Abstract
In this paper, the following research question is answered: How can the
potential impact of the optimal policies of externalities trade to
uncouple growth and volatility in order to generate sustainable growth
and clean production be explored by the means of Agent-based modeling
(ABM)?
At this end, I attempt, to generalize the trade of everything to realize
the steady state. By considering any human action as causing positive or
negative externalities, the intergenerational and international
generalized trades become possible. Only this generalized trade conform
to the complex hypotheses of the neoclassical model whose
operationalisation immediately leads to the steady state, foundation of
a sustainable economy, without fluctuations and without destruction of
the environment and where all the productions are clean.
I find, generations import from other generations productive factors
intensively used in the production of goods and services highly consumed
in the current generations and export productive factors intensively
used in the production of goods and services weakly consumed in the same
generations. Indirectly, generations import goods and services that use
a high proportion of technically scarce productive factors and a low
proportion of technically abundant productive factors and export goods
and services that use the reverse proportions of the same productive
factors. Thus, positive externalities (unnatural resources) are
exchanged against negative externalities (overconsumption of natural
resources). A productive factor is technically scarce in a generation if
the part of this productive factor imparted to this generation is
insufficient to produce as much of these goods and services that it
wishes to consume. A productive factor is technically abundant if its
proportion existing in this generation is superior to its production
needs. Under these conditions, I show, at the equilibrium level, each
productive factor and each good or service has the same price in each
generation. This realizes an efficient trade of externalities decoupling
thus growth and volatility. That is why I conclude the policies to
uncouple growth and volatility are also those of sustainable growth and
clean production, ensuring to each generation an equivalent use of
natural and unnatural resources. In contrast to AK model, I find,
through widened evidence that, a greater willingness to hoard or an
improvement in the level of technology shows up in the long run that
higher levels of capital (unnatural resources) and output per effective
worker are achieved, with no change in per capita growth rate. The
steady state results in diminishing returns to inputs in the technology
production. At this end, I propose, countries or generations with a high
price deviation should pay to the World Environmental Bank (WEB) a tax
that would be proportional to its price deviation or its growth
volatility path. (C) 2019 Elsevier Ltd. All rights reserved.
