On the one hand, the keynesian economists are the ones that support the intervention of the government in the economy and therefore that they primarily believe that in order to incentive the economy the government should increase spending or at least reduce taxes with the purpose of stimulate the demand of the population so that the production increases

On the other hand, the classical and monetarist economists are the ones that support the fact that the government should not be part of any type of decision when it comes to the economy of the country and therefore that they support the idea that when the government decides to increase the money supply then the inflation rates automatically jumps to higher levels
