Publicação Acesso Aberto Predictive power of the term structure of interest rates over recessions in Europe2014 - Pinho, Carlos; Madaleno, Mara; Rodríguez de Prado, Francisco; Maldonado, IsabelThis work intends to infer for European countries the extent that anticipations of the term structure of interest rates has over recessions, as measured by factor models. For that, we model the shape of the yield curve by latent factors corresponding to its level, slope and curvature. The simple and modified probit and logit models are used to examine the yield curve’s ability to forecast economic downturns (recessions). Despite official recessions dates being available at the Centre for Economic Policy Research (CEPR), which recently formed a committee to set the dates of the Euro area business cycle in a manner similar to the NBER, these are based on aggregate data. So, we determine the recessions using the BBQ methodology to have them dated for each individual country in the sample. The findings suggest that the yield curve components predict recessions for more than one year ahead, with increased goodness of fit when the autoregressive term is included as explanatory variable. These results are consistent for both UK, Germany and Portugal.Publicação Acesso Aberto Recessions in Portugal: the predictive power of term structure of interest rates components2018 - Pinho, Carlos; Maldonado, IsabelIn this paper we present a study of the predictive ability of the term structure of interest rates over future recessions in Portugal. The analysis will be based on factor models in which the term structure of interest rates is determined by latent factors, corresponding to their level, slope and curvature. Simple and modified probit and logit models will be used to examine the forecasting ability of term structure in predicting economic crises (recessions). Recession periods were determined based on the methodology proposed by Bry and Boschan. Our results suggest that all term structure of interest rates components allow to predict recessions in one-year time horizons, with an increase in adjustment quality when we include an autoregressive term as the explanatory variable.Publicação Acesso Aberto Big data and financial auditing in Portugal2020-07-15 - Cláudio, Miriam; Pinho, Carlos; Maldonado, IsabelOver time, new instruments have been developed that allow us to collect, store, process and analyse more and more information. However, financial auditors are faced with what is now called the Big Data phenomenon. The objective of this article is to determine the impact that Big Data is having on financial auditing in Portugal and how auditors perceive this new scenario. For this purpose, a questionnaire was prepared and released among Portuguese professional auditors. According to the results obtained, most of the respondents are familiar with the Big Data concept but also consider that the information currently collected is sufficient to support auditing conclusions. These professionals assume that they feel limitations when faced with large amounts of data and that the current tools are not prepared for the analysis of large amounts of data, not to mention Big Data analysis. Regarding the efforts that can be made to increase knowledge of the Big Data in the auditing profession, the great majority are not aware of any professional or complementary training that mentioned the Big Data theme provided by the professional order. Our responses analysis leads to conclude that despite the impact that Big Data is having on society in general, a large number of audit professionals in Portugal are still not prepared to deal with this phenomenon.Publicação Acesso Aberto Inducing factors that can affect the success of internationalization: Comparative study for Portuguese firms2019 - Maldonado, Isabel; Pacheco, Luís Miguel; Lobo, Carla AzevedoThe challenges that companies face in their internationalization strategy are naturally demanding. If we think that this strategy is no longer exclusive to large companies, we can easily understand all the research that has been carried out on this subject and more specifically on the approach to SMEs. Even so, little has been discussed about the relationship that can be established between the different strategic approaches to internationalization and the factors that entrepreneurs most value in this entrepreneurial process. Based on an exhaustive literature review, in addition to determining the driving factors of the internationalization strategy that Portuguese entrepreneurs most value, this research aims to assess, through a comparative study between the entrepreneurs' perspectives in 2014 and 2019, the possible oscillations in the international strategies of Portuguese entrepreneurs during the period of economic crisis (2014) and a post-crisis period (2019). To achieve these objectives, we used data from a questionnaire sent to "exporting companies and/or companies interested in exporting" from the AICEP - Portugal Global Database, in 2014 and later in 2019.Publicação Acesso Aberto Do ISO certifications enhance internationalization? The case of portuguese industrial SMEs2022-01-25 - Maldonado, Isabel; Lobo, Carla Azevedo; Pacheco, Luís MiguelIn the last decades, the academic literature has devoted considerable attention to the determinants of export performance. In result of those research efforts in identifying and examining the influence of such determinants, the literature presents a wide set of variables associated with higher levels of exports. This paper provides a contribution to that literature by trying to evidence the impact of firm certification—namely, in terms of the firm’s quality, environmental, and health and safety management systems—on export performance. The paper analyses an unbalanced sample of 1684 Portuguese industrial SMEs for the period 2010 to 2020, uses other determinants of internationalization as control variables, and explores the possibility of moderating effects on the certification–internationalization relationship. Two alternative econometric methods are employed: a random-effects model and a Tobit model. The results evidence the importance for firms, especially in the low or medium–low technology