This study aims to examine the listing of firms at the highest corporate governance level of the Brazilian stock exchange (B3) as a means of legitimation and its relationship with risk and return on investment.

This paper analyzes 205 companies from 2010 to 2019, in which firms listed at the Novo Mercado level were compared with groups composed of other firms traded on B3.

The main results demonstrate that a listing at the supposedly higher level of corporate governance in Brazil does not indicate lower risk, a higher return or even a better risk-return ratio.

The findings are restricted to this sample, representing the association identified between the analyzed phenomena and not a cause-effect relationship.

The highest level of corporate governance in Brazil brings together firms that present a higher risk (at least systematic) and lower returns (at least financial) because they seek to legitimize themselves in the market as firms committed to better management practices.

These findings are useful to investors, the stock exchange, regulatory agents and the companies themselves to reflect on the purpose and usefulness of different levels of corporate governance in Brazil.

This study differs from the others that relate corporate governance to risk or return because it does not deal individually with corporate governance practices, but rather the phenomenon that is listed in a special governance level, created by the stock exchange, serving as a kind of seal legitimation.

This study identified how investor sentiment on Twitter is associated with Brazilian stock market return and trading volume.

The study analyzes 314,864 tweets between January 1, 2017, to December 31, 2018, collected with the Tweepy library. The companies’ financial data were obtained from Refinitiv Eikon. Using the netnographic method, a Twitter Investor Sentiment Index (ISI) was constructed based on terms associated with the stocks. This Twitter sentiment was attributed through machine learning using the Google Cloud Natural Language API. The associations between Twitter sentiment and market performance were performed using quantile regressions and vector auto-regression (VAR) models, because the variables of interest are heterogeneous and non-normal, even as relationships can be dynamic.

In the contemporary period, the ISI is positively correlated with stock market returns, but negatively correlated with trading volume. The autoregressive analysis did not confirm the expectation of a dynamic relationship between sentiment and market variables. The quantile analysis showed that the ISI explains the stock market return, however, only at times of lower returns. It is possible to state that this effect is due to the informational content of the tweets (sentiment), and not to the volume of tweets.

The study presents unprecedented evidence for the Brazilian market that investor sentiment can be identified on Twitter, and that this sentiment can be useful for the formation of an investment strategy, especially in times of lower returns. These findings are original and relevant to market agents, such as investors, managers and regulators, as they can be used to obtain abnormal returns.

Corporate social responsibility (CSR) and corporate sustainability have gained prominence in the major capital markets. In Brazil, the São Paulo Stock Exchange (BM&FBovespa) has created the Corporate Sustainability Index (ISE) and the Carbon Efficient Index (ICO2), responsible for indicating the performance of sustainable companies. Therefore, this study proposes to examine and compare the stock returns of the sustainability index member companies with the returns of companies out of these indexes. In this methodology we selected the two principal negotiability indexes of that market (IBOV and IBrX50), which are indexes that meet the most traded stocks of BM&FBovespa, and calculated the average daily returns of the four indexes in order to make performance comparisons over the period 2005–2014, based on nonparametric statistical tests. Our findings indicate that the average returns of sustainability indexes were higher, but these differences were not statistically significant, confirming previous evidence. Additionally, by means of a cointegration test, we found that the indexes are cointegrated in the long term. These findings are limited to the analyzed emerging market and are also subject to the limitations of the estimated models. Thus, we can infer that presence in the sustainability indexes does not indicate statistically significant higher returns, which means that companies with sustainable practices in Brazil are not only concerned with economic performance, but also with social, cultural, and environmental issues. The main findings are aligned with the concept of triple bottom line, even in the case of an emerging market.

Investors label high (low) book-to-market (B/M) firms as value (growth) companies. The conventional wisdom supports that growth stocks grow faster than the value ones, creating greater shareholder value. The Purpose of this paper is to analyze how stocks of growth and value companies create value for their shareholders in Brazil, compared to the USA market. For this, the authors analyze three dimensions of return.

First, the authors perform portfolios to analyze the growth rates of shareholders’ return. Then, the authors perform regressions to study the explanatory power of the B/M in growth. The data come from Thomson Reuters Eikon database and the Brazilian Institute of Geography and Statistics. The authors select all non-financial firms with available data from 1997 to 2017.

The profitability of growth firms is higher than the value ones, in almost every year after the portfolios’ formation, with little variation. Contrary to the findings for the US market, growth companies in Brazil show higher dividend growth than value companies.

It is possible that the database does not contain complete and entirely reliable accounting data, which may partially affect the results.

The findings contradict those exposed in the USA. The implications are the inverse of the US study: the duration-based explanation could be a vital factor for the value premium in the Brazilian stock market. Also, the findings support the standard valuation techniques and help the growth rates estimation in the valuation process (top-down approach).

