Critical realism and Kantian transcendental arguments

Tony Lawson has made use of transcendental arguments, as developedby Roy Bhaskar, to criticise mainstream economics. This importationof Kantian ideas into economic methodology is commendable, sincethey offer the best means available for diagnosing and overcomingthe empiricism that underlies mainstream economics. This paperargues, however, that instead of using Bhaskar's transcendentalarguments, critical realists would do better to employ Kant'sown, which are of direct relevance to economic methodology andhave greater persuasive force than Bhaskar's.     

Entrepreneurs drive community revival in the wake of disaster

This article responds to the points raised by Daniel P. Aldrich, Emily Chamlee-Wright, and Lori Peek in the symposium on our book Community Revival in the Wake of Disaster: Lessons in Local Entrepreneurship (Palgrave Macmillan, 2015).     

Historical reference: Hume and critical realism

The purpose of this paper is to make the case for discussingdevelopments in the history of thought as having the potentialto inform modern discussion. The case is made by means of consideringthe particular relevance of David Hume's thought for criticalrealism, emphasising his use of the concepts of belief and imaginationboth in establishing philosophical foundations and as beingrelevant for theory content. The notion that context is significantis used constructively by suggesting that important elementsin common between the contexts of Hume and of modern discussionsreinforce the potential value of considering Hume's ideas.     

Schumpeter and the revival of evolutionary economics: an appraisal of the literature

During the last two decades we have seen a revival of interest in the works of Joseph Schumpeter and “evolutionary” ideas in economics more generally. A professional society honouring Schumpeter's name has been founded, and linked to it we have had for more than fifteen years now a professional journal devoted to this stream of thought. However, it has been argued that, despite these developments, the link between Schumpeter's own work and the more recent contributions to evolutionary economics is in fact rather weak. This paper considers this claim. Based on an analysis of Schumpeter's contribution to economics the paper presents an overview and assessment of the more recent literature in this area. It is argued that although there are important differences between Schumpeter's work and some of the more recent contributions, there nevertheless remains a strong common core that clearly distinguishes the evolutionary stream from other approaches (such as, for instance, so-called “new growth theory”). RID="*" ID="*" Many people have contributed to this paper in various ways. Jon Hekland at the Norwegian Research Council started it all by asking me to make an overview of the contribution from “evolutionary economics” to our understanding of contemporary economies. Several people helped me on the way by supplying written material, comments and suggestions, and I am indebted to all of them. Brian Arthur, Stan Metcalfe, Keith Pavitt, Erik Reinert, Paolo Saviotti and Bart Verspagen may be particularly mentioned. A preliminary version was presented at the conference “Industrial R&D and Innovation Policy Learning – Evolutionary Perspectives and New Methods for Impact Assessment” organised by the Norwegian Research Council (“SAKI”) at Leangkollen, Asker, April 18–19.2002. I wish to thank the discussant, Tor Jakob Klette, and the participants at the conference for useful feedback. Moreover I have benefited from comments and suggestions from the editors and referees of this journal. The final responsibility is mine, however. Economic support from the Norwegian Research Council (“SAKI”) is gratefully acknowledged.     

Persistent demi-regs and robust tendencies: critical realism and the Singer-Prebisch Thesis

Debate about whether the terms of trade for primary productsrelative to manufactures have a tendency to deteriorate hasbeen ongoing for half a century. The phenomenon itself providesan example of a persistent contrastive demi-regularity. Thisis viewed as the result of a robust tendency, understood asan enduring and pervasive characteristic effect generated bya powerful and stable underlying causal mechanism. On this basis,the key problem for primary products lies in the biologicallimits on consumption, to which may be added capitalism-specifictendencies affecting processes of production and distribution.The paper concludes by arguing that the relevant holistic generictendency under capitalism involves a long-term contraction inthe primary product share of world trade.     

