This paper presents new econometric specifications for the Brazilian exports in the period 1995-2009 using data from the Quarterly Accounts and allowing for nonlinearities. In the cointegrating vector, there is evidence of a level shift, but the elasticities have not changed significantly. The...

This paper shows new econometric estimates for the Brazilian function of aggregate imports. Besides the basic relation, which includes income and relative price and identifies a demand equation (canonic model), we explore the pronounced co-movements between total imports, household consumption...

This paper presents new econometric specifications for the quarterly behavior of the aggregate consumption of Brazilian households in the 1995-2009 period. It is argued, in particular, that the use of quarterly measures of both private disposable income (in chained 1995 prices) and the credit...

We apply and test term structure fitting models like polynomial splines, flat forward and Nelson-Siegel to the Brazilian local term structure. They are models used all over the world by authorities and financial markets practitioners but less known locally. These models were tested with a large...

Portuguese Abstract: Apresentamos os modelos Spline polinomial, Flat Forward e Nelson-Siegel para a interpolação da estrutura a termo da taxa de juro. São modelos adotados internacionalmente por praticantes e autoridades monetárias, mas pouco conhecidos na literatura local. Testamos os...

English Abstract: The long-horizon event study methodology is used to document the severe impact of the US subprime mortgage crisis on the Colombian economy. The estimated parameter of a constant mean return model is used to derive the “abnormal return” on the market portfolios of Colombia...

The forecasting of government revenues is extremely important for an adequate budget execution, since a good accuracy in the estimation allows the stipulation of an expenditure level that meets the demands of the population. Using data released by the National Council of Treasury Policy, the...
