title: Building bridges: Treating a new transport link as a real option

authors: Grimes, Arthur

subjects: transport investment

abstract: A transportation investment that materially improves links between centres opens up previously unavailable options for new activities. Traditional cost-benefit analysis does not adequately take account of the value of this option; real options theory must be added to the analysis to evaluate the full benefits. This paper uses a specific example, Auckland’s Harbour Bridge, to motivate the importance of real options analysis. Using illustrative, multi-period models of the real options problem, it highlights how inclusion of real options factors may either increase or decrease the attractiveness of a proposed investment. The models identify situations in which it is optimal to invest even where a standard benefit-cost ratio is less than one.

title: How much would US union membership increase under a policy of non-exclusive representation?

authors: Harcourt, Mark

subjects: industrial relations

abstract: Purpose – In light of the low-union density and a huge representation gap in the US representation system. The purpose of this paper is to examine the effectiveness of the system under majority rule and to provide some empirical evidence on how much union membership would increase in the USA if a policy of non-exclusive representation, as adopted in New Zealand, are to be implemented. 

Design/methodology/approach – The sample for the study consists of 227 New Zealand organizations, employing over 180,000 workers. Logistic regression is used for the analysis with the dichotomous dependent variable indicating whether there is majority union support. 

Findings – If the USA allowed and supported minority unionism, union membership could increase by 30 percent or more. Workers in smaller, private-sector organizations outside healthcare, education, and manufacturing are most disadvantaged by the majority-rule system. 

Practical implications – Given that many workers' needs for representation have not been addressed by the current US majority rule system, consideration of minority representation to enhance representation effectiveness and understanding its implications are of critical importance, especially for a democratic society. 

Originality/value – The paper offers empirical data on the implications of a change of the US representation system and proposes three options for incorporating minority representation.

title: Racial inequalities in engineering employment in Aotearoa New Zealand

authors: Roy, Rituparna

abstract: This report presents findings from research on racism and inequality in engineering employment in New Zealand. Conducted as part of the Working to End Racial Oppression (WERO) research programme (see: https://wero.ac.nz/), this study examines how racial discrimination operates in recruitment and career progression within the engineering sector. The research was carried out with the support of Engineering New Zealand | Te Ao Rangahau and the Association of Consulting and Engineering New Zealand. 

This research involves two phases of in-depth interviews. The first phase entails interviews with industry key informants such as human resources staff, managers, or people from diversity and culture teams for different engineering firms that ranged from very small to large in size. In the second phase, currently employed engineers from different ethnic groups were undertaken, including Māori, Pacific, Pākehā, Asian and Middle Eastern, Latin American and African (MELAA). The findings from these two sets of interviews are presented respectively in Section 3 and 4. 

The research also included an analysis of the workforce composition and wage gaps in Engineering based on analysis of Census and New Zealand Income Survey data. This analysis, which is presented in Section 1, revealed the disproportionately low number of female engineers, and of Māori and Pacific people employed as engineers. Analysis of average median hourly wages revealed notable differences, with Māori and Pacific engineers having median wages that are around 80% of the overall median. 

There has been a significant emphasis on Diversity, Equity and Inclusion (DEI) in recruitment and human resource management in Engineering in recent years. This emphasis reflects industry efforts to address known ethnic and gender imbalances in the workforce. Industry informants, however, highlighted several challenges, tensions, and contradictions they faced in integrating and practicing DEI in recruitment. Employers often struggle to balance competing frameworks such as equity, meritocracy, and people-focused approaches, making recruitment decisions complex. Despite initiatives like blind CV screening, targeted graduate programmes and preferential shortlisting of Māori and Pacific applicants, the industry remains heavily merit-driven. Additionally, DEI efforts are largely gender-focused, lacking an intersectional approach that considers overlapping social inequities. 

The interviews with engineers revealed that individuals from different ethnic groups face distinct barriers and challenges in securing employment and advancing their careers. For Māori and Pacific engineers, the pathway into engineering is severely limited, with only a small number entering the profession each year. Those currently employed often experience what has been described V as a ‘cultural tax’—being expected to take on cultural responsibilities in addition to their technical roles, without monetary compensation or clear career advancement opportunities. Racialised immigrant engineers, on the contrary, reported devaluation and deskilling of their qualifications and experience based on their ethnic and national origins. Despite extensive work experience in their home countries, they were often required to restart their careers in graduate or entry-level positions. Several participants shared experiences of unfair promotions, where White, European, and Anglophone employees were favoured for leadership roles. When discussing their own career trajectories, most non-Pākehā and nonEuropean participants expressed scepticism about ever being promoted to senior positions with decision-making authority. 

The accounts of discriminations and racial inequalities shared by engineers have profound implications for their employment, career progression, well-being, and society at large. Navigating a predominantly monocultural work environment—marked by challenges like cultural taxation, glass ceilings, and the ‘white boys’ club’—places additional burdens on racialised groups. The pressure to constantly prove their worth further exacerbates these issues, leading to serious retention problems. If not addressed, the sector risks losing engineers from diverse ethnic backgrounds, exacerbating gender and ethnic pay gaps, worsening representation and diversity issues, and reinforcing systemic racial inequities. 

Addressing monoculturalism and the ‘white boys’ club’ culture and fostering a genuinely inclusive profession will require systemic changes within engineering firms and in accepted norms in the profession and industry. Without a shift in workplace culture, efforts to recruit more engineers from underrepresented backgrounds will remain ineffective, as many will continue to leave due to unwelcoming environments. To create lasting change, DEI initiatives must go beyond recruitment and actively reshape the structures, policies, and day-today practices that define the industry. This requires the mindful integration of diverse cultural values and practices into every layer of organisational functions, including recruitment, career advancement frameworks, and job descriptions.
