Gender Pay Gap in American CFOs: Theory and Evidence
Bill Francis, Iftekhar Hasan, Gayane Hovakimian, Zenu Sharma
Journal of Corporate Finance,
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.

Marginal Jobs and Job Surplus: A Test of the Efficiency of Separations
Simon Jäger, Benjamin Schoefer, Josef Zweimüller
Review of Economic Studies,
Nr. 3,
2023
Abstract
We present a test of Coasean theories of efficient separations. We study a cohort of jobs from the introduction through the repeal of a large age- and region-specific unemployment benefit extension in Austria. In the treatment group, 18.5% fewer jobs survive the program period. According to the Coasean view, the destroyed marginal jobs had low joint surplus. Hence, after the repeal, the treatment survivors should be more resilient than the ineligible control group survivors. Strikingly, the two groups instead exhibit identical post-repeal separation behavior. We provide, and find suggestive evidence consistent with, an alternative model in which wage rigidity drives the inefficient separation dynamics.

Minimum Wages, Productivity, and Reallocation
Mirja Hälbig, Matthias Mertens, Steffen Müller
IZA Discussion Paper,
Nr. 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,
Nr. 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,
Nr. 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.

The Effect of Bank Failures on Small Business Loans and Income Inequality
Salvador Contreras, Amit Ghosh, Iftekhar Hasan
Journal of Banking and Finance,
January
2023
Abstract
Using variation in the timing and location of branches of failed banks we analyze its effect on income inequality. Employing a difference-in-differences specification we find that bank failures increased the GINI by 0.3 units (or 0.7%). We show that the rise in inequality is due to a decrease in the incomes of the poor that outpaces declines of the rest. We further show that individuals with lower levels of education exhibit a relatively greater decline in real wages and weekly hours worked. Exploring channels of transmission, we find income inequality is explained by a general decline in small business loans. This in turn reduces net new small business formation and their job creation capacity, a sector that hires a substantial share of low-income earners.

Paying Outsourced Labor: Direct Evidence from Linked Temp Agency-Worker-Client Data
Andres Drenik, Simon Jäger, Pascuel Plotkin, Benjamin Schoefer
Review of Economics and Statistics,
Nr. 1,
2023
Abstract
We estimate how much firms differentiate pay premia between regular and outsourced workers in temp agency work arrangements. We leverage unique Argentinian administrative data that feature links between user firms (the workplaces where temp workers perform their labor) and temp agencies (their formal employers). We estimate that a high-wage user firm that pays a regular worker a 10% premium pays a temp worker on average only a 4.9% premium, compared to what these workers would earn in a low-wage user firm in their respective work arrangements—the midpoint between the benchmarks for insiders (one) and the competitive spot-labor market (zero).
