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 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.Publicação Acesso Aberto Volatility and return spillovers across commodity and equity markets2022-01 - Pinho, Carlos; Maldonado, IsabelThis paper presents an empirical analysis of the relationship between commodity market shocks and stock markets. [...]Publicação Acesso Aberto Interest rate dynamic models: Evidence from Iberian markets2018 - Pinho, Carlos; Rodríguez de Prado, Francisco; Lobo, Carla Azevedo; Maldonado, IsabelIn this paper we investigate the yield curve forecasting performance of dynamic models combining yield curve factors and macroeconomic variables. We test dynamic models using sovereign debt data, inflation rate and annual variation of the industrial production index for Portugal and Spain. We also explore the dynamic correlations between the yield curve factors of the countries under analysis. Results indicate that the consideration of macroeconomic factors has a positive contribution to the improvement of forecasts. The analysis shows a strong correlation between the two countries level factor and important changes in the curvature factor correlations associated with international crisis episodes.Publicação Acesso Aberto The impact of ECB announcements on the Eurozone financial markets2017 - Pinho, Carlos; Sousa, Clara Filipa Ferreira de; Maldonado, IsabelIn this work we analyze the reaction of financial markets, shareholders and bondholders of the euro area, to monetary policy announcements by the European Central Bank (ECB). The research was based on the event study methodology, based on 91 notices relating to monetary policy, issued during the period 1 January 2008 to 31 December 2012. The results provide some empirical evidence of the information content of monetary policy announcements, as we found evidence of abnormal returns around the announcement day. The results show that markets react differently to good and bad news. The results also indicate different reactions of different euro zone countries to the same announcements. In the euro area, the news of ECB monetary policy, have a greater impact on the bond market than on the equity market.Publicação Acesso Aberto Co-movements between financial and commodity markets2017 - Pinho, Carlos; Maldonado, IsabelIn this paper we aim to assess the dynamics of commodities ad stock markets at time-frequency domain. Our data set consists of monthly IMF commodity price indices and sub-indices, and the Morgan Stanley Capital International (MSCI) World Stock Index between January 1993 and March 2016. Among others, our results indicate a significant increase in synchronization of procyclical pattern, with periodicities of one to four years, during the recent subprime and financial crisis. The results presented in the paper could help investors to design investment strategies in commodity markets.Publicação Acesso Aberto Distance learning of financial accounting: Mature undergraduate students’ perceptions2023-04-02 - Silva, Ana Paula; Magalhães, Miguel; Pinho, Carlos; Pereira, Manuel Sousa; Torre, Lígia; Maldonado, IsabelThis research sought to explore self-reported satisfaction levels of mature students enrolled in the virtual financial accounting course of the first online-only bachelor’s degree in Portugal. While doing so, it attempted to generate understanding of which factors may affect undergraduate mature students’ engagement—herein measured in terms of overall satisfaction—with online learning, particularly, of financial accounting. Thereby, this research addresses several research gaps. First, unlike most recent empirical research, it provides evidence from a post-pandemic period, in 2022. Second, responding to calls for further education research in different contexts, Portugal poses a highly relevant, unexplored research setting since it was only in 2019 that the Portuguese government approved a legal regime to frame distance education at Higher Education Institutions (HEIs). Third, this research focuses on the overlooked, and yet growing, population of adult mature students. The research evidence emerges from 32 valid responses to a structured electronic questionnaire circulated to students at the end of a financial accounting module (in July 2022). Satisfaction rates from students’ own perspectives were derived in terms of (i) overall satisfaction, (ii) learning outcomes, (iii) e-learning process, and (iv) pedagogical practices adopted. The assessment of satisfaction levels was determined through Likert-type items with responses ranging from a minimum score of 1 to the highest score of 5. Data gathered were subject to quantitative analysis: descriptive statistics, Pearson correlations, statistical tests, principal component analysis, and linear regression. High levels of satisfaction with distance education were uncovered. We found that pedagogical practices constitute the dimension that contributed the least (though, still importantly) to overall satisfaction as compared with learning outcomes and e-learning process. The results of this research offer the potential to contribute to the implementation of training offerings of online courses at other Portuguese HEIs as well as abroad.
