Abstract
This paper investigates the impact of sustained lower productivity growth on exports, by looking at the role of the productivity distribution and allocative efficiency as drivers of export performance. It follows and goes beyond the work of Barba Navaretti et al. (2017), analysing the effects of productivity on exports depending on the dynamics of allocative efficiency. Low productivity growth is a well-documented stylised fact in Western countries – and possibly a reality likely to persist for some time. What could be the impact of persistent sluggish growth of productivity on exports? To shed light on this question, this paper examines the relationship between the productivity distribution of firms and sectoral export performance. The structure of firms within countries or even sectors matters tremendously for the nexus between productivity and exports at the macroeconomic level, as the theoretical and empirical literature documents. For instance, whether too few firms at the top (lack of innovation) or too many firms at the bottom (weak market selection) drives slow average productivity at the macro level has very different implications and therefore demands different policy responses.

Crowdsourced Innovation: How Community Managers Affect Crowd Activities
Sabrina Jeworrek, Lars Hornuf
IWH Discussion Papers,
No. 13,
2018
Abstract
In this study, we investigate whether and to what extent community managers in online collaborative communities can stimulate crowd activities through their engagement. Using a novel data set of 22 large online idea crowdsourcing campaigns, we find that active engagement of community managers positively affects crowd activities in an inverted U-shaped manner. Moreover, we evidence that intellectual stimulation by managers increases community participation, while individual consideration of users has no impact on user activities. Finally, the data reveal that community manager activities that require more effort, such as media file uploads instead of simple written comments, have a larger effect on crowd participation.

Growth through Heterogeneous Innovations
Ufuk Akcigit, William R. Kerr
Journal of Political Economy,
No. 4,
2018
Abstract
We build a tractable growth model in which multiproduct incumbents invest in internal innovations to improve their existing products, while new entrants and incumbents invest in external innovations to acquire new product lines. External and internal innovations generate heterogeneous innovation qualities, and firm size affects innovation incentives. We analyze how different types of innovation contribute to economic growth and the role of the firm size distribution. Our model aligns with many observed empirical regularities, and we quantify our framework with Census Bureau and patent data for US firms. Internal innovation scales moderately faster with firm size than external innovation.

On the Returns to Invention within Firms: Evidence from Finland
Philippe Aghion, Ufuk Akcigit, Ari Hyytinen, Otto Toivanen
American Economic Association Papers and Proceedings,
2018
Abstract
In this paper we merge individual income data, firm-level data, patenting data, and IQ data in Finland over the period 1988–2012 to analyze the returns to invention for inventors and their coworkers or stakeholders within the same firm. We find that: (i) inventors collect only 8 percent of the total private return from invention; (ii) entrepreneurs get over 44 percent of the total gains; (iii) bluecollar workers get about 26 percent of the gains and the rest goes to white-collar workers. Moreover, entrepreneurs start with significant negative returns prior to the patent application, but their returns subsequently become highly positive.

The Economic Development of Saxony-Anhalt since 1990
Oliver Holtemöller, Axel Lindner
IWH Discussion Papers,
No. 6,
2018
Abstract
This article describes the economic development of Saxony-Anhalt since 1990 in the context of the East German transition from a centrally planned economy to a market economy. In the early 1990s the economy of Saxony-Anhalt caught up quickly with West Germany, mainly because the capital stock was modernized and expanded. Convergence, however, has almost come to a halt for some time now and gross domestic product per employed person is still about 20% below the West German level. The challenge for economic policy is to further the catching-up process by fostering research and innovation and improving the skills of the workforce.

Joint Economic Forecast Spring 2018: Germany’s Economic Experts Raise Forecast Slightly
Berlin, 19 April – Germany’s leading economic experts raised their forecasts for 2018 and 2019 slightly in their Spring Joint Economic Forecast released on Thursday in Berlin. They now expect economic growth of 2.2 percent for this year and 2.0 percent for 2019, versus 2.0 percent and 1.8 percent respectively in their autumn forecast. “The German economy is still booming, but the air is getting thinner as unused capacities are shrinking“, notes Timo Wollmershaeuser, ifo Head of Economic Forecasting. Commenting on the new German government’s economic policy, he adds: “It is precisely when the government’s coffers are full that fiscal policy should reflect the implications of its actions for overall economic stability and the sustainability of public finances. The extension of statutory pension benefits outlined in the coalition agreement runs counter to the idea of sustainability.”

Ostdeutsche Flächenländer können mit westdeutschem Wirtschaftswachstum nicht mithalten
Deutschlands Wirtschaft ist im Jahr 2017 um stolze 2,2% gewachsen. Bei näherem Hinsehen offenbart sich aber schnell: Die Wachstumszahlen von Bundesländern wie Bayern (+2,8%), Bremen (+3,3%) und Niedersachsen (+2,5%) verheißen deutlich mehr als die der ostdeutschen Flächenländer, beispielsweise die Sachsens (+1,4%) und vor allem Sachsen-Anhalts (0,8%), wie die heute vorgelegten BIP-Wachstumszahlen des Arbeitskreises Volkswirtschaftliche Gesamtrechnungen der Länder (VGRdL) für 2017 zeigen. Damit geht die Schere zwischen Ost- und Westdeutschland nicht weiter zu. „Der Aufholprozess stagniert; die ostdeutschen Länder sollten ihre Wirtschaftspolitik mehr auf die bessere Qualifizierung der Erwerbstätigen und Innovationen ausrichten“, so Oliver Holtemöller, Vizepräsident des Leibniz-Instituts für Wirtschaftsforschung Halle (IWH) und Leiter der Abteilung Makroökonomik.

Differences Make a Difference: Diversity in Social Learning and Value Creation
Yiwei Fang, Bill Francis, Iftekhar Hasan
Journal of Corporate Finance,
2018
Abstract
Prior research has demonstrated that CEOs learn privileged information from their social connections. Going beyond the importance of the number of social ties in a CEO's social network, this paper studies the value generated from a diverse social environment. We construct an index of social-network heterogeneity (SNH) that captures the extent to which CEOs are connected to people of different demographic attributes and skill sets. We find that higher CEO SNH leads to greater firm value through the channels of better corporate innovation and diversified M&As. Overall, the evidence suggests that CEOs' exposure to human diversity enhances social learning and creates greater growth opportunities for firms.

Polen am Scheideweg
Polen hat bislang einen recht erfolgreichen wirtschaftlichen Aufholprozess durchlaufen, der nun ins Stocken gerät. Der so genannte „Morawiecki-Plan“, den Oliver Holtemöller und Martina Kämpfe vom Leibniz-Institut für Wirtschafts-forschung Halle (IWH) nun genauer unter die Lupe nahmen, soll dem Aufholprozess wieder mehr Schwung verleihen. Ihr Fazit: Um nicht in der „Middle-Income-Trap“ zu landen, muss Polen innovative und junge Unternehmen stärker fördern und den Bildungssektor weiter ausbauen.
