Market configurations when marginal costs are quality-dependent
Pires, Cesaltina Pacheco; Jorge, Sílvia Ferreira; Catalão-Lopes, Margarida; Pinho, Joana; Garcês, Pedro; Alventosa, AdrianaMost quality-then-price decision models under vertical product differentiation consider a predetermined market configuration. We endogenize market configuration considering quality-dependent marginal costs and conclude that a strictly interior full coverage duopoly holds for some parameter values, unveiling the relevance of this commonly assumed market structure. Moreover, we show that a monopoly never arises i...
Market configurations when marginal costs are quality‐dependent

We endogenize market configuration considering quality-dependent marginal costs and conclude that a strictly interior full coverage duopoly holds for some parameter values, unveiling the relevance of this commonly assumed market structure.

Vertical product differentiation in the lab: impact of consumers’ preferences
Alventosa, Adriana; Pinho, Joana; Jorge, Sílvia Ferreira; Catalão-Lopes, MargaridaWe revisit a quality-then-pricing duopoly game, theoretically and experimentally exploring how heterogeneity in consumers’ preferences affects firms’ decisions and profits. We find that firms differentiate less their products in the lab than the theoretical model predicts, especially when the heterogeneity in consumers’ preferences is high. When this heterogeneity is small, the firm producing the low-quality go...
How does firms’ cost structure affect their quality–price mix? An experimental ...
Alventosa, Adriana; Pires, Cesaltina Pacheco; Jorge, Sílvia Ferreira; Pinho, Joana; Catalão-Lopes, MargaridaExperimental literature on product differentiation is scarce and mostly focused on horizontal product differentiation. This paper focuses on vertical product differentiation considering a quality-then-pricing duopoly game and exploring how firms’ cost structure affects firms’ decisions and market structure. Two scenarios are considered, differing in the way quality affects production costs: in the first, qualit...
Public–private collusion
Mota, Filipa; Correia-da-Silva, João; Pinho, JoanaWe study collusion between a public firm and a private firm facing linear demand and quadratic costs. We characterize the collusive outcome that results from Nash bargaining and compare it to the non-cooperative outcome. If the public firm’s taste for consumer surplus is mild, both firms reduce output (as in a private duopoly). If it is intermediate, while the public firm reduces output, the private firm expand...
Patterns of Medication Management and Associated Medical and Clinical Features ...
Dixe, Maria dos Anjos; Pinho, Joana; Pereira, Filipa; Verloo, Henk; Meyer-Massetti, Carla; Pereira, Sónia GonçalvesAgeing is frequently associated with multimorbidity and polypharmacy. The present study aimed to identify the current medication management patterns and the profiles of homedwelling older adults and to find any association with their conditions, including frailty and cognitive impairment. Within the scope of this cross-sectional study, 112 older adults living in the community were assessed via face-to-face stru...
Application of the dynamic model of assessment and family intervention to conti...
Pinho, Joana; Viseu, Inês; Carvalho, Dayane; Sousa, Sara; Figueiredo, Maria Henriqueta; Vilar, AnaBackground: The Dynamic Model Assessment and Family Intervention (MDAIF) refers to the relationship between family members that evolve in a reciprocal interaction (Figueiredo, 2012). Dynamic and flexible, it allows the mobilization of its components at the different levels of the nurse's performance. Objectives: Identify diagnoses and interventions aimed at the family, in order to obtain health gains for the p...

Pinho, Joana; Viseu, Inês; Carvalho, Dayane; Sousa, Sara; Figueiredo, Maria; Vilar, Ana IsabelEnquadramento:oModelo Dinâmico de Avaliação e Intervenção Familiar (MDAIF) reporta-se à relação entre os elementos da família que evoluem numa interação recíproca (Figueiredo, 2012). Dinâmico e flexível, permite a mobilização dos seus componentes nos diversos níveis de atuação do enfermeiro. Objetivos:identificar diagnósticos e intervenções dirigidas à família, no sentido de obter ganhos em saúde para a pessoa,...
How do antitrust regimes impact on cartel formation and managers’ labor market?...
Fonseca, Miguel A.; Gonçalves, Ricardo; Pinho, Joana; Tabacco, Giovanni A.We explore the impacts of different antitrust regimes on managers’ labor contracts, when shareholders are intent on their managers engaging in price fixing activities. We compare legal regimes that fine firms to regimes that prosecute managers. We build a theoretical model, which we take to the laboratory. We observe contract choices of shareholders for a given legal regime, as well as the probability of manage...
Aprender português língua de acolhimento, em contexto não formal : imigrantes e...
Pinho, Joana; Ançã, Maria HelenaA deslocação, a nível mundial, de pessoas de forma forçada, tem potenciado a chegada de um número significativo de imigrantes e refugiados à Europa. Neste panorama, é desafio da Educação em Portugal dar respostas de acolhimento que incluam indubitavelmente o ensino da Língua Portuguesa, enquanto língua de acolhimento. Este estudo, de natureza qualitativa e que privilegia a estratégia de estudo de multicaso, vis...
