Optimal pricing and capacity management in service systems with delay-sensitive mixed-risk customers
No full textIn service systems with delay-sensitive customers, customer decisions to join the queue or balk influence demand, impacting service provider profits. Studies show that customers can be risk-seeking for short waits and risk-averse when waits exceed expectations. Prior research on this mixed-risk attitude is limited, focussing on optimal pricing policies from a social welfare perspective. This study fills this gap by investigating the impact of this behaviour on customer joining strategies and the provider's pricing and capacity policies. We analyse a profit-maximising firm managing an unobservable queue where customers display mixed-risk behaviour towards delay parameterised by a risk-switching point and a degree of risk propensity. Customers join or balk based on expected utility, while the firm determines the service price and rate to maximise expected profit. We derive optimal strategies for both customers and the firm under scenarios with concave or convex capacity costs. Computational experiments show that optimal pricing, capacity, and profit peak at intermediate risk-switching points. For smaller points, optimal price and capacity rise with the customers' degree of risk propensity, while larger points have minimal impact. Numerical exploration emphasises the significance of capacity cost and the effectiveness of leveraging price over controlling capacity for maximising firm profitability

No full textParty system types and the decline of systemness in Western Europe: are party system classifications still useful?
No full textParty system classifications have been central in political science, especially until Sartori's influential typology in 1976. However, recent years have seen diminished attention to such classifications. Western European party systems have significantly transformed, particularly over the last 15 years due to multiple crises, affecting their core structure, or what Sartori termed ‘patterns of interparty competition.’ This raises questions about whether these changes have undermined the very concept of systemness, making classifications irrelevant. This research note redefines party systems based on the number and composition of relevant political poles (governing alternatives) and, through a long-term analysis of Western Europe (20 countries since 1945), assesses their degree of systemness. Results indicate that many systems have become ‘non-systems,’ with fluctuating and unstable party poles. Most Western European systems have exhibited this ‘non-system’ type for at least half of legislatures since 1989, thus making classifications only short-lived snapshots and inevitably useless for long-term accounts
For better or for worse. The dissolution of interethnic marriages in Italy
No full textI study the role of endogamy, or marrying within the same cultural-ethnic group, on marital instability. Using Italian administrative data on the universe of marriages and separations, I show that interethnic marriages exhibit a 15 percent higher risk of separation than homogamous marriages of natives. Moreover, interethnic marriages between native women and immigrant men are 6.4 percentage points more at risk than marriages between native men and immigrant women. Gender differences map onto cultural differences. Intermarriages of immigrants with marked cultural divides are significantly more at risk, and different measures of cultural distance are informative about the incidence of separation
Responsible leadership: fostering employee engagement through positive emotional climate
No full textPurposeEmployee engagement is crucial for organizational success, yet it has become increasingly challenging, particularly post-COVID-19. Research highlights that engaged employees contribute significantly to organizational performance, driving productivity, creativity and commitment. This paper aims to explore the role of emotional climate and responsible leadership in fostering engagement.Design/methodology/approachData were collected from 100 employees across various organizations using an online survey. Participants completed questions on demographic, work-related factors and measures of responsible leadership, emotional climate and employees' engagement. Multiple regression analyses tested the relationships between responsible leadership, emotional climate and engagement, while mediation analysis explored the three-way relationship across variables.FindingsThis study demonstrates a significant positive relationship between responsible leadership and employees' engagement. Responsible leadership, characterized by ethical behavior, transparency and stakeholder focus, fosters employee engagement. Additionally, the study highlights responsible leadership's role in enhancing organizational emotional climate, with dimensions like moral person and moral manager driving this effect. Such leadership promotes fairness and ethical standards, cultivating a positive climate. The findings show that emotional climate directly impacts engagement, for example, encouraging risk-taking, creativity and deeper involvement. Finally, emotional climate was found to mediate the relationship between responsible leadership and engagement, emphasizing the importance of ethical and socially sustainable practices in modern organizations.Originality/valueBy investigating the dynamic interplay between responsible leadership and emotional climate, this study seeks to advance understanding of how their combined influence shapes employee engagement and organizational performance, thereby addressing a notable gap in the existing literature
