Frédéric Lordon 《Journal of Evolutionary Economics》1997,7(1):1-21
The slow and endogenous twist of economic macro-structure makes up an important evolutionary feature of capitalist economies,
and may be at the root of structural crisis. In this line, a Goodwinian growth model with increasing returns and profit-sharing
that tries to picture a simple scenario of the seventies crisis is considered. It is shown that the exhaustion of the Kaldor-Verdoorn
“productivity law” can entail, in a nonlinear framework, a “catastrophic” bifurcation from a “high” to a “low” growth path.
Slow/fast dynamical systems then allow one to formalize a multiple time-scales dynamics where the growth path is shaped by
the structural framework in which it takes place, but has also a long -un feedback. Structural change and crisis appear as
long term and endogenous outcomes. 相似文献

Changing trends and the nature of the work force dictate increased personal responsibility by employees and expanded use of
self-management practices. Nevertheless, organizations also feel the need to maintain external control. We propose a progressive
view of accountability theory which can resolve the dilemma of how internal and external control can effectively coexist.
Success of accountability forces is determined primarily by the relationship between the principal (party to whom one is accountable)
and the agent (employee). The agent’s felt responsibility is enhanced to the extent that accountability leads to the structuring
of expectations, the agent’s perceptions of the task or activity as significant, and the agent’s perception of control over
the situation. Propositions that may be used to guide future research are offered throughout the article. 相似文献

In this paper we study a generalization of the dynamic Leontief input–output model. We extend the standard dynamic Leontief model with the balance equation of non-renewable resources. Obviously, the non-renewable stocks will decrease, exploiting primary resources. In this study we examine the controllability of this extended model by taking the consumption as the control parameter. Assuming balanced growth for both consumption and production, we investigate how long these scarce resources will cover the input needs of production and how the lifetime of the system depends on the balanced growth rate and on the consumption. In doing so, we apply classic results from control theory and on eigenvalue problems in linear algebra. 相似文献

论制度变迁的成本约束 总被引:2,自引:0,他引:2
制度变迁的关键是成本约束,这是制度本身产生的根本性要求。制度变迁是成本和收益相权衡和比较的产物,制度设计和安排必须充分考虑到制度变迁的成本和收益,减少制度变迁的阻力,提高制度运行的效率。 相似文献

经济体制改革的理论基础不仅仅是社会主义市场经济理论,生态经济理论也是其中之一,这是由生态经济理论原则及特点所决定了的。同时,改革的目标是建立社会主义市场经济体制,在新体制的建立过程中,也必须注意实现生态经济协调的几个问题。 相似文献

Improved crop–fallow systems in the humid tropics can simultaneously sequester atmospheric carbon emissions and contribute to sustainable livelihoods of rural populations. A study with an indigenous community in eastern Panama revealed a considerable biophysical potential for carbon offsets in small-scale slash-and-burn agriculture through longer fallow periods, improved fallow management, secondary forest development, and agricultural intensification. Based on soil and biomass carbon measurements, estimated annual sequestration rates amount to 0.3−3.7 t C ha− 1 yr− 1. Despite such potential, the economic benefits of initiatives aimed at sequestration of carbon in the community are likely to be rather unequally distributed within the community. Heterogeneity in livelihood strategies and uneven asset endowments among households – factors often overlooked in the ongoing carbon and sustainable development debate – are expected to strongly affect household participation. Indeed, only the better-endowed households that have also managed to diversify into more lucrative farm and non-farm activities are likely to be able to participate in and thus benefit from improved crop–fallow systems that capture carbon. Economic, ethical, institutional, and technical concerns need to be taken into account when designing community carbon management and investment plans. 相似文献
