Abstract
Starting from well-known empirical stylized facts of financial time series, we develop dynamic portfolio protection trading strategies based on econometric methods. As a criterion for riskiness, we consider the evolution of the value-at-risk spread from a GARCH model with normal innovations relative to a GARCH model with generalized innovations. These generalized innovations may for example follow a Student t, a generalized hyperbolic, an alpha-stable or a Generalized Pareto distribution (GPD). Our results indicate that the GPD distribution provides the strongest signals for avoiding tail risks. This is not surprising as the GPD distribution arises as a limit of tail behaviour in extreme value theory and therefore is especially suited to deal with tail risks. Out-of-sample backtests on 11 years of DAX futures data, indicate that the dynamic tail-risk protection strategy effectively reduces the tail risk while outperforming traditional portfolio protection strategies. The results are further validated by calculating the statistical significance of the results obtained using bootstrap methods. A number of robustness tests including application to other assets further underline the effectiveness of the strategy. Finally, by empirically testing for second-order stochastic dominance, we find that risk averse investors would be willing to pay a positive premium to move from a static buy-and-hold investment in the DAX future to the tail-risk protection strategy.

Joint R&D Subsidies, Related Variety, and Regional Innovation
T. Broekel, Matthias Brachert, M. Duschl, T. Brenner
International Regional Science Review,
Nr. 3,
2017
Abstract
Subsidies for research and development (R&D) are an important tool of public R&D policy, which motivates extensive scientific analyses and evaluations. This article adds to this literature by arguing that the effects of R&D subsidies go beyond the extension of organizations’ monetary resources invested into R&D. It is argued that collaboration induced by subsidized joint R&D projects yield significant effects that are missed in traditional analyses. An empirical study on the level of German labor market regions substantiates this claim, showing that collaborative R&D subsidies impact regions’ innovation growth when providing access to related variety and embedding regions into central positions in cross-regional knowledge networks.

Immigration and the Rise of American Ingenuity
Ufuk Akcigit, John Grigsby, Tom Nicholas
American Economic Review,
Nr. 5,
2017
Abstract
We build on the analysis in Akcigit, Grigsby, and Nicholas (2017) by using US patent and census data to examine the relationship between immigration and innovation. We construct a measure of foreign born expertise and show that technology areas where immigrant inventors were prevalent between 1880 and 1940 experienced more patenting and citations between 1940 and 2000. The contribution of immigrant inventors to US innovation was substantial. We also show that immigrant inventors were more productive than native born inventors; however, they received significantly lower levels of labor income. The immigrant inventor wage-gap cannot be explained by differentials in productivity.

Pionierkunde Staat: Wie die öffentliche Nachfrage private Innovationen antreiben kann

Enforceability of Noncompetition Agreements and Firm Innovation: Does State Regulation Matter?
Desheng Yin, Iftekhar Hasan, Nada Kobeissi, Haizhi Wang
Innovation: Organization & Management,
Nr. 2,
2017
Abstract
In this study, we examine how noncompetition agreements and the mobility of human capital – a core asset of any firm – affect innovations of publicly traded firms in the United States. We find that firms in states with stricter noncompetition enforcement have fewer patent applications. We also examine patent forward citations and find that tougher enforcement of such contracts is associated with less innovative patents. Notably, we find that stronger enforcement of noncompetition agreements impedes innovation for firms facing intense industry labor mobility. High-powered, equity-based compensation positively moderates the relationship between noncompetition enforcement and innovation, but only for the quality of innovation.

Effekte der Frühphasenunterstützung von Gründungen aus öffentlichen Forschungseinrichtungen – Das Beispiel Max-Planck-Innovation
D. Göktepe-Hultén, Viktor Slavtchev
Wirtschaft im Wandel,
Nr. 1,
2017
Abstract
Unternehmensgründungen durch Wissenschaftler werden als wichtiger Kanal zur Kommerzialisierung von Wissen und Technologien aus öffentlichen Forschungseinrichtungen und daher als Motor der wirtschaftlichen Entwicklung angesehen. Jedoch fehlen Wissenschaftlern oft wichtige unternehmerische Fähigkeiten und Kapital, sodass sie auf Unterstützung angewiesen sind. Am Beispiel der Max-Planck-Gesellschaft in Deutschland wird hier untersucht, inwiefern Unterstützung durch die öffentliche Forschungseinrichtung für angehende Gründer in der Frühphase den Gründungs- und Kommerzialisierungsprozess beschleunigen kann. Die Max-Planck-Gesellschaft ist eine der weltweit führenden Einrichtungen im Bereich der Grundlagenforschung und verfügt zudem mit Max-Planck-Innovation über eine Transfereinheit, die dezidiert und erfolgreich die Kommerzialisierung von Forschungsergebnissen aus der Gesellschaft vorantreibt. Die Ergebnisse der Untersuchung zeigen, dass die Unterstützung durch öffentliche Forschungseinrichtungen die frühe Erstellung eines tragfähigen Business-Plans und die frühe Akquise externen Kapitals fördert, sodass unterstützte Start-ups früher am Markt sind und Umsätze realisieren.

The Risk‐Taking Channel of Monetary Policy in the U.S.: Evidence from Corporate Loan Data
Manthos D. Delis, Iftekhar Hasan, Nikolaos Mylonidis
Journal of Money, Credit and Banking,
Nr. 1,
2017
Abstract
To study the presence of a risk-taking channel in the U.S., we build a comprehensive data set from the syndicated corporate loan market and measure monetary policy using different measures, most notably Taylor (1993) and Romer and Romer (2004) residuals. We identify a negative relation between monetary policy rates and bank risk-taking, especially in the run up to the 2007 financial crisis. However, this effect is purely supply-side driven only when using Taylor residuals and an ex ante measure of bank risk-taking. Our results highlight the sensitivity of the potency of the risk-taking channel to the measures of monetary policy innovations.

Investitionen in Köpfe stärker in den Fokus rücken – Stellungnahme zu den Neuregelungsplänen der GRW-Förderung in Sachsen-Anhalt
Die wirtschaftliche Lücke zu den westdeutschen Ländern kann in Sachsen-Anhalt nur verringert werden, wenn die Förderstrategie von Sachkapitalinvestitionen auf Investitionen in Köpfe umschwenkt. Für mehr Effizienz kommt es nun auf Innovationen an – und diese hängen vor allem von der Kreativität und der Qualifikation der Menschen im Land ab.

Creative Destruction and Subjective Well-being
Philippe Aghion, Ufuk Akcigit, Angus Deaton, Alexandra Roulet
American Economic Review,
Nr. 12,
2016
Abstract
In this paper we analyze the relationship between turnover-driven growth and subjective well-being. Our model of innovation-led growth and unemployment predicts that: (i) the effect of creative destruction on expected individual welfare should be unambiguously positive if we control for unemployment, less so if we do not; (ii) job creation has a positive and job destruction has a negative impact on well-being; (iii) job destruction has a less negative impact in areas with more generous unemployment insurance policies; and (iv) job creation has a more positive effect on individuals that are more forward-looking. The empirical analysis using cross sectional MSA (metropolitan statistical area)-level and individual-level data provide empirical support to these predictions.
