ABSTRACT
The study examined the impact of monetary policy in stabilizing the Nigeria economy. In the model specified inflation is the regress while cash research requirement, liquidity ratio, money supply, minimum rediscount rate, interest rate are the regressors. The government employs a deliberate manipulation of cost and availability of credit and money to achieve this economic objective. The CBN being the sole regulatory body combines measures designed to regulate the value, supply and cost of money into economic activities. This is what we call monetary policy (CBN Brief 1996/03). It is against this background that the research is carried out to ascertain the effect in the use of monetary policies such as money supply, interest rate, liquidity ratio, minimum rediscount rate, inflation rate and cash reserve requirement to stabilize the Nigeria economy. Also to determine the relationship that exists between the independent variables and dependent variable from the secondary data for the period under study (1980 – 2010). The statistical technique that will be used for this analysis is the ordinary least square technique, with the aid of PC five 8.00 software package. It has been identified that the major problem militating against the poor performance of monetary policy instruments in stabilizing the economic in Nigeria is time – lags which involves policy employed to take many months to achieve its full effects. This research recommends that there should be a reduction in the cost of production and increase the exportation in order to achieve the objectives of naira devaluation in Nigeria and also, central banks should be independent and should be able to achieve its inflation targets and the stabilization of growth rate in money supply.
