title: Financial Illiteracy and customer credit history

description: Abstract Purpose: We study how financial illiteracy affects the probability of a derogatory mark on the customer’s credit history. Design/methodology/approach: We use the National Survey on Financial Inclusion in Brazil together with information on financial instrument usage and spending provided by the head of the household. To estimate the impact of financial illiteracy on the probability of a derogatory mark we use a logistic model to compute the odds ratio. Findings: Our main result is that financially illiterate individuals have between 57% and 143% more chance of having a derogatory mark. We find that age, income, expenses, and retirement positively affect the probability of a derogatory mark, while marriage has a negative impact. Gender does not have any impact over the probability of derogatory mark. Originality/value: The study uses a new proxy for financial illiteracy and correlates it to the investment and debt decisions of a family using a unique dataset.

title: Elections and CEO successions in Brazilian state-owned companies

description: Abstract Purpose: To study the impacts of elections and succession processes on SOE stocks. Design/methodology/approach: Through events studies we longitudinally investigate the impacts of political events (elections) and of succession processes on SOE stocks over more than 20 years. We also document changes in management, showing that SOEs face greater turnover in management than their private peers. Stock quotations were obtained from Economática and company and executive data were retrieved from the B3 and CVM. Findings: There is some but not a general impact of elections and succession processes on SOEs. More recently, the impacts have increased. CEO turnover is greater in SOEs than in their private peers and changes in management are greater in cases of power shifts. Originality/value: We shed light on phenomena that happen frequently in Brazil: CEO successions in SOEs and political events impacting SOEs.

title: Do intangible assets matter to financial analysts in the Brazilian stock market?

description: Abstract Purpose: This paper aims to investigate how and to what extent intangible assets influence the evaluations of financial analysts covering companies listed on the Brazilian Stock Exchange (Brazil, Bolsa, Balcão: B3) from 2010 to 2016. Design/methodology/approach: The analysis was divided into two stages. In the first stage, we examined intangible asset taxonomies (i.e., structural, relational, and human capital) through content analysis by counting repeated key terms related to each category of intangible assets cited in the financial analysts’ reports. In the second stage, we analyzed the influence of intangible asset proxy variables on coverage, forecasting errors, and accuracy of earnings per share forecasts by financial analysts. Findings: In the first stage, the results suggested that analysts cited more terms related to the structural capital category, particularly the terms “strategy” and “mission.” In the second stage, the results pointed to the absence of statistically significant relationships between the studied variables. Therefore, it is possible to infer that although financial analysts covering firms in the Brazilian Stock Exchange cite terms related to intangible assets in their reports - which, in turn, points to the relevance of these assets during the company valuation process - the difficulty of conducting evaluations grounded on reliable bases, the scarcity of quality information about their development, and incentive problems may challenge or even prevent quantitative assessments targeted at capital market participants. Originality/value: By adopting an innovative methodological approach in the Brazilian context, this study highlights the fact that intangible assets influence financial analysts to a certain extent and they, in turn, manage to incorporate them into their analyses, although the statistical relationships have not been explicitly demonstrated.

title: Rating changes and the impact on stock prices

description: Abstract Purpose: The objective of this study is to analyze the impact of changes in credit ratings on the long-term return of Brazilian firms. Design/methodology/approach: We conducted an event study to measure how stock prices in the Brazilian stock exchange (B3) react to rating upgrades and downgrades by Moody’s and S&P. Findings: Our sample presents positive and significant returns measured by the BHAR for ratings downgrades and non-significant ones for upgrades. Our data also show the important role of the previous rating in explaining these results in a non-linear fashion. Originality/value: Our research makes an important contribution to the theory of market efficiency, analyzing the degree of information present in the announcements of credit ratings changes. We also present results for Brazilian companies, correcting gaps pointed out in previous methodologies.

