From Labor to Intermediates: Firm Growth, Input Substitution, and Monopsony

IWH Discussion Papers,
No. 24,

Abstract
We document and dissect a new stylized fact about firm growth: the shift from labor to intermediate inputs. This shift occurs in input quantities, cost and output shares, and output elasticities. We establish this fact using German firm-level data and replicate it in administrative firm data from 11 additional countries. We also document these patterns in micro-aggregated industry data for 20 European countries (and, with respect to industry cost shares, for the US). We rationalize this novel regularity within a parsimonious model featuring (i) an elasticity of substitution between intermediates and labor that exceeds unity, and (ii) an increasing shadow price of labor relative to intermediates, due to monopsony power over labor or labor adjustment costs. The shift from labor to intermediates accounts for one half to one third of the decline in the labor share in growing firms (the remainder is due to wage markdowns and markups) and rationalizes most of the labor share decline in growing industries.

Regional Industrial Effects in Germany from a Potential Gas Deficit
Robert Lehmann, Christoph Schult
German Economic Review,
No. 3,
2024
Abstract
We estimate potential regional industrial effects in case of a threatening gas deficit. For Germany, the reduction leads to a potential decrease in industrial value added by 1.6 %. The heterogeneity across German states is remarkable, ranging from 2.2 % for Rhineland-Palatinate to 0.7 % for Hamburg. We emphasize the need for regional input-output tables to conduct economic analysis on a sub-national level, particularly when regional industrial structures are heterogeneous. The approximation with national figures can lead to results that differ both in magnitude and relative regional exposure. Our findings highlight that more accurate policy guidance can be achieved by improving the regional database.

International Trade Barriers and Regional Employment: The Case of a No-Deal Brexit
Hans-Ulrich Brautzsch, Oliver Holtemöller
Journal of Economic Structures,
No. 11,
2021
Abstract
We use the World Input–Output Database (WIOD) combined with regional sectoral employment data to estimate the potential regional employment effects of international trade barriers. We study the case of a no-deal Brexit in which imports to the United Kingdom (UK) from the European Union (EU) would be subject to tariffs and non-tariff trade costs. First, we derive the decline in UK final goods imports from the EU from industry-specific international trade elasticities, tariffs and non-tariff trade costs. Using input–output analysis, we estimate the potential output and employment effects for 56 industries and 43 countries on the national level. The absolute effects would be largest in big EU countries which have close trade relationships with the UK, such as Germany and France. However, there would also be large countries outside the EU which would be heavily affected via global value chains, such as China, for example. The relative effects (in percent of total employment) would be largest in Ireland followed by Belgium. In a second step, we split up the national effects on the NUTS-2 level for EU member states and additionally on the county (NUTS-3) level for Germany. The share of affected workers varies between 0.03% and 3.4% among European NUTS-2 regions and between 0.15% and 0.4% among German counties. A general result is that indirect effects via global value chains, i.e., trade in intermediate inputs, are more important than direct effects via final demand.

Short-term Economic Effects of a "Brexit" on the German Economy

Abstract
Viele Fragen rund um den Brexit sind weiterhin offen. Es kann nicht ausgeschlossen werden, dass sich Großbritannien und die Europäische Union nicht auf einen Austrittsvertrag einigen können. Dann könnte es zu einem sogenannten harten Brexit (No-Deal Brexit) kommen. Wir haben die kurzfristigen Effekte eines harten Brexit für die deutsche Wirtschaft untersucht. Effekte über den Handelskanal werden zunächst auf Basis einer Input-Output-Analyse der internationalen und sektoralen Verflechtungen auf 0,3% in Relation zum Bruttoinlandsprodukt geschätzt. Diese Größenordnung ergibt sich auch aus dem internationalen Konjunkturmodell des IWH, mit dem auch makroökonomische Rückwirkungen berücksichtigt werden. Mit einem harten Brexit entstünde neben den Handelsbarrieren ein erhebliches Verunsicherungspotenzial für Unternehmer und private Haushalte. Dies wirkt sich nachfrageseitig negativ auf die Investitionstätigkeit und den privaten Verbrauch aus. Für sich genommen belaufen sich diese Effekte auf 0,1% des Bruttoinlandsproduktes. Insgesamt könnte das deutsche Bruttoinlandsprodukt in den ein bis zwei Jahren nach einem harten Brexit um mehrere zehntel Prozentpunkte gedämpft werden. Am stärksten wäre wohl die Automobilbranche betroffen. Empfehlungen für diskretionäre konjunkturpolitische Maßnahmen, die auf die Dämpfung der kurzfristigen gesamtwirtschaftlichen Effekte oder auf einzelne Wirtschaftszweige abzielen, lassen sich daraus nicht ableiten. Die automatischen Stabilisatoren sind angesichts der erwarteten Größenordnung der Effekte ausreichend.
