A realist appraisal of post-Keynesian pricing theory

This paper argues that, based on the ontological insights ofcritical realism, epistemological guidelines can be establishedto review post-Keynesian pricing theories critically. Consequently,the paper suggests a basis on which the coherence of post-Keynesianpricing theory can be established. Crucially, some often-citedcontributions are inconsistent with such a realist-defined post-Keynesianeconomics. The role of empirical work in critical realism isdiscussed.     

Keynes and a post-Keynesian controversy over the effect of debt on income expansion

The paper considers arguments of Robertson (1938) and Asimakopulos (1983) that the Keynesian multiplier expansion of output may be constrained by debt implicitly incurred in the financing of autonomous investment necessary to start the multiplier process. The task of this essay is to show that within the ‘short-period’ and static analytical framework of Keynes, this line of reasoning regarding the adverse effects of debt on multiplier-induced expansions of output is unwarranted. Nevertheless it is concluded that if the Keynesian framework is abandoned in favour of a dynamic framework in the manner of a steady trend rate of growth - a choice dependent on how one conceives of the economy, as inherently static or dynamic - then such arguments have troubling implications. In particular, the dependence of Keynes's approach on credit and hence debt forges links between ‘short-periods' whose distinctness from one another is crucial to Keynes's result.     

Keynes against Kalecki on economic method

In the past twenty years, there has been considerable debate on the “coherence” of post Keynesian economics, in view of post Keynesian economists’ ambitions to develop a paradigmatic alternative to neoclassical economics. Given the growing importance of methodological aspects in this discussion, this article addresses the differences of approach to economic theory between the fathers of the two most important strands in post Keynesian economics. We thus focus on Keynes’s criticism of Kalecki’s theory of the business cycle and the tensions between Keynes’s logical approach and Kaleki’s formal modeling. We show that in criticizing Kalecki’s theory, Keynes made use of the same methodological criticism (based on detecting logical fallacies in reasoning) he had employed to attack both the classical theory and contemporary “pseudo-mathematical” models. After illustrating these fundamental differences between Keynes and Kalecki about the proper way of doing economics, we draw some conclusions on the possible future evolution of post Keynesian economics.     

Toward the crisis: a Kaleckian-Keynesian interpretation of the instability of growth and capital accumulation in Brazil

This article examines theoretically and empirically the instability of Brazilian investment and growth for the past couple of decades, highlighting the evolution that led to the current crisis. A theoretical discussion highlights the importance of Kaleckian and Keynesian approaches in understanding the semi-stagnation of the Brazilian economy since the 1990s. Empirical evidence shows that investment has increased until 2013, but not to the point of getting the economy back on the track of high growth rates and higher investment-GDP ratios. The econometric findings are compatible with the theoretical underpinnings of investment activity based on Keynes and Kalecki and suggest the existence of room for activist policies in Brazil in order to stimulate economic activity.     

Economic history and history of economics

Trust, along with other influential norms of cooperation, has been traditionally viewed as an important coordination mechanism stabilizing expectations of the participants in the informal economic exchanges. Drawing on the example of the informal value transfer system called hawala, this paper, however, shows that the role of safeguard against opportunism in the informal monetary settings is much more reliably performed by the instruments of social control. Norms of control embedded in community beliefs and common social practices among the hawala members entirely replace trusting attitudes, rendering them superfluous for the purpose of protecting financial interests of clients and intermediaries in this informal system of monetary exchanges.     

Against the current: Sraffa's unpublished manuscripts and the history of economic thought *

The paper throws some new light on Sraffa's contribution, using material from his yet unpublished papers. Attention focuses on Sraffa's rediscovery of the distinct character of the classical theory of value and distribution and his refutation of the Marshallian interpretation that it is only a special case of demand and supply theory, his reformulation of the classical theory, and his criticism of the alternative neoclassical theory.     

