Understanding the Relationship between Consumption and Happiness: Quantitative Research in Portugal Bruna LOPES, Paulo PINTO-MOREIRA, Manuela LARGUINHO Ibima Business Review, 2025 Can consumption generate happiness, or is it time to question this premise and seek a deeper understanding of the true pillars of human achievement? To answer this question, we examined how consumption is represented as a pathway to happiness, and the factors that influence this link. The types of material and experiential consumption and their relationship with the happiness of consumption were studied, as well as social approval, as it is one of the most relevant factors for those who seek happiness through consumption. Quantitative research was conducted with data collection by questionnaire in a sample of 525 respondents. The results found support that it is material consumption that reveals a direct effect on consumption happiness. Social approval has not been shown to have a direct effect on consumer happiness. Consumer happiness, in turn, has not been shown to contribute to happiness. However, concerning the types of consumption, there was a direct relationship between experiential consumption and happiness. From the results obtained, we speculate the justification by changes in consumption patterns and consumers’ evolution, who have become more intelligent and demanding.
An Empirical Study on Virtual Team Leadership Perception Bárbara FERREIRA, Paulo PINTO-MOREIRA, Manuela LARGUINHO Ibima Business Review, 2023 Virtual work is one of the most important organizational issues of present times. The growing demands of organizational competitive advantage observed in the current scenario in a global and digital context, where people are increasingly physically distant, new and demanding challenges are posed to employees and companies, particularly with regard to the development of teleworking activities and the respective virtual leadership (e-leadership).
Analysing the Influence of Green Marketing Communication in Consumers’ Green Purchase Behaviour Elisabete Correia, Sara Sousa, Clara Viseu, Manuela Larguinho International Journal of Environmental Research and Public Health, 2023 This study aims to explore whether consumers’ attention to companies’ green marketing communication influences their green purchase behaviour. It also analyses the importance of consumers’ characteristics, namely gender, education, and green attitudes, in their attention to companies’ green marketing communication. An online survey was carried out on the population residing in Portugal over 18 years of age, allowing us to collect 690 valid responses. Data analysis techniques including descriptive analyses, parametric and non-parametric tests, linear correlation, and regression analysis were used. The achieved results allow us to conclude that consumers are attentive to companies’ green marketing communication. A strong correlation between consumers’ attention to companies’ green marketing communication and green purchasing behaviour was identified. The results also confirm that individuals with higher educational levels and green attitudes and females are the most attentive to companies’ green marketing communication.
Analysing the Influence of Companies’ Green Communication in College Students’ Green Purchase Behaviour: An Application of the Extended Theory of Planned Behaviour Model Sara Sousa, Elisabete Correia, Clara Viseu, Manuela Larguinho Administrative Sciences, 2022 In recent years, there has been a growing concern about the environmental impacts of consumers’ behaviour. As this environmental awareness increases, consumers tend to focus more on green products and how purchasing these products represents an effective way to protect the environment. Through the application of the theory of planned behaviour (TPB), in this research, we studied the influence of some key variables on college students’ green purchasing behaviour, namely perceived behavioural control, subjective norms, green attitudes, and green purchase intentions. The TPB model was extended to the analysis of the influence of the companies’ green communication on students’ green purchase behaviour. To achieve the proposed goal, from March to April of 2021, a survey was conducted among the students of a higher education institution (HEI) in Portugal, allowing us to gather 432 valid responses. The findings suggested that all the variables, except the subjective norms, had a positive influence on the students’ green purchase intentions. Moreover, it was observed that students’ intentions had a positive influence on their green purchase behaviour. This research provides important results not only for policymakers to promote more sustainable behaviours among consumers but also for companies to be more aware of the importance of green communication.

Valuation of bond options under the cir model: Some computational remarks Manuela Larguinho, José Carlos Dias, Carlos A. Braumann Studies in Theoretical and Applied Statistics Selected Papers of the Statistical Societies, 2014 Pricing bond options under the Cox, Ingersoll and Ross (CIR) model of the term structure of interest rates requires the computation of the noncentral chi-square distribution function. In this article, we compare the performance in terms of accuracy and computational time of alternative methods for computing such probability distributions against an externally tested benchmark. All methods are generally accurate over a wide range of parameters that are frequently needed for pricing bond options, though they all present relevant differences in terms of running times. The iterative procedure of Benton and Krishnamoorthy (Comput. Stat. Data Anal. 43:249–267, 2003) is the most efficient in terms of accuracy and computational burden for determining bond option prices under the CIR assumption.
On the computation of option prices and Greeks under the CEV model MANUELA LARGUINHO, JOSÉ CARLOS DIAS, CARLOS A. BRAUMANN Quantitative Finance, 2013 Pricing options and evaluating Greeks under the constant elasticity of variance (CEV) model requires the computation of the non-central chi-square distribution function. In this article, we compare the performance, in terms of accuracy and computational time, of alternative methods for computing such probability distributions against an externally tested benchmark. In addition, we present closed-form solutions for computing Greek measures under the unrestricted CEV option pricing model, thus being able to accommodate direct leverage effects as well as inverse leverage effects that are frequently observed in options markets.
