The ideological foundations of the contributors range from personalized neo-Marxism, through "extreme centre" neo-Keynesianism, to hard-line neoclassical mathematical economics. Despite this diversity there is a surprising degree of consensus. No contributor advocates centralized planning and none expects a free market to cure all economic ills. Opinions vary as to how well the market actually works, but all agree that equity and efficiency are essential goals which most consider to be complementary rather than mutually exclusive. In the concluding chapter it is suggested that current economic problems are caused not so much by government intervention as by the nature of that intervention. The authors believe that the recent ideological convergence may lead to a new paradigm, a theory of the optimal blend of market and management that will be flexible enough to deal with the varying conditions of diverse societies, thus simplifying the task of creating a smooth-running global economy.