On the links between unemployment rate, monetary creation and the value-added sharing

In this paper, we investigate the analytical links between the rate of unemployment, monetary creation and how individuals share the value added in an economy with three types of agents: capital owners, managers and employees. This relationship relies on the fact that the rate of unemployment depends on many macroeconomic characteristics such as: creation of money, external balance of goods and services and mark-up pricing. The latter being decomposed into the expected margin rate and the growth rate of the unitary wage cost that characterize the primary value-added sharing.     

Shackle on Equilibrium: A Critique

This paper presents a critical evaluation of Shackle's views on economic method. Shackle's arguments against equilibrium analysis are shown to apply to orthodox theory, which has subjectivist foundations, but not to the objectivist classical approach associated with Sraffa. The long-period equilibrium method is indispensable to the analysis of how market societies function. Moreover, since the classical theory contains no trace of the factor substitution mechanisms that underpin neoclassical orthodoxy, its explanations of distribution, employment and outputs must take explicit account of institutions, power and ethical norms. Thus there is no conflict between social economics and the method of the classical economists and Sraffa. On the contrary, the classical approach provides a rigorous framework for the investigation of the very issues that are at the center of institutional and social economics.     

Epistemology and the tasks of feminist economics

This paper examines the implications of current epistemological debates for the work of feminist economists. Feminist economists must acknowledge (in accordance with recent developments in the study of science) that (a) inquirers can never be certain whether claims about the world are true; (b) scientific inquiry is permeated with “internal” and “external” values; and (c) beliefs are affected by inquirers' social locations. But feminists should not, it argues, embrace the “relativist” stance of some postmodern thinkers, or reject the ideal of “truth,” or argue that beliefs are strictly determined by inquirers' identities and interests. It seeks to outline an epistemological “middle ground” for feminist economics, between the extremes of exaggerated claims of certainty and a disempowering relativism.     

A reformulation of the foundations of welfare economics

Neoclassical welfare economics takes an outcome-oriented approach that uses Pareto optimality as its benchmark for welfare maximization. When one looks at the remarkable improvements in economic welfare that have characterized market economies, most of those improvements in welfare have been due to economic progress that has introduced new and improved goods and services into the economy, and innovations in production methods that have brought costs down, leading to higher real incomes. Pareto optimality is only peripherally related to actual economic welfare, and no economist would argue that people are materially better off today than a century ago because the economy is closer to Pareto optimality. After analyzing the actual factors that lead to improvements in welfare, this paper suggests a reformulation of the foundations of welfare economics to replace the almost irrelevant outcome-oriented concept of Pareto optimality as the benchmark for evaluating welfare with a process-oriented benchmark based on factors that generate economic progress. The paper then explores some implications of this reformulation.

Naturalised epistemology and economics

The relevance to economics of naturalised epistemology (alsoknown as the naturalistic turn) from philosophy of science hasrecently been argued by economic methodologists, especiallyby D. Wade Hands (Reflection Without Rules: Economic Methodologyand Contemporary Science Theory, Cambridge, Cambridge UniversityPress, 2001). This concept is held by Hands to constitute partof the ‘new economic methodology’ that consistsof the ‘interpenetration of economics and science theory’.Contrary to Hands's case, naturalised epistemology is shownhere not to represent a qualitatively new concept, to possesslittle coherent meaning, and to be incapable of charting aninnovative way forward for economics. Although there are moreissues concerning naturalism bearing on economics than are notedby Hands, three specific limitations of naturalised epistemologyare discussed. These and other limitations are related to theeconomics examples Hands proposes suggesting the usefulnessof naturalised epistemology for economics.     

Do Educational Attainments Influence Attitudes Toward Gender Equality in Sub-Saharan Africa?

