Make-or-Buy Decisions in Patent Related Services

Among the most prominent theoretical frameworks dealing with the economic underlyings of firms’ make-or-buy decisions are Transaction Cost Economics (TCE) and the Resourced Based View (RBV). Relying on panel data covering 107 European firms over eight years I test predictions from both TCE and RBV with regard to the outsourcing of patent related services simultaneously. Modelling the share of outsourced patent applications in a Negative Binomial Panel Regression Model I find joint explanatory po...

Institutionalized Incentives for Ingenuity – Patent Value and the German Employees’ Inventions Act

Germany is one of few countries in which the monetary compensation for inventors is not only determined by negotiations between employer and employee-inventor, but also by relatively precise legal provisions. In this paper, we describe the characteristics of the German Employees’ Inventions Act (GEIA) and discuss which incentives it creates. We rely on responses from a recent survey of 3,350 German inventors to test hypotheses regarding this institution. We conclude from our data that the law cr...

Everything you Always Wanted to Know About Inventors (But Never Asked): Evidence from the PatVal-EU Survey

Based on a survey of the inventors of 9,017 European patented inventions, this paper provides new information about the characteristics of European inventors, the sources of their knowledge, the importance of formal and informal collaborations, the motivations to invent, and the actual use and economic value of the patents.

Tracing Mobile Inventors – The Causality between Inventor Mobility and Inventor Productivity

This paper analyzes the causality between inventor productivity and inventor mobility. The results show that the level of education has no influence on inventor productivity. Making use of external sources of knowledge, on the contrary, has a significant effect on productivity. Finally, firm size has a positive impact on productivity. Firm size also influences inventor mobility, although negatively. Whereas existing research implicitly assumes causality to point in one direction, this study ex-a...

Modeling the Duration of Patent Examination at the European Patent Office

We analyze the duration of the patent examination process at the European Patent Office (EPO). Our data contain information related to the patent’s economic and technical relevance, EPO capacity and workload as well as novel citation measures which are derived from the EPO’s search reports. In our multivariate analysis we estimate competing risk specifications in order to characterize differences in the processes leading to a withdrawal of the application by the applicant, a refusal of the paten...

Sample- and segment-size specific Model Selection in Mixture Regression Analysis

As mixture regression models increasingly receive attention from both theory and practice, the question of selecting the correct number of segments gains urgency. A misspecification can lead to an under- or oversegmentation, thus resulting in flawed management decisions on customer targeting or product positioning. This paper presents the results of an extensive simulation study that examines the performance of commonly used information criteria in a mixture regression context with normal data. ...

Einfluss sozialer Präferenzen auf die Steuerung dezentraler Einheiten

Economic theory typically assumes that people are only interested in their own material wealth. Experimentalists have recently discovered that this assumption is not true under all circumstances. Especially in regular face to face interactions, not only the personal well-being but also the well-being of other people is important for individual decisions. These findings are particularly important for the design of incentive systems to control the behaviour of managers of decentralized organizatio...

When prices hardly matter: Incomplete insurance contracts and markets for repair goods

This paper looks at markets characterized by the fact that the demand side is insured. In these markets a consumer purchases a good to compensate consequen¬ces of unfavorable events, such as an accident or an illness. Insurance policies in most lines of insurance base indemnity on the insured’s actual expenses, i.e., the insured would be partially or completely reimbursed when purchasing certain goods. In this setting we discuss the interaction between insurance and repair markets by focusing, o...

Erweiterungen zu „Simplified Discounting Rules in Binomial Models“ von Frank Richter

Bei der Bewertung von Unternehmen ist es üblich, die erwarteten Überschussverteilungen mit Kapitalkosten zu diskontieren, welche aus dem Capital Asset Pricing Model (CAPM) abgeleitet werden. In diesem Zusammenhang hat Richter unter der Prämisse eines Binomialmodells für die Entwicklung der Cashflows und der Marktrendite unlängst Bedingungen formuliert, die eine Anwendung von konstanten Kapitalkosten erlauben. Die vorliegende Arbeit erweitert die Überlegungen von Richter dahingehend, dass neben d...

Unternehmensbewertung mit dem Nachsteuer-CAPM?

In jüngerer Zeit verwenden Teile der Literatur das auf Brennan zurückgehende Nachsteuer- CAPM, um Unternehmenswerte nach (differenzierten) persönlichen Steuern zu bestimmen. In diesem Beitrag wird das Modell auf drei unterschiedliche Steuersätze erweitert. Gezeigt wird, dass das Nachsteuer-CAPM nicht zur Diskontierung von Nettocashflows verwendet werden darf, da es Bruttorenditen erzeugt. Daneben sprechen ein prohibitiver Datenbeschaffungsaufwand sowie methodische Probleme bei der Formulierung v...
