Purpose: This paper aims to examine the relationship between board of directors’ characteristics and performance in family businesses. It offers evidence to the question of whether a family firm (FF) differs from a non-family firm and looks at the possibility of asymmetrical effects between periods of stability and economic adversity. Design/methodology/approach: A panel data approach was applied to a sample of Portuguese firms listed the on Euronext Lisbon exchange between 2002 and 2013. Findings: The results show that FFs are likely to have a lower proportion of independent members and higher gender diversity on their boards than non-family firms. FF performance is positively related to ownership concentration and gender diversity. There are performance premiums for family businesses, which have more gender diversity than their counterparts. These effects also depend on whether the economy is in recession. The evidence suggests that the presence of women on the board and the leverage and size of the FFs have a more significant impact on the performance in periods of economic adversity. Research limitations/implications: One limitation of this study is the small size of the sample as it was drawn from the Euronext Lisbon exchange, a small stock exchange market. Originality/value: This study provides input into the academic discussion on corporate governance and FF, an area which is in need of research. In addition, the authors examine this issue in conjunction with generalised economic adversity, focusing on the possible asymmetrical effects that the nature of the board of directors may have on performance in periods of stability and those of economic adversity. The role of board of directors is crucial to the understanding of corporate behaviour and the setting of the policy that regulates corporate activities.

Purpose: The purpose of this paper is to analyse the determinants of Portuguese firms’ performance.Design/methodology/approach: To achieve this aim, the authors used data from 37 non-financial firms in the period between 2010 and 2015. Three dependent variables were tested and the estimation of the model using the Generalised Method of Moments shows that internal, external and institutional factors are important to explain the performance of firms listed in Euronext Lisbon.Findings: The determinants of firm performance vary depending on the variable used to measure the performance. Specifically, the results show that when the authors use a market variable of performance, the firm-specific variables are not so important to explain performance. The macroeconomic factors, including the investor’s sentiment and insider ownership, more effectively explain the firm’s performance. The evidence suggests that the determinants of firm performance change according to the way in which different stakeholders appreciate firm performance.Originality/value: The main contribution of such approach is to show that internal and external factors influence performance measures in distinct ways, thus helping managers who are expected to make decisions according to the investors’ expectations. It provides initial guidelines for policy makers to understand how to improve the performance of their firms using firm-specific factors. Additionally, this work also demonstrates that the firm’s characteristics, macroeconomics and governance factors could affect the Portuguese firms’ performance, conveying a valuable contribution for investors.

Purpose: The investigation of the relationship between gender diversity and corporate risk-taking is a recent stream of research. In this study, the authors propose an answer to the following main question: What do the authors know about gender effects in corporate risk-taking and how should we proceed?Design/methodology/approach: In order to ensure the quality and the objectiveness of the literature review, the authors selected articles published in journals that are simultaneously ranked by the Chartered Association of Business Schools (ABS, 2018) and by the Journal Citation Reports (JCR, 2018), focused on the Board of Directors (BoD) and Top Management Teams (TMT).Findings: The literature review reveals that women's presence on the BoD and TMT impacts corporate risk-taking in different ways. Based on the analysis, it is possible to organize the extant findings in two major categories, according to gender measures, firm type and country of origin: (1) universal effects – women decrease firms' litigation risk, failure risk and operational risk while they have no significant effect on insolvency risk and; (2) contingent effects – women have contingent effects on financial risk, manipulation risk, total risk, idiosyncratic risk and systematic risk.Originality/value: Covering several different research fields, this study provides a comprehensive review concerning what the authors know regarding the effects of the BoD and TMT gender diversity in corporate risk-taking. The authors present a model summarizing empirical findings and propose a number of avenues for future research.

This work studies herding behaviour in a small European market, by analysing the stocks that constituted the Portuguese stock PSI-20 index, for the period between 2003 and 2011. The two different approaches used to measure herding intensity led to different results, suggesting that measurements of the herding phenomenon are sensitive to the method used. Consequently, there is a need for further research into the methodology used to test this phenomenon. Additionally, the study analyses the relationship between herd behaviour and investor sentiment, an area that has been little explored. In applying causality tests to the impact of sentiment on herd behaviour, only weak evidence is found that sentiment influences herding
