The Impact of Worker-Firm Interactions on the Gender Wage Gap: Evidence from Brazilian Administrative Data

Core Concepts

Traditional models of the gender wage gap, which assume additive separability of worker and firm characteristics, underestimate the role of firms in contributing to wage disparities. This paper demonstrates that accounting for worker-firm interactions, particularly the "match effect" or complementarities, reveals a significant and previously uncaptured source of the gender wage gap.

Abstract

• Bibliographic Information: Sant’Anna, H. (2024). Gender Differences in Comparative Advantage Matches: Evidence from Linked Employer-Employee Data. [Working Paper]. University of Georgia.
• Research Objective: This paper investigates the role of worker-firm interactions, specifically complementarity effects, in explaining the gender wage gap. The author argues that traditional additive separable models, like the AKM, fail to capture the full impact of firms on wage disparities.
• Methodology: The study utilizes a large linked employer-employee dataset (RAIS) from Brazil, spanning 2010 to 2017. The author employs a two-step clustering approach based on Bonhomme, Lamadon, and Manresa (2019) to group firms and workers into latent classes and types, respectively. This method allows for the identification of "match effects" or complementarities that arise from specific worker-firm pairings.
• Key Findings: The research reveals that "complementarity effects" account for approximately 17% of the gender wage gap in Brazil. These effects are more pronounced in larger firms, high human capital occupations (STEM, managerial roles), and increase with age and education. The study also finds that women are less likely to be employed by firms offering higher returns to human capital and firm-specific premiums, resulting in a larger "sorting" effect (37.5% of the gap) than previously estimated. Additionally, a "bargaining" effect (8.3% of the gap) persists, indicating that women receive lower wages even within the same firm and worker type.
• Main Conclusions: The paper concludes that worker-firm interactions, particularly complementarities and sorting, play a crucial role in explaining the gender wage gap. Traditional models underestimate the contribution of firms to these disparities. The findings highlight the importance of considering assortative matching in the labor market when designing policies to address wage inequality.
• Significance: This research significantly contributes to the literature on gender wage disparities by providing a more nuanced understanding of the role of firms. It moves beyond traditional additive separable models and highlights the importance of considering worker-firm interactions.
• Limitations and Future Research: The study focuses on the formal labor market in Brazil, limiting generalizability to other contexts. Future research could explore the role of non-monetary benefits and investigate the underlying mechanisms driving the observed sorting and complementarity effects.

Quotes

"These “complementarity effects” account for approximately 17% of the gender wage gap. Larger firms, high human capital, STEM degrees, and managerial roles are closely related to it."
"I also find women are less likely to be employed by firms offering higher returns to both human capital and firm-specific premiums, resulting in a significantly larger firm contribution to the gender wage gap than previously estimated."
"Combined, these factors explain nearly half of the overall gender wage gap, suggesting the importance of understanding firm-worker matches in addressing gender-based pay disparities."

Deeper Inquiries

How might policies aimed at promoting female entrepreneurship or supporting women-led businesses contribute to narrowing the gender wage gap, considering the findings of this research?

This research highlights the significant role of assortative matching and firm-specific premiums in driving the gender wage gap. Policies promoting female entrepreneurship or supporting women-led businesses could contribute to narrowing the gap in several ways:

Creating higher-paying firms: Women-led businesses could potentially offer more equitable pay structures and close the bargaining gap, leading to higher wages for women overall. This effect could be amplified if these businesses grow and become part of the higher-paying firm classes, directly challenging the concentration of men in such firms.
Shifting sorting patterns: By creating more firms led by women, the labor market might see a shift in the sorting of women towards higher-paying firm classes. This shift could be driven by both supply (more high-paying firms led by women) and demand (potential preference for women to work for women-led companies).
Breaking down gender norms: Successful female entrepreneurs can serve as role models, challenging traditional gender norms and inspiring other women to pursue higher-paying careers and leadership roles. This could lead to a reduction in occupational segregation and an increase in women's representation in fields like STEM and management, where complementarity effects are more pronounced.
Offering alternative career paths: Entrepreneurship offers an alternative career path for women who face barriers in traditional workplaces. This can be particularly impactful for women in occupations with limited upward mobility or those seeking greater work-life balance, a factor often cited by Goldin (2014).
However, it's crucial to acknowledge potential limitations:

