Disposição para pagar uma intervenção para melhorar o controlo da hipertensão em hipertensos não controlados : um estudo-piloto

RESUMO - A valorização económica de intervenções preventivas pode contribuir para melhorar a afetação de recursos em saúde. A hipertensão, primeira causa de morte em Portugal, é um grave problema de saúde Pública e o principal fator de risco para a ocorrência de Acidente Vascular Cerebral (AVC). O presente estudo é um primeiro ensaio para quantificar a disposição para pagar (DPP) da sociedade por uma intervenção de promoção da adesão à terapêutica em hipertensos não controlados. Foi aplicado um questionário presencial a uma amostra de conveniência (n=93), numa perspetiva ex post, sendo o questionário constituído por dois formatos de questões e dois cenários de diferentes reduções de pressão arterial sistólica (cenário 1 corresponde à redução de 10 mmHg e cenário 2 à redução de 20 mmHg). O risco de AVC a 10 anos foi adaptado à idade e ao sexo de cada participante. Relativamente ao cenário 1, a DPP média foi de €25,87 e €33,93, dependendo do formato da questão (resposta aberta ou bidding game, respetivamente). Na questão de resposta aberta, 78,3% dos participantes estavam dispostos para pagar pela intervenção, no bidding game 75,6% dos participantes referiram estar dispostos para pagar pelo menos €10. No cenário 2, a DPP média foi de €26,81 e €34,79, dependendo se o formato da questão era do tipo resposta aberta ou bidding game, respetivamente. Na questão de resposta aberta, 84,3% dos participantes estavam dispostos para pagar pela intervenção, no bidding game 76,1% dos participantes referiram estar dispostos para pagar pelo menos €10. Ao contrário do bidding game, nas questões de resposta aberta verificou-se 25,8% e 24,7% de respostas “não sei”, para o cenário 1 e cenário 2 respetivamente, diretamente relacionada com a baixa escolaridade dos participantes (p=0,004). Também se verificou uma maior tendência para respostas às questões de bidding game com valores mais elevados, comparativamente às questões de resposta aberta. Identificaram-se duas variáveis explicativas para os valores DPP: o rendimento e a ocupação principal. A sensibilidade dos respondentes à magnitude dos ganhos em saúde foi verificada internamente em cada questionário (os participantes referiram DPP mais elevadas no cenário 2 relativamente ao cenário 1), no entanto, os participantes que beneficiariam mais da intervenção não demonstraram DPP superiores aos restantes. Para confirmar os efeitos identificados neste estudo e extrapolá-los para a população portuguesa é necessário realizar um estudo representativo de população portuguesa.

Corporate social responsibility

There is general consensus nowadays that CSR is not just altruistic do-gooding but rather a way for both companies and society to prosper. Companies themselves increasingly recognize that their sustainability depends on their willingness to assume responsibility for social and environmental issues. Academic research has, in the past, tried to theorize exactly how CSR improves business, employee satisfaction and productivity. However, few studies have a) separated the different effects of internal CSR and external CSR and b) studied these effects in times of internal organizational distrust. Hence, this paper examines the relationship between each type of CSR with two outcome variables related to employee attitudes: affective organizational commitment (AOC) and turnover intentions (TI). Furthermore, it investigates whether organizational distrust works as a moderator in each of these relationships by testing the hypothesis using a sample of 212 employees from a company that is currently going through a moment of internal crisis. Findings suggest that although all variables are strongly correlated, distrust works as a moderator for external CSR but not for internal CSR. The theoretical and practical implications of these findings conclude the paper.

The role of guarantees in pension plan design: Pension saving decisions

This study centers on the assessment of psychological value of guarantees in pension products and the behavior biases associated with choice. When a guarantee on a product increases from 99% to 99,5% less than half of respondents show willingness to pay in contrast with 73% when going from 99,5% to 100%. Out of 105 respondents, 55 show that their choices concerning pension products are inconsistent with classic utility theory. Financial background proves insignificant thus pointing to behavioral biases. As individuals make choices that leave them worse-off, we argue that pension plan design would highly benefit from public policy interventions.

Community indentification in peer-t-peer collaborative consumption services

Even though collaborative consumption (CC) is gaining economic importance, research in CC is still in its infancy. Consumers’ reasons for participating have already been investigated but little research on consequences of participation has been conducted. This article examines whether interactions between customers in peer-to-peer CC services influence the willingness to coproduce service outcomes. Drawing on social exchange theory, it is proposed that this effect is mediated by consumers’ identification with the brand community. Furthermore, continuance intention in CC is introduced as a second stage moderator. In a cross-sectional study, customers of peer-to-peer accommodation sharing are surveyed. While customer-to-customer interactions were found to have a positive effect on brand community identification, brand community identification did not positively affect co-production intention. Surprisingly, the effect of brand community identification on co-production intention was negative. Moreover, continuance intention of customers did not moderate this relationship. Bearing in mind current challenges for researchers and companies, theoretical and managerial implications are discussed.

Finding the hidden influencers

This thesis is a first step in the search for the characteristics of funders, and the underlying motivation that drives them to participate in crowdfunding. The purpose of the study is to identify demographics and psychographics that influence a funder’s willingness to financially support a crowdfunding project (WFS). Crowdfunding, crowdsourcing and donation literature are combined to create a conceptual model in which age, gender, altruism and income, together with several control variables, are expected to have an influence on a funder’s WFS. Primary data collection was conducted using a survey, and a dataset of 175 potential crowdfunders was created. The data is analysed using a multiple regression and provided several interesting results. First of all, age and gender have a significant effect on WFS, males and young adults until the age of 30 have a higher intention to give money to crowdfunding projects. Second, altruism is significantly positively related to WFS, meaning that the funders do not just care about the potential rewards they could receive, but also about the benefits that they create for the entrepreneur and the people affected by the crowdfunding project. Third, the moderation effect of income was found to be insignificant in this model. It shows that income does not affect the strength of the relationship between the age, gender and altruism, and WFS. This study provides important theoretical contributions by, to the best of my knowledge, being the first study to quantitatively investigate the characteristics of funders and using the funder as the unit of analysis. Moreover, the study provides important insights for entrepreneurs who wish to target the crowd better in order to attract and retain more funders, thereby increasing the chance of success of their project.
