Import Competition and Firm Productivity: Evidence from German Manufacturing
Richard Bräuer, Matthias Mertens, Viktor Slavtchev
World Economy,
Vol. 46 (8),
2023
Abstract
Abstract We study how different types of import competition affect firm productivity using firm-product data from German manufacturing (2000-2014). Competition from high-income countries causes affected domestic firms to increase their productivity and lower their prices. Oppositely, import competition from low-wage countries does not lead to firm productivity gains. Instead, domestic firms' sales and input usage decline. Our findings confirm the intuition of ladder models that the effect of competition depends on the "closeness" of competitors. They are in line with widespread X-inefficiencies throughout the economy, which firms reduce in response to competition from high-income countries.

Gender Pay Gap in American CFOs: Theory and Evidence
Bill Francis, Iftekhar Hasan, Gayane Hovakimian, Zenu Sharma
Journal of Corporate Finance,
Vol. 80 (June),
2023
Abstract
Studies document persistent unexplained gender-based wage gap in labor markets. At the executive level, where skill and education are similar, career interruptions and differences in risk preferences primarily explain the extant gender-based pay gap. This study focuses on CFO compensation contracts of Execucomp firms (1992–2020) and finds no gender-based pay gap. This paper offers several explanations for this phenomenon, such as novel evidence on the risk preferences of females with financial expertise and changes in the social and regulatory climate.

Loan Securitisation during the Transition to a Low-carbon Economy
Isabella Müller, Huyen Nguyen, Trang Nguyen
VoxEU CEPR,
May
2023
Abstract
Banks play a crucial role in the transition to a low-carbon economy, but they also expose themselves to climate transition risk. This column shows that banks use corporate loan securitisation to shift climate transition risk to less-regulated shadow banking entities. This behaviour affects carbon premia in loan contracts. When banks can use securitisation to manage transition risk, their climate policies that target only activities reflected in their books may not be as effective as bank regulators hope for.

Minimum Wages, Productivity, and Reallocation
Mirja Hälbig, Matthias Mertens, Steffen Müller
IZA Discussion Paper,
No. 16160,
2023
Abstract
We study the productivity effect of the German national minimum wage by applying administrative firm data. At the firm level, we confirm positive effects on wages and negative employment effects and document higher productivity even net of output price increases. We find higher wages but no employment effects at the level of aggregate industry × region cells. The minimum wage increased aggregate productivity in manufacturing. We do not find that employment reallocation across firms contributed to these aggregate productivity gains, nor do we find improvements in allocative efficiency. Instead, the productivity gains from the minimum wage result from within-firm productivity improvements only.

Minimum Wages, Productivity, and Reallocation
Mirja Hälbig, Matthias Mertens, Steffen Müller
IWH Discussion Papers,
No. 8,
2023
Abstract
We study the productivity effect of the German national minimum wage combining administrative firm datasets. We analyze firm- and market-level effects, considering output price changes, factor substitution, firm entry and exit, labor reallocation, and short- versus long-run effects. We document higher firm productivity even net of output price increases. Productivity gains are persistent in manufacturing and service sectors. The minimum wage also increased manufacturing productivity at the aggregate level. Neither firm entry and exit nor other forms of employment reallocation between firms contributed to these gains. Instead, aggregate productivity gains from the minimum wage solely stem from within-firm productivity improvements.

Do Larger Firms Exert More Market Power? Markups and Markdowns along the Size Distribution
Matthias Mertens, Bernardo Mottironi
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.
