This chapter reviews the econometric approaches typically used to deal with the spike of zeros when modelling non-negative outcomes such as expenditures, income, or consumption. Relying on the assumptions of selection on observables for evaluating a policy or treatment, this chapter discusses other issues that arise with spikes of zeros in the data, including the analyst's choice between full information versus quasi-likelihood methods, considering whether observed zeros are true or masking more complex behavioural decisions, and dealing with zeros that arise due to self-selection. This chapter ends with discussions of empirical strategies to deal with these behavioural assumptions and a brief review of the literature where such strategies were employed.

This paper aims to investigate whether female directors of companies are more likely to appoint audit firms (AFs) with women in high-level positions adopting monitoring, reputation and homophily theories.

The paper uses ordinary least square to test the hypotheses using a unique hand-collected data set obtained from various sources. To mitigate potential endogeneity and selection bias issues, system generalized method of moments (GMM) and Heckman two-stage procedures are used. Additionally, alternative independent and dependent variables are created to strengthen the validity of main results.

The findings show that female directors are more likely to appoint AFs with women in high-level positions. Non-independent female directors, compared to independent ones, are particularly inclined to do so. These results are supported by further analyses using system GMM, Heckman two-stage procedures and alternative variables.

This study examines how female directors influence companies’ choices of AFs with women in high-level positions. It introduces unique audit firm governance proxies and variables specific to developing countries. The study also controls for various corporate governance, company and audit firm characteristics.

This study aims to assess if the voluntary reporting of adjusted earnings before interest, taxes, depreciation and amortization (EBITDA), a widely used non-generally accepted accounting principles (GAAP) measure, has effects on information asymmetry and value relevance and how the adjustments to GAAP earnings made to derive it contribute to these effects. This study focuses on firms from two countries with contrasting institutional settings, Canada and France.

Relying on multivariate analyses and using Heckman’s procedure to address the sample self-selection issue, this study first estimates the likelihood of a firm to report adjusted EBITDA. Then, this study examines if adjusted EBITDA, as well as the adjustments made to GAAP earnings to derive adjusted EBITDA (adjustments), affect a firm’s information asymmetry and its value. These adjustments are essentially GAAP-grounded items that are discarded by management to derive non-GAAP adjusted EBITDA. The dependent variables are share price volatility, as a proxy for information asymmetry, alongside market-to-book and stock market return as indicators of value.

In terms of the used sample, results suggest that Canadian firms are much more likely to report adjusted EBITDA than French firms. Chief executive officer (CEO) attributes (CEO power) appears to increase such likelihood. Moreover, for both Canadian and French firms, adjusted EBITDA is associated with reduced stock market volatility, an indication of lower information asymmetry, as well as higher market-to-book and returns, suggesting value relevance. The results also indicate that investors view the adjustments to GAAP earnings made by management to derive adjusted EBITDA as not value relevant (similar to noise). The GAAP-grounded elements that management discard to derive adjusted EBITDA actually increase information asymmetry.

This study adds to prior research on the interface between a CEO attributes and governance and non-GAAP reporting. This study also provides evidence that, despite very different institutional settings, non-GAAP reporting conveys relevant information to capital markets’ participants in both France and Canada. Hence, a country’s institutional setting may have a differential impact on the disclosure choice but not on the resulting value relevance of such disclosure. Finally, this study extends the non-GAAP literature by examining the value relevance of a widely used yet under-researched measure, adjusted EBITDA.

Young graduates in Morocco are encountering an increasingly challenging labor market environment. Confronted with intense competition, job insecurity, and unclear career trajectories, many find themselves in low-skilled positions despite possessing relevant qualifications. This issue is particularly pronounced among vocational training graduates, who experience professional downgrading at a rate three times higher (33.6%) compared to their peers from general education (11.6%) (HCP, 2018). Our study aims to investigate professional downgrading among young vocational training graduates in Morocco, focusing on the factors contributing to this phenomenon and identifying potential solutions to address it.

Our study is based on the insertion and career path survey conducted by the Department of Professional Training with graduates of professional training programs in Morocco. For this edition, the survey was conducted in 2020, encompassing all 31,498 graduates of the 2016 professional training programs. The Heckman self-selection model is employed to analyze and explore various dimensions of downgrading. Factors such as gender, age, marital status, parental education, and the choice of vocational training field are scrutinized to understand their influence on downgrading.

The study reveals several key findings: Women exhibit a lower probability of professional downgrading compared to men. Young graduates are more vulnerable to downgrading, emphasizing the necessity for career guidance and mentorship programs to facilitate their entry into the job market. Marital status plays a role, with married individuals having a higher likelihood of downgrading. Parental education, particularly that of mothers, proves critical in preventing subjective downgrading of vocational training graduates, highlighting the need for adult literacy and education programs. The effectiveness of the National Agency for the Promotion of Employment and Competencies (ANAPEC) programs in preventing downgrading among vocational training graduates is questioned, suggesting the need for program revisions tailored to this population. The choice of vocational training field significantly impacts downgrading, with graduates of technical training programs experiencing advantages. This emphasizes the importance of diversifying training fields and aligning them with market demands.

This study provides valuable insights into the phenomenon of professional downgrading among young vocational training graduates in Morocco. The findings emphasize the need for targeted policy interventions. Recommendations include supporting young graduates, reassessing programs offered by the ANAPEC, and enhancing technical training to better align with the evolving demands of the labor market.

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

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.

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.

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.

The purpose of this paper is to examine the association between company reputation and dividend policy.

In this study, sample of 98,809 firm-year observations from 22 countries covering 2005–2016 were used.

