in selected, but leading, user organisations. The results are as follows: the market for industrial automation technology is characterised by collaboration on standards, high technology influences of other industries and network effects on standards. Further, system integrators play a decisive role in value creation in the customer-specific business case. Standard-setting activities appear to be loosely coupled to the products offered on the market. Core leaders in world standards in industrial automation own a variety of assets and they are affiliated to many standard-setting communities rather than exclusively committed to a few standards. Furthermore, their R&D ratios outperform those of peripheral members and experience in standard-setting processes can be assumed. Standard-setting communities specify common core concepts as the basis for the development of each member's proprietary products, complementary technologies and industrial services. From a knowledge-based perspective, the targeted disclosure of certain knowledge can be used to achieve high innovation returns through systemic products which add proprietary features to open standards. Finally, the interplay between exploitation and exploration respecting the deployment of standard-setting capabilities linked to cooperative, pre-competitive processes leads to an evolution in common technology owned and exploited by the standard-setting community as a particular kind of innovation ecosystem.
Mismatches between actual and preferred work time : empirical evidence of hours constraints in 21 countries
(2009) Otterbach, Steffen
This paper analyzes the discrepancy between actual and desired working hours in a multinational setting. Using the latest data of the International Social Survey Program (ISSP) with a focus on work orientations hours constraints in 21 heterogeneous countries are analyzed. One major finding is that hours constraints are interrelated with macroeconomic variables such as (i) unemployment rates, (ii) GDP per capita as a measure of welfare, (iii) average weekly work hours, and (iv) income inequality. A subsequent multivariate analysis reveals that, on both macro- and microlevels, sociodemographic variables like prosperity and income, high risk of unemployment, and working conditions play an important role in determining working hours constraints. The results further suggest that, with respect to working conditions, such constraints are also affected by gender issues.
New economic geography reloaded : localized knowledge spillovers and the geography of innovation
(2009) Christ, Julian P.
Despite the increasing and newly inspired interests in geographical economics and industry location theory, the majority of existing New Economic Geography models ignores the interdependence between spatial concentration, knowledge diffusion, invention and growth. For this reason, the paper exclusively surveys the emergence and development of New Economic Geography Growth models in the context of the existing geography of innovation literature. The first part of the paper contributes with a classification of first- and second-nature causes of agglomeration and clustering. This part will also discriminate between static and dynamic externalities. Therefore, the chapter particularly compiles the differences between urbanization and localization externalities, and MAR, Jacobian and Porter externalities. A second concern of the paper is to highlight the modeling peculiarities of New Economic Geography Growth models. Besides approaching the main differences and similarities between first- and second-generation NEG models, the paper additionally reviews and discloses complemental contributions to the geography of innovation literature in the course of time. For this purpose, the paper examines in a meta-study 61 empirical contributions, which are related to the knowledge production function, the concept of spatial dependence and knowledge spillovers. The meta-study is complemented by bibliometric research. The paper ultimately concludes that the empirical studies that are related to the concept of (localized) knowledge spillovers and spatial association have caused a fundamental upgrading of the New Economic Geography literature towards non-pecuniary externalities. Consequently, the paper shows that recently developed second-generation NEG models offer alternative backward and forward linkages, which similarly determine centripetal and centrifugal forces, circular causality and finally the geography of innovation.
Why blu-ray vs. HD-DVD is not VHS vs. Betamax : the co-evolution of standard-setting consortia
(2009) Christ, Julian P.; Slowak, André P.
