This paper aims to analyze the determinants of Portuguese energy companies' performance.

To achieve our objective, we have used data from 457 Portuguese energy companies, in the period between 2011 and 2018. Three dependent variables were tested using panel data, through the generalized method of moments (GMM) estimation method.

The results point out that the determinants of companies' performance change according to how different stakeholders appreciate corporate performance. In general, shareholders are concerned with maintaining their levels of profitability over time as well as with the company's market image. Managers are centered on maintaining solid margins on EBITDA through good management of cash flow, leverage and current assets. For the rest of the stakeholders, including global society, debt and investments in tangible fixed assets reduce profitability while investments in immaterial assets help to create value and performance for energy companies.

As far as the authors are aware, this is the first time that a study has been carried out in the Portuguese energy sector using the GMM-system model for three different stakeholders' views of corporate performance determinants.

The main goal of this paper is better understand the risk/return trade-off of investing in socially responsible investment funds (SRIF) and green investment funds (GIF).

To achieve our aim a green investment fund portfolio, a socially responsible investment portfolio and a conventional fund (CF) portfolio from the United States of America (USA) were selected to compare the efficiency of these three different portfolios, by using Value-Based Data Envelopment Analysis (DEA) methodology.

The results point out that SRIF and GIF are more efficient than CF. For five years, the CFs have not outperformed the GIF.

The results suggest that there is a growing awareness on the part of investors that sustainable companies are the companies that will allow a better quality of life and a more sustainable environment. It seems that somehow managers and investors are aware that the market will compensate them for thinking about a cleaner and more equitable world.

The main objective of this work is to show that the traditional specific characteristics of companies as well as cultural and religious dimensions can influence the leverage of companies in different macro-environmental systems.

To achieve this aim, the authors have used data from 1.568 firms from 7 European countries between 2010 and 2016, and the models were estimated by using panel data methodology, specifically the generalized method of moments (GMM) estimation method by Arellano and Bover (1995) and Blundell and Bond (1998).

Overall, the empirical results point out that the cultural moderating factors are essential in determining companies' capital structure, regardless of the country's legal origin. The study results also show that traditional variables, intrinsic to management, macroeconomic environment and religion, have a central role in capital structure, namely for the civilian countries.

As far as the authors know, this is the first work that uses, in addition to the traditional specific characteristics of companies, cultural dimensions and religion, as determinants of debt levels, in different legal systems for Europe.

This study aims to understand which factors determine the corporate performance of Portuguese and Spanish listed companies between 2011 and 2018, also considering the sub-period marked by the presence of the Troika in Portugal, between 2011 and 2014.

To achieve this aim, panel data methodology was used, specifically the generalized method of moments (GMM) estimation method proposed by Arellano and Bond (1991), Arellano and Bover (1995) and Blundell and Bond (1998) for 110 non-financial companies from the Iberian Peninsula.

The results point out different signs and significance of the variables in the companies of the two countries. Regarding the sub-period, our results suggest that the intervention of the Troika in Portugal acted in a very different way from the neighboring country.

This research shows the importance of studying countries individually, even with small dimensions, to reinforce the path that is still necessary for more sustainable companies. Furthermore, when companies have strong governance structures, the harmful contagion from one neighboring country to another may not happen.

The main goal of this paper is to study the specific characteristics of the performance of companies in the metallurgical sector, in the northern region of Portugal.

To achieve this aim, the authors have used data from 325 companies manufacturing metal products, except machinery and equipment (CAE Rev.3 25) and 27 companies that manufacture machinery and equipment (CAE Rev. 3 28). The models were estimated by using the panel data methodology for the period between 2011 and 2019. Specifically, the estimation method of the generalized method of moments system (GMM system) proposed by Arellano and Bover (1995) and Blundell and Bond (1998) was used.

The results show that the main decisions on the performance of metallurgical companies in Northern Portugal depend on the dimensions of sales in the domestic market (SDM), sales in the community market (SCM), and sales in the foreign market (SFM) and also highlight that the signal and significance of the specific variables depends on how the different stakeholders understand performance.

As far as the authors know, this is the first study to comparatively analyze the two metallurgical databases in Portugal. Despite the huge difference in the size of the sample, this study’s results show that in an era of paradigm shift about what business objectives should be, stakeholders are still not environmentally aware and the social dimension is only considered by shareholders, but not yet by the manager and the general community.