Firm reputation concerns are associated with higher propensities to pay dividends and payout ratios. Further, this positive effect is more pronounced for firms with high free cash flows, high information asymmetry and low institutional monitoring. The results are robust to an instrumental variable approach, propensity score matching and the Heckman two-stage correction approach while addressing endogeneity concerns.

These findings have significant implications for various stakeholders, such as existing and potential investors, managers, policymakers and regulators, by providing insights into the relationship between corporate reputation and firm dividend payout decisions. Corporate reputation is highlighted as crucial for accessing finance, emphasizing the role of national regulators and policymakers in facilitating firms' efforts to improve their reputation. The study highlights the dynamics of corporate reputation and dividend payout, calling for proactive engagement from regulators and policymakers. Crafting policies conducive to reputation-building can enhance firms' financial prospects, indicating the need for strategic interventions at managerial, regulatory and policy levels. Understanding the influence of economic context is crucial for firms to tailor reputation management strategies and optimize funding opportunities in different economic environments.

Overall, results suggest that reputation serves as a disciplining mechanism, where firms will pay dividends to maintain their reputations.

This paper aims to examine the influence of sustainability reporting on bank performance. Furthermore, this study investigates the impact of the country’s economic development, financial system and crisis in moderating sustainability reporting and bank performance relationship.

The sample consists of 400 listed banks from 19 countries over the 2009–2022 period. Panel fixed-effect regression is applied, and System Generalized Method of Moments is used as robustness to address endogeneity concerns. The results are robust and survive several sensitivity tests.

The results, aligning with legitimacy and agency theories, suggest a negative relationship between sustainability reporting and bank performance. Based on further classifications, results suggest the negative (positive) impact of country’s financial system (economic development) in moderating the sustainability reporting and bank performance nexus. Finally, this study documents the positive influence of sustainability reporting on bank performance during the crisis period. Overall, the findings fail to support the reduced information asymmetry accruing from higher sustainability disclosures in developing and bank-based economies.

This study has important implications for regulators, policymakers and other stakeholders, especially in light of recent banking scandals that have deteriorated stakeholders' faith in financial institutions' reporting quality.

This study extends the scant literature on sustainability reporting in banking from a cost-benefit vantage point. Furthermore, to the best of the author’s knowledge, no previous research has examined the moderating role of the country’s financial structure and crisis in sustainability reporting and bank performance relationship.

This paper proposes a framework to identify a pattern in the relationship between firms’ cost structure (i.e. fixed versus variable) and their volatility in stock returns.

Our empirical analysis is based on a panel data regression where we use an extended sample period and a time-series regression-based elasticity measure of operating leverage.

We document significantly higher systematic risk among firms with large fixed costs, a conclusion which confirms theoretical predictions of earlier studies. In new findings, we document high firm-specific risk and high stock return volatility among firms with a fixed cost structure.

The paper fills a gap in the literature by examining the effect of cost structure using various operating leverage measures and other control measures for firm characteristics on idiosyncratic risk. Studies that seek to explain firms’ systematic risks are numerous; conversely, there are relatively fewer studies on the determinants of firms’ specific risks.

The paper aims at studying the effect of management practices on the extensive and intensive export margins of Egyptian manufacturing firms.

The study relies on the 2020/2021 Egyptian Industrial Firm Behavior Survey (EIFBS) which comprises 2,383 manufacturing firms representing small, medium, and large sized firms located in different regions of Egypt: Urban Governorates, Lower Egypt, and Upper Egypt. It constructs an overall management z score for each firm to estimate its effect on a firm’s probability of exporting and value of exports using Ordinary Least Squares (OLS) regressions.

Results indicate that good management is associated with a higher probability of firm exporting as well as higher export revenues conditional on exporting, robust to controlling for the level of domestic sales. These effects do not differ by firm ownership or type of sector, but rather by firm size, with managerial competence raising the probability of exporting more for large-sized firms. Additionally, good management is associated with higher firm productivity, innovation and worker training propensities which gives evidence that it is both an efficiency and a quality enhancer. Moreover, monitoring and targeting practices have significant positive effects on both margins, while incentives are only significant for the extensive margin.

Firms that aim at enhancing their export prospects and revenues should devote resources to review and upgrade their management systems to boost their product quality and production efficiency. Policy-wise, the government should create a competitive market environment that is open to both domestic and foreign firms’ entry to stimulate the adoption of better management practices.

The paper is the first to explore the link between firm management practices and export outcomes for a MENA country (Egypt). It makes use of a recent survey, the 2020/2021 Egyptian Industrial Firm Behavior Survey (EIFBS). The findings shed light on the importance of different management components (monitoring, targeting and incentives) in driving a manufacturing firm’s export performance.

Countries globally have implemented policies or regulations promoting greater gender diversity in boardrooms. We investigate whether gender diversity on corporate boards leads to higher Sustainable Development Goals (SDG) commitment through these disclosures.

Using 16,659 firm-year observations across 42 countries for the years 2019 and 2020, we use disclosure data from the Refinitiv database to measure the sample firms’ stated commitment to sustainable development.

Our data provide useful comparative information on the countries, legal jurisdictions and types of SGDs currently being disclosed. Our analyses reveal that gender diverse boards are associated with greater levels of SDG disclosures, with such commitment being more significant when there is more than one woman on the board. We also find that women board members are associated most with the PEOPLE and PLANET groups within the SDGs, and our results are robust to additional analyses and endogeneity concerns.

Although gender diversity has been examined within a corporate social responsibility and ethical, social and governance lens, this examination needs to be extended to the SDGs, given the latter’s multi-year horizon and involvement from governments, the private sector and a very broad cross-section of the global community. Our results reinforce global calls for increasing gender representation at the highest levels of organisations to meet the expectations of a greater range of stakeholders in terms of SDG commitment.
