Concubinage or marriage? Informal and formal cooperations for innovation

Based on a sample of German innovating firms that contains information on formal and informal innovation cooperation between customers and suppliers, we state that firms perceive informal cooperation as being more important than formal cooperation modes. We then investigate the determinants of firms? decisions to engage into the respective cooperation modes. In line with previous empirical work, we do not find much empirical evidence for the relevance of incoming spillovers. In addition, our results suggest that this finding holds as well for informal cooper- ations. A firm?s ability to protect its proprietary innovations, however seems to be a key determinant of formal as well as informal cooperations. Furthermor absorptive capacity and the organizational structur of in-house R&D play an important role. Another relevant driver of vertical cooperations are the innovation dynamics at the industry level. Firms who operate an R&D department and firms who are involved in costly R&D projects tend to cooperate formally rather than informally.

The impact of regional age structure on entrepreneurship

Abstract Empirical studies based on individual data have found an inverse U-shaped relationship between age and the decision to start a business. Other studies have shown that becoming an entrepreneur is a regional event, with potential entrepreneurs benefiting from their local networks. This article links both strands of literature by introducing age-specific peer effects. Using changes in the age distribution of the population of western German regions over time, we found—in accordance with microlevel analyses—an inverse U-shaped relationship between the regional age structure and start-up activity in a region. Moreover, our findings suggest that the age-specific likelihood of becoming an entrepreneur changes with the size of the age cohort, pointing to the existence of age-specific peer effects.

R&D and productivity: Internal vs. external R&D - evidence from west german manufacturing industries

The paper explores the productivity effects of investment in external (contract) vs. internal (in-house) R&D in a sample of West-German Manufacturing Industries. The results provide strong evidence of a positive relationship between productivity and the share of external R&D in total R&D. This result is robust to alternative econometric specifications. Thus, findings suggest that the decision between internal and external R&D does matter. Moreover, results imply a nonlinear relationship between productivity and the share of external R&D for higher-technology industries, hinting at decreasing productivity effects of an increasing share of external in total R&D.

Religion and entrepreneurship

While considerable concern has emerged about the impact of religion on economic development, little is actually known about how religion impacts the decision making of individuals. This paper examines the influence of religion on the decision for people to become an entrepreneur. Based on a large-scale data set of nearly ninety thousand workers in India, this paper finds that religion shapes the entrepreneurial decision. In particular, some religions, such as Islam and Christianity, are found to be conducive to entrepreneurship, while others, such as Hinduism, inhibit entrepreneurship. In addition, the caste system is found to influence the propensity to become an entrepreneur. Individuals belonging to a backward caste exhibit a lower propensity to become an entrepreneur. Thus, the empirical evidence suggests that both religion and the tradition of the caste system influence entrepreneurship, suggesting a link between religion and economic behavior.

Biology and Selection Into Entrepreneurship—The Relevance of Prenatal Testosterone Exposure

This study examines the relationship between prenatal testosterone exposure (PTE) and selection into entrepreneurship. We argue that the relationship between PTE and entrepreneurial intent is positive and mediated by general and domain–specific risk–taking related to financial investment and professional career. Using the second–to–fourth digit ratio (2D:4D) as noninvasive retrospective marker for PTE, we identify two–step mediation effects of PTE on entrepreneurial intent through both general and domain–specific risk–taking. To account for possible socialization–based effects, we control for gender and parental self–employment. Applying ordinary least squares (OLS) regression analyses and structural equation models, we provide empirical evidence for a biological association between 2D:4D and entrepreneurial intent.

Does federally financed business R&D matter for US productivity growth?

This paper investigates the impact of federally financed business R&D on productivity of the US nonfarm business sector. Results of a cointegration analysis suggest that a long run relation between productivity and total (privately and federally financed) R&D capital stock exists. Moreover, the estimation results do not confirm the finding of previous empirical studies that the productivity effects of federally financed business R&D are lower compared with those of privately financed business R&D.

Financial Signaling by Innovative Nascent Entrepreneurs

Innovative new ventures fail if they cannot attract resources needed to commercialise new ideas and inventions. Obtaining external resources is a central issue for nascent entrepreneurs - people who are in the process of starting new ventures. We argue in this paper that, a way to deal with this problem is to signal appropriability and feasibility of innovation to the financiers through patenting and prototyping activities, right in the early stages of the venture. We build a new dataset of over 900 nascent entrepreneurs with information on financing from conventional sources as well as business angels and venture capitalists. Our results suggest that patenting and prototyping increase the likelihood of obtaining external finance, especially equity. However, the most important determinant of debt is house ownership. This indicates that new start-ups need to protect their innovations and at the same time, should also prototype the intended product in order to obtain start-up finance. New ventures should therefore strategically use their innovativeness in order to obtain external finance.

Knowledge Transfer in Buyer-Supplier Relationships – When It (Not) Occurs

Abuyer?s technical knowledge may increase the efficiency of its supplier. Suppliers, however, frequently maintain relationships with additional buyers. Knowledge disclosure then bears the risk of benefiting one?s own competitor due to opportunistic knowledge transmission through the common supplier. We show that in one-shot relationships no knowledge disclosure takes place because the supplier has an incentive for knowledge transmission and, in anticipation of this outcome, buyers refuse to disclose any of their knowledge. In repeated relationships knowledge disclosure is stabilized by larger technological proximity between buyers and suppliers and destabilized by the absolute value of the knowledge.

Gender differences in competitive preferences: new cross-country empirical evidence

This article provides new empirical evidence on gender differences in competitive preferences using a representative data set of more than 25 000 individuals from 36 countries. The empirical results show that the gender differences in competitive preferences are statistically significant in almost all countries, with women having, on average, a lower preference for competitive situations than men. Although relatively substantial in most countries, the magnitude of gender differences varies considerably between countries. Results of a regression analysis suggest that the gender differences persist even when controlling for a number of potentially relevant variables. Furthermore, gender differences among adult men and women are hardly affected by the stage of life cycle.

Qualitätssicherung in der volkswirtschaftlichen Auftragsforschung: Eine Fallstudie und ein Vorschlag

Abstract This paper presents a case study on commissioned economic research in Germany. We find deplorable methodological and empirical shortcomings in a prominent study by Munich’s ifo-Institute, on aspects of horizontal fiscal revenue sharing between German states. We suspect that this may not be an exceptional case but may point out problems of quality control in economic consultancy as a whole. Therefore, we suggest establishing a certified referee system in order to improve research quality.
