History, Microdata, and Endogenous Growth
Ufuk Akcigit, Tom Nicholas
Annual Review of Economics,
2019
Abstract
The study of economic growth is concerned with long-run changes, and therefore, historical data should be especially influential in informing the development of new theories. In this review, we draw on the recent literature to highlight areas in which study of history has played a particularly prominent role in improving our understanding of growth dynamics. Research at the intersection of historical data, theory, and empirics has the potential to reframe how we think about economic growth in much the same way that historical perspectives helped to shape the first generation of endogenous growth theories.

Weiter gute Stimmung in Sachsen-Anhalts Mittelstand
Der Mittelstand in Sachsen-Anhalt verzeichnet bislang keine stärkere Konjunkturabschwächung. Das geht aus einer gemeinsamen Umfrage von Creditreform und Leibniz-Institut für Wirtschaftsforschung Halle (IWH) hervor, an der sich 465 vorrangig kleine und mittlere Unternehmen aus Sachsen-Anhalt beteiligt haben. Die überwiegende Mehrzahl der befragten Unternehmen (72,4%) schätzt die aktuelle Geschäftslage weiterhin mit „sehr gut“ bzw. „gut“ ein. In der Vorjahresumfrage gab es ähnlich viele positive Meldungen (75,2% der Befragten). Günstig für die Wirtschaftslage im Mittelstand sind weiterhin die kräftige Binnennachfrage, der private Konsum und die Bautätigkeit.

Motivating High‐impact Innovation: Evidence from Managerial Compensation Contracts
Bill Francis, Iftekhar Hasan, Zenu Sharma, Maya Waisman
Financial Markets, Institutions and Instruments,
Nr. 3,
2019
Abstract
We investigate the relationship between Chief Executive Officer (CEO) compensation and firm innovation and find that long‐term incentives in the form of options, especially unvested options, and protection from managerial termination in the form of golden parachutes are positively related to corporate innovation, and particularly to high‐impact, exploratory (new knowledge creation) invention. Conversely, non‐equity pay has a detrimental effect on the input, output and impact of innovation. Tests using the passage of an option expensing regulation (FAS 123R) as an exogenous shock to option compensation suggest a causal interpretation for the link between long‐term pay incentives, patents and citations. Furthermore, we find that the decline in option pay following the implementation of FAS 123R has led to a significant reduction in exploratory innovation and therefore had a detrimental effect on innovation output. Overall, our findings support the idea that compensation contracts that protect from early project failure and incentivize long‐term commitment are more suitable for inducing high‐impact corporate innovation.

Do Diasporas Affect Regional Knowledge Transfer within Host Countries? A Panel Analysis of German R&D Collaborations
Lutz Schneider, Alexander Kubis, Mirko Titze
Regional Studies,
Nr. 1,
2019
Abstract
Interactive regional learning involving various actors is considered a precondition for successful innovations and, hence, for regional development. Diasporas as non-native ethnic groups are regarded as beneficial since they enrich the creative class by broadening the cultural base and introducing new routines. Using data on research and development (R&D) collaboration projects, the analysis provides tentative evidence that the size of diasporas positively affects the region’s share of outward R&D linkages enabling the exchange of knowledge. The empirical analysis further confirms that these interactions mainly occur between regions hosting the same diasporas, pointing to a positive effect of ethnic proximity rather than ethnic diversity.

Identifying Cooperation for Innovation – A Comparison of Data Sources
Michael Fritsch, Matthias Piontek, Mirko Titze
Abstract
The value of social network analysis is critically dependent on the comprehensive and reliable identification of actors and their relationships. We compare regional knowledge networks based on different types of data sources, namely, co-patents, co-publications, and publicly subsidised collaborative Research and Development projects. Moreover, by combining these three data sources, we construct a multilayer network that provides a comprehensive picture of intraregional interactions. By comparing the networks based on the data sources, we address the problems of coverage and selection bias. We observe that using only one data source leads to a severe underestimation of regional knowledge interactions, especially those of private sector firms and independent researchers. The key role of universities that connect many regional actors is identified in all three types of data.

Innovation and Top Income Inequality
Philippe Aghion, Ufuk Akcigit, Antonin Bergeaud, Richard Blundell, David Hemous
Review of Economic Studies,
Nr. 1,
2019
Abstract
In this article, we use cross-state panel and cross-U.S. commuting-zone data to look at the relationship between innovation, top income inequality and social mobility. We find positive correlations between measures of innovation and top income inequality. We also show that the correlations between innovation and broad measures of inequality are not significant. Next, using instrumental variable analysis, we argue that these correlations at least partly reflect a causality from innovation to top income shares. Finally, we show that innovation, particularly by new entrants, is positively associated with social mobility, but less so in local areas with more intense lobbying activities.

Innovation Cooperation in East and West Germany: A Study on the Regional and Technological Impact
Uwe Cantner, Alexander Giebler, Jutta Günther, Maria Kristalova, Andreas Meder
International Journal of Computational Economics and Econometrics,
3/4
2018
Abstract
In this paper, we investigate the impact of regional and technological innovation systems on innovation cooperation. We develop an indicator applicable to regions, which demonstrates the relative regional impact on innovation cooperation. Applying this method to German patent data, we find that regional differences in the degree of innovation cooperation do not only depend on the technology structure of a region but also on specific regional effects. High-tech oriented regions, whether east or west, are not automatically highly cooperative regions. East German regions have experienced a dynamic development of innovation cooperation since re-unification in 1990. Their cooperation intensity remains higher than in West German regions.

Measuring the Impact of Household Innovation using Administrative Data
Javier Miranda, Nikolas Zolas
NBER Working Paper,
Nr. 25259,
2018
Abstract
We link USPTO patent data to U.S. Census Bureau administrative records on individuals and firms. The combined dataset provides us with a directory of patenting household inventors as well as a time-series directory of self-employed businesses tied to household innovations. We describe the characteristics of household inventors by race, age, gender and U.S. origin, as well as the types of patented innovations pursued by these inventors. Business data allows us to highlight how patents shape the early life-cycle dynamics of nonemployer businesses. We find household innovators are disproportionately U.S. born, white and their age distribution has thicker tails relative to business innovators. Data shows there is a deficit of female and black inventors. Household inventors tend to work in consumer product areas compared to traditional business patents. While patented household innovations do not have the same impact of business innovations their uniqueness and impact remains surprisingly high. Back of the envelope calculations suggest patented household innovations granted between 2000 and 2011 might generate $5.0B in revenue (2000 dollars).
