What the literature leaves open

  • There is a lack of research on the impact of minimum wages on firms' use of clean energy. Existing studies have primarily focused on the effects of minimum wages on social equality, employment, prices, and health outcomes. The study aims to fill this gap by investigating the relationship between minimum wages and clean gas consumption in Chinese industrial firms.

    Balancing Wages and Sustainability: The Hidden Impact of Minimum Wage Policies on Clean Gas Consumption in Chinese Industrial Firms · 2026 · DOI

  • There is a need to revisit the impacts of overeducation in the Chinese labor market. The study aims to fill the gap by estimating the signaling and productivity effects of overeducation.

    The Signaling Paradox: Revisiting the Impacts of Overeducation in the Chinese Labor Market · 2024 · DOI

  • Clean gas is a relatively low-carbon fuel used in industrial production, yet little is known about how labor-market regulation is related to firms’ use of this energy input.

    Balancing Wages and Sustainability: The Hidden Impact of Minimum Wage Policies on Clean Gas Consumption in Chinese Industrial Firms · 2026 · DOI

  • Third, this research provides guidance for individuals choosing their major, governments concerned with educational resource allocation and employment opportunities, and foreign scholars with limited knowledge of China’s graduate job market.

    Chinese University Major Decision and Its Effect on Wages: Modeling Interaction Between Major Specificity and Education-Job Relevancy Using Machine Learning Approaches · 2025 · DOI

  • While existing research examined labor shortages, there remains a gap in understanding the diverse labor wage trends.

  • Limited research has explored how social policies influence cognitive function at older ages.

  • How do employment, tasks, and productivity change with robot adoption? Unlike manufacturing, little is known about these issues in the service sector, where robot adoption is expanding.

    Robots and labor in nursing homes · 2024 · DOI

  • The paper identifies a gap in the existing literature, which examines job displacement or job creation separately, but not the net employment balance across sectors. The study highlights the need to incorporate institutional factors in the analysis of AI's employment effects. The paper notes that developing economies with large informal labor markets remain underexplored in AI employment research.

    Artificial Intelligence, Automation, and Employment Dynamics: Evaluating the Balance Between Job Displacement and Job Creation · 2026 · DOI

  • The evidence above suggests that addressing the gaps in adult learning participation and skills development requires a targeted approach that recognises each country’s educational system and labour market contexts.

    Understanding Europe’s skills shortage: Patterns of participation in formal and non-formal education and training · 2026 · DOI

  • There is a need for comparative research on employment trends in the United States, Canada, and Mexico. Prior research has not fully examined the impact of institutional capacity, informality, and human capital investment on labor-market resilience.

    Brief Report: Comparative Analysis of Employment Trends in the United States, Canada, and Mexico · 2026 · DOI

  • The paper suggests that future research should investigate the diffusion of innovations in other contexts, such as the diffusion of technological innovations. The paper also suggests that future research should examine the role of power dynamics and social networks in shaping innovation diffusion.

    Innovation Diffusion in Large, Heterogeneous Populations · 2026 · DOI

  • The paper notes that prior work has focused on social learning, institutional bandwagons, and competitive pressures, but has not fully considered the radicalness of innovations and core-periphery differentials.

    Innovation Diffusion in Large, Heterogeneous Populations · 2026 · DOI

  • Future research should address the limitation of bivariate models and consider multivariate analysis. The paper suggests that future research should focus on the educational composition of the NEET population. Further research is needed to understand the dynamics of the NEET phenomenon in Romania.

    NEET, But Not the Same: The Widening Educational Divide Between NEETs and EETs in Romania · 2026 · DOI

  • The existing literature has not fully addressed the issue of the educational composition of the NEET population. The paper seeks to fill this gap by applying and extending the Δedu indicator.

    NEET, But Not the Same: The Widening Educational Divide Between NEETs and EETs in Romania · 2026 · DOI

  • In sum, rather than opposing skill- and occupation-based perspectives, future research should explore their interaction, particularly how real or perceived differences in skills can be used to legitimize socio-economic inequalities between occupational groups (Braverman 1998).

    Are Occupations “Bundles of Skills”? Identifying Latent Skill Profiles in the Labor Market Using Topic Modeling · 2026 · DOI

  • The need to consider observable features like education, occupational type, and geographic location.

    PUBLIC AND PRIVATE SECTOR WAGE DIFFERENTIALS: EMPIRICAL EVIDENCE FROM TÜRKİYE · 2026 · DOI

  • The lack of understanding of public-private sector wage differentials in Türkiye. The need to examine the change in the public-private wage gap over time.

    PUBLIC AND PRIVATE SECTOR WAGE DIFFERENTIALS: EMPIRICAL EVIDENCE FROM TÜRKİYE · 2026 · DOI

  • The findings should be interpreted in light of the limitation that the training provided to participants may have influenced their responses. Participants' expertise in economics, labor markets, and macroeconomic models is limited.

    Effects of STEM Education on Unemployment Types: An Applied Science Case Study · 2026 · DOI

  • Finally, the review of the existing literature on the employment effects of the minimum wage shows that, as in other countries, the results are mixed with modest negative or no effects.

  • While firms in many developed countries increasingly rely on workers with nonstandard contracts, the underlying economic factor distinguishing workers on standard contracts from those on nonstandard contracts is poorly understood.

    How do firms attain internal and external flexibility of employment? · 2024 · DOI

  • Indian returns-to-schooling estimates remain dominated by OLS approaches that may be substantially biased. The staggered DPEP roll-out is a credible source of exogenous variation that has not been exploited in wage regressions. Modern instrument-validity diagnostics have not been routinely applied in Indian work.

    Returns to Education in India: An Instrumental Variables Analysis Using the District Primary Education Programme as a Source of Exogenous Variation in Schooling · 2026 · DOI

  • Examine the impact of other factors, such as globalization and demographic shifts, on employment trends.

  • Finally, we discuss policies to reduce mismatch and identify open questions for future research.

    Mismatch in the 21st century: An overview · 2026 · DOI

  • The research presents mixed findings on the employment effects of technology: firms with high technological intensity tend to employ fewer high-skilled workers, suggesting complementarity between current technology and low-skilled labour.

    Disruptive Technology, Skills and Tasks: Evidence from Indonesia · 2025 · DOI

  • This journey not only takes us back in time but also points to potential avenues for future research and open questions that lie ahead.
