- Driving tourism development: multicriteria decision-making in Rio de Janeiro’s tourism sectorPublication . Ferreira, Fernanda A.; Coutinho, José Augusto da Fonseca Pinto; Gomes, Carlos Francisco Simões; Santos, Marcos dosAs operations stabilized after the onset of the Covid-19 pandemic, many economic sectors have gradually resumed activities, with some nearing pre-pandemic levels. Tourism is no exception, as it continues to be used as a source of resource acquisition and socioeconomic development. The purpose of this study is to promote the development of the tourism sector in the municipality of Rio de Janeiro by applying the Analytic Hierarchy Process (AHP) and AHP-Gaussian (AHP-G) multicriteria analysis methods to support potential public and/or private investments in tourism. The findings of this study will help a travel agency make a strategic decision about where to open a new branch, taking into account the sector’s potential in Rio de Janeiro. The study found that São Conrado and Ipanema are ideal neighbourhoods for establishing a new travel agency branch. Furthermore, the methodology used in this study can be used as a guideline for other organizations in the field looking to undertake similar evaluations, providing a structured approach to decision-making and investment evaluation.
- Sequential move model for quantity and quality competition in the restaurant industryPublication . Ferreira, Flávio; Koerich, GuilhermeThis paper examines a competition in both quality and quantity between two asymmetric restaurants. The model that we consider is a Stackelberg duopoly on quantities (sequential decision-making), after a simultaneous choice of quality. Our findings indicate that the restaurant with the best reputation provides a greater variety of higher-quality food compared to its competitor. We also examine how variations in restaurants’ reputations impact market equilibrium outcomes. We demonstrate that an increase in the reputation gap between restaurants boosts the profits of both estab lishments, enhances consumer surplus, and improves social welfare. Additionally, in comparison to the scenario under the Cournot model (simultaneous decision making), small restaurant’s profits are lower under Stackelberg model, while the opposite holds for the large restaurant’s profits and for social welfare.