This paper aims to analyze the impact of the adoption of ISO 14001 and ISO 9001 on the performance of Portuguese companies. The sample includes the companies listed on Euronext Lisbon, with economic, financial and specific information – the specific being environmental information and quality information – for the period between 2015 and 2019, which corresponds to the post-Troika period when some economic growth started to be witnessed. The specific information of each area is translated into the environmental certification by the ISO 14001 standard, the quality certification by the ISO 9001 standard, and sustainability reports.

To achieve this aim, four variables were used as a measure of the companies' performance, Return on Assets (ROA), Return on Equity (ROE); Tobin's Q and EBITDA Margin. With this data, different panel models were tested to validate if ISO 9001 and ISO 14001 certifications impact Portuguese listed companies performance. Specifically, the authors have used the Generalized Method of Moments, GMM-System, an estimation method proposed by Arellano and Bover (1995) and Blundell and Bond (1998).

The results show that, in general, the environment and quality variables fail to explain the dependent variables, that is, ISO certifications do not provide positive or negative variations in the performance of companies, suggesting that they are not yet as much for civil society, as well as for current or potential shareholders. When used as an independent variable, certification according to the ISO 14001 or 9001 standards, negative and significant oscillations were verified in the dependent variable, MgEBITDA, suggesting that only for managers this variable is determinant, but with a negative impact, given the high costs, it entails without pressure from other stakeholders.

This study is the first to analyze the impact of the adoption of ISO 14001 and ISO 9001 on Portuguese companies' performance. This empirical study aims to show all investors, managers, regulators and civil society itself the long path that still needs to be taken toward sustainability.

This paper aims to analyze the corporate governance and corporate social responsibility (CSR) determinants of the Portuguese listed companies’ performance, considering a different point of view by managers, shareholders and other external stakeholders and investors.

To achieve this aim, the authors have used a sample of 34 nonfinancial listed companies in Euronext Lisbon between 2015 and 2020. The authors use the panel data methodology to test the hypotheses formulated according to the literature review, specifically the generalized method of moments (GMM) system estimation model proposed by Arellano and Bond (1991).

The main results point out that the determinants of the corporate performance vary depending on the dependent variable considered. From the managers’ perspective, the existence of an audit committee and expenses with the environment increase costs and reduce results, negatively influencing corporate performance, but the company’s maturity adds synergies in resource management and positively influences performance. Shareholders consider that gender diversity and board independence positively influence performance, whereas, for external stakeholders and long-term investors, gender diversity and the social responsibility committee harm the performance of Portuguese companies. However, environmental and social expenditures have a positive effect, showing that the market’s perception is that, in the long run, it is essential to eradicate poverty and protect the environment.

To the best of the authors’ knowledge, this study is the first one to analyze corporate governance and CSR determinants on the performance of listed Portuguese companies. This study shows that in a small banking-oriented country, there is still a long way to go in terms of increasing social responsibility and governance among different stakeholders. It is essential to promote actions that lead to effective governance and awareness of social responsibility.

The purpose of this paper is to analyse the impact of political connections and gender diversity on the performance of Iberian companies as a singular market and considering Portugal and Spain separately.

The authors used panel data methodology, specifically GMM system estimation model by Arellano and Bond (1991) for the period from 2015 to 2020.

Results show that the performance of listed Iberian companies is influenced by political connections, by gender diversity and that gender diversity has a mitigating effect on the effects of political connections in each country. The mitigating effect of women is evident in both Portugal and Spain, as they are more cautious and principled, which is valued by short-term investors interested in an immediate investment. However, considering the Iberian Peninsula as a whole, the results indicate that – in the long term – women's political relationships can benefit performance through a better reputation and image, which can lead to better social and economic results in the long term.

To the best of the authors’ knowledge, this paper is original and covers an important gap in the literature when considering political connections and women's impact on these connections as determinants of the performance of Iberian companies.

As high-tech industries are the main responsible for research and development (R&D), the purpose of this paper is to investigate some of the possible determinants of R&D investment in this type of industry.

The analysis is based on a sample of European high-tech industries represented both by countries of civil law origin and common law origin. The authors used data from 155 high-tech firms in the period between 2011 and 2016. The sample was collected from Amadeus database. The panel data methodology was used to test the dependence of R&D expenses ratio according to different variables. Specifically, the authors have used the generalized method of moments (GMM) estimation method.

