title: Complexity and corporate governance: an analysis of companies listed on the BM&FBOVESPA

description: ABSTRACT In light of the need to develop mechanisms of control, protection, and transparency regarding the relationships between principal and agent, and with the aim of eliminating or reducing the agency problem, corporate governance has emerged. Based on Agency Theory, separation of ownership and control of activities derives from the complexity of organizations. In this context, this study aims to analyze the relationship between dimensions of complexity and corporate governance in companies listed on the São Paulo Stock, Commodities, and Futures Exchange (BM&FBOVESPA), in which contingency factors might influence organizational characteristics. The investigation gathers data from a sample of 162 companies listed on the BM&FBOVESPA. The following statistical tests were used in the data analysis: Factor Analysis, Multiple Linear Regression, Correspondence Analysis, and Correlation Analysis. For measuring complexity, contingency variables such as age, size, diversification, and internationalization were adopted; and, to assess corporate governance, a representative index of the adoption of good governance practices was used. The results show that organizational complexity is explained by the size and diversification variables, whereas operational complexity is explained by the size, diversification, and internationalization variables. It was observed that in the two dimensions of complexity - organizational and operational - corporate governance was influenced by the diversification, internationalization, and age variables, with the latter involving an inverse relationship. It is concluded that companies displaying more complexity, in its two dimensions, record a higher level of corporate governance, which confirms the research hypothesis.

title: Predictive power of Brazilian equity fund performance using R2 as a measure of selectivity

description: ABSTRACT This paper aimed to investigate the impact of levels of selectivity on the performance of equity funds using a methodology applied for the first time ever (as far as we know) in the Brazilian market. As an indicator of the activity level of a fund, we proposed the coefficient of determination (R2) of the regression of its returns over market returns. In total, 867 funds were analyzed in the period between November 2004 and October 2014. The hypothesis tested is that more selective funds perform better to compensate for their higher operating costs. This hypothesis was confirmed in the Brazilian market. Dynamic equally-weighted portfolios of funds were simulated, according to their past R2 and alphas, with monthly rebalancing and 12-month moving windows. The portfolio of the most selective funds had a Sharpe ratio of 0.0494, on a monthly basis, while the portfolio of the least selective funds had a Sharpe ratio of -0.0314. Performance was also higher in evaluations involving excess returns, Jensen’s alpha, and accumulated returns, as well as when compared to randomly selected portfolios. Moreover, past performance (as measured by Jensen’s alpha) was also a predictor of future performance. Particularly, the portfolio composed by funds with a higher past alpha and lower past R2 presented a Sharpe ratio of 0.1483 and a Jensen’s alpha of 0.87% (significant at 1%), while the one composed of funds with a lower past alpha and lower activity level presented a Sharpe ratio of -0.0673 and an alpha of -0.32% (also significant at 1%).

title: Investor relations and information asymmetry

description: ABSTRACT Companies invest significant volumes of resources in investor relations (IR) departments. The professionals working in the IR department are responsible for communication between the company and the market, so that the information generated is widely disseminated and understood by investors. In this context, this research aims to investigate whether there is evidence that the IR activity decreases information asymmetry between the company and the market. Specifically, we evaluate the hypothesis that Brazilian companies with IR websites classified as more informative have a reduced bid-ask spread (proxy for asymmetry). Therefore, this paper classifies the informative content from IR websites of Brazilian companies for the years 2013 and 2014 and relates the outcomes obtained with information asymmetry metrics. Initially, the estimation considers the pooled ordinary least squares (POLS) model and, at a second moment, in order to mitigate potential endogeneity problems, the pooled two-stage least squares (2SLS) model is used. The results indicate that more informative IR websites are able to decrease the bid-ask spread of Brazilian listed companies. This finding strongly encourages companies to provide information to stakeholders on well-structured IR websites of their own.

title: Satisfaction among accounting professors in Brazil

description: ABSTRACT The aim of this study was to identify the prevalence of satisfaction among accounting professors in Brazil throughout their careers. The research is classified as descriptive and used a quantitative approach to data analysis. 641 valid responses were obtained from professors from all regions of Brazil. The results show that a feeling of satisfaction prevails among accounting course professors, as most of them “like the profession” and, in general, "are satisfied with it”. It was found that levels of satisfaction are higher among individuals with more experience, in that in their first years in the job (one to three years), professors have lower satisfaction rates; the highest levels of satisfaction are found in the final stage (over 35 years). The main factor that influences satisfaction is personal fulfillment (teaching work and relationship with students). It was also possible to identify that positive feelings about teaching predominate (67.3%) compared to negative ones (32.7%). These results show the need for greater attention to be paid in the early years of the career in order to avoid a "reality clash". They also show the need for other studies to investigate how the phases in the life cycle of accounting professors are characterized.

