The New Classical Counter-Revolution: False Path or Illuminating Complement?

In this paper the author responds to Laurence Seidman’s recent article, ‘The New Classical Counter-Revolution: A False Path for Macroeconomics’. The author challenges the view that new classical macroeconomics has been a false path and provides a critique of Seidman’s arguments with respect to his interpretation of the 1970s ‘stagflation’, the relevance of new classical macroeconomics for practical policymaking, the contribution of real business cycle theory, and the new classical content of contemporary macroeconomic textbooks. The author concludes that the new classical counter-revolution has had an extremely productive influence on the current mainstream new neoclassical synthesis framework.

Endogenous Growth: A Kaldorian Approach

This chapter explores the Kaldorian approach to endogenous growth theory. The central principles of this approach are explored, including the claims that growth is: (a) demandled, with trade playing a central role in aggregate demand formation; and (b) pathdependent. It is shown that both the actual and natural rates of growth are path dependent in the Kaldorian tradition. The implications of inequality between the actual and natural rates of growth are investigated, and it is shown that mechanisms exist within the Kaldorian tradition that are capable of reconciling these growth rates. This results in the sustainability (in principle) of any particular equilibrium value of the actual rate of growth.endogenous growth, Kaldor, path dependence, demand-led growth, technical change, institutions, natural rate of growth

Birth and Early History of Nonlinear Dynamics in Economics

Desde comienzos de los ’80, la elaboración de modelos no lineales se está volviendo una metodología cada vez más popular en economía. Sin embargo, no es tan novedosa como muchos investigadores parecen creer. Antes de que el enfoque lineal dominara a la teoría económica alrededor de los ’50, muchos economistas se encontraban comprometidos con el desarrollo de modelos no lineales, especialmente durante el período 1930-1950. El principal objetivo de este ensayo es proporcionar una revisión sistemática de los desarrollos pioneros en dinámica no lineal en economía, desde el modelo original de impulso y propagación de Frisch en 1933, hasta la formalización de Goodwin del ciclo límite en 1951. Since the 1980s, nonlinear dynamic modelling is becoming a popular methodology in economics. However, it is not as new as many researchers seem to believe. Before the linear approach dominated economic theory around the 1950s, many economists were actively involved in the development of nonlinear models, this tendency being particularly strong during the period 1930-1950. The main objective of this essay is to offer a systematic and comprehensive survey of the early developments in nonlinear dynamics in economics, ranging form Frisch’s original impulse and propagation model in 1933, to Goodwin’s formalisation of the limit cycle in 1951.modelos no lineales, ciclos económicos, macrodinámica, fluctuaciones endógenas/exógenas, historia del pensamiento 1930-1950, nonlinear modelling, economic cycles, macrodynamics, endogeneous/exogenous fluctuations, history of thought 1930-1950

The Cost Channel of Monetary Policy in a Post Keynesian Macrodynamic Model of Inflation and Output Targeting

This paper contributes to the debate about whether or not inflation targeting is compatible with Post Keynesian economics. It does so by developing a model that takes into account the potentially inflationary consequences of interest rate manipulations. Evaluations of the macroeconomic implications of this so-called cost channel of monetary policy are common in the mainstream literature. But this literature uses supply-determined macro models and provides standard optimizing microfoundations for the various ways in which the interest rate can affect mark-ups, prices and ultimately the form of the Phillips curve. Our purpose is to study the implications of different Phillips curves, each embodying the cost channel and derived from Post Keynesian, cost-based-pricing microfoundations, in a monetary-production economy. We focus on the impact of these Phillips curves on macroeconomic stability and the consequent efficacy of inflation and output targeting. Ultimately, our results suggest that the presence of the cost channel is of less significance than the general orientation of the policy regime, and corroborate earlier finding that, in a monetary-production economy, more orthodox policy regimes are inimical to macro stabilization.Cost channel of monetary policy, incomes policy, inflation targeting, macroeconomic stability

Income Distribution, Credit and Fiscal Policies in an Agent-Based Keynesian Model

This work studies the interactions between income distribution and monetary and fiscal policies in terms of ensuing dynamics of macro variables (GDP growth, unemployment, etc.) on the grounds of an agent-based Keynesian model. The direct ancestor of this work is the "Keynes meeting Schumpeter" formalism presented in Dosi et al. (2010). To that model, we add a banking sector and a monetary authority setting interest rates and credit lending conditions. The model combines Keynesian mechanisms of demand generation, a "Schumpeterian" innovation-fueled process of growth and Minskian credit dynamics. The robustness of the model is checked against its capability to jointly account for a large set of empirical regularities both at the micro level and at the macro one. The model is able to catch salient features underlying the current as well as previous recessions, the impact of financial factors and the role in them of income distribution. We find that different income distribution regimes heavily affect macroeconomic performance: more unequal economies are exposed to more severe business cycles fluctuations, higher unemployment rates, and higher probability of crises. On the policy side, fiscal policies do not only dampen business cycles, reduce unemployment and the likelihood of experiencing a huge crisis. In some circumstances they also affect positively long-term growth. Further, the more income distribution is skewed toward profits, the greater the effects of fiscal policies. About monetary policy, we find a strong non-linearity in the way interest rates affect macroeconomic dynamics: in one "regime" with low rates, changes in interest rates are ineffective up to a threshold beyond which increasing the interest rate implies smaller output growth rates and larger output volatility, unemployment and likelihood of crises.agent-based Keynesian models, multiple equilibria, fiscal and monetary policies, income distribution, transmission mechanisms, credit constraints

The Global and Local in Phillips Curve\ud

The debate over the Phillips Curve - as the relation between level of unemployment rate and inflation rate - in historical economics is shortly reviewed. By using the analysis in the Extreme Value Theory, i.e.: the rank order statistics the unemployment and inflation data over countries from various regions are observed. The calculations brought us to conjecture that there exists the general pattern that could lead from the relation between unemployment and inflation rate. However, the difference patterns as observed in the Phillips Curve might could be reflected from the range of values of the local variables of the incorporated model.\u
