The evolution of the yields of different maturities is related and can be described by a reduced number of commom latent factors. Multifactor interest rate models of the finance literature, common factor models of the time series literature and others use this property. Each model has advantages...

Based on three versions of a small macroeconomic model for Brazil, this paper presents empirical evidence on the effects of parameter uncertainty on monetary policy rules and on the robustness of optimal and simple rules over different model specifications. By comparing the optimal policy rule...

Space-varying regression models are generalizations of standard linear models where the regression coefficients are allowed to change in space. The spatial structure is specified by a multivariate extension of pairwise difference priors thus enabling incorporation of neighboring structures and...

Regulation in the sanitation sector in Brazil is facing a great deal of debate regarding the government level in which conceding authority should reside and how private operators can fulfill social objectives. The main objective of this study is to show that these issues are not the crucial...

The objective of our work is to study the term structure of interest rates and the sovereign credit spreads of emerging markets. We develop a model from term structure, credit risk and vector autoregressive models, based on the articles by Ang and Piazzesi (2003) and Ang, Dong and Piazzesi...

We propose a management tool to identify groups of public schools that have similar standards of performance and therefore need similar support and guidance.The student's result is measured with the "Prova Brasil" (PB) for mathematics and for Portuguese language, and with an indicator of the...

Institutional characteristics of each country acquire increasingly importance in the economic literature of the determinants of growth, investment and risk perception, especially in emerging economies. The objective of this work is to quantitatively assess the impact of institutional quality...

It is almost a consensus that the ongoing transformations in the Brazilian demographic structure press for urgent changes in the current social security rules as the objective of guaranteeing the actuarial balance of the national pension system. It is therefore important to predict the impact of...
