Faz uma comparação entre o sistema brasileiro de execução fiscal e o de seis países selecionados: França, Alemanha, Estados Unidos da América (EUA), México, Chile e Argentina. Mediante comparação, busca-se entender se de fato há uma ineficiência crônica no modelo brasileiro e identificar experiências internacionais que permitam aprimorar esse quadro.

El uso de (grandes) corpus textuales como base empírica para el análisis de fenómenos gramaticales ocupa un lugar central dentro de la lingüística contemporánea. La gramática histórica del español no es ninguna excepción, y desde principios del presente milenio los historiadores de la lengua disponen de dos grandes corpus diacrónicos ampliamente usados en el mundo entero, como son el CORDE de la Real Academia Española y el Corpus del español de Mark Davies (2002-). Al lado de los grandes corpus muestras de textos de menor extensión, pero con características relevantes para la investigación en cuestión, también se utilizan como base de análisis empíricos.

Forecast is the basis for making strategic, tactical and operational business decisions. In financial economics, several techniques have been used to predict the behavior of assets over the past decades.Thus, there are several methods to assist in the task of time series forecasting, however, conventional modeling techniques such as statistical models and those based on theoretical mathematical models have produced unsatisfactory predictions, increasing the number of studies in more advanced methods of prediction. Among these, the Artificial Neural Networks (ANN) are a relatively new and promising method for predicting business that shows a technique that has caused much interest in the financial environment and has been used successfully in a wide variety of financial modeling systems applications, in many cases proving its superiority over the statistical models ARIMA-GARCH. In this context, this study aimed to examine whether the ANNs are a more appropriate method for predicting the behavior of Indices in Capital Markets than the traditional methods of time series analysis. For this purpose we developed an quantitative study, from financial economic indices, and developed two models of RNA-type feedfoward supervised learning, whose structures consisted of 20 data in the input layer, 90 neurons in one hidden layer and one given as the output layer (Ibovespa). These models used backpropagation, an input activation function based on the tangent sigmoid and a linear output function. Since the aim of analyzing the adherence of the Method of Artificial Neural Networks to carry out predictions of the Ibovespa, we chose to perform this analysis by comparing results between this and Time Series Predictive Model GARCH, developing a GARCH model (1.1).Once applied both methods (ANN and GARCH) we conducted the results' analysis by comparing the results of the forecast with the historical data and by studying the forecast errors by the MSE, RMSE, MAE, Standard Deviation, the Theil's U and forecasting encompassing tests. It was found that the models developed by means of ANNs had lower MSE, RMSE and MAE than the GARCH (1,1) model and Theil U test indicated that the three models have smaller errors than those of a naïve forecast. Although the ANN based on returns have lower precision indicator values than those of ANN based on prices, the forecast encompassing test rejected the hypothesis that this model is better than that, indicating that the ANN models have a similar level of accuracy . It was concluded that for the data series studied the ANN models show a more appropriate Ibovespa forecasting than the traditional models of time series, represented by the GARCH model
