  • The Compatibility of Marxian and Keynesian Economics: a Critical Assessment of Two Interpretations of Marx
    NSER 5(1)—Articles The Compatibility of Marxian and Keynesian Economics: A Critical Assessment of Two Interpretations of Marx By Christian Schoder* This paper contrasts two converse interpretations of Marx which are assessed regarding their compatibility with Keynesian concepts of effective demand, independent investment and endogenous money. On the one hand, the orthodox interpretation abstracts from money and assumes the validity of Say's law. Effective demand does not play a role. It is drawn from Marx's treatment of the general law of capitalist accumulation and the law of the tendency for the rate of profit to fall. On the other hand, the monetary interpretation highly regards of demand, investment and money. Money is the trigger of a general glut as it allows for the separation of purchase and sale as a means of circulation. As a means of payment, money implies its endogenous creation through lending. It is laid out in Marx's treatment of the reproduction and circulation of the aggregate social capital, his analysis of money and credit and his rejection of Say's law. * New School for Social Research. 6 East 16 Street, New York, NY 10003 (e-mail: [email protected]). 17 The Compatibility of Marxian and Keynesian Economics 1. Introduction Various methodological, epistemological and theoretical discrepancies among the variety of schools of thought offer pluralism, but impede the emergence of a common research program (cf. Harvey and Garnett 2008). Hence, there have been several endeavors aimed at integrating Marxian and Keynesian approaches by trying to find shared principles and overcome disparities.i This paper seeks to contribute to this integration process of Marxian and Keynesian ideas.

I survey the literature, covering the time-series and cross-sectional facts, the equity premium, consumption-based models, general equilibrium models, and labor income/idiosyncratic risk approaches.

Abstract This paper uses a model of boundedly rational learning to account for the observations of recurrent hyperin‡ations in the last decade. We study a standard monetary model where the fully rational expectations assumption is replaced by a formal de…nition of quasi-rational learning. The model under learning is able to match remarkably well some crucial stylized facts observed during the recurrent hyperin‡ations experienced by several countries in the 80’s. We argue that, despite being a small departure from rational expec- tations, quasi-rational learning does not preclude falsi…ability of the model and it does not violate reasonable rationality requirements. Keywords: Hyperin‡ations, convertibility, stabilization plans, quasi-rationality. JEL classi…cation: D83, E17, E31. 1 Introduction The goal of this paper is to develop a model that accounts for the main fea- tures of the hyperin°ations of last decade and to study the policy recomen- dations that arise from it.

  • Neoliberalism and Regional Development in Latin America
    Neoliberalism and Regional Development in Latin America Robert N.Gwynne School of Geography University of Birmingham Edgbaston Birmingham B15 2TT Abstract This paper is an attempt to promote discussion on the contemporary relationship between the adoption of neoliberal policies by many Latin American governments and the social and economic development of space within those countries. The shift towards neoliberal policies in Latin America is also associated with increasing economic integration between countries but this topic is not the priority in this paper. Rather the emphasis is to see if any generalizations can be made on how the productive response to neoliberalism is taking place within the regions of Latin American countries. After brief discussions on the political economy and origins of neoliberalism, the paper seeks to examine some broad themes of the political economy of regional development within Latin America. Issues of regional production have very much focused on the growth of non-traditional exports. It is argued that these can be best divided into two groups - those based on manufacturing products and those based on renewable resources. This paper pursues analysis of the latter category, mainly in relation to regional development in Chile - first in relation to the wide range of primary exports and then more specifically in terms of the impact of agricultural export growth on regional land and labour markets. Brief Perspectives on the political economy of neoliberalism The political economy of Latin American countries seems increasingly characterized by neoliberal approaches. The use of the term neoliberal has numerous problems in terms of its ideological connotations. For example in international policy circles, the term Washington consensus (Williamson, 1990) tends to be used, indicating virtually the same package of reforms.

The Market Structure of Higher Learning Abstract A student embarking on a college search is astounded at the number of higher learning institutions available -- an initial response may be to consider their market structure as one of perfect competition. Upon fkrther consideration, though, one sees this is inaccurate. In fact, the market structure of higher learning incorporates elements of monopolistic competition, oligopoly, and monopoly. An institution may not explicitly be a profit maximizer. However, treating it as such allows predictions of actions to be made by applying the above three market structures.

