This study investigates the impact of the increasing proportion of older workers in the workforce by establishing a theoretical framework and estimating the degree of substitutability between them and their younger counterparts.

The first step is to establish a theoretical framework that combines older and younger workers with imperfect substitutability in the production of final goods within an aggregate production function. The author then derives an equation that relates the relative wage, relative supply and elasticity of substitution between the worker types, for use in estimation. Using data from Japan’s Basic Survey on Wage Structure and Population Census from 2010 to 2019 across 47 prefectures, the author estimates the elasticity of substitution between older and younger workers in Japan.

The author finds that workers aged 55 and over and their younger counterparts are gross substitutes, and the estimated elasticity of substitution is in the range of 2.33–2.86. This implies that a 10% increase in the relative number of workers aged 55 and older leads to a fall in their relative wage in the range of 3.5–4.3%. The study estimations suggest that since 2010, there has been a convergence in the relative wage of older workers across Japan’s prefectures.

Understanding the degree of substitutability between older and younger workers is essential for quantitatively assessing the impact of workforce aging, technological advancements and labor policies on the wage distribution. This study estimates the elasticity of substitution between the two worker types based on a theoretical model, and utilizes recent datasets and methodology not adequately addressed in previous literature.

This paper aims to test penis panic theory, which predicts that trans women will face more discrimination than trans men in some but not all situations.

Respondents were 262 American college students who were all enrolled in the same undergraduate course. They were presented with a case about coworker resistance to transgender employees' use of the workplace restrooms of their choice. Four versions of a case were randomly distributed as follows: trans woman, restroom with one toilet; trans woman, restroom with three toilets; trans man, restroom with one toilet and trans man, restroom with three toilets.

The authors observed greater discrimination against trans women compared to trans men when there was one toilet but not when there were three toilets. This supports penis panic theory.

The chief limitation was the use of American college students as respondents. The results may not generalize to practicing managers especially in other countries. Future researchers should develop a scale to measure situational discrimination against trans women. This study should be replicated in other contexts to deepen the understanding of discrimination against trans men and trans women with disabilities, as well as discrimination against nonbinary individuals who identify as neither trans men nor trans women.

Employers need to search for situations in which trans women face greater discrimination than trans men, because they can be resolved in ways that protect the rights of transgender employees no matter how transphobic their coworkers may be. Also, employers need a nuanced approach to combat discrimination that recognizes the unique perspectives of trans men, trans women and other members of the transgender community.

This is the first quantitative study of penis panic theory, and it illuminates the understanding of discrimination against transgender individuals.

This paper aims to examine the effects of political connections (PCs) on corporate financial performance (CFP) in an emerging economy. It also investigates the moderating influence of the directors’ financial expertise (DFE) on the relationship between politically connected firms and their financial performance.

The study sample includes 304 firm-year observations from non-financial Tunisian listed firms covered over 2012–2019. Financial data are from various sources: financial statements, annual reports, official bulletins of the Tunisian Stock Exchange (TSE) and the Financial Market Council. PCs and DFE data are manually collected from the TSE and companies’ websites. Multivariate regression analyses are used to test the research hypotheses.

The results show that PCs negatively affect CFP and the DFE is a moderator variable that exacerbates this negative relationship. These results could be explained on the one hand by the fact that politicians often lack management, professionalism and know-how. On the other hand, political members on boards focus mainly on their political agendas and prioritize their interests rather than firm performance. Furthermore, board directors are more inclined towards the grabbing-hand approach to create personal linkages with these politicians and take personal benefits rather than protect the interests of minority shareholders and effectively use firm resources.

The most important limitation of the study is the small number of non-financial TSE-listed firms. Indeed, the small sample size prevents us from considering industry specificities and working in a homogeneous environment.

This study recommends that external investors pay particular attention to politically connected firms as PCs tend to weaken corporate governance. Also, it helps policymakers better assess the need to harmonize and develop corporate governance standards and practices that account for the specific conditions in Tunisia to mitigate the lobbying of political parties and supervise their abuse of power. Furthermore, the negative relationship between PCs and CFP in a poorly regulated and governed country could be used by financial institutions in their credit scoring.

The findings suggest that the nexus between politics and business draws attention to corruption post-revolution.

The originality and the relevance of this study consist in studying the moderating effect of the DFE on the association between PCs and CFP. To the best of the author’s knowledge, this study pioneers assessing the role of the DFE as a moderating variable. It also supplements prior literature by examining the combined factors, such as PCs and DFE, on CFP in an emerging market.

This chapter presents an investigation into the theory of labour market segmentation and income inequality in the Ghanaian mining sector. Mining activity especially gold mining has been a significant component of exports as well as employment and income earning in the three major mining regions of Ghana. While income growth is an economic benefit, the high incomes associated with the mining sector may lead to greater income inequality. This chapter provides an analysis of mining activity and income inequality in the Western, Eastern, and Ashanti regions of Ghana. The application of labour market segmentation and the Gini coefficient (a measure of inequality) for personal income are found to be significantly associated with the type and levels of mining employment. However, this observation is not linear as income inequality initially increases with mining activity before decreasing at medium to high levels of mining employment, thus following a Kuznets curve pattern. Segregating datasets for indigenous and expatriate staff reveals very different patterns of income inequality. It poignantly increases with indigenous and/or local community personnel relative to expatriate technical personnel at high levels of mining employment; income inequality is lower among the local community residents relative to nationals from other regions and/or from neighbouring countries. This means segmented labour markets (SLM) within the mining industry are likely to be a problem as they result in increased income inequality among locales relative to foreign expatriates.

This paper examines the relationship between poison pills, real earnings management and initial public offering (IPO) failure.

The authors sampled 2,997 IPO firms that went public during 1993-2015.

The authors find that IPO firms manipulate earnings upward using real earnings management. The authors also find that IPO firms exhibiting a higher level of real earnings management have a higher probability of IPO failure. In addition, the authors find that weak shareholders' governance is positively associated with IPO failure.

These results suggest that poor governance structures in failed firms open the door to manipulating real activities and increasing operational risk.

The study findings are of most significant interest to potential investors and other stakeholders affiliated with a firm going public, an auditor, an underwriter, the lawyers who consult with the firm and employees or executives who might consider joining that firm.