The results point out that there are differences in the explanation of the R&D ratio depending on whether the authors are dealing with countries of civil legal origin or common legal origin. The evidence also suggests that the intangible assets, contrary to the expect result, have a negative influence on R&D. Probably in this recovery time, as de global financial crisis and the sovereign debt crisis for Eurozone countries, the high-tech firms are using their intangible assets to create value and not for more investments in R&D. Companies are not renewing their asset stocks.

As high-tech companies are traditionally rich in R&D, this research can contribute with additional pieces to the knowledge of the factors that contribute to this. Thereby, this study may be interesting for managers, investors and civil society. This study adds value as it is unique in addressing this topic on this new dimension, with respect to the sample and indicators presented.

Como las industrias de alta tecnología son las principales responsables por la I + D, proponemos investigar algunos de los posibles determinantes de la inversión en I + D en este tipo de industria.

Nuestro análisis se basa en una muestra de indústrias europeas de alta tecnología representadas tanto por países de origen civil como por derecho consuetudinario. Utilizamos datos de 155 empresas de alta tecnología en el período comprendido entre 2011 y 2016. Nuestra muestra se recopiló de la base de datos Amadeus. La metodología Panel Data se utilizó para evaluar la dependencia del índice de gastos de I + D de acuerdo con diferentes variables. Específicamente, hemos utilizado el método de estimación del Método Generalizado de Momentos (GMM).

Nuestros resultados señalan que existen diferencias en la explicación de la relación de I + D dependiendo de si estamos tratando con países de origen legal civil u origen legal común. Nuestra evidencia también sugiere que los activos intangibles, al contrario del resultado esperado, tienen una influencia negativa en la I + D. Probablemente en este tiempo de recuperación económica, desde la crisis financiera mundial y la crisis de la deuda soberana para los países de la zona euro, las empresas de alta tecnología están utilizando sus activos intangibles para crear valor y no para más inversiones en I + D. Las empresas no renuevan sus activos.

Dado que las empresas de alta tecnología son tradicionalmente ricas en I + D, esta investigación puede contribuir con piezas adicionales al conocimiento de los factores que contribuyen a esto. Por lo tanto, este artículo puede ser interesante para gerentes, inversores y la sociedad civil. Este artículo agrega valor, ya que es único al abordar este tema en esta nueva dimensión, con respecto a la muestra y los indicadores presentados.

Como as indústrias de alta tecnologia são as principais responsáveis pela investigação e desenvolvimento, neste trabalho propomos investigar alguns dos possíveis determinantes da I&D nesse tipo de indústria.

A Nossa análise é baseada em uma amostra de indústrias europeias de alta tecnologia representadas por países de origem do direito civil e de direito comum. Foram utilizados dados de 155 empresas de alta tecnologia no período compreendido entre 2011 e 2016. Os dados foram recolhidos da base de dados Amadeus. Foi usada a metodologia de Dados em Painel para testar a dependência entre as despesas de I&D e as diferentes variáveis explicativas. Especificamente, usamos o método de estimação Método generalizado de momentos (GMM).

Os nossos resultados apontam que existem diferenças na explicação do índice de I&D, dependendo de estarmos lidando com países de origem legal civil ou de origem legal comum. As evidências também sugerem que os ativos intangíveis, ao contrário do resultado esperado, influenciam negativamente a I&D. Provavelmente neste período de recuperação económica, desde a crise financeira global e a crise da dívida soberana dos países da zona do euro, as empresas de alta tecnologia estão a usar os seus ativos intangíveis para criar valor e não para mais investimentos em I&D. As empresas não estão a renovar os seus ativos.

Como as empresas de alta tecnologia são tradicionalmente ricas em I&D, este trabalho pode contribuir com peças adicionais para o conhecimento dos fatores que contribuem para esse facto. Assim, este artigo pode ser interessante para gestores, investidores e sociedade civil. Trata-se de uma investigação que agrega valor, pois é único ao abordar este tópico nesta nova dimensão, com relação à amostra e às variáveis apresentadas.

The purpose of this study is to examine the determinants of the level of indebtedness in the health sector in Portugal, taking into account the effects of the COVID-19 pandemic. At the same time, an attempt is made to understand whether the effect of a pandemic crisis is similar to that of a financial crisis.

To achieve this aim, two subperiods were analyzed: a global period between 2011 and 2020 that includes the pandemic crisis and the period between 2011 and 2014, designated as the financial assistance period by the “Troika” in Portugal. For a sample of 514 companies belonging to the NACE code: 86100 – activities of the health sector with hospitalization, the panel data methodology was applied, specifically, the generalized method of moments system proposed by Arellano and Bover (1995) and Blundell and Bond (1998).

