Negative Film Plot and Tourists´ Image and Intentions: The Case of City of God

This study aims to contribute to the understanding of the effects of films with a negative plot on tourists’ cognitive and affective image about Brazil and behavioral intentions of visiting the country. The film selected is City of God, one of the most internationally acclaimed motion pictures produced in Brazil. The results suggest that films with a negative plot tend to negatively reinforce the viewers’ evaluations of the image attributes, although the influence on the general image tends to be subtle. Moreover, it was concluded that in the case of films with a negative plot, the imagery of landscapes is the element that is most likely to increase visiting intention.     

Effectiveness of interventions to prevent motorcycle injuries: systematic review of the literature

Globally, 49% of deaths from traffic crashes occur among vulnerable road users, including pedestrians, bicyclists, and motorcyclists. Approximately, a quarter of those killed are motorcyclists. The authors carried out a systematic review of the literature to evaluate the effectiveness of interventions to prevent motorcycle crashes and the associated morbidity and mortality. The studies included in this review provide evidence for the effectiveness of helmet use, protective clothing, training, and penalties for alcohol consumption and speeding in preventing injury and death to motorcyclists. The use of helmets is effective, especially if it is universally required by law for drivers and passengers. Training to obtain a license also has positive effects but not when it is totally voluntary. There is limited but consistent evidence that strengthening laws for penalties related to alcohol consumption or speeding has an impact on risk. Traffic calming interventions could help reduce crashes in urban areas. In jurisdictions where there is limited regulation or adherence to effective measures, such as the use of helmets, efforts should be directed primarily at expanding such practices. In other areas, efforts can focus on approaches based on alternative effective measures or on more innovative interventions adapted to local conditions.     

Brand Personality of Global Quick-Service Restaurants in Emerging and Developed Markets: A Comparative Study in Brazil and the U.S.

This study aimed to determine the dimensions of the personality of global quick-service restaurant brands perceived by young consumers in the U.S. and Brazil, and whether these dimensions showed similar configurations in both countries. A survey was carried out with two QSR brands (McDonald's and Subway). Data analysis utilized exploratory and confirmatory factor analysis. The study identified five personality dimensions for each of the brands studied in each country. Results support the proposition that global brands can carry a common meaning across nations, but also that certain local nuances of brand personalities can differ.     

Price dispersion, information and learning

We consider an economy where trade is decentralized and agents have incomplete information with respect to the value of money. Agents’ learning evolves from private experiences and we explore how the formation of prices interacts with learning. We show that multiple equilibria arise, and equilibria with price dispersion entail more learning than equilibria with one price. Price dispersion increases communication about private histories, which in turn increases the overall amount of information in the economy. We also compare ex ante welfare under price dispersion and one price. Our results show that, despite the existence of some meetings where no trade takes place, ex ante welfare under price dispersion may be higher than under one price.     

The Multiple Boundaries of the Firm*

ABSTRACT The notion of firm boundaries has received considerable attention in theories of the firm that address the problems of investment incentives and mitigation of hold‐up problems. In this paper we attempt to develop a different approach to the problem of vertical firm boundaries, based on recent advances in the capabilities view of the firm. Our arguments rely on the pioneering insights of Penrose, Richardson and Loasby to elaborate a view of the boundaries determined by the interaction of the firm's direct and indirect capabilities with other actors. We develop the notion of indirect capabilities to highlight how firm boundaries respond to the distribution of capabilities in the economy as well as the modes of access to complementary and external capabilities. We conclude that the evolution of firm boundaries must be understood in the context of decisions on how the firm relates to other actors in its environment.     

The HIV Epidemic,Skill Heterogeneity,and Output

This paper investigates the effect of HIV/AIDS on output using an overlapping generations model with heterogeneous agents calibrated to sub‐Saharan Africa. Output is found to be below a no‐AIDS output in a range between 3% (10%), when only unskilled workers are affected, and 10% (28%), when only skilled workers are affected, whenever the overall infection rate is 7% (20%). When investigating the hypothesis that AIDS affects skilled workers more severely than unskilled at the beginning of the epidemic, with the effect switching as the epidemic becomes more mature, the findings are that the economy can be 8% smaller along the transition path. In all scenarios where the epidemic is temporary, it would take four to five generations or about 90 years for sub‐Saharan Africa to recover.     

A health economic model to assess the cost-effectiveness of OPTIFAST for the treatment of obesity in the United States

Objectives: Obesity is associated with high direct medical costs and indirect costs resulting from productivity loss. The high prevalence of obesity generates a justified need to identify cost-effective weight loss approaches from a payer’s perspective. Within the variety of weight management techniques, OPTIFAST is a clinically recognized and scientifically proven total meal replacement Low Calorie Diet that provides meaningful results in terms of weight loss and reduction in comorbidities. The objective of this study is assess potential cost-savings of the OPTIFAST program in the US, as compared to “no intervention” and pharmacotherapy.

Methods: An event-driven decision analytic model was used to estimate payer’s cost-savings from reimbursement of the 1-year OPTIFAST program over 3 years in the US. The analysis was performed for the broad population of obese persons (BMI >30?kg/m²) undergoing the OPTIFAST program vs liraglutide 3?mg, naltrexone/bupropion and vs “no intervention”. The model included the risk of complications related to increased BMI. Data sources included published literature, clinical trials, official US price/tariff lists, and national population statistics. The primary perspective was that of a US payer; costs were provided in 2016?US dollars.

Results: OPTIFAST leads over a period of 3 years to cost-savings of USD 9,285 per class I and II obese patient (BMI 30–39.9?kg/m²) as compared to liraglutide and USD 685 as compared to naltrexone/bupropion. In the same time perspective, the OPTIFAST program leads to a reduction of cost of obesity complications of USD 1,951 as compared to “no intervention”, with the incremental cost-effectiveness ratio of USD 6,475 per QALY. Scenario analyses also show substantial cost-savings in patients with class III obesity (BMI?≥?40.0?kg/m²) and patients with obesity (BMI?=?30–39.9?kg/m²) and type 2 diabetes vs all three previous comparators and bariatric surgery.

Conclusions: Reimbursing OPTIFAST leads to meaningful cost-savings for US payers as compared with “no intervention” and liraglutide and naltrexone/bupropion in obese patients. Similar results can be expected in matching healthcare settings of other countries. Moreover, OPTIFAST has additional clinical and economic advantages through very low complication and adverse events rates.     

Services, products, and the institutional structure of production

This paper revisits the product-service distinction from an institutional perspective. Much of the literature in marketing and management has focused on the intrinsic characteristics of services with a view to derive implications for the management of service-based firms. Our key argument is that the quest for foundational differences between products and services is misguided. What counts as a product or a service is dependent on the nature of producer-user interactions and the institutional structure of production rather than on any essentialist feature of products or services. Furthermore, we develop the argument that services play an increasingly important role in manufacturing firms and we explore the reasons that underpin this trend.
