Monetary policy transmission mechanism in Botswana: how does the Central Bank policy rate affect the economy?

Magister Economicae - MEconThe transmission mechanism of monetary policy has generated a substantial amount of interest in economic research in many countries, with most studies focusing on how a change in monetary policy stance, usually defined as an exogenous shock in a short-term interest rate, affects the economy at a national level, with changes in output, inflation and exchange rates being the key variables under investigation. This study adopts a similar analysis, with the general objective of examining the effectiveness of monetary policy in Botswana. Specifically, this study aims at finding out how the central bank rate affects inflation in Botswana and the duration of its effects on economic variables in Botswana. The study adopts the recursive VAR methodology, using quarterly data from 1995 quarter one to 2009 quarter four.