The results of the study are in line with the Pecking-order explanatory theory, demonstrating that companies in this sector follow a financing hierarchy, preferentially resorting to internally generated funds and external debt. Additionally, the results reveal that the capital structure of companies has changed due to the COVID-19 pandemic. As for the period of financial assistance, there are no major differences in evidence when the total debt ratio is considered. The results suggest different impacts when it comes to a bear market period caused by a health crisis or a period of growing economic slowdowns.

As far as we know, this is the first study that analyses the debt levels in the context of the health sector in a country with a financial system based on the bank sector, using short- and long-term debt ratios, taking into account the particularities of two different moments considered to be bear market that may eventually be useful for comparison with other bear market moments in other macroeconomic environments.

El objetivo principal de este estudio es examinar los determinantes del nivel de endeudamiento en el sector de la salud en Portugal, teniendo en cuenta los efectos de la pandemia de COVID-19. Al mismo tiempo, se intenta comprender si el efecto de una crisis pandémica es similar al de una crisis financiera.

Para lograr este objetivo, se analizaron dos subperíodos: un período global entre 2011 y 2020 que incluye la crisis pandémica y el período entre 2011 y 2014, designado como el período de asistencia financiera por la “Troika” en Portugal. Para una muestra de 514 empresas pertenecientes al código NACE: 86100 – actividades del sector de la salud con hospitalización, se aplicó la metodología de datos de panel, específicamente, el método generalizado de momentos (GMM)-sistema propuesto por Arellano y Bover (1995) y Blundell y Bond (1998).

Los resultados del estudio están en línea con la teoría explicativa del “Pecking-order”, demostrando que las empresas en este sector siguen una jerarquía de financiamiento, recurriendo preferentemente a fondos generados internamente y deuda externa. Además, los resultados revelan que la estructura de capital de las empresas ha cambiado debido a la pandemia de COVID-19. En cuanto al período de asistencia financiera, no hay diferencias significativas en la evidencia cuando se considera la proporción total de deuda. Los resultados sugieren impactos diferentes cuando se trata de un período de mercado bajista causado por una crisis de salud o un período de crecimiento económico más lento.

Hasta donde sabemos, este es el primer estudio que analiza los niveles de deuda en el contexto del sector de la salud en un país con un sistema financiero basado en el sector bancario, utilizando ratios de deuda a corto y largo plazo, teniendo en cuenta las particularidades de dos momentos diferentes considerados como momentos de mercado bajista que eventualmente pueden ser útiles para comparar con otros momentos de mercado bajista en otros entornos macroeconómicos.

O principal objetivo deste estudo é examinar os determinantes do nível de endividamento no setor de saúde em Portugal, levando em consideração os efeitos da pandemia de COVID-19. Ao mesmo tempo, tenta-se compreender se o efeito de uma crise pandêmica é semelhante ao de uma crise financeira.

Para atingir esse objetivo, foram analisados dois subperíodos: um período global entre 2011 e 2020, que inclui a crise pandêmica, e o período entre 2011 e 2014, designado como o período de assistência financeira pela “Troika” em Portugal. Para uma amostra de 514 empresas pertencentes ao código NACE: 86100 – atividades do setor de saúde com hospitalização, foi aplicada a metodologia de dados em painel, especificamente o método generalizado de momentos (GMM)-sistema proposto por Arellano e Bover (1995) e Blundell e Bond (1998).

Os resultados do estudo estão de acordo com a teoria explicativa da ordem de preferência (“Pecking-order”), demonstrando que as empresas neste setor seguem uma hierarquia de financiamento, recorrendo preferencialmente a fundos gerados internamente e dívida externa. Além disso, os resultados revelam que a estrutura de capital das empresas mudou devido à pandemia de COVID-19. No que diz respeito ao período de assistência financeira, não há diferenças significativas na evidência quando se considera a proporção total de dívida. Os resultados sugerem impactos diferentes quando se trata de um período de mercado em baixa causado por uma crise de saúde ou um período de desaceleração econômica.

Até onde sabemos, este é o primeiro estudo que analisa os níveis de dívida no contexto do setor de saúde em um país com um sistema financeiro baseado no setor bancário, utilizando índices de dívida de curto e longo prazo, levando em consideração as particularidades de dois momentos diferentes considerados como momentos de mercado em baixa que eventualmente podem ser úteis para comparação com outros momentos de mercado em baixa em outros ambientes macroeconômicos.