title: Challenges with the public policy of measuring assets to set tariffs in the electricity sector: should someone benefit and someone be sacrificed?

description: ABSTRACT This paper contributes by encouraging discussions about the public policy of setting tariffs for public services based on the value of the investment made by the providers of these services. The purpose of this study was, in an unprecedented way and by combining theories of equity valuation and finance, to identify the asset valuation method that can lead to a fair value and balance between an affordable price for the consumer and an adequate return on investment for the concessionaires. The value assigned to these assets affects the tariff in two ways: (i) via depreciation/amortization, which affects the cost of service; (ii) via the return on investment, which is the portion that corresponds to the investor’s profit. We analyzed the Brazilian electricity sector, in which the rates set by the Brazilian Electricity Regulatory Agency (ANEEL) currently use the new replacement value (NRV) approach. We carried out empirical tests using data available on the ANEEL website from the second cycle periodic tariff review and information obtained in financial statements from 1995 onwards. The analysis included the NVR and restated historical cost (RHC) methods, the latter being updated by the extended consumer price index (IPCA). After the descriptive and statistical analyses, we used the test of means to verify the differences between the variables in terms of NRV vs. RHC. The first conclusion was the absence of a significant difference between the NRV and RHC methods; that is, on average, the replacement price showed no significant difference to what would be the pure and simple restatement of assets. But this was found to hide something relevant, the fact that this average is derived from two main groups: that of the consumers who are paying more for energy services than they should, which constitutes a visible benefit to investors and loss for these consumers, and that of the consumers who are paying less than they should, which benefits them but harms investors.

title: IFRS, synchronicity, and financial crisis: the dynamics of accounting information for the Brazilian capital market

description: ABSTRACT This study aims is to investigate the synchronicity levels of shares traded on the spot market of the São Paulo Stock, Commodities , and Futures Exchange (BM&FBOVESPA) in relation to the accounting convergence process towards International Financial Reporting Standards (IFRS) in Brazil. The term synchronicity refers to the amount that company-specific information and market information are reflected in stock prices. The more share prices reflect company-specific information rather than market information, the greater the informational content of these prices will be in terms of representing the economic value of a particular company. For this investigation, information on companies and shares from 2005 to 2015 was collected, excluding the financial sector. The data were analyzed using cross-sectional and panel regressions. The results indicate a reduction in the synchronicity levels of stocks in the period of full adoption of IFRS in Brazil from 2010 onwards. From 2008 to 2009, which includes the partial adoption of IFRS in Brazil, statistically significant results were not found for the synchronicity levels of shares. However, for times of financial crisis, evidence was found of a reduction in the relevance of accounting information even with the adoption of international accounting standards. The results obtained for the Brazilian context do not support the idea that the adoption of IFRS necessarily causes an increase in the informational content of financial statements and that relevant information is consequently reflected in stock prices.

title: The relationship between the performance and legal form of microfinance institutions

description: ABSTRACT This paper investigates the relationship between the legal forms adopted by microfinance institutions (MFIs) and their performance within three scopes: financial performance, social performance, and efficiency in resource allocation. The MFIs studied are classified into four groups: banks, non-governmental organizations, cooperatives, and a fourth group formed of for-profit institutions not characterized as banks, made up of non-bank financial institutions (NBFIs) and rural banks. The data used are annual and cover the six years from 2007 to 2012. The quantitative regression model with panel data was used together with dummy variables to compare between the four groups of legal forms, except for the group made up of NBFIs and rural banks, which was not represented by any dummy variable. 304 MFIs from 59 countries made up the sample. In the study it was observed that larger MFIs have higher profits, higher returns, and higher operational self-sufficiency rates than smaller MFIs, indicating that MFI growth could enable consolidation in the microfinance market. The results also indicate that for smaller MFIs the way to consolidate and improve the indicators could be through assimilating or merging with other MFIs. It was also noted that non-bank financial institutions and rural banks are able to serve more customers and that cooperatives provide smaller loans, causing a bigger social impact, and that they obtain higher returns and profits. The results indicate that these legal forms may be the most appropriate for the microfinance market.
