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.

Economists, value judgments, and climate change: A view from feminist economics

A number of recent discussions about ethical issues in climate change, as engaged in by economists, have focused on the value of the parameter representing the rate of time preference within models of optimal growth. This essay examines many economists' antipathy to serious discussion of ethical matters, and suggests that the avoidance of questions of intergenerational equity is related to another set of value judgments concerning the quality and objectivity of economic practice. Using insights from feminist philosophy of science and research on high reliability organizations, this essay argues that a more ethically transparent, real-world-oriented, and flexible economic practice would lead to more reliable and useful knowledge.     

Privatization, productive efficiency and social welfare with a foreign competitor

We investigate how decision-making upon cost-reducing R&D investment by a domestic public firm is affected by privatization and entry of a foreign firm. It is shown that entry of a foreign firm lowers productive efficiency of the domestic public firm but improves the domestic social welfare. It is also shown that privatization of the public firm lowers productive efficiency and deteriorates domestic social welfare.     

Labour markets, social justice and economic efficiency

In conventional economic theory, a trade-off supposedly existsbetween social justice and economic efficiency. In reality,market and other economic institutions are dominated by powerrelations, so that the sponsorship of social justice is a productivefactor. Neo-liberal economic policies, by lifting the constraintson the exercise of unequal power, increased injustice and triggereda downward economic and social spiral. Reversing this requiresa revolution in economic theory and policy focused on full employment,the working of labour markets, the organisation of work, andhousehold organisation, social provision and self-sufficiency.     

Energy efficiency and economic growth of China： 1953-2006

Energy plays an important role in the economic life. With the rapid development of economy, the constraint of energy on the sustainable development of economy is becoming more and more obvious. This paper just Studies the factors influencing energy efficiency of China and the relationship between energy efficiency and China＇s economic： growth. By using time series multivariable linear regression methods with China＇s relevant data from 1953 to 2006, this paper constructs the regression model to analyze the factors that would impact energy, efficiency. After that, a regression model of China＇s real output to capital, labor and energy e lficiency is conducted to estimate the marginal contribution of every factor to the real output to prove the fundamental influence of energy efficiency to the economic growth. In the end, some policies and recommendations are also put forward in order to improve the energy efficiency; of China.     

Oil consumption and economic efficiency: A comparative analysis of advanced, developing and emerging economies

This paper investigates the economic efficiency-oil consumption relationship in 42 countries during the period 1986-2006. In a first stage by using DEA window analysis countries' economic efficiencies are obtained. In a second stage an econometric analysis based on robust GMM estimators reveals an inverted ‘U’-shape relationship between oil consumption and economic efficiency. In order to capture heterogeneities among countries' development stages the analysis has been separated into two groups (advanced economies and developing/emerging economies). The results show that advanced economies have much higher turning points compared to emerging and developing economies. It appears that oil consumption increases countries' economic efficiency. In addition the consumption patterns of oil products and its derivatives have changed through years and among countries. The different turning points from the econometric analysis indicate the dependence of oil consumption in advanced economies (higher turning points) is driven mainly by household purchasing activities and their standards of living (transport, housing and water, food, etc.). Finally, it appears that oil consumption is the main driver behind the progress of industrialization and urbanization regardless of the country's development stage.     

Constitutions and economic reforms in transition: an empirical study

Experiences of countries undergoing post-socialist transition in Central and Eastern Europe, as well as Central and Southwestern Asia, during the last 17 years, reveal great variety in economic reform paths and their successful implementation. At different moments of transition varying constitutional rules have also emerged in these countries. In our empirical study we find a significant relationship between constitutional rules and the economic reform process in post-socialist countries of Europe and Asia after 1989. In principle, the results confirm the arguments of the so-called negative constitutionalists, according to which the main function of the constitution for economic reforms in transition is its functioning as a commitment mechanism. The conclusions constitute an important step towards verification of different and often conflicting theories proposed by constitutional economists and allow to formulate practical recommendations for constitutional legislators and other actors capable of influencing constitutional change in countries encompassed by the study.

