BURUNDI CASE STUDY

Methodology and Data Data are monthly frequency : April 2010 – December 2013 Series are GDP, M2, CPI, NEER, LABOR & OILP Steps: Testing stationarity Lag specification VAR stability Causality Impulse response

STATIONARITY TEST trend constant Critical Values 2.79 and 3.53 GDP -0.137 -1.873 INF -0.0322 -0.7008 M -5.267 -1.097 TCEN -0.348 -1.733 CPI -1.561 -0.372 LABOR -0.029 -2.168 OILP -1.0004 -4.022 The series are difference stationary and are not depending up trend nor constant according to the results highlighted
