The Multidimensional Trade Theory and Ramsey Effects: Biological Metabolism as Experimental Test on Sustainability

Abstract Our aim in this paper was to determine whether multidimensional trade theory is sufficiently similar to metabolic processes so that what can be said of or done with metabolic processes also applies to multidimensional exchange. The theory of multidimensional trade (Edgeweblime, 2019) states that factors of production in abundance in one generation and are not intensively used to produce goods and services in that generation are exported to other generations in exchange for scarce factors of production intensively used to produce goods and services that should be scarce in the generation under consideration : Does a multidimensional exchange mechanism exist in the human organism, involving almost complete compensation between negative and positive externalities, to determine either the volatility of human growth that reduces life expectancy or the optimal life expectancy analogous to either the volatility of economic growth or the optimal or sustainable growth of an economy? More specifically, the aim of this study was to investigate the impacts of non-Pareto-optimal Walrasian equilibria in the exchange of externalities between neurotransmitter secretion centers and/or between generations of neurotransmitter secretion centers as a fundamental mechanism of human growth volatility leading to disruptions in life expectancy. This would confirm the theory of multidimensional exchange, enabling policymakers to summon the same remedies as in modern medicine. The existence of several hormone or neurotransmitter secretion or synthesis centers and their distribution in the organism according to their specificity and, above all, their productivity in terms of carnal or spiritual satisfaction merit consideration. In multidimensional exchange, the existence of multiple generations of human beings succeeding one another in the same country, just as generations of cells are continually renewed during the life of the organism, on the one hand, and the existence of various separate centers of synthesization, just as countries are separated by borders so that the assumptions of virtual immobility of neurotransmitters and real mobility of carnal and spiritual satisfaction can be retained in both systems of exchange, on the other, is truly intriguing. Moreover, multiple concepts and phenomena (volatility, stationary states, equilibria, exchange, time, information, marginal utility, productivity, marginal productivity, partial specialization, the frontier of production or consumption possibilities, efficiency etc.) have been deemed relevant in both types of exchange.The analogy seems established. However, given that metabolism is a very specific phenomenon, we need more elaborate comparative studies on both sides of the veil between the two sciences. The multidimensional exchange model and the Neoclassical model have devised many hypotheses that remain a mystery to biologists and need to be confirmed. At first glance, a rapprochement between the two sciences would be salutary. Economics would gain in precision and rationalization, while biology would have so many hypotheses to study.