An efficiency characterization of plurality social choice on simple preference domains

Summary. We consider a model of social choice dealing with the problem of choosing a subset from a set of objects (e.g. candidate selection, membership, and qualification problems). Agents have trichotomous preferences for which objects are partitioned into three indifference classes, goods, bads, and nulls, or dichotomous preferences for which each object is either a good or a bad. We characterize plurality-like social choice rules on the basis of the three main axioms, known as Pareto efficiency, anonymity, and independence.Received: 29 August 2003, Revised: 3 June 2004, JEL Classification Numbers: D70, D71, D72.Biung-Ghi Ju: I am grateful to William Thomson and Jianbo Zhang for their helpful comments and discussions.

Preference purification and the inner rational agent: a critique of the conventional wisdom of behavioural welfare economics

Neoclassical economics assumes that individuals have stable and context-independent preferences, and uses preference satisfaction as a normative criterion. By calling this assumption into question, behavioural findings cause fundamental problems for normative economics. A common response to these problems is to treat deviations from conventional rational choice theory as mistakes, and to try to reconstruct the preferences that individuals would have acted on, had they reasoned correctly. We argue that this preference purification approach implicitly uses a dualistic model of the human being, in which an inner rational agent is trapped in an outer psychological shell. This model is psychologically and philosophically problematic.     

At the origin of post-war mainstream of economics: On pareto’s influence on economic theory

Allais (1968) maintained that Pareto’s influence on the development of economics was felt only after considerable delay and was confined to Italy and France. This paper provides a reconstruction of the intellectual dissemination of Pareto’s thought through Europe and the United States in the period 1900–1940, showing that it was influential in the period from c.1900 to the mid-1920s and that in the 1930s it was highly important in the foundation of mainstream post-war economic theory, although in a more elusive way than before.(JEL:B13, B16, B21, B23, B31)     

哈耶克诘难、权威转变与经济成长:中国分权式改革的逻辑

中国的分权式改革一定是做对了什么才产生了我们见到的经济奇迹,那是什么呢?中国的分权式改革从事实上回应了哈耶克诘难,即信息和知识的分散性使得计划体制不可能实现其理想状态。通过经济上放权让利和政治上的集权,调动社会各阶层的能动性,使得权威和信息相匹配,形成了有效的层级分工创新体制,从而实现经济成长。由于分工的深化和经济活动的扩展,经济分权体现出必然性。在这一过程中,每一个分立的个体都凭借个体知识在分工体系中分享收益,因而实现了共享式的发展,从自由的角度看,个体的自由也得到了极大的扩展。如果要释放更多的经济增长潜力,进一步的改革是必需的。     

The social efficiency of instruments of promotion of renewable energies: A transaction-cost perspective

This paper compares the social efficiency of the regulatory instruments used to promote renewable energy sources in electricity generation, taking into consideration their role in promoting the preservation of collective goods. They are based on a purchase obligation and act either by price (feed-in tariffs) or by quantity (bidding for new RES-E capacities; RES-E quotas). From the Public Economics perspective, the two instruments are distinct in terms of cost-efficacy and market incentives in a world of imperfect information. Exchangeable quotas of green certificates are preferred because this instrument allows better control over consumer costs and whilst retaining market incentives. Transaction cost economics (TCE) contributes to the assessment of these instruments, by introducing RES-E investment safeguard as a major determinant of social efficiency, and the instruments' conformity to its institutional environment as a determinant of its viability. In light of this additional consideration, the arrangements between RES-E producers and obligated buyers inherent in each instrument are in fact quite similar—either long-term contracting or vertical integration. We compare and assess RES-E price- and quantity-instruments on several dimensions from both the public economics and TCE perspectives: control of the cost for consumers, safeguards of RES-E investments, adaptability of the instrument in order to preserve its stability in the long run, market incentive intensity, and conformity with the new market regime of electricity industry. It shows neither instruments offer an optimal solution in each of these dimensions. The government will thus select an instrument in accordance with the relative importance of its objectives.     

Between a rock and a soft place: Ecological and feminist economics in policy debates

The field of ecological economics includes both economic analysis on the one hand, and discussions of normative values and visions for society, on the other. Using feminist insights into cultural beliefs about the relative “hardness” and “softness” of these two sides, this essay discusses how ecological economists can use this unique “between” space in order to better inform policy. The current crisis of global climate change, it is argued, requires that economists move beyond modeling and measurement, while ecological thinkers need to re-examine beliefs about markets and profit.     