Abstract

Although there is a plethora of literature on gender equality and women empowerment, studies on whether (and to what extent) educational attainments affect people’s attitudes toward gender equality are lacking. This is particularly true for Africa, a mostly male-dominated continent. In this article, we use data from the Wave 6 of the World Values Survey to empirically examine the relationship between educational attainments and attitudes toward gender equality among people in 5 countries in Africa–Ghana, Nigeria, Rwanda, South Africa, and Zimbabwe. Our results, based on different measures of gender equality and econometric specifications, consistently reveal that the higher the level of education acquired, the more liberal and favorable the individual’s attitudes are toward gender equality.     

Health economics of medical devices: opportunities and challenges

Expenditure on medical devices is substantial and is expected to grow in the future. This Editorial draws attention to health economic issues surrounding medical devices. To this effect, opportunities and challenges involved in the economic analysis of the market structure of medical device sectors and in the economic evaluation of medical devices are identified.

Markets for medical devices tend to be fragmented and suffer from a lack of transparency and competition. In response to this, there is extensive government intervention in many developed countries with a view to keeping down prices, restricting public reimbursement and promoting an efficient use of medical devices. Studies are called for that evaluate and compare country approaches towards regulating medical device markets with a view to informing medical-device policies.

Whereas economic evaluation of medicines is well established, and is used to inform pricing and reimbursement decisions in many developed countries, this is less the case for medical devices. There is a need for economic evaluations of medical devices with a view to demonstrating their cost effectiveness. In addition, countries need to implement frameworks for the assessment of new and emerging medical devices with a view to taking pricing and reimbursement decisions.     

Notes and comments. A re(in)statement of the labour theory of value: a comment

The aim of this paper is to show that the main conclusions inMohun's (1994) paper rest on an implicit assumption: the compositionof net output has to remain constant. When this is removed,some paradoxical results are obtained.     

When economics harmonized mathematics in Japan: a history of stability analysis

This article discusses how economics was mathematized by Japanese theoretical economists with the cooperation of Japanese mathematicians before 1950. Mathematicians played the leading part in assimilating European scientific ideas and providing an internationally oriented attitude in Japan from the mid nineteenth century. They began to publish many updated textbooks in Japanese from around 1930 on. In the 1940s, Japanese mathematical economists were intensively studying the so-called stability problem, thereby mathematizing economics more rapidly than ever before. Their research activity will give us an interesting example of a process of organizing economic knowledge by introducing more mathematics into the economics literature.     

Foreign investment, reparations and the proposal for an international bank: notes on the lectures of J M Keynes in Geneva, July 1929

Keynes's lectures to the Geneva School of International Studiesprovide substance to the intellectual linkages between the Cambridgedon and economists working in international economic agenciesduring the inter-war period. Keynes was keenly sought afteras a policy adviser; as the notes to these lectures indicate,he provided his audience with theoretical insights into thepressing issues of the day - reparations and the transfer problem,the economic foundations of the Dawes and Young Plans, and proposalsfor an international bank.     

The Piketty-Kaldor paradox of growth: Reply to Medlen

Despite the yawning gap between their time horizons, there are a few interesting similarities between Piketty and Keynes. A graph of the Piketty-Kaldor paradox of growth (where a lower growth rate leads to a higher saving rate) is similar to the familiar graph of the Keynesian paradox of thrift (where a lower saving rate leads to higher investment). Keynes showed that cautious spending can lead to recession, and Piketty showed that cautious growth can lead to maldistribution.     

The economics of oil,biofuel and food commodities

We study the effects on the food price of introducing biofuels as a substitute for fossil fuel in the energy market. Energy is supplied by a price-leading oil cartel and a competitive fringe of farmers producing biofuel. Biofuel production shares a finite land resource with food production. A positive relationship results between energy and food prices. We establish that the equilibrium price of food will be growing as long as the oil stock is being depleted, and beyond if demand is growing. An analysis of the effects of the productivity of land use in either the food or the biofuel sectors is carried out. It is shown that, with a highly inelastic demand for food, an increase in the productivity of land in agriculture will decrease the price of food in the short-run, only to increase it in the long-run as the stock of fossil fuel is depleted.
