Abstract

This work builds upon “Keynes, Kalecki and Metzler in a Dynamic Distribution Model”. In that paper the dynamics of an economy from the ultra-short to the short period inside a Post-Keynesian perspective were studied questioning the general shared assumption of equilibrium between aggregate demand and aggregate supply in the short and long run Kaleckian models. This paper responds to some unresolved issues of the model proposed there considering a proper analysis of the Kaleckian investment function and a more realistic scenario with the presence of the government sector. Moreover, even if that model tried to deal with firms’ expectations in producing goods, some values boundaries were exogenously established. Here, those boundaries are questioned again. In fact, the novelty of this work is that an active role of the government can actually influence both the values of the expectations and their respective boundaries. It is argued that is particularly the case when the government is engaged in policies which aim is to support and secure a high level of economic activity and to smooth and steer the cycles phases toward a sustainable development path. Particularly we focus on the role of different fiscal policies aimed at obtaining such goals.

摘要

这项工作建立在“动态分布模型中的凯恩斯，卡莱基和梅茨勒”的基础上。在那篇论文中，研究了在后凯恩斯主义视角内从超短期到短期的经济动力，质疑了短期和长期Kaleckian模型中总需求和总供给之间均衡的一般共享假设。本文针对那里提出的模型中一些未解决的问题做出了回应，其中考虑了对Kaleckian投资函数的适当分析以及存在政府部门的情况下更现实的情况。而且，即使该模型试图解决企业在生产商品方面的期望，还是会在外部建立一些价值边界。在这里，这些界限再次受到质疑。实际上，这项工作的新颖之处在于，政府的积极作用实际上可以影响期望值及其各自的界限。有人认为，特别是当政府采取旨在支持和确保高水平的经济活动，并使周期阶段朝着可持续发展道路迈进和引导的政策时，情况尤其如此。特别是，我们专注于旨在实现这些目标的不同财政政策的作用。