Extensive research has been conducted on the economics of standards in the last three decades. To date, standard-setting studies emphasize a superior role of demand-side-driven technology diffusion; these contributions assume the evolution of a user-driven momentum and network externalities. We find that consumers wait for a dominant standard if they are unable to evaluate technological supremacy. Thus, supply-side-driven activities necessarily need to address an absence of demand-side technology adoption. Our paper focuses on Blu-ray vs. HD-DVD as an illustrative case of consortia standard wars. One central role of consortia is to coordinate strategic behavior between heterogeneous agents, e.g. incumbents, complementors (content providers) and others, but also to form a coalition against other standard candidates. More precisely, we argue that agents signal standard-setting war outcomes through consortia events. We depict the essential role of consortia structures for the recently determined standard war between the High-Definition disc specifications Blu-ray and HD-DVD. Therefore, the paper suggests that unique supply-side dynamics from consortia structures, consortia announcements and exclusive backing decisions of firms determined the standard-setting process in the Blu-ray vs. HD-DVD standard war. This study is based on the following data: movie releases and sales numbers, membership affiliation for structural consortia analysis, and an in-depth event study. A detailed comparison of the technological specifications of both standard specifications supports our argument that there was no technological supremacy of one standard candidate from a consumer-oriented usecase perspective. We furthermore clarify that content providers (complementors) such as movie studios and movie rental services feature a gate-keeping position in the Blu-ray vs. HD-DVD standard war. In the case of Blu-ray, film studios decided the standard war because the availability of movie releases, but not technological supremacy, made the standard attractive to consumers. Finally, we find that there is a co-evolution of the consortia in terms of membership dynamics. Particularly, firm allegiance of heterogeneous agents plays a crucial role.
Unemployment in an interdependent world
(2009) Felbermayr, Gabriel; Larch, Mario; Lechthaler, Wolfgang
We introduce search and matching unemployment into a model of trade with differentiated goods and heterogeneous firms. Countries may differ with respect to size, geographical location, and labor market institutions. Contrary to the literature, our single-sector perspective pays special attention to the role of income effects and shows that bad institutions in one country worsen labor market outcomes not only in that country but also in its trading partners. This spill-over effect is conditioned by trade costs and country size: smaller and/or more centrally located nations suffer less from inefficient policies at home and are more heavily affected from spill-overs abroad than larger and/or peripheral ones. We offer empirical evidence for a panel of 20 rich OECD countries. Carefully controlling for institutional features and for business cycle comovements between countries, we confirm our qualitative theoretical predictions. However, the magnitude of spill-over effects is larger in the data than in the theoretical model. We show that introducing real wage rigidity can remedy this problem.
Economic consequences of low fertility in Europe
(2010) Bloom, David E.; Sousa-Poza, Alfonso
This paper focuses on possible economic consequences of low fertility in Europe. It summarizes a selection of papers that were presented at a conference at the University of St. Gallen in April 2008. This introduction also reviews the history of falling fertility in Europe and the literature that explores its causes, its potential implications, and possible policy responses. It summarizes the evolution of thinking about the relationship between population growth and economic development, with attention to recent work on the mechanisms through which fertility decline can spur economic growth if the necessary supporting conditions are met. The paper also identifies some of the challenges of population aging that are associated with low fertility and suggests that there may be less reason for alarm than has been suggested by some observers.
Ökonomische Aspekte der Entlohnung und Regulierung unabhängiger Versicherungvermittler
(2010) Schiller, Jörg
The compensation and regulation of independent intermediaries is an important issue in insurance markets. With this respect, the profitability and importance of fee-for-service and commission compensation of intermediaries is lively discussed in academia and in the insurance industry. This paper summarizes economic rationales why and in which lines of business insurance companies sell their products via independent intermediaries. With this respect, it is analyzed how different forms of compensation affect important market functions of independent intermediaries. Finally, the economic impact of certain regulatory interventions, like a mandatory disclosure or a general ban of any commissions and the German ban for intermediaries to share commission with policyholders, on market efficiency is discussed.