Economics and Reality: A philosophical critique of transcendental realism

In Economics and Reality Tony Lawson seeks to criticise and offer an alternative to mainstream economic theorising. The book draws upon the work of Bhaskar, advocating a form of realism termed transcendental realism, in opposition to the empirical realism taken to underpin mainstream theorising. However, the specific objections advanced by Lawson against empirical realism are frequently confused and confusing. Lawson's own appeal to structures suffers from lack of definition, and empirical realism seems more applicable to Keynesian, not mainstream, economics. The claim that the social sciences can be modelled on the natural sciences is not particularly illuminating.     

On some criticisms of critical realism in economics

Methodological comments on critical realism in economics haveproliferated over the past decade—typically focusing onTony Lawson's Economics and Reality and Reorienting Economics,which constitute the core of this project. In the present paperwe select a series of important, mostly very recent argumentsagainst critical realism in economics and assess their meritsand demerits.     

Some problems with the conception of the human subject in critical realism

The human subject plays a central role in the theory of socialreality developed by Tony Lawson in his book Economics and Reality.This theory relies on an account of human cognitive functioningthat distinguishes discursive from tacit knowledge. The presentpaper argues that Lawson's discussion of tacit knowledge inEconomics and Reality is underdeveloped in that it leaves unexploredthe notion of internalised knowledge. John Searle's work onmind, intentionality and the Background is reviewed and proposedas a solution to this problem.     

Economics, realism and reality: a comparison of Maki and Lawson

There is presently considerable debate about the applicationand interpretation of realism in economics. Interest in thisarea of the philosophy and methodology of economics has intensifiedover the last twenty years, especially owing to the substantialcontributions by Uskali Mäki and Tony Lawson, respectively.Although their work falls under the same banner of realism ineconomics, their projects differ significantly in many importantrespects. This review tries to clarify the contrasting approachesof each author and explains the main reasons for the differencesbetween them. The emphasis is on clarification of their respectivepositions rather than a comprehensive critical evaluation assuch.     

社会保障的新理念与中国农民扶持性社会保障体制

中国的市场化改革使广大的中国农民直接暴露在现代市场经济风险下,而家庭联产承包制的实施又使改革开放前与计划经济体制相适应的保障体制无法运转,这样,中国广大农民成为了现代市场经济中最没有保障的弱势群体。因此,建立农民社会保障体系的意义重大。中国农民社会保障体制迟迟没有建立的原因有二:其一,传统社会保障理念仅考虑到其工具价值,忽视了其目的价值;其二,农民的组织化程度低,导致他们在社会利益分割过程中没有谈判地位。从建立农民社会保障体制的双重价值出发,建立保障农民生存权和基本发展权的农民扶持性社会保障体制具有重要意义。     

The monetary appreciation of paintings: from realism to Magritte

This study investigates how investments in paintings comparewith those in stocks in terms of risk–return trade-offusing Sharpe and Treynor ratios and Markowitz efficient frontiers.A large database was analysed consisting of more than 10,500auction prices of Belgian paintings over the period 1970–97.These paintings are the auctioned oeuvre of 71 internationallyrecognised painters representing the main artistic schools (fromsocial realism to surrealism) over the period 1850–1950.Hedonic art returns are corrected for auction location and auctionhouse, artistic school, painters' reputation, medium, signatureand painting size. Surrealism and luminism have been the mostpopular currents of art (in monetary terms), while expressionismand symbolism have gained (financial) esteem. This study concludesthat art investments underperform equity market investmentsowing to the high risk of investing in art and its high transactioncosts, resale rights and insurance premia. In addition, theMarkowitz efficient frontier shows limited diversification potentialfor art.

Storage and security of supply in the medium run

This paper analyzes the role of private storage in a market for a commodity (e.g. natural gas) whose supply is subject to the threat of an irreversible disruption. We focus on the medium term in which seasonality of demand and exhaustibility can be neglected. We characterize the price and inventory dynamics (accumulation, drainage and limit stocks) in a competitive equilibrium with rational expectations. We show the robustness of our results to alternative scenarios in which either a disruption has finite duration or the crisis is foreseen. During the crisis consumers may put pressure on the Government to intervene, but too severe antispeculative measures would inefficiently discourage storage. Practical solutions to this dilemma cause welfare losses that we characterize and quantify.     

