Government R&D Subsidies as a Signal for Private Investors

Government subsidies for R&D are intended to promote projects with high returns to society but too little private returns to be beneficial for private investors. This may be caused by spillovers or a low appropriability rate. Apart from the direct funding of these projects, government grants may serve as a signal for good investments for private investors. We use a simple signaling model with different types of R&D projects to capture this phenomenon. In a setup where the subsidy can only be used to distinguish between high and low risk projects, government agency’s signal is not very helpful for banks. However, if the subsidy is accompanied by a quality signal, it can lead to increased or better selected private investments.Subsidies, Innovation, Asymmetric Information, Signaling

The Effect of Mergers on the Incentive to Invest in Cost Reducing Innovations

Both mergers and innovation are central elements of a firm?s competitive strategy. However, model-theoretical analyses of the merger-innovation link is sparse. The aim of this paper is to analyze the impact of mergers on innovative activities and product market competition in the context of incremental process innovations. Inefficiencies due to organizational problems of mergers are accounted for. We show that optimal investment strategies depend on the resulting market structure and differ significantly from insider to outsider. In our linear model mergers turn out to increase social surplus. --Horizontal mergers,innovation,research joint venture,market structure

Predicting the future of additive manufacturing: A Delphi study on economic and societal implications of 3D printing for 2030

Additive manufacturing (colloquially: 3D printing) is a highly discussed topic. Previous research has argued that this technology not only has profound effects on manufacturing businesses but also on society, which demands new corporate strategies and policies alike. Thus, the development of reliable future scenarios is key for strategic planning and decision making as well as for future research. Dedicated academic studies in this field remain scarce. We present the results of an extensive Delphi survey on the future of additive manufacturing with a focus on its economic and societal implications in 2030. Via an initial round of extensive qualitative interviews and a Delphi-based analysis of 3510 quantitative estimations and 1172 qualitative comments from 65 experts, we were able to develop and validate 18 projections that were then clustered into a scenario for the most probable future. The scenario is built on the six Delphi projections with the highest consensus on the likelihood of occurrence. We complement this most probable scenario with a discussion on controversial, extreme scenarios. Based on these findings we derive implications for industry, policy, and future research

Drei Aufsätze über Wettbewerbspolitik und Innovationsanreize

Diese Dissertation befasst sich mit dem Thema Innovationsökonomik. In einer allgemeinen Einführung werden wettbewerbspolitische Gesichtspunkte, die Innovationsanreize von Firmen beeinflussen, dargestellt. In drei einzelnen Arbeiten werden dann spezielle Fragestellungen intensiver analysiert. Die erste Arbeit behandelt die Wechselwirkungen von Firmenzusammenschlüssen und Innovationen, zwei zentrale Elemente der Wettbewerbsstrategie von Unternehmen. Der Schwerpunkt der Arbeit liegt dabei auf dem Einfluss von Firmenzusammenschlüssen auf die Innovationsaktivitäten und den Wettbewerb im Produktmarkt. Dabei werden auch mögliche Ineffizienzen, die sich durch Probleme bei der Integration der Firmen nach dem Zusammenschluss ergeben, untersucht. Es wird gezeigt, dass die optimale Investitionsaktivität sehr stark von der sich ergebenden Marktstruktur abhängt und es signifikante Unterschiede zwischen Insider und Outsider des Firmenzusammenschlusses gibt. In dem Modell mit linearer Nachfragefunktion und konstanten Grenzkosten steigern Zusammenschlüsse die soziale Wohlfahrt. Die zweite Arbeit betrachtet die unterschiedlichen Vorteile von kleinen und großen Firmen im Innovationswettbewerb. Während große Firmen typischerweise über einen besseren Zugang zu Produktmärkten verfügen, weisen kleine Firmen häufig eine bessere Forschungseffizienz auf. Diese verschiedenen Vorteile werfen unmittelbar die Frage nach Kooperationen auf. Im dargestellten Modell mit vier Unternehmen haben große Firmen die Möglichkeit kleine Firmen zu kaufen. Innovationen werden mittels Patentwettbewerb modelliert. Sequentielles Bieten ermöglicht es der ersten großen Firma strategisch zu handeln um eine Reaktion der zweiten großen Firma hervorzurufen. Ergeben sich hohe Effizienzen durch den Firmenzusammenschluss, so bevorzugen die großen Firmen eine unmittelbare Akquisition und es entsteht eine symmetrische Marktstruktur. Bei geringen Effizienzen wartet die erste Firma dagegen ab und zwingt die zweite Firma dadurch zum Kauf. Somit entsteht trotz symmetrischer Ausgangssituation eine asymmetrische Marktstruktur. Weiterhin wird gezeigt, dass Akquisitionen die Chancen für eine erfolgreiche Innovation erhöhen. Die dritte Arbeit befasst sich mit Forschungssubventionen. Dabei wird neben dem eigentlichen Ziel der Subvention -- der Förderung sozial erwünschter Projekte, die nicht genügend private Anreize zur Durchführung bieten -- die Signalwirkung einer Subvention betrachtet. Eine Staatsbehörde untersucht dabei die Projekte auf Risiken und Wohlfahrtswirkungen und entscheidet daraufhin über eine Förderung. Dies wird in einem einfachen Signalisierungsspiel mit zwei Risikoklassen von Forschungsprojekten modelliert. Die Staatsbehörde bevorzugt dabei riskante Projekte, die hohe erwartete soziale Gewinne versprechen, während Banken wenig riskante Projekte mit hohen privaten Gewinnen bevorzugen. Ermöglicht die Subvention lediglich die Unterscheidung von riskanten und weniger riskanten Projekten, so ist das Signal der Behörde wenig hilfreich für die Investitionsenscheidung der Banken. Bietet das Signal jedoch zusätzlich einen Hinweis auf die Qualität der Projekte, so können sich erhöhte, bzw. effizienter ausgewählte, private Investitionen ergeben. Im letzten Kapitel werden die wichtigsten Aussagen zusammengefasst sowie in abschließenden Bemerkungen der Zusammenhang der Ergebnisse erläutert.This thesis deals with the economics of innovation. In a general introduction we illustrate how several aspects of competition policy are linked to firms' innovation incentives. In three individual essays we analyze more specific issues. The first essay deals with interdependencies of mergers and innovation incentives. This is particularly relevant as both topics are central elements of a firm's competitive strategy. The essay focuses on the impact of mergers on innovative activity and competition in the product market. Possible inefficiencies due to organizational problems of mergers are accounted for. We show that optimal investment strategies depend on the resulting market structure and differ significantly from insider to outsider. In our linear model mergers turn out to increase social surplus. The second essay analyzes the different competitive advantages of large and small firms in innovation competition. While large firms typically have a better access to product markets, small firms often have a superior research efficiency. These distinct advantages immediately lead to the question of cooperations between firms. In our model we allow large firms to acquire small firms. In a pre-contest acquisition game large firms bid sequentially for small firms in order to combine respective advantages. Innovation competition is modeled as a patent contest. Sequential bidding allows the first large firms to bid strategically to induce a reaction of its competitor. For high efficiencies large firms prefer to acquire immediately, leading to a symmetric market structure. For low efficiencies strategic waiting of the first large firm leads to an asymmetric market structure even though the initial situation is symmetric. Furthermore, acquisitions increase the chances for successful innovation. The third essay deals with government subsidies to innovation. Government subsidies for research and development are intended to promote projects with high returns to society but too little private returns to be beneficial for private investors. Apart from the direct funding of these projects, government grants may serve as a signal of good investments for private investors. We use a simple signaling model to capture this phenomenon and allow for two types of risk classes. The agency has a preference for high risk projects as they promise high expected social returns, whereas banks prefer low risk projects with high private returns. In a setup where the subsidy can only be used to distinguish between high and low risk projects, government agency's signal is not very helpful for banks' investment decision. However, if the subsidy is accompanied by a quality signal, it may lead to increased or better selected private investments. The last chapter summarizes the main findings and presents some concluding remarks on the results of the essays