Drinking and protecting - a market approach to the preservation of cork oak landscapes
(2010) Frör, Oliver; Ahlheim, Michael
With the availability of new techniques to close wine bottles avoiding the risk of ?corky? taste the tradition of closing wine bottles with cork stoppers is on the retreat. As a consequence the Mediterranea cork oak forests with their rich biodiversity are endangered since their cultivation is not profitable anymore. This paper explores the viability of a market approach to the preservation of these ecologically valuable landscapes. In an internet-based Contingent Valuation survey we assess wine consumers' willingness to pay a higher price for wine bottles closed with high-quality cork stoppers instead of buying wine with alternative stoppers in order to preserve the cork oak landscapes. We find that though many wine consumers have experience with tainted wine they are, nevertheless, willing to buy wine with (highquality) cork stoppers at higher prices. Their average WTP is, however, not sufficient to cover the additional costs of these stoppers. Thus, we propose a financing mix of market returns and government subsidies for preserving the cork oaks. As a precondition for this market approach to be successful bottles with high-quality cork stoppers must be clearly identifiable in the shops, and consumers must be informed about the ecological consequences of supporting the cork production.
Labour as a utility measure in contingent valuation studies : how good is it really?
(2010) Ahlheim, Michael; Frör, Oliver; Heinke, Antonia; Duc, Nguyen Minh; Van Dinh, Pham
The Contingent Valuation Method (CVM) aims at the assessment of people's willingness to pay (WTP) for a public project. The sum of the individual WTPs is interpreted as the social benefits of the project under consideration and compared to the project costs. If the benefits exceed the costs the project is recommended for realization. In very poor societies budgets are so tight that households cannot give up any part of their income, i.e. of their market consumption, in favour of a public project, so that their WTP for that project stated in a CVM interview has to be zero or close to zero. This leads to a severe discrimination against poor regions in the decision process on the allocation of public funds. Therefore, several authors suggest to use labour contributions to the realization of a public project instead of monetary contributions as a measure of people's WTP for that project. In this paper we show theoretically and empirically, based on a CVM study conducted in Vietnam, that labour is severely flawed as a measuring rod for individual utility so that CVM based on labour contributions does not provide a reliable and meaningful decision rule for the allocation of public projects.
The geography and co-location of european technology-specific co-inventorship networks
(2010) Christ, Julian P.
This paper contributes with empirical findings to European co-inventorship location and geographical coincidence of co-patenting networks. Based on EPO co-patenting information for the reference period 2000-2004, we analyze the spatial configuration of 44 technology-specific co-inventorship networks. European co-inventorship (co-patenting) activity is spatially linked to 1259 European NUTS3 units (EU25+CH+NO) and their NUTS1 regions by inventor location. We extract 7.135.117 EPO co-patenting linkages from our own relational database that makes use of the OECD RegPAT (2009) files. The matching between International Patent Classification (IPC) subclasses and 44 technology fields is based on the ISI-SPRU-OST-concordance. We confirm the hypothesis that the 44 co-inventorship networks differ in their overall size (nodes, linkages, self-loops) and that they are dominated by similar groupings of regions. The paper offers statistical evidence for the presence of highly localized European co-inventorship networks for all 44 technology fields, as the majority of linkages between NUTS3 units (counties and districts) are within the same NUTS1 regions. Accordingly, our findings helps to understand general presence of positive spatial autocorrelation in regional patent data. Our analysis explicitly accounts for different network centrality measures (betweenness, degree, eigenvector). Spearman rank correlation coefficients for all 44 technology fields confirm that most co-patenting networks co-locate in those regions that are central in several technology-specific co-patenting networks. These findings support the hypothesis that leading European regions are indeed multi-filed network nodes and that most research collaboration is taking place in dense co-patenting networks.
Foreign patenting in Germany, 1877 - 1932
(2010) Streb, Jochen; Degner, Harald
In this paper, we use both patents? individual life span and foreign patenting activities in Germany to identify the most valuable patents of the 21 most innovative countries (except for Germany) from the European Core, the European periphery and overseas between 1877 and 1932. Our empirical analysis reveals that important characteristics of the international distribution of foreign patents are time-invariant. In particular, the distribution of foreign patents across countries in the late nineteenth and early twentieth centuries was as highly skewed as it was in the late twentieth century ? and even dominated by the same major research economies. Our analysis suggests that firms? technological advantages were influenced both by exogenous local factors, such as the countries? resource endowment, and by endogenous factors, such as the national education and research system or the countries? actual stage of economic development.