On the interaction between education and social security

This paper uses an overlapping generations model with endogenous fertility choices to analyze the quantitative costs and benefits of subsidizing higher education, paying particular attention to the interaction between such policy and the sustainability of the social security system. The paper focuses on the demographic change as the mechanism that link both policies. It is found that an increase in education subsidies changes the educational composition of the population and lowers average fertility. Lower average fertility and higher life expectancy of educated individuals translates into changes in the age structure of the population that requires an increase in the social security tax rate in order to balance the pension budget. Such process reduces the welfare benefits of this educational policy since the rise in social security taxes lowers the after-tax lifetime earnings of almost all individuals born in the period of the policy reform and over.     

Economics as progress: the LSE approach to econometric modelling and critical realism as programmes for research

In the face of claims that economics is increasingly drivenmerely by fashion, this paper draws out certain similaritiesand differences between two self-consciously progressive anddevelopmental research programmes—namely the LSE approachto econometric modelling and critical realism in economics.The argument is that, while these two programmes of researchshare a common point of departure and possess many common elements,what at root distinguishes them is their adoption of opposingphilosophical orientations. The comparison enables both thenature of each programme, and the relevance of their commonconcerns, to be more easily appreciated and helps clarify thesort of evidence that would provide a basis for selecting oneproject over the other.     

Social security and unsecured debt

In this paper, we use a calibrated life-cycle model to explore quantitatively ways of reducing the burden of social security in a world populated by both optimizing and rule-of-thumb consumers. Social security contributions force young households with upward-sloping income profiles to save a sizeable portion of their income for retirement, when their optimal consumption plan would likely have them either saving little or borrowing. We first use household data to document that young households have accumulated social security contributions that are large relative to debt holdings. Then, using a calibrated life-cycle model, we show that both allowing households to use social security wealth to pay off their debt and exempting young households from social security contributions (but in both cases requiring higher contributions later) mitigate many of the inefficiencies of social security from the perspective of life-cycle financial planning. Specifically, in our preferred experiment, which exempts households whose heads are under 30 from making social security contributions, we find that certainty-equivalent consumption increases by 3.4% for optimizing households and by 3.3% for rule-of-thumb households.     

Social security and economic integration

This letter analyzes the impact of economic integration on capital accumulation and capital flows when countries differ in their social security systems. Funding and early retirement both foster capital accumulation relative to pay-as-you-go pensions with flexible retirement. When economies integrate, both imply capital outflow possibly resulting in utility losses.     

信息不对称与医疗保险

本文运用经济学信息学对称理论分析医疗保险市场的运行情况,首先探讨医疗保险市场的特殊性,认为在私人医疗保险市场上,逆向选择和道德风险将导致低效率,从而为公共卷入提供了效率方面的理论根据;社会医疗保险虽然一定程度上克服了逆向选择,但却由于第三方支付等原因而无法克服道德风险,因此无法解决其医疗费用膨胀等财政问题;进而分析了公共、私人以及二者混合等医疗保险供给的效率,并进行了比较,探讨了医疗保险改革在理论层面的现状和发展趋势。最后对社会医疗保险制度评价体系的最新动态和成果做了评介。     

Social security and risk sharing

In this paper we identify conditions under which the introduction of a pay-as-you-go social security system is ex ante Pareto-improving in a stochastic OLG economy with capital accumulation and land. We argue that these conditions are consistent with realistic specifications of the parameters of the economy. In our model financial markets are complete and competitive equilibria interim Pareto efficient. Therefore, a welfare improvement can only be obtained if agents? welfare is evaluated ex ante, and arises from an improvement in intergenerational risk sharing. We also examine the optimal size of a given social security system as well as its optimal reform.     

Social security and intergenerational equity

This paper considers the implications of social security for intergenerational equity. It shows that a balanced-budget unfunded system can be optimal even in a dynamically efficient economy without uncertainty and externalities. The relevant criteria for the optimality of the public transfer program are equity among generations and time consistency. The scheme can survive adverse shocks if the well-being of the elderly at each point in time is sufficiently valued.
