Résumé en anglais

Monetary policy contributes to stabilize growth. Particularly in a reforming context for financial and economic activities, it is important to know how central bankers’ decisions through the short term interest rate of the money market are transmitted to the real variables: the GDP and the inflation. Few studies on monetary transmission mechanisms deal with the Maghreb countries. Structural VAR are used to investigate the importance of various monetary transmission channels at a macro scale from convenient impulse response functions. As a result, the Tunisian central bank should mainly target inflation, focussing the interest rate channel and the long-term interest rate as the principal transmission variable.
