An important aspect of empirical research based on the vector autoregressive (VAR) model is the choice of the lag order, since all inference in the VAR model depends on the correct model specification. Literature has shown important studies of how to select the lag order of a nonstationary VAR...

In this article we study the deposit-taking and lending behavior of Brazilian banks before and after the subprime crisis. The distribution of both series present changes between these two periods. In addition, we implemented a vector autoregression model in order to construct the impulse...

Lucas(1987) has shown a surprising result in business-cycle research: the welfare cost of business cycles are very small. Our paper has several original contributions. First, in computing welfare costs, we propose a novel setup that separates the effects of uncertainty stemming from...

This paper has two original contributions. First, we show that PV relationships entail a weak-form SCCF restriction, as in Hecq et al. (2006) and in Athanasopoulos et al. (2011), and implies a polynomial serial correlation common feature relationship (Cubadda and Hecq, 2001). These represent...

This research presents a pioneering contribution to the literature on the transmission mechanism of monetary policy through the credit channel and the risk-taking channel, since it analyzes the influence of monetary policies on the insurance hiring process by banks in order to protect them...

We study the joint determination of the lag length, the dimension of the cointegrating space and the rank of the matrix of short-run parameters of a vector autoregressive (VAR) model using model selection criteria. We consider model selection criteria which have data-dependent penalties as well...

This paper tests the Rational Expectations Hypothesis in Brazil from July 1996 to December 2001 for maturities ranging from 1 day to 1 year. It shows that (i) the estimated coefficients in the regressions of the short-run changes of the long rate on the yield spread and in the regressions of the...
