The East-West German Gap in Revenue Productivity: Just a Tale of Output Prices?
Matthias Mertens, Steffen Müller
Abstract
East German manufacturers’ revenue productivity (value-added per worker) is some 8 (25) percent below West German levels, even three decades after German unification. Using firm-product-level data containing information on product quantities and prices, we analyse the role of product specialisation and reject the prominent ‚extended work bench hypothesis‘, stating a specialisation of Eastern firms in the intermediate input production as explanation for these sustained productivity differences. We decompose the East’s revenue productivity disadvantage into Eastern firms selling at lower prices and producing more physical output for given amounts of inputs within ten-digit product industries. This suggests that Eastern firms specialise vertically in simpler product varieties generating less consumer value but being manufactured with less or cheaper inputs. Vertical specialisation, however, does not explain the productivity gap as Eastern firms are physically less productive for given product prices, implying a genuine physical productivity disadvantage of Eastern compared to Western firms

Ostdeutschland 30 Jahre nach dem Mauerfall: Erreichtes und wirtschaftspolitischer Handlungsbedarf
Reint E. Gropp, Gerhard Heimpold
Wirtschaftsdienst,
Nr. 7,
2019
Abstract
Dass Ostdeutschland bei der Verringerung der Ost-West-Produktivitätslücke nur noch wenig vorankommt, hat nicht nur mit fehlenden Konzernzentralen zu tun. Eine Produktivitätslücke existiert in Betrieben aller Größen. Sie ist im städtischen Raum größer als im ländlichen. Der Fachkräftemangel ist der neue Entwicklungsengpass. Um gegenzusteuern, sollte die Wirtschaftspolitik nicht durch zusätzliche Subventionen, die an die Arbeitsplatzschaffung und -erhaltung gebunden sind, den Produktivitätsdruck abschwächen. Die Produktivitätspotenziale der ostdeutschen Städte gilt es zu heben. Fachkräftesicherung verlangt qualifizierte Zuwanderung mit einer entsprechenden Willkommenskultur in Ostdeutschland.

Innovation, Reallocation, and Growth
Daron Acemoglu, Ufuk Akcigit, Harun Alp, Nicholas Bloom, William R. Kerr
American Economic Review,
Nr. 11,
2018
Abstract
We build a model of firm-level innovation, productivity growth, and reallocation featuring endogenous entry and exit. A new and central economic force is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model using US Census microdata on firm-level output, R&D, and patenting. The model provides a good fit to the dynamics of firm entry and exit, output, and R&D. Taxing the continued operation of incumbents can lead to sizable gains (of the order of 1.4 percent improvement in welfare) by encouraging exit of less productive firms and freeing up skilled labor to be used for R&D by high-type incumbents. Subsidies to the R&D of incumbents do not achieve this objective because they encourage the survival and expansion of low-type firms.

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.

Assessing European Competitiveness: The New CompNet Microbased Database
Paloma Lopez-Garcia, Filippo di Mauro
ECB Working Paper,
Nr. 1764,
2015
Abstract
Drawing from confidential firm-level balance sheets for 17 European countries (13 Euro-Area), the paper documents the newly expanded database of cross-country comparable competitiveness-related indicators built by the Competitiveness Research Network (CompNet). The new database provides information on the distribution of labour productivity, TFP, ULC or size of firms in detailed 2-digit industries but also within broad macrosectors or considering the full economy. Most importantly, the expanded database includes detailed information on critical determinants of competitiveness such as the financial position of the firm, its exporting intensity, employment creation or price-cost margins. Both the distribution of all those variables, within each industry, but also their joint analysis with the productivity of the firm provides critical insights to both policy-makers and researchers regarding aggregate trends dynamics. The current database comprises 17 EU countries, with information for 56 industries, including both manufacturing and services, over the period 1995-2012. The paper aims at analysing the structure and characteristics of this novel database, pointing out a number of results that are relevant to study productivity developments and its drivers. For instance, by using covariances between productivity and employment the paper shows that the drop in employment which occurred during the recent crisis appears to have had “cleansing effects” on EU economies, as it seems to have accelerated resource reallocation towards the most productive firms, particularly in economies under stress. Lastly, this paper will be complemented by four forthcoming papers, each providing an in-depth description and methodological overview of each of the main groups of CompNet indicators (financial, trade-related, product and labour market).