Access to capital: Women entrepreneurs often face greater challenges in accessing capital, which could limit the growth and wage competitiveness of their businesses.
Sectoral concentration: Women-led businesses might be concentrated in sectors with inherently lower wages, limiting their impact on the overall wage gap.
Therefore, policies supporting female entrepreneurship should address these limitations by providing access to funding, networks, and training, while also promoting equal pay practices within these businesses.

Could differences in risk aversion or career aspirations between genders, rather than solely labor market frictions, contribute to the observed sorting patterns in the Brazilian labor market?

While the research focuses on labor market frictions, differences in risk aversion and career aspirations between genders could indeed contribute to the observed sorting patterns.

Risk Aversion: If women, on average, are more risk-averse than men, they might be less likely to pursue careers in volatile sectors or firms with significant pay-for-performance structures, even if these offer higher earning potential. This could lead to a concentration of women in lower-paying firm classes with more stable wages.
Career Aspirations: Societal norms and expectations can shape career aspirations differently for men and women. Women might prioritize different job characteristics, such as work-life balance or social impact, over higher salaries. This could lead them to self-select into occupations or firms that align with these priorities, even if they are associated with lower wages.
It's important to note that these factors are complex and intertwined with existing labor market structures. For example:

Discrimination: Women might be discouraged from pursuing certain career paths due to conscious or unconscious bias, leading them to adjust their aspirations based on perceived limitations.
Family responsibilities: Women often bear a disproportionate share of family responsibilities, which can impact their risk tolerance and career choices.
Therefore, disentangling the influence of individual preferences from structural barriers is challenging. Further research could explore:

Controlled experiments: To isolate the impact of risk aversion and career aspirations on job choices, holding other factors constant.
Qualitative data: In-depth interviews or surveys could provide insights into the motivations and decision-making processes of men and women in the Brazilian labor market.
Understanding the interplay between individual preferences and labor market dynamics is crucial for designing effective policies to address the gender wage gap.

If technology continues to reshape the labor market and potentially exacerbate income inequality, how can we ensure that efforts to close the gender wage gap remain effective and adaptable to these evolving dynamics?

The evolving technological landscape presents both challenges and opportunities for closing the gender wage gap. Here are some strategies to ensure efforts remain effective:

Investing in STEM education and skills development for women: As technology creates new opportunities in STEM fields, it's crucial to equip women with the necessary skills to thrive in these roles. This includes early interventions in education, scholarships, and retraining programs for women transitioning careers.
Promoting women in leadership positions within tech sectors: Addressing the underrepresentation of women in leadership roles within tech companies is crucial for influencing hiring practices, pay equity, and workplace culture. This can be achieved through mentorship programs, leadership training, and targets for female representation in executive positions.
Anticipating and mitigating automation's impact on women: Research suggests that automation might disproportionately displace women from certain occupations. Proactive policies, such as reskilling programs and social safety nets, can help women adapt to these changes and transition into new roles.
Ensuring pay transparency and algorithmic fairness: As algorithms increasingly influence hiring and compensation decisions, it's crucial to ensure transparency and fairness in these systems. This includes auditing algorithms for bias, promoting diverse teams developing these technologies, and establishing clear guidelines for their ethical use.
Supporting women entrepreneurs in the tech sector: Encouraging and supporting women-led startups in technology can create more equitable workplaces and contribute to closing the wage gap within this rapidly growing sector. This includes access to funding, mentorship, and networks specifically designed for women tech entrepreneurs.
Adapting labor market policies to the changing nature of work: Traditional labor protections and social safety nets might need adjustments to accommodate the rise of gig work and platform-based employment, ensuring that women participating in these new forms of work have access to fair wages and benefits.
By proactively addressing the potential impact of technology on the gender wage gap and adapting existing strategies, we can leverage technological advancements to create a more equitable and inclusive labor market for all.
