Stadiums and Scheduling: Measuring Deadweight Losses in the Victorian Football League, 1920–70

Over a 50 year period, Australian Rules football's major league, the Victorian Football League, did not always use its largest and best-equipped stadium for regular season games between its most popular teams or schedule those teams to play twice in a regular season. We calculate deadweight losses from the use of capital goods (stadiums) and effects of match scheduling in this professional sports league. Such analysis has not been attempted previously because of the absence of a counterfactual. The welfare losses were significant but not sufficient to threaten the survival of a distance-protected cartel.     

Public–private partnerships for nature-based tourist attractions: the failure of Seal Rocks

In 1998, the Seal Rocks Sea Life Centre opened on Phillip Island, Australia. It was a public–private partnership, with a privately funded tourist attraction built on a government-owned protected area. Almost immediately it was beset by problems and court action found in favour of the private developer, who was awarded $A37 million in damages, with ownership of the centre returning to the state. This article fills a gap in the literature examining public–private partnerships by considering this failed venture. It is a qualitative case study, analysing the 2003 appeal court judgement in the case and newspaper accounts from 1995 to 2004. Our findings highlight that deficiencies with the drafting of commercial contracts for public–private partnerships may limit the environmental and economic benefits that are being sought by governments through these arrangements. In this case, the application of a “best efforts” clause was critical, as it required that priority was given to the commercial success of the project over environmental and planning concerns. Furthermore, the development was a centralised decision made by the state government, affording very little input from local parks management and community stakeholders. Such a court finding has important ramifications for future developments of partnership agreements in nature-based tourism.     

Maximizing an equity portfolio excess growth rate: a new form of smart beta strategy?

It has been claimed that, for dynamic investment strategies, the simple act of rebalancing a portfolio can be a source of additional performance, sometimes referred to as the volatility pumping effect or the diversification bonus because volatility and diversification turn out to be key drivers of the portfolio performance. Stochastic portfolio theory suggests that the portfolio excess growth rate, defined as the difference between the portfolio expected growth rate and the weighted-average expected growth rate of the assets in the portfolio, is an important component of this additional performance (see Fernholz [Stochastic Portfolio Theory, 2002 (Springer)]). In this context, one might wonder whether maximizing a portfolio excess growth rate would lead to an improvement in the portfolio performance or risk-adjusted performance. This paper provides a thorough empirical analysis of the maximization of an equity portfolio excess growth rate in a portfolio construction context for individual stocks. In out-of-sample empirical tests conducted on individual stocks from 4 different regions (US, UK, Eurozone and Japan), we find that portfolios that maximize the excess growth rate are characterized by a strong negative exposure to the low volatility factor and a higher than 1 exposure to the market factor, implying that such portfolios are attractive alternatives to competing smart portfolios in markets where the low volatility anomaly does not hold (e.g. in the UK, or in rising interest rate scenarios) or in bull market environments.

Cost-effectiveness of subdermal implantable buprenorphine versus sublingual buprenorphine to treat opioid use disorder

Aims: Subdermal implantable buprenorphine (BSI) was recently approved to treat opioid use disorder (OUD) in clinically-stable adults. In the pivotal clinical trial, BSI was associated with a higher proportion of completely-abstinent patients (85.7% vs 71.9%; p?=?.03) vs sublingual buprenorphine (SL-BPN). Elsewhere, relapse to illicit drug use is associated with diminished treatment outcomes and increased costs. This study evaluated the cost-effectiveness of BSI vs SL-BPN from a US societal perspective.

Methods: A Markov model simulated BSI and SL-BPN cohorts (clinically-stable adults) transiting through four mutually-exclusive health states for 12 months. Cohorts accumulated direct medical costs from drug acquisition/administration; treatment-diversion/abuse; newly-acquired hepatitis-C; emergency room, hospital, and rehabilitation services; and pediatric poisonings. Non-medical costs of criminality, lost wages/work-productivity, and out-of-pocket expenses were also included. Transition probabilities to a relapsed state were derived from the aforementioned trial. Other transition probabilities, costs, and health-state utilities were derived from observational studies and adjusted for trial characteristics. Outcomes included incremental cost per quality-adjusted-life-year (QALY) gained and incremental net-monetary-benefit (INMB). Uncertainty was assessed by univariate and probabilistic sensitivity analysis (PSA).

Results: BSI was associated with lower total costs (?$4,386), more QALYs (+0.031), and favorable INMB at all willingness-to-pay (WTP) thresholds considered. Higher drug acquisition costs for BSI (+$6,492) were outpaced, primarily by reductions in emergency room/hospital utilization (?$8,040) and criminality (?$1,212). BSI was cost-effective in 89% of PSA model replicates, and had a significantly higher NMB at $50,000/QALY ($20,783 vs $15,007; p?Conclusions: BSI was preferred over SL-BPN from a health-economic perspective for treatment of OUD in clinically-stable adults. These findings should be interpreted carefully, due to some relationships having been modeled from inputs derived from multiple sources, and would benefit from comparison with outcomes from studies that employ administrative claims data or a naturalistic comparative design.     

Sustainable travel writing? Exploring the ethical dilemmas of twenty-first-century travel writers

There is a paucity of academic literature on travel writing that examines travel writers and their perceived influence on sustainability. This article addresses this lacuna by exploring how travel writers understand their responsibilities and reflects on ethics in their profession, particularly in how foreign destinations and cultures are portrayed. This is significant because some travel writers have been accused of contributing to what interviewees called the “Lonely Planet Syndrome”, the notion that writing about a place will introduce and encourage mass tourism, changing the original state of the place for the worse. In this qualitative, phenomenological study, data were collected from 23 in-depth interviews with twenty-first-century travel writers and analysed using an Interpretive Phenomenological Analysis. Findings suggest that while some interviewees expressed anxiety about their perceived accountability to mediate foreign cultures responsibly, others embraced their role as a cultural mediator. They cared about local cultures and wanted to write in responsible ways by supporting more sustainable outcomes, reflected in the themes of cross-cultural understanding, socio-cultural and environmental advocacy and promoting benefits of tourism to communities. Future studies could include exploring the role of travel editors, travel writers’ professional knowledge and the growing role of travel blogs.     

The Effect of Employment while in High School on Educational Attainment: A Conditional Difference‐in‐Differences Approach*

Using American panel data from the National Education Longitudinal Study of 1988, this article investigates the effect of working during grade 12 on attainment. We employ, for the first time in the related literature, a semiparametric propensity score matching approach combined with difference‐in‐differences. We address selection on both observables and unobservables associated with part‐time work decisions, without the need for instrumental variable. Once such factors are controlled for, little to no effects on reading and math scores are found. Overall, our results therefore suggest a negligible academic cost from part‐time working by the end of high school.
