This text has as main objective to calculate the users’ co-payment values in the Brazilian Farmácia Popular program (PFPB), as well as to explore potential factors associated with the co-payment rate in the program. The study is based on a rich set of data relating to product sales by...

This text has two objectives that complement each other. First, to investigate the behavior of social policy and its consequences. Then to assess whether Brazilians became more conservative, despite the progress seen in social actions. As a methodology, a descriptive analysis of data from...

Fixed Capital has a major role in economic growth literature and on the estimation of potential output using a production function - which is essential to design macroeconomic policy. One of the main contributions of this work, differently from the previous works, is to estimate the capital...

This paper describes and analyzes the trajectory of water and sanitation policies in Brazil, with emphasis on the Union acts on financing and regulation evolution in the sector. The objective is to point the different regulatory forms and models already tried, as well as to highlight the...

Public irrigation policy in Brazil aims to promote socioeconomic development focusing on economically disadvantaged regions that have agricultural potential. In the Northeast region, fruit exploitation plays an important role in the production. Irrigation projects in this region is an essential...

In this study, we undertook an econometric analysis aim to forecast the disaggregated series of ICMS administered by Confaz. Three methodologies were applied: i) the dynamic structural model (BSTS); ii) the dynamic linear model (MLD); and iii) the dynamic factorial model (MFD), all of them...

This text presents the main points of the debate about the mechanisms of attraction and facilitation of foreign direct investment. Recently several countries have questioned the traditional model of investment agreements. One of the remarkable dimensions in the agenda of several multinational...

In this paper we survey the most recent advances in supervised machine learning and highdimensional models for time series forecasting. We consider both linear and nonlinear alternatives. Among the linear methods we pay special attention to penalized regressions and ensemble of models. The...

There has been considerable advance in understanding the properties of sparse regularization procedures in high-dimensional models. In time series context, it is mostly restricted to Gaussian autoregressions or mixing sequences. We study oracle properties of LASSO estimation of weakly sparse...
