Purpose

This empirical study aims to examine the COVID impact on the rate of return to schooling in 20 US industries.

Design/methodology/approach

An extended Mincer earnings equation with the COVID dummy variable and dummy interactive terms is used to examine the COVID effect on the rate of return to schooling for different industries. We use Heckman selection model to account for sample selection bias.

Findings

During COVID years, the change in the wage differential between college-and-above and below-college workers is different for industries, which leads to different changes in the rate or return to schooling among the 20 industries. During COVID, the rate of return to schooling increased for seven industries, decreased for seven industries and remained the same for six industries.

Originality/value

There is a lack of empirical tests of recession effects on the rate of return to schooling focusing on industry differentials. This study fills the research gap in this field. Our results will contribute to the ongoing discussion of the COVID impact on wages and returns from human capital investment.

Purpose

This study aims to examine the relationship between information and communication technology (ICT) and economic growth in all organization for economic co-operation and development (OECD) countries.

Design/methodology/approach

This paper employs annual panel data together with fixed-effects (FE), random effects (RE), fully modified ordinary least squares (FMOLS), dynamic ordinary least squares (DOLS) and generalized method of moments (GMM) estimators for production function estimation.

Findings

The results indicate that ICTs, non-ICT (NICT) capital services and employment significantly and positively affect economic growth.

Practical implications

Information is an important driving force behind economic growth and productivity, and communication technologies have made it more accessable. Also, many countries aimed to invest in ICT to improve their economic growth and productivity. However, these investments failed to produce the expected outcome for some years and countries.

Originality/value

To our knowledge, no study examines the ICT and growth relation in all OECD countries for 2000–2018 period. We intend to fill this gap by examining whether or not the expected returns from ICT investment are achieved in all OECD countries between 2000 and 2018.

Purpose

This paper provides novel evidence on the role of gender in the performance of university students, which is particularly relevant to the debate on the performance of female students in science, technology, engineering and mathematics (STEM) subjects.

Design/methodology/approach

Our approach relies on the metafrontier approach proposed by Huang et al. (2014), which measures students' efficiency within a given faculty and the impact of the faculty’s technology on students’ efficiency. We use a sample of 53,159 first-year students in 8 faculties from a large university in southern Italy from 2002–2003 to 2010–2011.

Findings

Students’ efficiency is relatively low, reflecting an essential role of unobserved heterogeneity. The different technologies of somewhat similar faculties have minimal impact on efficiency. There is a performance gap against women in five faculties, which on average is strongest for the faculties in the pure and applied science area. This gap increases with the proportion of female students and decreases with female lecturers.

Practical implications

The metafrontier has the benefit of providing relevant policy information on the drivers of student success by relying on data that universities routinely generate and preserve.

Originality/value

The stochastic metafrontier approach allows us to separate the group-specific frontiers from the metafrontier, yielding a decomposition of the efficiency scores of various faculties into technical efficiency scores and technological gaps.

Purpose

This study has empirically investigated the impacts of climate change on agricultural productivity worldwide, considering the ranking of agriculture productivity. Additionally, the study has estimated the extent to which climate change favoured agriculture productivity from a global perspective.

Design/methodology/approach

The study prepared a suitable econometric model and employed the quantile panel Autoregressive Distributed Lag technique with a two-step Error Correction Mechanism to assess the influence of global warming on worldwide agrarian productivity.

Findings

The estimated results provide evidence for the nonlinear impacts of climate change on agriculture productivity across all quantiles. Moreover, threshold levels of average annual temperature rise with the improvement of agricultural productivity, depicting that low-productive areas are highly vulnerable to global warming. Additionally, agricultural inputs like labour, capital and irrigated land are positively related to agricultural productivity, with relatively substantial marginal productivity in highly productive regions. Nevertheless, technological innovations are found to be more productive in low-productive areas.

Practical implications

Policymakers should prioritize region-specific climate-smart agriculture by targeting policies to increase agricultural productivity and minimize the effects of climate change on food security and nutrition.

Originality/value

Despite significant research in this area, there remains a knowledge gap on the nature of this relationship, especially regarding productivity thresholds under warming. The study aims to fill this gap, offering valuable insights to guide policy actions and adaptation strategies to mitigate the adverse impacts of climate change on agriculture productivity.

Purpose

The paper is devoted to modeling a pricing policy of competitive firms in a “closed” economy framework.

Design/methodology/approach

The proposed model can be regarded as an analog to CGE model and is based on the intersectoral balance methodology incorporating linear demand functions for goods and services.

Findings

By performing different model experiments, we show that a certain degree of competition can bring more profit to all competing firms, than in case of complete absence of such competition, what is also supported by empirical investigation. This finding implies that monopolies may perform worse than competitive firms, what contradicts with the modern provisions of economic theory, stating that monopoly is the most lucrative type of market structure for a producer. The discovered effect occurs due to the aggressive pricing policy, adopted by monopolies, spurring up the inflation spiral, which is most obvious if monopolies are strongly interdependent in terms of production matrix. This inflation spiral drives prices too high, what negatively reflects on firms’ costs and, consequently, results in monopolies receiving less profit.

Originality/value

The proposed model can also be useful for understanding and assessing various economic consequences after different external or internal shocks, what is especially crucial when conducting monetary or fiscal policy.

Purpose

Whether environmental, social and governance (ESG) factors are a curse or a blessing in the run for performance is still a burning issue. This is all the more true for banks, as their call for action in ESG dimensions clashes with evidence of scandals. As a more aligned to reality view, we propose to regard the mistreatment of ESG issues, both theoretically and empirically, as an undesirable output of banks' everyday activity. Empirically, we question whether 128 leading banks worldwide neglected the minimisation of ESG controversies (ESGC) in pursuing traditional productive efficiency, over the timespan 2011–2021.

