    Predictive power of the term structure of interest rates over recessions in Europe
    2014 - Pinho, Carlos; Madaleno, Mara; Rodríguez de Prado, Francisco; Maldonado, Isabel
    This 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.

    Recessions in Portugal: the predictive power of term structure of interest rates components
    2018 - Pinho, Carlos; Maldonado, Isabel
    In 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.

    The goodwill relevance in cash flow forecasting: The Portuguese case
    2019 - Pinho, Carlos; Maldonado, Isabel
    This study aims to analyse in what extent goodwill and goodwill impairment losses are relevant to the flows forecasting in Portugal. We explore the goodwill and goodwill impairments losses forecasting ability to predict cash flows using multiple linear regression models with one-year-ahead cash flows as a dependent variable in each regression model and including the goodwill and goodwill impairment losses in the independent variables. Our sample includes Portuguese companies consolidated annual reports belonging to the PSI-20 index and covers the period between 2010 and 2017. Regression results from the estimated models show that our key variable goodwill is statistically significant, indicating that the goodwill have significant predictive ability for one-year ahead cash flows being an important variable to consider by the users of financial statements in forecasting future cash flows and in making economic decisions. The reported goodwill impairment losses results reveal a significative and negative sign for its estimated coefficient. However, the estimates coefficient on goodwill is negative, raising the question whether the goodwill reported by Portuguese entities is really perceived as an "productive asset" or not.

    Big data and financial auditing in Portugal
    2020-07-15 - Cláudio, Miriam; Pinho, Carlos; Maldonado, Isabel
    Over 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.

    Downside risk in commodity and equity markets
    2019 - Pinho, Carlos; Maldonado, Isabel
    The 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.

    International new ventures and early internationalization: Networks and skills as enhancing agents
    2019-01-28 - Pinho, Carlos; Maldonado, Isabel; Lobo, Carla Azevedo
    The skills of the employees, and for the International Experience of employees, in line with the chosen Theoretical Model. current research on international new ventures has been trying to understand the processes that support companies in their decision to early enter foreign markets. The role of learning and knowledge as become one of the arising topics in the literature. Recent empirical evidences provide important insights on the internationalization of new business. Younger firms are able to compensate their limited experiential learning at company level, through learning based on previous experiences of the management team, and through inter-organizational relationships (vicarious learning). The most common type of vicarious learning discussed in conceptual and empirical works involves learning with a network: depending on the position of a company in the network, this will define its range of opportunities and constraints and these relationships have a strong impact on market selection as well as on entry mode because they make it easier to identify and exploit new opportunities. Based on the opinions of different entrepreneurs, this study seeks to determine the importance of several factors as inducers of the internationalization process by companies that have internationalized early in their life cycle. Factors such as the relational networks, entrepreneurs’ specific skills and international experience of employees are considered. The empirical study was conducted on a sample of 320 Portuguese companies. Data Exploratory Analysis methodologies and Univariate Statistical Inference methodologies were used. Evidence was found for the importance of Relational Networks, for Specific.

    Forecasting the yield curve with macroeconomic information: evidence from European markets
    2021 - Pinho, Carlos; Rodríguez de Prado, Francisco; Maldonado, Isabel; Lobo, Carla Azevedo
    In this paper we analyse the predictive content of the introduction of macroeconomic variables in term structure dynamic models. We tested the dynamic models using data from the public debt, inflation rate and annual variation of the industrial production index for four European countries: Portugal, Spain, the United Kingdom and Germany. Results obtained for the period from January 1990 to December 2012 indicate that considering macroeconomic factors makes a positive contribution to the improvement of forecasts for different countries and maturities. However, the paper presents evidence of time-varying forecast accuracy, not only across yield maturities and forecast horizons, but also over data subperiods.

    Yield curve dynamics and the performance of Iberian economies
    2020-11-26 - Pinho, Carlos; Maldonado, Isabel
    The aim of this paper is to analyze the bidirectional relation between the term structure of interest rates components and macroeconomic factors. Using a factor augmented vector autoregressive model, impulse response functions and forecasting error variance decompositions we find evidence of a bidirectional relation between yield curve factors and the macroeconomic factors, with increased relevance of yield factors over it with increased forecasting horizons. The study was conducted for two Iberian countries using information of public debt interest rates of Spain and Portugal and macroeconomic factors extracted from a set of macroeconomic variables, including indicators of activity, prices and confidence. Results show that the inclusion of confidence and macroeconomic factors in the analysis of the relationship between macroeconomics and interest rate structure is extremely relevant. The results obtained allow us to conclude that there is a strong impact of changes in macroeconomic factors on the term structure of interest rates, as well as a significant impact factor of the term structure, in the future evolution of macroeconomic factors.