title: Use of shrimp farm effluents for irrigation of Panicum maximum cvs.Tanzania and Mombaça

description: Abstract The study aimed to evaluate soil chemical changes and yield of two cultivars of Panicum maximum Jacq. (Tanzania and Mombaça) in response to irrigation with effluent from inland shrimp farming and compare the results with those obtained with conventional irrigation using river water. The experiment was carried out in a shrimp farm, in Russas-CE, Brazil. It was used a randomized block design, in a factorial 2 (grass cultivars) x 2 (types of irrigation water). The following yield variables were evaluated in four grass cuttings: height, dry matter yield and dry matter content. Data were analyzed by ANOVA and Tukey test. The following soil chemical properties were analyzed before and after treatment application: pH, electrical conductivity of saturated extract (CE), exchangeable sodium percentage (ESP), organic matter, P, K+, Ca2+, Mg2+ and Na+. Data were analyzed using t tests for paired observations, at 5% significance level. Irrigation with effluent from shrimp farming did not increased or reduced significantly dry matter yield of two cultivars of Panicum maximum as compared to irrigation with Jaguaribe river water. After 14 months of cultivation, levels of Na+, CE and ESP increased significantly (p &lt; 0.05) in the soil irrigated with effluent, as compared to the soil irrigated with river water.

title: Use of walking tractor powered rotary tiller in no-tillage system1

description: Brazilian family farming has at its disposal planters whose furrowing mechanisms, whether disc or shank, require a large vertical force. In smaller planters, this is reflected in low efficiency when opening the furrow or in a high demand for mass (weight). Rotary furrowers require less vertical force for the same operation. This study aimed to evaluate the technical feasibility and performance of rotary furrowers mounted on the powertrain of a walking tractor working under direct seeding, and compare them with shank-type furrowers using bibliographic data. The parameters used in the comparison were the depth and width of the furrow, the area of disturbed soil and the cross-sectional area of the furrow with no soil after the operation. The experiment was carried out on wheat stubble that had lain fallow for six months. Twelve treatments were employed in a factorial design: three models of rotary furrowers, two values for revolutions per unit of linear displacement, and two forward speeds. The variable, cross-sectional area of the furrow with no soil, was statistically affected only by the factor, furrower. However there was significant interaction between the factors, furrower, revolutions per metre and speed, for the variables of depth, furrow width and area of disturbed soil. The values obtained for the variables of width, depth and disturbed area in the cross-section of the furrows, with the three types of rotary furrowers driven by the powertrain of a walking tractor, were similar to those generated by shank-type furrowers.

title: Balance of longwave radiation employing the rate of solar radiation for Santa Maria, Rio Grande do Sul, Brazil1

description: New coefficients were determined for the weighting term for cloudiness in the Brunt-Penman equation using the rate of solar radiation (RK) in place of the rate of sunshine duration (n/N). The coefficients in the Brutsaert method proposed for daytime in southern Brazil were also tested and adjusted, and the method was selected which gave the more accurate daily results in relation to the original Brunt-Penman equation, for Santa Maria in the state of Rio Grande do Sul, Brazil (RS). Meteorological data covering 2,472 days obtained from the automatic and conventional weather stations in Santa Maria were used. The coefficients were adjusted by linear and nonlinear regression methods depending on the model, using 2/3 of the data. The adjusted equations were tested with the remaining 1/3 of the data. The Brunt-Penman equation modified by the term for cloudiness weighted both for solar radiation incident on the surface with no cloudiness (RK,R) and for solar radiation incident at the top of the atmosphere (RK,K), were those that resulted in the best statistical indices relative to the original Brunt-Penman equation. In those equations the boundary conditions, 0.3 ≥ RK,R ≥ 1 or RK,K ≤ 0.22, were imposed. Although having similar statistical indices, a sensitivity analysis showed that the Brutsaert equation and other weightings for cloudiness resulted in larger deviations when compared to the original Brunt-Penman equation, in addition to having greater complexity for practical application.
