后凯恩斯主义经济学的货币非中性理论

后凯恩斯主义经济学的突出贡献是将凯恩斯关于不确定性和货币非中性思想发展为一个完整的关于货币非中性的理论框架,它强调无论是长期还是短期,货币都是影响真实部门的一个重要因素。后凯恩斯主义的货币理论在凯恩斯的灵活偏好理论中加入融资性需求,这样就必然导致存量和流量的矛盾,从而造成利息率的不确定性和波动性;从不同角度分析了货币的创造过程,提出了内生货币供给理论。这一理论完全是与主流经济学所信奉的货币数量论对立的,从而拒绝资本主义经济自然趋于长期充分就业均衡的概念。     

Perspectives for Post-Keynesian Economics

The paper reviews and assesses the negative and positive advice which has been offered by various fellow economists to heterodox economists in general, and Post-Keynesian economists in particular, in light of changes that have occurred within neoclassical economics and in light of the rising hegemony of mainstream economics in economics departments. Various strategies are considered, among which is more engagement with orthodox dissenters, but it is concluded that the majority of heterodox economists ought instead to engage more with other heterodox economists and possibly other social sciences, developing and expanding their own agenda around real-world problems.     

Central Banking and Post-Keynesian Economics

Abstract

The Post-Keynesian theory of endogenous money has given much attention to the role of the central bank in the money creation process. Circuit theory has neglected this role, in so far as it has focused on the relationship between banks and firms within a monetary production economy. The aim of this paper is therefore twofold. First, it intends to fill this gap in circuit theory, by providing a role for the central bank in settlement of interbank debts. Secondly, it aims at reinforcing the Post-Keynesian analysis of central bank money by considering both the money-purveying and the credit-purveying roles of the settlement institution in the interbank market. The result of this analysis is a more comprehensive theory of endogenous money, where the lender-of-last-resort facilities of a central bank are viewed as an endogenous phenomenon involving both a money creation and a credit operation between the central bank and the domestic banking system. In such a framework, monetary policy consists of setting the base rate of interest at a level that enables banks to limit their bilateral debt position in the interbank market, so as not to disrupt the workings of the payment system by either an illiquidity or an insolvency crisis.     

A Proposed Methodological Synthesis of Post-Keynesian and Institutional Economics

Post-Keynesian and institutionalist writers have commented on the theoretical and conceptual commonalities between the two schools. Some have suggested a theoretical synthesis based on these commonalities. In spite of these theoretical and conceptual commonalities each tradition has developed significantly different methods of analysis. Instead of theoretical or conceptual synthesis we seek here to present a methodological synthesis.

Institutionalist methods have yielded "plausible" explanations, but these have been too "vague and suggestive" to be consistently used for economic policy. Post-Keynesian methods have policy necessary "rigor," but the similarity to neoclassical methods has exposed post-Keynesian theories to unwarranted synthesis with incompatible traditions.

This essay presents a synthesis of post-Keynesian and institutionalist methodology, one of "plausible rigor," combining elements of "institutional dynamics" with a heuristic framework based on John Dewey's "instrumental logic," and proposes that the resulting approach overcomes weaknesses in the methods of analysis of both schools.     

A Post-Keynesian Model of the Palestinian Economy: The Economics of an Investment-Constrained Economy

The 60-year-old Israeli-Palestinian conflict has deeply influenced the evolution of the Palestinian economy. In the last two decades political instability and the Israeli closure policy have generated protracted economic stagnation and poor capital formation. The paper describes the consequences on the Palestinian economy of existing high transaction costs and market fragmentation. We propose a simple one-sector Post-Keynesian model that describes Palestine as a demand-driven economy. We show that high transaction costs and market fragmentation discourage investment by curtailing expected profitability, reducing the size of the market and depressing entrepreneurs' animal spirits. In the short run, these two factors induce low levels of capacity utilization and low rates of capital accumulation. The situation is even more worrying in the long run when entrepreneurs can revise their expectations. Depressed animal spirits and low levels of capacity use give rise to a low-growth trap from which Palestine can hardly escape. We also highlight the possible positive impact of the removal of high transaction costs and of market fragmentation, and the ensuing beneficial effects on the long-run equilibrium values of capital accumulation and capacity use. The conclusions place these analytical results into the historical situation of the Palestinian economy, and consider what is needed, politically and economically, in order to establish a sustained development process.

后凯恩斯主义的企业理论

后凯恩斯主义者认为在典型的两权分离的现代企业制度条件下,企业的目标是多元化的。但企业所有者和经理人的目标函数存在根本差别,所有者更偏好于企业利润目标,而经理人更偏好于企业增长目标。后凯恩斯主义者还区分了经理人资本主义化的企业和金融演化下的股东控制型企业两种模式。     

Post-Keynesian Theory: An Overview

Kregel provides the reader with an understanding of the evolution and current position of post-Keynesian economics. As in the past, its practitioners seek to explain the level of output and employment and its growth and distribution, recognizing “that money enters into the economic scheme in an essential and peculiar manner.”     

Macroeconomic Theorizing and the Instability of Post-Keynesian Capitalism

Financial innovations are associated with market crises. Hyman Minsky singles out financial innovations as particularly prone to instability so as to necessitate governmental intervention. Processes of innovation and diffusion in new products and in new financial instruments have commonalities as well as differences. This paper focuses on the differences with a view to better understand why financial innovations are more likely to generate significant negative repercussions. Differences that distinguish financial innovations include the role of intermediaries, variability in quality, and the extent of externalities. This paper further discusses the implications of these differences.
