Micro-mechanisms behind Declining Labor Shares: Rising Market Power and Changing Modes of Production

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.

Corporate Loan Spreads and Economic Activity
Anthony Saunders, Alessandro Spina, Sascha Steffen, Daniel Streitz
Abstract
We use secondary corporate loan-market prices to construct a novel loan-market-based credit spread. This measure has considerable predictive power for economic activity across macroeconomic outcomes in both the U.S. and Europe and captures unique information not contained in public market credit spreads. Loan-market borrowers are compositionally different and particularly sensitive to supply-side frictions as well as financial frictions that emanate from their own balance sheets. This evidence highlights the joint role of financial intermediary and borrower balance-sheet frictions in understanding macroeconomic developments and enriches our understanding of which type of financial frictions matter for the economy.

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.

Organised Labour, Labour Market Imperfections, and Employer Wage Premia
Sabien Dobbelaer, Boris Hirsch, Steffen Müller, Georg Neuschäffer
CESifo Working Paper,
Nr. 8739,
2020
publiziert in: ILR Review
Abstract
This paper examines how collective bargaining through unions and workplace co-determination through works councils shape labour market imperfections and how labourmarket imperfections matter for employer wage premia. Based on representative Germanplant data for the years 1999{2016, we document that labour market imperfections arethe norm rather than the exception. Wage mark-downs, that is wages below the marginalrevenue product of labour rooted in employers' monopsony power, are the most prevalentoutcome. We further nd that both types of organised labour are accompanied by asmaller prevalence and intensity of wage mark-downs whereas the opposite holds for wagemark-ups, that is wages above the marginal revenue product of labour rooted in workers'monopoly power. Finally, we document a close link between our production-based labourmarket imperfection measures and employer wage premia. The prevalence and intensityof wage mark-downs are associated with a smaller level and larger dispersion of premiawhereas wage mark-ups are only accompanied by a higher premium level.

Promoting Higher Productivity in China — Does Innovation Expenditure Really Matter?

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.
