The airline industry faces persistent profitability pressure stemming from high fixed costs, intense competition, and macroeconomic volatility. Since the entry of low-cost carriers (LCCs), ancillary revenue—defined as income generated from services and products supplementary to the core ticket—has evolved from a peripheral activity into a strategic financial pillar for both full-service and low-cost airlines. This study investigates the determinants of passenger willingness to pay (WTP) for à la carte ancillary services and identifies behavioural and demographic profiles that predict purchase frequency. Using a survey of 254 air travellers and a multi-method statistical approach (Chi-square tests, Mann–Whitney U tests, and Kruskal–Wallis with Bonferroni-corrected pairwise comparisons), six hypotheses are tested. The results demonstrate that (i) passengers familiar with à la carte services allocate significantly larger travel budgets to such services (p < .05); (ii) frequent travellers (>5 flights/year) are significantly more likely to purchase à la carte services (χ² = 8.44, p < .01); (iii) frequent-flyer programme (FFP) members purchase ancillary services at substantially higher rates (χ² = 9.70, p < .01); and (iv) contrary to common managerial intuition, short-haul passengers purchase à la carte services more frequently than long-haul passengers (χ² = 4.51, p < .05). Wi-Fi access is valued across all age cohorts without statistically significant differences. The findings extend the revenue management literature by empirically validating familiarity and loyalty-programme membership as the strongest behavioural predictors of à la carte WTP, and offer actionable guidance for targeted personalisation, segmentation, and dynamic pricing strategies. Implications for machine-learning-driven ancillary recommendation systems are also discussed in light of recent advances in offer management (2022–2025).

This study examines the ethical beliefs of Turkish consumers using a modified version of the Muncy-Vitell Consumer Ethics Scale (CES). Turkey’s ethical climate faces challenges such as copyright violations, environmental pollution, deceptive advertising, unsafe products, bribery, and ethical misconduct in business and politics. Focusing on frequent purchasers, the research assesses consumer ethics in shopping behaviors. While prior studies suggest some Turkish consumers engage in unethical practices, this study reveals a heightened sensitivity toward unethical behavior among respondents. Given Turkey’s status as a Muslim-majority country, the influence of Islamic ethical principles on consumption patterns warrants deeper investigation. The findings contribute to understanding how cultural and religious values shape consumer ethics in emerging markets, offering insights for policymakers and businesses aiming to promote ethical consumption.

Pennsylvania's aging transportation infrastructure has long been a cause for concern, with bridges, highways, and other vital components approaching the end of their serviceable lifespans. The state's infrastructure, one of the nation's oldest, is in dire need of repair and replacement, particularly in the case of bridges, many of which are over 50 years old and in poor condition. However, the financial investment required for this task is substantial, posing challenges within the state's budget constraints. To address this infrastructure crisis, an amendment to Pennsylvania's existing legislation, Act 88, is proposed. This amendment would permit local governments to engage in Public-Private Transportation Partnerships (P3s), leveraging private sector financial resources and expertise. Such local government Transportation P3s have the potential to alleviate the state's infrastructure and financial woes. Currently, Act 88 prohibits municipal governments from participating in these partnerships, hindering the Commonwealth's ability to secure private funding and expertise when public resources are limited. This study aims to address the structural deficiencies in Pennsylvania's transportation infrastructure and its $2.2 billion financial deficit, which hampers repair and improvement efforts. The study employs a descriptive, multi-case analysis to investigate how an amendment to Act 88 could enable local municipalities to engage in P3 transportation projects. These partnerships could provide solutions to budgetary and funding challenges, particularly in the context of locally owned bridge repair and replacement projects. The selected cases are evaluated against various performance criteria, such as value, pricing, budgeting, public accountability, regulatory control, and capacity, offering a comprehensive assessment of the potential benefits of local government participation in P3 transportation projects.

In this paper, we examine the impact of CEO power on auditor choice. We are motivated by the competing financial reporting incentives arising from CEO power. Our empirical finding suggests that powerful CEOs are more likely to hire high-quality auditors as a signal of superior financial reporting quality. We contribute to the literature of auditor switch and extend the research on the links between CEO power and firm behaviors.
