There is little debate about the main goals of macroeconomic policy (full employment, absence of inflation, rapid economic growth, a balanced budget, etc.). However, when answering the question what instruments should be used to accomplish these goals, some differences arise. Different theoretical approaches to identical problems often suggest completely different instruments. Apart from the first dilemma, what school of thought is right, there is another dilemma: is it possible to reach a synthesis of alternative theoretical approaches, such as a consensus which was present in economic policy during 1960'. Two approaches to this problem are offered in this paper. The first assumes that such a synthesis is not possible and, depending on the observed situation, a selection of a specific school is made. The second approach assumes the possibility of such a synthesis based on ten common variables.