sectors, to have certain ISO certifications in order to further develop their export activities and increase their foreign acceptance, particularly in the European Union markets. Further, certification seems to reinforce the positive relation between firm size and internationalization.Publicação Acesso Aberto International diversification of SMEs: The role of foreign capital2019-10 - Pacheco, Luís Miguel; Maldonado, Isabel; Lobo, Carla AzevedoThe aim of this paper is to empirically examine the relationship between the firms’ ownership and control structure, in particular the presence of foreign capital, and their internationalization levels. The internationalization of Portuguese SMEs depends on a multitude of factors, being the impact of foreign investment inflows directed to industrial SMEs a usually forgotten factor. This paper fills that gap using a balanced panel data of 5,722 firms for an eight year period beginning in 2010, researching if the presence of foreign capital influences the level and scope of internationalization, and controlling for the effects of variables such as profitability, age, size, indebtedness and sector of activity. The country of origin of the foreign capital is considered and possible non-linear effects are also tested. The results evidence that the presence in SMEs of foreign shareholders positively influences internationalization. Also, there seems to exist a non-linear relation between the development level of the country of origin of the share capital and internationalization, with the results indicating that firms with capital originated from more advanced countries attain a higher degree of internationalization.Publicação Acesso Aberto Business internationalization inducing factors: The importance of knowledge and relational networks2017 - Lobo, Carla Azevedo; Maldonado, IsabelCompanies are currently required to continually innovate and restructure their operations in order to respond to the requirements of national and international competition. Companies have to find new ways to develop competitive advantages and acquire new skills, resources and capabilities. Based on the opinions of different factors considered as inducers of the internationalization process by companies that internationalized early in their life cycle. We developed an empirical study with 320 portuguese international firms and used the statistical software AMOS for a confirmatory factor analysis. We propose a Theoretical Model in accordance to Human Capital Theory, International New Ventures Theory, and the Population Ecology Approach. We find evidence of the importance of Networks, Specific Skills of its workers, International Experience of its workers and Entrepreneurial Propensity and to Take Risks from workers and top management team.Publicação Acesso Aberto Early internationalization enhancing factors: Comparative study for Portuguese firms between 2014 and 20192020 - Maldonado, Isabel; Pacheco, Luís Miguel; Lobo, Carla AzevedoCom base numa revisão exaustiva da literatura esta investigação pretende averiguar qual a importância atribuída a diversos fatores considerados potenciadores/indutores do processo de internacionalização por parte das empresas que se internacionalizam cedo no seu ciclo de vida, utilizando a avaliação das opiniões dos próprios empresários. São considerados fatores como as redes relacionais, as competências específicas dos empresários e a experiência internacional dos colaboradores. Esta investigação pretende, para além de determinar quais os fatores impulsionadores da estratégia de internacionalização destas empresas, aferir, através de um estudo comparado entre as perspetivas dos empresários em 2014 e em 2019, das possíveis oscilações nas estratégias internacionais dos empresários portugueses, durante o período de crise económica (2014) e um período pós-crise (2019). Para atingir estes objetivos utilizamos os dados de um questionário enviado para as “empresas exportadoras e/ou com interesse em exportar” da Base de Dados da AICEP - Portugal Global, em 2014 e posteriormente em 2019. Pretende-se assim confirmar os anteriores resultados em que foram encontradas evidências da importância para os empresários portugueses das Redes Relacionais, bem como das Competências Específicas dos Colaboradores, da Experiência Internacional dos Colaboradores, em consonância com a Teoria das Redes, a Teoria do Capital Humano, a Teoria das International New Ventures, a Population Ecology Approach e com a Attention Based View.Publicação Acesso Aberto Interest rates dynamics: Contribution of macroeconomic information in four European markets2017 - Pinho, Carlos; Rodríguez de Prado, Francisco; Maldonado, Isabel; Lobo, Carla AzevedoOral presentation in the XIII Iberian International Business Conference (IICB17), Instituto Universitário de Lisboa, Portugal, 20-21 October 2017, with the title Interest rates dynamics: Contribution of macroeconomic information in four European markets.Publicação Acesso Aberto Downside risk in commodity and equity markets2019 - Pinho, Carlos; Maldonado, IsabelThe aim of the present study is to analyse the tail risk of global commodities indices and a set of share indexes of several countries and regions. To measure the downside risk we use two tail risk measures, namely the Value-at-Risk (VaR) and the Conditional Value-at-Risk (CvaR), determined by parametric, semi-parametric and non-parametric approaches. Using daily prices comprising the period from January of 2002 to December 2016 and considering the pre- and post-global financial crisis sub-periods. A time-varying correlation between stock and commodity markets returns, comparing returns and downside risk measures was carry out. Overall, our findings indicate that tail risk of commodity markets is higher than stock market over the period, for almost all commodities, but that over the crisis period analysed the tail risk of stock market indices sharply increases to the same levels of commodities tail risk. The correlations between commodity and stock returns evolve through time. Considering the tail risk measures, for all analysed pairs, commodity and stock returns, we observe very high contemporaneous correlations during the crisis period.
