Set Up

We set up a model to study the voluntary disclosure of information by insiders of publicly traded companies. We consider a trading framework as in [14] with many assets and one insider per asset. There is one discretionary liquidity trader who can allocate his trades across the different assets and many noise traders who trade with equal intensity in all assets. Before trade begins, insiders can disclose information in order to attract the discretionary liquidity trades. We show that if the level of noise trading is above a certain threshold, then there is an equilibrium where all insiders do not disclose any information. Below this threshold, equilibria are such that some information is always revealed by insiders. We also find that the greater the number of assets, the smaller the intensity of noise trading must be in order to induce insiders to disclose some information, and we find that insiders reveal all their information when the intensity of noise trading approaches zero.

ABSTRACT This article aims to verify what the influence is of different disclosure activities on the concentration of more sophisticated investors in Brazilian companies. The study fills a gap regarding the influence that disclosure activities can have on the concentration of sophisticated investors in Brazilian firms, considering that this may occur due to their ability to maximize the usefulness of the information disclosed and the return on investments, with a reduction in the cost of allocated funds. This subject is relevant because it verifies not the clientless effect of disclosure, presented by the only study previously developed on the subject in the United States (Kalay, 2015), but rather the influence that disclosure activities (earnings forecasts, market communications, and investor relations [IR]) have on the most sophisticated investors’ decisions to allocate funds in companies in the Brazilian market. As an impact on the area, it was noted that those companies that release market communications attract the investment of funds and the concentration of sophisticated investors much more than those that present better IR and release profit forecasts. We studied 89 publicly-traded companies whose reference forms were published in the period from 2011 to 2016. The number of institutional investors disclosed in the reference forms was used as a proxy to categorize them as more sophisticated. The different disclosure activities were represented by the disclosure of profit forecasts, the number of market communications, and the best IR. The best IR proxy was categorized using the companies awarded by IR Magazine Brazil that presented the best IR in the study period. The results of this study show that the most sophisticated investors concentrated in companies with better IR, in those that do not disclose profit forecasts, and in companies with a greater number of disclosed market communications. The disclosure of market communications is the disclosure activity that most influences the concentration of sophisticated investors in Brazilian companies that use more voluntary disclosure than discretionary disclosure to allocate their funds.

Longitudinal Dataset

This article studies the gender composition of corporate boards of Russian companies, including its relation to company performance. The analysis is based on a unique longitudinal dataset of virtually all Russian companies whose shares were traded on the stock market in 1998-2014. It shows a relatively small representation of women, just 12% of all the seats, while about 40% of the companies did not have any female director. At the same time, both the share of companies that appoint female directors and the share of female directors on boards show a clear upward trend. The econometric analysis suggests a positive link between the presence of female directors on boards and company performance, especially when firms appoint several, rather than one, female directors.

According to many business publications, firms that experience information security breaches suffer substantial reputational penalties. This paper examines incidents in which confidential information, for a firms customers or employees, is stolen from or lost by publicly traded companies. Firms that experience such breaches suffer statistically significant losses in the market value of their equity. On the whole, the data indicate that these losses are of similar magnitudes to the direct costs. Thus, direct costs, and not reputational penalties, are the primary deterrents to information security breaches. Contrary to many published assertions, on average, firms that lose customer information do not suffer reputational penalties. However, when firms lose employee information, we find significant reputational penalties.

Free Cash Flows

This research analyzes the relationship between free cash flows (FCFs) and the different levels of Corporate Governance present in the Brazilian stock market. To this end, the sample was composed of 212 Brazilian publicly traded companies listed on Brasil, Bolsa, Balcão [B]³, in the period from 2010 to 2018. The methodology consisted of estimating a regression for panel data, using the random effects model, estimating by generalized least square (GLS) and assuming adjustments for autocorrelation and robust standard errors for heteroscedasticity. The results found, for the sample studied, suggest that Corporate Governance levels are positively related to the FCFs. In synergy, when compared to the Traditional level of [B]³, companies listed on the Novo Mercado and Level 2 levels tend to present higher FCF values. In addition, the larger the size of the companies and the higher their return on equity, the higher their FCFs tend to be, just as companies in stages of maturity tend to present lower FCF values. The relevance of this research is based on analyzing, in a stock market subject to imperfections, factors that may affect decisions about the level of cash maintenance of companies, more specifically by evaluating how Corporate Governance mechanisms relate to the theory of FCFs, in a context of potential conflict of interest.

Security Incidents

Data security incidents are continually increasing; hackers, governments, and other actors increasingly attempt to gain unauthorized access to confidential data. Information Systems (IS) users are becoming more vulnerable to the risks of data breaches. Many stakeholders perceive cybersecurity incidents as indicators of firms' operational and technological internal deficiencies. Previous research has revealed that investors react negatively to data breaches, yet little is known about investors' reactions to material data security incidents. Using a sample of 232 data security incidents for 132 publicly traded companies in the United States, we applied an event study methodology to discern investors' reactions to material versus immaterial incidents. We also use multivariate regression and time-to-event analysis to examine what determines the degree of investors' reactions, considering several intervals around the event day. Our results show that investors perceive material data security incidents as a deficiency of breached companies in comparison to immaterial incidents.
