Abstract. Walter Eucken's paradigm of a “social market economy” and “Ordnung” provides a framework for a functional free‐market mechanism, which not only accommodates development and change, but which also assures human dignity and freedom, as cornerstones of the Kantian moral universe. Eucken places special emphasis on the integration of economics with “order” and “Justice,” in a synthesis of negative liberty and positive freedom and of Rawls' and Nozick's theories of justice. Adam Smith's laissez faire economy does not assure a competitive economy, he holds, and will evolve into monopolistic practices, interventionism, and distortions of price relationships; but “structural” and “regulating” principles will facilitate a functionally competitive economy with a compatible social policy, characterized by a flexible price mechanism and stable policies. This “social market economy” would provide goods and services efficiently and also eliminate poverty and the maldistribution of income and resources.

Abstract. Labor and capital are usually considered as the primary factors of production, the costs of which are of utmost importance. In contrast, nature (including all natural resources), as the essential third factor, is disregarded. She is generally assumed to be always available, self‐regenerating, and to be exploited without long‐term costs. In other words, she is more or less viewed as a constant. Hans Immler's new treatise represents an important contribution in that he emphasizes the role and function of the natural environment, and its neglect, in the formulation of theories of value and their long‐term consequences on contemporary economic theories and on the person and society. This essay traces Immler's evaluation with extensive quotations—especially with regard to Physiocracy and the classical economists— of nature's role and function, or their neglect, in the formulation of theories of value through the writings of Aristotle, St. Thomas Aquinas, William Petty, John Locke, Adam Smith, David Ricardo, Karl Marx, and others—all dealt with in Part 1 of his book—and Francois Quesnay and the Physiocrats—the topic of Part 2.

PurposeThe socioeconomic as well as the political world has undergone significant changes, challenging the meaning and validity of economic and political paradigms. This treatise highlights that Eucken's paradigm of a “social market economy,” with its structural and regulating principles, needs to be modified to account for changing strategic factors.Design/methodology/approachNo economic theories, however relevant in the past, hold true for all time. This is verified by the dynamics of change as indicated by Hegelian dialectics, functionalism and structuralism, as well as by quantum theory.FindingsNational economies have become linked in the widening web of the global economy, exemplified, for example, by the European Union, the Euro Bloc, NAFTA, WTO, as well as by other trading arrangements. Enterprises have developed a global orientation, internationalizing their products and services, encouraging labor and capital to move instantaneously among industrialized countries, affecting social, fiscal, and monetary policies. Furthermore, these developments have increased awareness, on a global scale, about human rights and dignity, a healthy environment, changing demographics, and of limited natural resources.Practical implicationsThere is increasing awareness of contemporary challenges facing mankind and the environment, as well as the merging of national economies within a global framework. These challenges with their demands for modifications in socioeconomic as well as political policies may transform the paradigm of a “social market economy” into an “ecological social market economy”.Originality/valueTraditional economic theories usually consider capital and labor as the primary factors of production. Nature (all natural resources), on the other hand, tends to be neglected as an economic good and as an essential third factor of production. A political economy is suggested which assigns equal importance to man and nature, the costs of which have to be fully accounted for, including those for the preservation and regeneration of natural resources.
