The purpose of this paper is to evaluate the efficiency in financial intermediation and the cost efficiency in banking service of credit unions in Brazil, based on essentially accounting variables, and to analyze the temporal evolution of the efficiency of these cooperatives.

With a sample of 315 cooperatives over the period from 2007 to 2014, this research uses a two-stage process: application of regression models with panel data to verify which variables are related to the defined outputs, with the reduction of 31 variables to 8 variables in both models; and application of the data envelopment analysis method to obtain an analysis of credit unions’ efficiency.

The results demonstrate a high level of efficiency in financial intermediation, with low variation over time, associated with a low efficiency in the banking service, in which few cooperatives have remained efficient over time. In addition, the cooperatives with highest efficiency in financial intermediation were also the most efficient in providing services.

This research has some limitations about the capacity of the proxies used to capture the real effect of the variables and assumptions of economic relations resulting in restrictions to generalize the results.

Cooperatives are usually analyzed under just one dimension. By separating the analysis into financial intermediation and banking services, cooperatives that are more efficient in each dimension can be identified, in addition to analyzing the evolution over time. The authors found that efficiency tends to be lower in banking services, and few cooperatives remain at the highest level of efficiency over time in both models.

Credit unions provide an important service in the banking and credit market. Therefore, understanding its operation and the characteristics that influence its efficiency allows a better management of the cooperatives themselves and a greater understanding of this important segment of the financial market.

The purpose of this paper is to examine the effects of length of service and ethical ideologies on cognitive moral development (CMD) and ethical behavioral intentions among public sector tax auditors in Brazil.

The research data were collected via survey questionnaires from a sample of 625 auditors who work for the Brazilian tax authority. Participants voluntarily complete an online instrument which included three scenarios with context-specific moral dilemmas, questions about the specific scenarios and an ethics position questionnaire. Multinomial logistic and ordinary least squares regressions were used to analyze the data.

The findings reveal that public sector tax auditors with shorter length of service are more likely to be at higher stages of moral development; relativistic ideology among public sector auditors is positively associated with more lenient ethical behavioral intention; idealistic ideology among public sector auditors is positively associated with stricter ethical behavioral intention; public sector auditors classified as absolutists are stricter in their ethical behavioral intentions; and public sector auditors classified as absolutists with length of service between 5 and 15 years are more likely to be at higher stages of moral development when compared to public sector tax auditors with longer length of service.

To the best of the authors’ knowledge, the study is one of the first studies that attempt to understand the effects of length of service and ethical ideology on CMD and ethical behavioral intention among public sector auditors. Additionally, it examines these issues in the context of Latin America.
