European Firm Concentration and Aggregate Productivity

Abstract
This paper 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 toward large and concentrated industries. Over the same period, productivity gains from an increasing allocative efficiency of the European market accounted for 50% of European productivity growth while 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.

Gefahr einer Gaslücke gegenüber April deutlich verringert – aber Versorgungsrisiken bleiben
Die Wahrscheinlichkeit einer Versorgungslücke mit Erdgas im Fall eines Stopps russischer Lieferungen ist gegenüber April deutlich gesunken. Zu diesem Ergebnis kommt eine aktualisierte Simulationsrechnung der an der Gemeinschaftsdiagnose beteiligten Institute. Trotz mittlerweile deutlich besser gefüllter Speicher sind damit aber noch nicht alle Risiken für die Gasversorgung der Industrie im Winterhalbjahr 2022/2023 gebannt. Es ist daher ratsam, zeitnah die Preissignale bei den Verbrauchern ankommen zu lassen.

Fallende Lohnquoten: Die Rolle von Technologie und Marktmacht
Matthias Mertens
Wirtschaft im Wandel,
Nr. 2,
2022
Abstract
Die Lohnquote, definiert als die Summe der Arbeitnehmerentgelte geteilt durch die Gesamtproduktion einer Volkswirtschaft, ist in den letzten 40 Jahren in vielen Ländern gefallen. Das Fallen der Lohnquote besitzt potenziell weitreichende Implikationen für das Ausmaß an Ungleichheit und für den Wohlstand von Arbeitnehmerinnen und Arbeitnehmern. Daneben kann eine fallende Lohnquote auch ein Anzeichen für einen Anstieg der Firmenmarktmacht sein. Anhand von Mikrodaten zum deutschen Verarbeitenden Gewerbe untersucht dieser Artikel, welche Rolle technologischer Wandel und steigende Firmenmarktmacht als Ursachen für das Fallen der Lohnquote spielen. Es zeigt sich, dass technologischer Wandel und ein Anstieg der Firmenmarktmacht, insbesondere auf Arbeitsmärkten, jeweils die Hälfte der fallenden Lohnquote im deutschen Verarbeitenden Gewerbe erklären. Daher können politische Maßnahmen, die Firmenmarktmacht reduzieren, nicht nur eine effizienzsteigernde Wirkung entfalten, sondern, als ein Nebeneffekt, auch den Anteil der Löhne an der Gesamtproduktion erhöhen.

Offshoring, Domestic Employment and Production. Evidence from the German International Sourcing Survey
Wolfhard Kaus, Markus Zimmermann
IWH Discussion Papers,
Nr. 14,
2022
Abstract
This paper analyses the effect of offshoring (i.e., the relocation of activities previously performed in-house to foreign countries) on various firm outcomes (domestic employment, production, and productivity). It uses data from the International Sourcing Survey (ISS) 2017 for Germany, linked to other firm level data such as business register and ITGS data. First, we find that offshoring is a rare event: In the sample of firms with 50 or more persons employed, only about 3% of manufacturing firms and 1% of business service firms have performed offshoring in the period 2014-2016. Second, difference-in-differences propensity score matching estimates reveal a negative effect of offshoring on domestic employment and production. Most of this negative effect is not because the offshoring firms shrink, but rather because they don’t grow as fast as the non-offshoring firms. We further decompose the underlying employment dynamics by using direct survey evidence on how many jobs the firms destroyed/created due to offshoring. Moreover, we do not find an effect on labour productivity, since the negative effect on domestic employment and production are more or less of the same size. Third, the German data confirm previous findings for Denmark that offshoring is associated with an increase in the share of ‘produced goods imports’, i.e. offshoring firms increase their imports for the same goods they continue to produce domestically. In contrast, it is not the case that offshoring firms increase the share of intermediate goods imports (a commonly used proxy for offshoring), as defined by the BEC Rev. 5 classification.

Micro-mechanisms behind Declining Labor Shares: Rising Market Power and Changing Modes of Production
Matthias Mertens
International Journal of Industrial Organization,
March
2022
Abstract
I derive a micro-founded framework showing how rising firm market power on product and labor markets and falling aggregate labor output elasticities provide three competing explanations for falling labor shares. I apply my framework to 20 years of German manufacturing sector micro data containing firm-specific price information to study these three distinct drivers of declining labor shares. I document a severe increase in firms’ labor market power, whereas firms’ product market power stayed comparably low. Changes in firm market power and a falling aggregate labor output elasticity each account for one half of the decline in labor's share.

Inflation Puzzles, the Phillips Curve and Output Expectations: New Perspectives from the Euro Zone
Alessandro Sardone, Roberto Tamborini, Giuliana Passamani
Empirica,
February
2022
Abstract
Confidence in the Phillips Curve (PC) as predictor of inflation developments along the business cycle has been shaken by recent “inflation puzzles” in advanced countries, such as the “missing disinflation” in the aftermath of the Great Recession and the “missing inflation” in the years of recovery, to which the Euro-Zone “excess deflation” during the post-crisis depression may be added. This paper proposes a newly specified Phillips Curve model, in which expected inflation, instead of being treated as an exogenous explanatory variable of actual inflation, is endogenized. The idea is simply that if the PC is used to foresee inflation, then its expectational component should in some way be the result of agents using the PC itself. As a consequence, the truly independent explanatory variables of inflation turn out to be the output gaps and the related forecast errors by agents, with notable empirical consequences. The model is tested with the Euro-Zone data 1999–2019 showing that it may provide a consistent explanation of the “inflation puzzles” by disentangling the structural component from the expectational effects of the PC.

Banking Globalization, Local Lending, and Labor Market Effects: Micro-level Evidence from Brazil
Felix Noth, Matias Ossandon Busch
Journal of Financial Stability,
October
2021
Abstract
Recent financial crises have prompted the interest in understanding how banking globalization interacts with domestic institutions in shaping foreign shocks’ transmission. This paper uses regional banking data from Brazil to show that a foreign funding shock to banks negatively affects lending by their regional branches. This effect increases in the presence of frictions in internal capital markets, which affect branches’ capacity to access funding from other regions via intra-bank linkages. These results also matter on an aggregate level, as municipality-level credit and job flows drop in exposed regions. Policies aiming to reduce the fragmented structure of regional banking markets could moderate the propagation of foreign shocks.