This study is the first to compare the profitability and dividend growth of growth/value stocks in the Brazilian market. Overall, growth stocks have considerable profitability, and dividend growth compared to value stocks.

We analyze how Brazilian Black Movement organizations and banks deployed different mechanisms like cooperation, cooptation, and confrontation that generated affirmative action initiatives in the banking sector at the beginning of this century. Black movement organizations triggered an institutional change by connecting fields and exploring a constellation of strategies. However, Brazilian banks adopted defensive strategies aiming to accommodate their interests. We find that only piecemeal change occurred, as the field’s structures – resource distribution and power – remained unscratched. We conclude by noting how the success of social movement strategies can depend upon the framing and sense-giving work that social movements conduct in their continuous jockeying activity toward incumbents.

The domain of digital service not only includes digital service products made available for purchase but also the provision of digital customer service, such as customers seeking support on brands' social media channels. This type of digital customer service introduces new challenges not found in offline service recovery situations. This research highlights one such occurrence by investigating customer-to-customer (C2C) interactions during digital service recovery. In particular, dysfunctional dialog, such as online incivility (e.g. rude and insulting comments), directed at a complainant by a fellow customer is investigated.

Survey data from an online panel are utilized to test the hypothesized relationships between dysfunctional customer behavior (i.e. online incivility), C2C interactional justice, customer perceived service climate and three forms of experiential value using partial least squares structural equation modeling (PLS-SEM).

The results show that customer perceptions of the firm's service climate are negatively affected by online incivility but only when such incivility produces C2C injustice. This outcome is notable due to the strong relationship found between customer perceived service climate and the following three forms of online experiential value: sociability, hedonic and pragmatic value. Thus, a weakened service climate subsequently leads to weakened experiential value for complainants.

The theoretical implications of two nascent constructs, C2C interactional justice and customer perceived service climate, are further developed with reference to digital customer service situations. In particular, given that prior research has focused on customer perceptions of service climate in core consumption situations of enjoyable face-to-face service experiences, it has only considered optimal or extremely positive service climate assessments in non-digital contexts. This study expands the understanding of the customer perceived service climate construct by examining the implications of a sub-optimal service climate in a digital customer service situation of an unenjoyable service experience. The limitations include a small sample size, the use of hypothetical scenarios and a failure situation limited to a single industry.

Managers who oversee social media channels or online communities must be prepared to act upon C2C online incivility. Deeming such communications as innocent online chatter not worthy of company intervention is a mistake, as the results of this study show that such inaction may lead to negative customer perceptions of the digital service environment and harm the customer experience.

This work develops a greater understanding of the importance of C2C interactional justice and customer perceived service climate in online customer service situations that prior research has yet to establish. In particular, previous studies have not investigated the negative effects of a situation that produces sub-optimal customer perceptions of a service climate.

Brand management has traditionally enlisted visual branding elements, including the brand’s graphic logo, to distinguish and communicate the personality of the brand. However, as healthcare organizations work to shape how consumers perceive their brand, organizations are also enhancing their brand identity with sound and music by creating a sonic brand. This research paper aims to examine how sonic brands influence consumer emotional reactions and trust in a healthcare provider. It also explores how sonic brands can differentially affect consumers, depending on their level of engagement in their physical and mental health.

Two experimental studies were conducted that tested the use of a sonic logo for healthcare providers in consumption contexts that might elicit negative emotions, cancer care and mental health care.

The results suggest that the presence of a sonic logo helped to alleviate negative emotions as well as engender trust in the provider. Findings also revealed that for consumers who are less engaged in their health, a sonic logo served as a peripheral cue by enhancing perceptions of competence and empathy for the healthcare provider.

Findings from this research provide insight into how sonic brands can increase the effectiveness of branded healthcare communications.

Research suggests there are at least three challenges to Black male interest and success in STEM careers: increasing access to STEM resources and curriculum, increasing Black and male inclusiveness in STEM initiatives, and increasing cultural and technical competency in STEM fields. African American schools typically do not have equitable STEM resources or instruction. In addition, there is limited research on supporting Black males' success in STEM in the culturally responsive computing (CRC) literature. Most STEM initiatives prioritize increasing the number of girls in STEM fields. STEM field employers are not active recruiters of Black male hires and have little experience with diversity and cultural inclusiveness. Research also suggests that Black students may not be interested working in White corporate America that undervalues their unique cultural perspectives and are more concerned with schooling that improves their communities. This chapter utilized CRC as a lens to examine the complexity of engaging Black males in STEM. As a result, the authors suggest adopting an equity ethic to help teachers help Black males connect themselves and their communities to STEM technology by utilizing smartphones and smartphone technology to engage Black males who may not have access to computers. We end with an example of CRC called barbershop computing, which combines computing, engineering, and innovation as a method to attract and retain Black males in STEM classes and help them persist in STEM careers.
