    • Testing covariance stationarity 

      Xiao, Zhijie; Lima, Luiz Renato Regis de Oliveira
      2006-11-01
      In this paper, we show that the widely used stationarity tests such as the KPSS test have power close to size in the presence of time-varying unconditional variance. We propose a new test as a complement of the existing ...

    • Testing for super-exogeneity in the presence of common deterministic shifts 

      Toro, Juan
      2001-11-22
      This paper introduces the concept of common deterministic shifts (CDS). This concept is simple, intuitive and relates to the common structure of shifts or policy interventions. We propose a Reduced Rank technique to ...
    • Testing unit root based on partially adaptive estimation 

      Xiao, Zhijie; Lima, Luiz Renato
      2004-03-01
      This paper proposes unit tests based on partially adaptive estimation. The proposed tests provide an intermediate class of inference procedures that are more efficient than the traditional OLS-based methods and simpler ...
    • To cointegrate or not to cointegrate? That's a topological question 

      Flôres Junior, Renato Galvão
      1997-10-16
      We show that for any multivariate I( 1) process which does not cointegrate, it is possible to find another process sufficient1y elose to it where cointegration applies. Closeness is defined in terms of the spectral density ...
    • Tópicos clássicos de econometria 

      Pereira, Alexandre Porciúncula Gomes
      1987-11-01
    • Tópicos em Econometria Aplicada 

      Rodrigues, Claudia Oliveira da Fontoura
      2009-12-14
      This paper has three original contributions. The first is the reconstruction of employment and income series to allow the creation of a new coincident index for the Brazilian economic activity. The second is the construction ...
    • Two heads may not be better than one : corporate board structure, managerial self-dealing,and common agency 

      Carrasco, Vinicius
      2004-09-16
      This paper compares the effects on corporate performance and managerial self-dealing in a situation in which the CEO reports to a single Board that is responsible for both monitoring management and establishing performance ...
    • A unit root test based on partially adaptive estimation 

      Lima, Luiz Renato Regis de Oliveira
      2003-09-11
      This paper constructs a unit root test baseei on partially adaptive estimation, which is shown to be robust against non-Gaussian innovations. We show that the limiting distribution of the t-statistic is a convex combination ...