Design/methodology/approach

To our end, we use oriented distance functions according to the nonparametric efficiency approach of data envelopment analysis (DEA). This framework accounts for undesirable outputs.

Findings

Being inefficient in the ESGC domain is not a necessary evil to achieve productive efficiency. Instead, incurring in higher ESGC negatively affects productive efficiency, by causing future decrease of reputation and performance.

Originality/value

We propose a new paradigm of banks’ activity and related efficiency evaluation. In so doing, we favour a real dimension of banks’ engagement in ESG concerns.

Purpose

In this paper, the impact of the 2004 European Union accession on income inequalities within New Member States is analyzed.

Design/methodology/approach

An empirical analysis is conducted with nine New Member States over the period 1991–2015, with 55 economies serving as a control group. The newly introduced (by de Chaisemartin and D’Haultfœuille, 2023) method belonging to the family of difference-in-differences (DID) estimators is applied to allow for multiple non-binary treatments.

Findings

While accession to the European Union had a positive and significant impact on the market and net Gini coefficients in the treated countries, no evidence of the impact of accession on redistribution was found. Single-unit estimates signal that income inequalities rose due to EU membership in some member countries; the most convincing evidence shows that income distribution in Latvia was especially affected.

Originality/value

The author applied the method which addresses the presence of multiple non-binary treatments. Full-fledged membership was preceded by association status, and accession to the EU was accompanied or followed by engagement in other layers of integration (European Monetary Union and Schengen Area). Controlling for these features, the author was able to assess whether the pure EU effect contributed to increases in income inequalities.

Purpose

This paper aims to examine the profitability of Islamic banks benefits from economic freedom and its subcomponents.

Design/methodology/approach

This study uses a sample of 41 Islamic banks from the Organization of Islamic Cooperation (OIC) Countries selected from 2010–2020. It conducts an empirical approach based on the System Generalized Method of Moments (SGMM).

Findings

Overall, economic freedom has a substantial impact on the profitability of Islamic banks. We then investigate the relationship between the subcomponents of economic freedom and the profitability of Islamic banks. The study’s breakdown components suggest that financial and investment freedoms are favorable indicators, while business and monetary freedoms have a negative effect.

Practical implications

This research can serve as a guideline for Islamic bank management in terms of maintaining performance. The results of this study provide policy implications for the government to offer friendly regulations for economic actors to engage in financial transactions by looking at the economic freedom sub-component.

Originality/value

To the best of the authors' knowledge, the study of the role of economic freedom in Islamic banking performance is limited, particularly in the context of OIC Countries.

Purpose

The impact of digitalisation on smaller firms remains sparsely studied across emerging economies. The paper aims to examine the relationship between digital adoption and multiple performance parameters of micro, small and medium enterprises (MSME) in a prominent emerging economy.

Design/methodology/approach

The study employs data from the World Bank Enterprise Survey (WBES) 2022, capturing 9,024 Indian MSME firms spread across the country. Performance indicators are derived from growth in sales, employment and labour productivity (LPROD). Multiple regression estimates are derived that also correct for sample selection bias using Heckman’s two-step process.

Findings

Digital proliferation is found to increase as firms mature up in terms of age, size and constitution. A significant difference could also be observed in business performance across digital and non-digital businesses, with sales growth (SG) and productivity higher for digital firms. Digital financial variables are found to have a significant impact on SG but not as much in the case of employment growth and LPROD. The results are robust to correction for sample selection bias in digital adoption using inverse mills ratio (IMR).

Practical implications

The study highlights digital adoption gaps across various strata of MSMEs, highlighting lower adoption when firms are younger, smaller and lacking formal constitutional setup. Digital variables indicating positive association with SG highlight the need for concerted efforts at the public policy level for building appropriate skills and infrastructure for micro and small enterprises to boost their digital adoption to promote growth.

Originality/value

There is a lack of micro-level empirical evidence measuring the impact of advanced digital technology usage on multiple aspects of enterprise performance amongst micro and small firms. The study deploys unique digital variables including TReDS and use of online credit applications to assess the impact on business performance. The findings provide insights for practice and public policy, besides making the case for a higher focus on launching digital initiatives for smaller enterprises.

Purpose

Since February 2022, the conflict between Ukraine and Russia has significantly influenced global financial markets, altering investor behavior and increasing market volatility. Western countries’ sanctions on Russia have influenced market uncertainty. Academic literature has deeply investigated the market’s reaction to the conflict and demonstrated a diverse range of impacts. Our study delves into how corporate decisions to remain in or exit Russia during the conflict influence analyst sentiment.

Design/methodology/approach

Leveraging data on analysts' revision scores (ARS) from Eikon, Refinitiv, our analysis underscores the importance of analysts during periods of uncertainty (Kacperczyk and Seru, 2007; Loh and Stulz, 2018). Using static and dynamic panel analysis, we examine the impact of Russia exposure on ARS while controlling for key variables.

Findings

Companies that retain a presence in Russia tend to enhance the overall ARS score, contributing to increased optimism among analysts regarding forecasts for the firms in question. Controlling for endogeneity and underlying dynamics in ARS does not alter the main findings. All in all, the results confirm the absence of an impact on the companies' returns post-announcement to continue or leave Russia after the start of the conflict (Balyuk and Fedyk, 2023).

Originality/value

This research sheds light on the complex relationship between geopolitical events, corporate decisions and investor sentiment, offering valuable insights for stakeholders, policymakers and regulators.