Three essays on competition policy and innovation incentives

This thesis deals with the economics of innovation. In a general introduction we illustrate how several aspects of competition policy are linked to firms’ innovation incentives. In three individual essays we analyze more specific issues. The first essay deals with interdependencies of mergers and innovation incentives. This is particularly relevant as both topics are central elements of a firm’s competitive strategy.

The second essay analyzes the different competitive advantages of large and small firms in innovation competition. While large firms typically have a better access to product markets, small firms often have a superior R&D efficiency. These distinct advantages immediately lead to the question of cooperations between firms. In our model we allow large firms to acquire small firms. In a pre-contest acquisition game large firms bid sequentially for small firms in order to combine respective advantages. Innovation competition is modeled as a patent contest. Sequential bidding allows the first large firms to bid strategically to induce a reaction of its competitor. For high efficiencies large firms prefer to acquire immediately, leading to a symmetric market structure. For low efficiencies strategic waiting of the first large firm leads to an asymmetric market structure even though the initial situation is symmetric. Furthermore, acquisitions increase the chances for successful innovation. The third essay deals with government subsidies to innovation. Government subsidies for R&D are intended to promote projects with high returns to society but too little private returns to be beneficial for private investors.

Acquisitions in a Patent Contest Model with Large and Small Firms

Big companies and small innovation factories possess different advantages in a patent contest. While large firms typically have a better access to product markets, small firms often have a superior R&D efficiency. In this paper I model a patent contest with asymmetric firms. In a pre-contest acquisition game large firms bid sequentially for small firms to combine respective advantages. Sequential bidding allows the first large firm to wait strategically and let the other firm acquire. For low efficiencies this leads to an asymmetric market structure even though the initial situation is symmetric. Furthermore, acquisitions increase the chances for a successful innovation.patent contest, sequential acquisitions

Government R&D subsidies as a signal for private investors

Government subsidies for R&D are intended to promote projects with high returns to society but too little private returns to be beneficial for private investors. This may be caused by spillovers or a low appropriability rate. Apart from the direct funding of these projects, government grants may serve as a signal for good investments for private investors. We use a simple signaling model with different types of R&D projects to capture this phenomenon. The agency has a preference for basic research projects as they promise high expected social returns, while banks prefer applied research projects with high private returns. In a setup where the subsidy can only be used to distinguish between basic and applied research projects, government agency's signal is not very helpful for banks. However, if the subsidy is accompanied by a quality signal, it can lead to increased or better selected private investments.Subsidies Innovation Asymmetric information Signaling
