Abstract
Die Ereignisse der letzten Jahre haben die Debatte über eine Deindustrialisierung Deutschlands auf die Tagesordnung gesetzt. Die Corona-Pandemie, Unsicherheiten im Umgang mit China und der Krieg in der Ukraine belasten die deutsche Wirtschaft stark. Unterbrochene Lieferketten, fehlende Rohstoffe und vor allem die in ungeahnte Höhen gestiegenen Energiepreise verunsichern die Unternehmen. Aufgrund deutlich günstigerer Energiekosten und der Subventionspolitik in den USA gibt es Befürchtungen, dass insbesondere energieintensive Unternehmen abwandern und der Industriestandort Deutschland an Wettbewerbsfähigkeit verliert. Ist diese Sorge berechtigt, und wie kann die Politik gegensteuern?

Do Larger Firms Exert More Market Power? Markups and Markdowns along the Size Distribution
Matthias Mertens, Bernardo Mottironi
IWH-CompNet Discussion Papers,
Nr. 1,
2023
Abstract
Several models posit a positive cross-sectional correlation between markups and firm size, which characterizes misallocation, factor shares, and gains from trade. Accounting for labor market power in markup estimation, we find instead that larger firms have lower product markups but higher wage markdowns. The negative markup-size correlation turns positive when conditioning on markdowns, suggesting interactions between product and labor market power. Our findings are robust to common criticism (e.g., price bias, non-neutral technology) and hold across 19 European countries. We discuss possible mechanisms and resulting implications, highlighting the importance of studying input and output market power in a unified framework.

The East-West German Gap in Revenue Productivity: Just a Tale of Output Prices?
Matthias Mertens, Steffen Müller
Journal of Comparative Economics,
Nr. 3,
2022
Abstract
East German manufacturers’ revenue productivity is substantially below West German levels, even three decades after German unification. Using firm-product-level data with product quantities and prices, we analyze the role of product specialization and show that the prominent “extended work bench hypothesis” cannot explain these sustained productivity differences. Eastern firms specialize in simpler product varieties generating less consumer value and being manufactured with less or cheaper inputs. Yet, such specialization cannot explain the productivity gap because Eastern firms are physically less productive for given product prices. Hence, there is a genuine price-adjusted physical productivity disadvantage of Eastern compared to Western firms.

Die Ost-West-Produktivitätslücke: Die Rolle von Produktspezialisierung, Produktpreisunterschieden und physischer Produktivität
Matthias Mertens, Steffen Müller
Wirtschaft im Wandel,
Nr. 1,
2022
Abstract
Auch 30 Jahre nach der Deutschen Vereinigung erreicht die ostdeutsche Wirtschaft nur 82% der westdeutschen Arbeitsproduktivität. Dieser Unterschied in der gesamtwirtschaftlichen Arbeitsproduktivität steht in engem Zusammenhang mit vielen wirtschaftlichen und gesellschaftlichen Problemen, denen Ostdeutschland heute gegenübersteht. Auf Basis differenzierter Daten zu den einzelnen Produkten, die Firmen im deutschen Verarbeitenden Gewerbe herstellen, untersuchen wir in diesem Beitrag, wie sich ost- und westdeutsche Firmen bezüglich Produktspezialisierung, Produktpreisen und technischer Effizienz unterscheiden. Wir zeigen auf, dass der Osten – entgegen der Hypothese der „verlängerten Werkbank“ – nicht aufgrund einer Spezialisierung auf Vorprodukte weniger produktiv als der Westen ist. Obwohl Ostprodukte zu deutlich geringeren Preisen verkauft werden, können auch Preisunterschiede zwischen Ost- und Westfirmen den Produktivitätsrückstand nicht erklären. Stattdessen sind Faktoren, welche die physische Produktivität (technische Effizienz) von Unternehmen beeinflussen, entscheidend, um den Produktivitätsrückstand auf Unternehmensebene zu erklären.

Bank Failures, Local Business Dynamics, and Government Policy

Small Business Economics,
Nr. 4,
2022
Abstract
Using MSA-level data over 1994–2014, we study the effect of bank failures on local business dynamics, in the form of net business formation and net job creation. We find that at least one bank failure in the metropolitan statistical area (MSA) with the mean population prevents approximately 475 net businesses from forming in that area, compared with MSAs that experience no bank failures, ceteris paribus. The equivalent effect on net job creation is 16,433 net job losses. Our results are even stronger for small businesses, which are usually more dependent on bank-firm relationships. These effects point to significant welfare losses stemming from bank failures, highlighting an important role for government intervention. We show that the Troubled Asset Relief Program (TARP) is effective in reducing the negative effects of bank failures on local business dynamics. This positive effect of TARP is quite uniform across small and large firms.

European Firm Concentration and Aggregate Productivity
Tommaso Bighelli, Filippo di Mauro, Marc Melitz, Matthias Mertens
Abstract
This article derives a European Herfindahl-Hirschman concentration index from 15 micro-aggregated country datasets. In the last decade, European concentration rose due to a reallocation of economic activity towards large and concentrated industries. Over the same period, productivity gains from reallocation accounted for 50% of European productivity growth and markups stayed constant. Using country-industry variation, we show that changes in concentration are positively associated with changes in productivity and allocative efficiency. This holds across most sectors and countries and supports the notion that rising concentration in Europe reflects a more efficient market environment rather than weak competition and rising market power.

Der Ost-West-Produktivitätsunterschied: Was sagt die mikroökonomische Forschung?

Wirtschaftsdienst,
Konferenzband "30 Jahre Deutsche Einheit", März
2021
Abstract
Laut Volkswirtschaftlicher Gesamtrechnung erreicht die ostdeutsche Wirtschaft auch 30 Jahre nach dem Fall des Eisernen Vorhangs nur 80 % der westdeutschen Arbeitsproduktivität. Dieser Unterschied in der gesamtwirtschaftlichen Arbeitsproduktivität geht Hand in Hand mit vielen der wirtschaftlichen und gesellschaftlichen Probleme, denen Ostdeutschland heute gegenübersteht. Um die Ursachen des aggregierten Produktivitätsgefälles zu verstehen, wird die neuere Literatur zum Ost-West-Gefälle diskutiert, die granulare Daten auf Firmen- und Produktebene verwendet. Die Evidenz zeigt die Relevanz von Produktivitätsunterschieden auf Firmenebene für die aggregierte Lücke deutlich und stellt gängige Hypothesen infrage, die aus aggregierten Daten abgeleitet werden.

Promoting Higher Productivity in China — Does Innovation Expenditure Really Matter?
Hoang Minh Duy, Filippo di Mauro, Jo Van Biesebroeck
Singapore Economic Review,
Nr. 5,
2020
Abstract
The slowing down of the global economy adds additional challenges to China? economic policies as the country orchestrates its transition to lower resource dependency and higher technology intensity of output. Are policies aimed at technologically advanced sectors the right answer? Drawing from a newly created dataset of firms? balance sheets over the period 1998?2013, matched with patents data until 2009, we uncover that expenditure in innovation had limited effect on boosting productivity, without generating a clear gain in overall productivity for the high-tech sector. As a matter of fact, there is a much higher dispersion in productivity outcomes in firms belonging to the low-technology sectors, which derives from a bunch of champions in those sectors scoring higher productivity dynamics than in the High-technology sectors. The paper finds those barriers to entry and in general, market power of incumbents in the high-tech generate less than optimal resource reallocation, which hampers the overall productivity. Policies should presumably aim at removing such obstacles rather than solely promote innovation expenditure.