Causes of persistent productivity differences in the West German states in the period from 1950 to 1990
(2011) Waidlein, Nicole
Since the Second World War the West German states show persistent differences in their standard of living. The explanation of the incomplete catching-up process within West Germany is of crucial interest. After identifying productivity as the major growth driving force, this paper investigates the main causes of productivity growth on the state level between 1950 and 1990. With the help of growth theories different determinants of productivity growth are identified. These are innovations, secondary and tertiary human capital, structural change, openness and institutions. Finally, the empirical analysis reveals that three of those determinants are able to explain the persistent differences in the regional productivity levels: innovations, tertiary human capital and structural change.
A behavioral macroeconomic model with endogenous boom-bust cycles and leverage dynamcis
(2011) Scheffknecht, Lukas; Geiger, Felix
We merge a financial market model with leverage-constrained, heterogeneous agents with a reduced-form version of the New-Keynesian standard model. Agents in both submodels are assumed to be boundedly rational. The financial market model produces endogenously arising boom-bust cycles. It is also capable to generate highly non-linear deleveraging processes, fire sales and ultimately a default scenario. Asset price booms are triggered via self-fulfilling prophecies. Asset price busts are induced by agents' choice of an increasingly fragile balance sheet structure during good times. Their vulnerability is inevitably revealed by small, randomly occurring shocks. Our transmission channel of financial market activity to the real sector embraces a recent strand of literature shedding light on the link between the active balance sheet management of financial market participants, the induced procyclical fluctuations of desired risk compensations and their final impact on the real economy. We show that a systematic central bank reaction on financial market developments dampens macroeconomic volatility considerably. Furthermore, restricting leverage in a countercyclical fashion limits the magnitude of financial cycles and hence their impact on the real economy.
Engel curves, spatial variation in prices and demand for commodities in Cote d'Ivoire
(2011) Sousa-Poza, Alfonso; Gbakou, Monnet Benoit Patrick
This paper aims to estimate the price and income elasticities of the demand for essential commodities in Cote d?Ivoire. Using data from the 2002 Cote d'Ivoire Living Standard Survey and a theoretical framework developed by Crawford et al. (2003), we analyse price effects on the demand for groups of commodities by exploiting a relationship between unit values and commodity quantities and deriving Engel curves. Our findings reveal that the own-price elasticity of meat and dairy products is considerably stronger for rich households (those in the 90th percentile of total expenditure) than for poor households (those in the 10th percentile of total expenditure). Although all the modelled groups of commodities are normal goods, the paper shows that starch is more of a necessity for poor households than for rich ones, whereas meat and dairy products are more of a luxury good for poor households than for rich households.
Work hours constraints and health
(2011) Sousa-Poza, Alfonso; Otterbach, Steffen; Bell, David
The issue of whether employees who work more hours than they want to suffer adverse health consequences is important not only at the individual level but also for governmental formation of work time policy. Our study investigates this question by analyzing the impact of the discrepancy between actual and desired work hours on self-perceived health outcomes in Germany and the United Kingdom. Based on nationally representative longitudinal data, our results show that work-hour mismatches (i.e., differences between actual and desired hours) have negative effects on workers´ health. In particular, we show that ?overemployment? ? working more hours than desired - has negative effects on different measures of self-perceived health.
