The expectations hypothesis of the term structure: some empirical evidence for Portugal

The purpose of this paper is to test the (rational) expectations hypothesis of the term structure of interest rates using Portuguese data for the interbank money market. The results obtained support only a very weak, long-run or "asymptotic" version of the hypothesis, and broadly agree with previous evidence for other countries. The empirical evidence supports the cointegration of Portuguese rates and the "puzzle" well known in the literature: although its forecasts of future short-term rates are in the correct direction, the spread between longer and shorter rates fails to forecast future longer rates. In the single equation framework, the implications of the hypothesis in terms of the predictive ability of the spread are also clearly rejected

Short and long run tests of the expectations hypothesis: the Portuguese case

The purpose of this paper is to test both short- and long-run implications of the (rational) expectations hypothesis of the term structure of interest rates using Portuguese data for the interbank money market. The results support only a very weak, long-run or "asymptotic" version of the hypothesis, and broadly agree with previous (but separate) evidence for other countries. Empirical evidence supports the cointegration of Portuguese rates and the "puzzle" well known in the literature: although its forecasts of future short-term rates are in the correct direction, the spread between longer and shorter rates fails to forecast future longer rates. Further short-run implications of the hypothesis in terms of the predictive ability of the spread are also clearly rejected, even for the more stable period which emerged in the middle nineties.Term structure; Expectations hypothesis; Hypothesis testing; Structural breaks; Portugal

Embedding a regular subpencil into a general linear pencil

AbstractWe study the possible strictly equivalence classes of a pencil when a regular subpencil is prescribed. We also study the possible invariant polynomials and the possible characteristic polynomials of A+BY+XC+XDY when X and Y vary

Should I stay or should I go?: a managerial toolbox for the 21st century SMEs

The rise of new technologies reshaped the way firms face new challenges. Consequently, companies in small open economies, namely SMEs, are more susceptible to environmental changes, therefore they must develop new ways to adapt to the continuous transformations that characterize the business environment. This way, expanding to other geographies is the optimal solution to the generation of new business and adaptation of the existing ones. When internationalizing, firms face the decision of how to enter new markets, and sometimes managers lack the acknowledgment of which advantages and drawbacks are at stake. Consequently, this paper aims to present a systematized toolbox that will guide decision-makers, when developing their internationalization strategies.info:eu-repo/semantics/publishedVersio

Patterns of antenal sensilla of Panstrongylus megistus from three Brazilian states

The objective of the present study was to analyze and describe the phenotype of the antennal sensilla of Panstrongylus megistus, one of the epidemiologically most important species of triatomines in Brazil. Specimens from the Brazilian states of Goiás (GO), Minas Gerais (MG), and Rio Grande do Sul (RS) were compared, based on studies of four types of sensilla on three antennal segments: thick-walled trichoid (TK), thin-walled trichoid (TH), bristles (BR), and basiconica (BA). Discriminant analysis allowed the separation of the RS specimens from those of GO and MG. Multivariate discriminant analysis demonstrated that the sensilla of males differed from those of females, the variables with greatest weight being the BA of all three segments and the TK of flagellum 1. The basiconica sensilla were significantly more abundant in females, on all three segments. Antennal sensilla patterns also demonstrated significant differences among P. megistus specimens.Fil: Villela, M. M.. Fundación Oswaldo Cruz; BrasilFil: Catala, Silvia Susana.

Como as mídias sociais afetam as intenções de compra das consumidoras femininas em Macau: assistindo a vídeos de experiência de produtos de beleza e cosméticos no YouTube

YouTube has become increasingly popular for marketing purposes. As corporate and user-generated content is widely available on this platform, beauty-related professionals need to understand how to create videos that make their products more appealing and stand out from the clutter. In this study, we examine four factors (i.e., perceived usefulness of the information, perceived credibility of the information, attitude toward the purchase, and perceived video characteristics) that affect the purchase intentions of female consumers. After viewing beauty-related videos, a sample of 204 female consumers was analyzed by structural equation modeling. The findings showed that videos with more views, likes, and comments tend to have a greater effect on the respondents' intentions to purchase. Also, the factors of perceived usefulness of the information, perceived credibility of the information, and attitude toward the purchase exhibited a significant effect on the intention to buy beauty-related products. The result showed that perceived video characteristics (such as quality and visuals) did not significantly influence the purchase intention, however, there is evidence that this factor should not be ignored by content creators. Finally, our research provides insights, strategies, and future directions for industry practitioners and marketers.O YouTube tem se tornado cada vez mais popular para fins de marketing. Como o conteúdo corporativo e gerado pelo usuário está amplamente disponível nesta plataforma, os profissionais relacionados à beleza precisam entender como criar vídeos que tornem seus produtos mais atraentes e se destaquem da desordem. Neste estudo, examinamos quatro fatores (ou seja, percepção da utilidade da informação, percepção da credibilidade da informação, atitude em relação à compra e percepção das características do vídeo) que afetam as intenções de compra das consumidoras femininas. Após a visualização dos vídeos relacionados à beleza, uma amostra de 204 consumidoras femininas foi analisada por meio de modelagem de equações estruturais. Os resultados mostraram que vídeos com mais visualizações, curtidas e comentários tendem a ter um efeito maior sobre as intenções de compra das entrevistadas. Além disso, os fatores de percepção da utilidade da informação, percepção da credibilidade da informação e atitude em relação à compra demonstraram um efeito significativo sobre a intenção de compra de produtos relacionados à beleza. O resultado mostrou que as características do vídeo percebido (como qualidade e visuais) não influenciaram significativamente a intenção de compra, no entanto, há evidências de que este fator não deve ser ignorado pelos criadores de conteúdo. Finalmente, nossa pesquisa fornece insights, estratégias e direções futuras para os profissionais da indústria e marqueteiros.info:eu-repo/semantics/publishedVersio

The role of environmental concern and technology show-off on electric vehicles adoption: the case of Macau

Purpose: Research on battery electric vehicles (BEVs) has typically considered environmental concern a key determinant of behavioral intention that leads individuals to prefer electric vehicles. This paper challenges this assumption and argues that technology frameworks may require new variables to capture consumers' preferences. A UTAUT2-based study has been developed to assess the role of environmental concern in the BEVs context and put forward the technology show-off (TS) concept to explain the technology's acceptance. Design/methodology/approach: A quantitative and cross-sectional look at behavioral intention is adopted. The study uses structural equation modeling to analyze a sample of 236 Macau residents to determine the relevance of the factors behind the choice to adopt BEVs. Findings: The findings indicate that environmental concern and price may be relevant to explain behavioral intention to adopt the BEVs technology. Furthermore, the UTAUT2 framework seems to benefit from adding new variables, with TS playing a pertinent role in explaining technology acceptance. Social implications: The findings show that environmental concern fails to build an argument for the shift to full electric mobility and promote the desired behavioral change toward adopting BEVs. Herein lies the necessity to consider new variables that can better describe the characteristics of modern society.Originality/value: This paper proposes the TS construct, combining visibility and trialability as significant determinants of behavioral intention to use technology. The study also stresses the need to reconsider the role of environmental concerns' impact on consumer decision-making.info:eu-repo/semantics/acceptedVersio