Wirtschaft im Wandel,
Nr. 3,
2014
Abstract
Internationale Medien haben ein anhaltend großes Interesse an den wirtschaftlichen Entwicklungen nach der Herstellung der Einheit Deutschlands. Dies gilt in spezieller Weise für Südkorea, das die Erfahrung eines geteilten Landes mit Deutschland gemeinsam hat. Dort wird der 25. Jahrestag des Mauerfalls zum Anlass genommen, über die deutsche Entwicklung zu berichten und wenn möglich für die Zukunft des eigenen Landes Lehren zu ziehen. Am 20. März 2014 wurde Dr. Gerhard Heimpold, kommissarischer Leiter der Abteilung Strukturökonomik des IWH, von einem Team des Fernsehsenders „Korean Broadcasting Systems“ (KBS), einem öffentlich-rechtlichen Fernsehsender in der Republik Korea, zur Deutschen Einheit sowie zum wirtschaftlichen Aufholprozess der Neuen Länder und speziell Sachsen-Anhalts interviewt. Eine Schriftfassung dieses Gesprächs wird nachfolgend wiedergegeben.

Micro-Based Evidence of EU Competitiveness: The CompNet Database
Filippo di Mauro, et al.
ECB Working Paper,
Nr. 1634,
2014
Abstract
Drawing from confidential firm-level balance sheets in 11 European countries, the paper presents a novel sectoral database of comparable productivity indicators built by members of the Competitiveness Research Network (CompNet) using a newly developed research infrastructure. Beyond aggregate information available from industry statistics of Eurostat or EU KLEMS, the paper provides information on the distribution of firms across several dimensions related to competitiveness, e.g. productivity and size. The database comprises so far 11 countries, with information for 58 sectors over the period 1995-2011. The paper documents the development of the new research infrastructure, describes the database, and shows some preliminary results. Among them, it shows that there is large heterogeneity in terms of firm productivity or size within narrowly defined industries in all countries. Productivity, and above all, size distribution are very skewed across countries, with a thick left-tail of low productive firms. Moreover, firms at both ends of the distribution show very different dynamics in terms of productivity and unit labour costs. Within-sector heterogeneity and productivity dispersion are positively correlated to aggregate productivity given the possibility of reallocating resources from less to more productive firms. To this extent, we show how allocative efficiency varies across countries, and more interestingly, over different periods of time. Finally, we apply the new database to illustrate the importance of productivity dispersion to explain aggregate trade results.

Im Fokus: Veränderungen im Städtesystem Russlands: Fortdauernde Tendenz zur Konzentration
Albrecht Kauffmann
Wirtschaft im Wandel,
Nr. 1,
2014
Abstract
Nach dem Ende der kommunistischen Herrschaft in Russland haben der darauf folgende Transformationsschock und die durch ihn in Gang gesetzten Marktprozesse Veränderungen im Städtesystem bewirkt. Anhand eigens aufbereiteter Daten der amtlichen russischen Städtestatistik geht der Beitrag diesen Veränderungen nach. Wichtigste Erkenntnisse sind die Erhöhung der Konzentration der urbanen Bevölkerung und die Verstärkung der Gegensätze zwischen urbanen Kernen und peripheren Räumen. Für die Zeit etwa ab dem Jahr 2000 darf vermutet werden, dass marktwirtschaftliche Prozesse die Veränderungen im Städtesystem beeinflussen. Hierzu kann die Neue Ökonomische Geographie einen wesentlichen Erklärungsbeitrag leisten, insbesondere vor dem Hintergrund des im Zuge der Preisliberalisierung erfolgten, noch nachwirkenden realen Anstiegs der Kosten des Frachtverkehrs. Diese schützen zum einen die im Zentrum ansässigen Unternehmen vor Wettbewerbern außerhalb der Zentren und verteuern zum anderen die Versorgung der peripheren Regionen. Die Untersuchungsergebnisse stützen die Hypothese, dass steigende Transportkosten die Raumstruktur beeinflussen. Vor dem Hintergrund eines möglichen Energiepreisanstiegs besitzen die Beobachtungen am Städtesystem Russlands daher auch für Deutschland Relevanz.

Cooperation Events, Ego-Network Characteristics and Firm Innovativeness – Empirical Evidence from the German Laser Industry
Muhamed Kudic, Katja Guhr
IWH Discussion Papers,
Nr. 6,
2013
Abstract
We study how firm innovativeness is related to individual cooperation events and the structure and dynamics of firms’ ego-networks employing a unique panel dataset for the full population of 233 German laser source manufactures between 1990 and 2010. Firm innovativeness is measured by yearly patent applications as well as patent grants with a two year time-lag. Network measures are calculated on the basis of 570 knowledge-related publicly funded R&D alliances. Estimation results from a panel data count model with fixed effects are suggestive of direct innovation effects due to individual cooperation events, but only as long as structural ego-network characteristics are neglected. Innovativeness is robustly related to ego-network size and ego-network brokerage whereas ego-network density reveals some surprising results.
