Do Larger Firms Exert More Market Power? Markups and Markdowns along the Size Distribution

IWH-CompNet Discussion Papers,
No. 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.

What Does Codetermination Do?
Simon Jäger, Shakked Noy, Benjamin Schoefer
ILR Review,
No. 4,
2022
Abstract
The authors provide a comprehensive overview of codetermination, that is, worker representation in firms’ governance and management. The available micro evidence points to zero or small positive effects of codetermination on worker and firm outcomes and leaves room for moderate positive effects on productivity, wages, and job stability. The authors also present new country-level, general-equilibrium event studies of codetermination reforms between the 1960s and 2010s, finding no effects on aggregate economic outcomes or the quality of industrial relations. They offer three explanations for the institution’s limited impact. First, existing codetermination laws convey little authority to workers. Second, countries with codetermination laws have high baseline levels of informal worker voice. Third, codetermination laws may interact with other labor market institutions, such as union representation and collective bargaining. The article closes with a discussion of the implications for recent codetermination proposals in the United States.

Handelsschocks, Arbeitsmärkte und Wohlstand während der ersten Globalisierung
Richard Bräuer, Wolf-Fabian Hungerland, Felix Kersting
Wirtschaft im Wandel,
No. 1,
2022
Abstract
Dieser Beitrag untersucht Deutschland in der ersten Globalisierung in den Jahrzehnten vor dem Ersten Weltkrieg. Damals erlebte das Deutsche Reich eine massive Zunahme von Getreideimporten aus Amerika. Wir vergleichen Landkreise, die auf die importierten Getreidesorten spezialisiert waren, mit Kreisen, die andere landwirtschaftliche Güter hergestellt haben. Unsere Resultate zeigen, dass viele Arbeitskräfte die Kreise verlassen, in denen vom Handelsschock betroffene Produkte hergestellt wurden. Allerdings bleiben die in modernen Volkswirtschaften beobachteten negativen Effekte auf Einkommen pro Kopf und Sterblichkeit aus, auch eine politische Radikalisierung findet nicht statt. Unsere Ergebnisse legen nahe, dass die Migrationsbewegungen negative wirtschaftliche und in der Folge auch politische Auswirkungen abfedern. Damals verließen etwa viermal so viele Einwohner ihren Landkreis nach einem Handelsschock wie in vergleichbaren Situationen in den heutigen USA.

The Financial Channel of Wage Rigidity
Benjamin Schoefer
Econometrics Laboratory (EML),

2022
Abstract
I propose a financial channel of wage rigidity. In recessions, rigid average wages squeeze cash flows, forcing firms to cut hiring due to financial constraints. Indeed, empirical cash flows and profits would turn acyclical if wages were only moderately more procyclical. I study this channel in a search and matching model with financial constraints and wage rigidity among incumbent workers (but flexible new hires’ wages). While neither feature generates amplification individually, their interaction can account for much of the empirical labor market fluctuations—breaking the neutrality of incumbents’ wages for hiring, and showing that financial amplification of business cycles requires wage rigidity.

Globalization, Productivity Growth, and Labor Compensation
Christian Dreger, Marius Fourné, Oliver Holtemöller
IWH Discussion Papers,
No. 7,
2022
Abstract
We analyze how changes in international trade integration affect productivity and the functional income distribution. To account for endogeneity, we construct a leaveout measure for international trade integration for country-industry pairs using international input-output tables. Our findings corroborate on the country-industry level that international trade integration increases productivity. Moreover, we show that both trade in intermediate inputs and trade in value added is associated with lower labor shares in emerging markets. For advanced countries, we document a positive effect of trade in value added on the labor share of income. Further, we show that the effects on productivity and labor share are heterogeneous across different sectors. Finally, we discuss the implications of our results for a possible throwback in international trade integration due to experiences from recent crises.

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.

Labor Market Power and the Distorting Effects of International Trade
Matthias Mertens
International Journal of Industrial Organization,
January
2020
Abstract
This article examines how final product trade with China shapes and interacts with labor market imperfections that create market power in labor markets and prevent an efficient market outcome. I develop a framework for measuring such labor market power distortions in monetary terms and document large degrees of these distortions in Germany's manufacturing sector. Import competition only exerts labor market disciplining effects if firms, rather than employees, possess labor market power. Otherwise, increasing export demand and import competition both fortify existing distortions, which decreases labor market efficiency. This widens the gap between potential and realized output and thus diminishes classical gains from trade.