  • Socialism in Europe and the Russian Revolution India and the Contemporary World Society Ofthefuture
    Socialism in Europe and II the Russian Revolution Chapter 1 The Age of Social Change In the previous chapter you read about the powerful ideas of freedom and equality that circulated in Europe after the French Revolution. The French Revolution opened up the possibility of creating a dramatic change in the way in which society was structured. As you have read, before the eighteenth century society was broadly divided into estates and orders and it was the aristocracy and church which controlled economic and social power. Suddenly, after the revolution, it seemed possible to change this. In many parts of the world including Europe and Asia, new ideas about individual rights and who olution controlled social power began to be discussed. In India, Raja v Rammohan Roy and Derozio talked of the significance of the French Revolution, and many others debated the ideas of post-revolutionary Europe. The developments in the colonies, in turn, reshaped these ideas of societal change. ian Re ss Not everyone in Europe, however, wanted a complete transformation of society. Responses varied from those who accepted that some change was necessary but wished for a gradual shift, to those who wanted to restructure society radically. Some were ‘conservatives’, others were ‘liberals’ or ‘radicals’. What did these terms really mean in the context of the time? What separated these strands of politics and what linked them together? We must remember that these terms do not mean the same thing in all contexts or at all times. We will look briefly at some of the important political traditions of the nineteenth century, and see how they influenced change.

  • Product Differentiation
    Product differentiation Industrial Organization Bernard Caillaud Master APE - Paris School of Economics September 22, 2016 Bernard Caillaud Product differentiation Motivation The Bertrand paradox relies on the fact buyers choose the cheap- est firm, even for very small price differences. In practice, some buyers may continue to buy from the most expensive firms because they have an intrinsic preference for the product sold by that firm: Notion of differentiation. Indeed, assuming an homogeneous product is not realistic: rarely exist two identical goods in this sense For objective reasons: products differ in their physical char- acteristics, in their design, ... For subjective reasons: even when physical differences are hard to see for consumers, branding may well make two prod- ucts appear differently in the consumers' eyes Bernard Caillaud Product differentiation Motivation Differentiation among products is above all a property of con- sumers' preferences: Taste for diversity Heterogeneity of consumers' taste But it has major consequences in terms of imperfectly competi- tive behavior: so, the analysis of differentiation allows for a richer discussion and comparison of price competition models vs quan- tity competition models. Also related to the practical question (for competition authori- ties) of market definition: set of goods highly substitutable among themselves and poorly substitutable with goods outside this set Bernard Caillaud Product differentiation Motivation Firms have in general an incentive to affect the degree of differ- entiation of their products compared to rivals'. Hence, differen- tiation is related to other aspects of firms’ strategies. Choice of products: firms choose how to differentiate from rivals, this impacts the type of products that they choose to offer and the diversity of products that consumers face.

  • History in the Study of Industrial Organization
    History in the Study of Industrial Organization David Genesove Hebrew University of Jerusalem and C.E.P.R. May 13 2016 Preliminary Draft *I am grateful for comments by discussants Konrad Stahl, Chaim Fershtman, John Sutton and Bob Feinberg, and others in presentations at the 2012 Nordic IO Conference, the IDC, Herzlya, the MAACI Summer Institute on Competition Policy, Israel IO Day and the 2015 EARIE Conference. I. Introduction In studying Industrial Organization, economists have at times turned to the past to illustrate and test its theories. This includes some of the seminal papers of the new empiricism (e.g., Porter, 1983). This readiness to cull from the historical record has neither been examined critically, nor accompanied by much of an attempt to follow the industrial organization of markets over time. This paper asks how history can help us understand markets, by posing the following dual questions: (a) what are the advantages and disadvantages of using old markets to illuminate our understanding of current ones, and (b) is a historical approach to the study of Industrial Organization possible and worth pursuing? We are talking about history in two different ways: as the past, and as an analytical approach. History as the past means using old markets in empirical work in the same way one uses contemporary markets, whether that is inductively learning about markets in the “theory-development role of applied econometrics” (Morgan, cited by Snooks, 1993), estimating parameters of interest, or “using historical episodes to test economic models for their generality” (Kindleberger, 1990, p. 3). History as an analytic approach means describing a sequence of events as a logical progression informed by economic theory but unencumbered by it, with room for personalities and errors, and perhaps emphasis on certain events with overwhelming importance.
