Ajayi, Michael AdebayoOlufemi, Adewale Aluko2021-03-022021-03-022017http://hdl.handle.net/123456789/4401The controversy existing on the efficacy of monetary and fiscal policy to influence the economy is unending. This study evaluates the relative impact of monetary and fiscal policy in Nigeria from 1986 to 2014 using a modified St. Louis equation. Employing the Ordinary Least Squares estimation method, this study reveals that growth in money supply and export have a positive and significant effect on growth in output of the economy while growth in government expenditure has a negative and insignificant effect. This study provides evidence that monetary policy has a greater growth-stimulating effect on the economy than fiscal policy. It recommends that monetary policy rather than fiscal policy should be relied upon by the Nigerian government as an economic stabilisation tool.enMonetary policyFiscal policySt. Louis equationNigeriaArticle