Verhaltensmodell für Softwareagenten im Public Goods Game
(2011) Kirn, Stefan; Müller, Marcus; Stern, Guillaume; Jacob, Ansger
Gegenstand der vorliegenden Arbeit ist das Verhaltensmodell von Softwareagenten in einem Public Goods Game. Agenten im Sinne der Arbeit besitzen jeweils eigene, individuelle Ziele und müssen sich im Hinblick auf ein übergeordnetes Gesamtziel im Multiagentensystem koordinieren. Dabei hängen die individuell und kollektiv erzielbaren Ergebnisse von der Wahl der Verhaltensmodelle der Agenten ab. Die Wahl eines rein eigennützigen Verhaltens kann zu Nutzeneinbußen führen; die Wahl eines selbstlosen Verhaltens kann die individuell erzielbaren Ergebnisse eines Agenten massiv beeinträchtigen, falls andere Agenten im System eigennützig spielen. Die Auswirkungen verschiedener, aus der sozio-ökonomischen Theorie entlehnter Verhaltensmodelle in unterschiedlich gestalteten Agenten-Gesellschaften wird mittels einer Simulation untersucht. Die vorliegende Arbeit soll somit einen Beitrag liefern, um auf Basis deskriptiver sozio-ökonomischer Verhaltensmodelle Aussagen über das Verhalten von Softwareagenten (präskriptive Modelle) zu erlauben. Die Erkenntnisse helfen Entwicklern von Multiagentensystemen bei der Implementierung eines problemadäquaten Agentenverhaltens.
Anwendung des öffentlichen Vergaberechts auf moderne IT-Softwareentwicklungsverfahren
(2011) Kirn, Stefan; Müller-Hengstenberg, Claus D.
Die öffentliche Hand ist der größte Auftraggeber in Deutschland, Europa und wohl auch in anderen Ländern der Welt wie USA und England. Nach der ?International Market Scoreboard-Statistik July 2009? betrug das Gesamtvolum aller EU-weit ausgeschriebenen öffentlichen Aufträge 2 Billionen Euro. Damit besitzt die öffentliche Hand eine beträchtliche Marktmacht, die geeignet ist, massiven Einfluss auf die Wettbewerbsverhältnisse auf den Märkten zu nehmen. Angesichts dieser Gefahr für den Wettbewerb hat das öffentliche Vergaberecht (§§ 100 f GWB, VOB/A,VOL/A usw.) die Aufgabe, diese Marktmacht der öffentlichen Auftraggeber in Grenzen zu halten und den Wettbewerb auf den Beschaffungsmärkten zu schützen. Absolute Priorität der Vergabeordnungen (§ 101 GWB) hat daher die öffentlichen Vergabe im Wettbewerb. Besondere Vergabeprobleme zeigen sich immer wieder bei der öffentlichen Vergabe von IT Anwendungsentwicklungen. Hierbei werden aus betriebswirtschaftlichen Gründen zunehmend Technologiekonzepte (iterative Verfahren) verwandt, bei denen die wirtschaftlichen und technischen Ziele erst in Form eines iterativen Prozesses zwischen Anbieter und Kunde erarbeitet und realisiert werden. Der nachfolgende Beitrag gibt einen Überblick über die öffentlichen Vergabearten und behandelt die Frage, ob und in welcher Weise Software-Entwicklungsprozesse mit den Vergabearten der öffentlichen Hand in Einklang stehen oder gebracht werden können.
Asymmetric obligations
(2011) Schildberg-Hörisch, Hannah; Riedel, Nadine
We use a laboratory experiment to investigate the behavioral effects of obligations that are not backed by binding deterrent incentives. To implement such expressive law' we introduce different levels of very weakly incentivized, symmetric and asymmetric minimum contribution levels (obligations) in a repeated public goods experiment. The results provide evidence for a weak expressive function of law: while the initial impact of high obligations on behavior is strong, it decreases over time. Asymmetric obligations are as effective as symmetric ones. Our results are compatible with the argument that expressive law affects behavior by attaching an emotional cost of disobeying the own obligation.
Respondent incentives in contingent valuation : the role of reciprocity

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.