Static efficiency decompositions and capacity utilization: integrating economic and technical capacity notions

Starting from existing static decompositions of overall economic efficiency on nonparametric production and cost frontiers, this article proposes more comprehensive decompositions including several cost-based notions of capacity utilization. Furthermore, in case prices are lacking, we develop additional decompositions of overall technical efficiency integrating a technical concept of capacity utilization. These new efficiency decompositions provide a link between short and long run economic analysis and, in empirical work, avoid conflating inefficiency and differences in capacity utilization. An empirical analysis using a monthly panel of Chilean hydro-electric power plants illustrates the potential of these decomposition proposals.     

Vilfredo pareto and contemporary economics: Social equilibrium, fiscal decentralisation and economic growth

During the second decade of the twentieth century, Vilfredo Pareto’s influence on the fiscal scholarship of Guido Sensini, Gino Borgatta and others in Italy was significant. In the 1920s a unique approach to fiscal thought developed which was grounded in the Paretian notion of social equilibrium. This study highlights the main features of this approach and considers why it went into decline from the 1930s and terminated in the 1950s. The paper also points to a potential benefit from integrating Aldo Scotto’s pioneering work on fiscal decentralisation with the Paretian fiscal thought of Sensini and Borgatta as part of a modern research program on the relationship between fiscal decentralisation and economic growth.

中国经济改革:背景、机制与挑战

经过三十余年的经济改革,中国的经济取得了巨大的进步,中国这条巨龙也正在逐渐回归到她在世界经济中应有的位置。这种经济改革是如何成功的?本文认为,承接于特定的历史经济背景,中国经济中三类主要的行为主体(中央、地方、民众)根据自身的条件进行了事实上的互动式的协调分工,各自对既有的约束条件进行突破,并在互动演进的发展过程中逐步建立了新的规则,这些规则所确立的激励与约束极大地调动了各参与主体的积极性,实现了从事必躬亲到各司其职的职能转换。正是在这些过程中,中国经济逐渐得到发展并获得前所未有的成就。但我们同时强调,在经济改革的过程中,也必须认清体制的不足,积极应对新的挑战。     

The Stories That Economists Tell: Mainstream,Hyman Minsky,and Institutional Views of Consumer Behavior

The financial crisis of 2008 provided an informal test of mainstream and institutional views of consumer behavior. The test posed by the financial crisis assumes the form of a “story.” A successful story provides a reasonably coherent explanation of events, confirming our beliefs and justifying our policies. First, the article examines the failure of mainstream economics to present a coherent story of consumer behavior. Ignoring the relevance of assumptions, as Milton Friedman advocated, leads economists to hypostasize the model, filtering information central to the crisis. Second, Minsky’s discussion of consumer behavior and its effect on cash inflows to businesses represents an institutional explanation regarding why John Maynard Keynes’s long-run vision did not occur. The third section expands on some of the themes addressed by Minsky, which are found among the contributions of institutional economists, focusing on efforts to mold institutions to increase cash inflows to corporations and protect those inflows.     

The efficiency of social public expenditure in European countries: a two-stage analysis

Do European countries differ in the efficiency of their welfare policies? And which factors can account for such variability? To address these questions, we perform a two-stage efficiency analysis. First, based on a composite output indicator for social protection expenditure, we measure efficiency by means of the Free Disposable Hull and Data Envelopment Analysis techniques. Second, we perform an econometric analysis to identify the factors that can be associated to cross-country differences. We find that countries scoring higher efficiency have higher education and GDP levels, a smaller population size, a lower degree of selectivity of their welfare systems and a lower corruption level.     

Family,religion and economic performance: A critique of cultural determinism

Arguing that some attitudes that may constitute an obstacle to the development process are culturally funded, cultural determinism pleads that underdevelopment is essentially generated endogenously, in other words, that people in developing countries, with their beliefs and their attitudes, are the more liable for the poverty in which they live. The simplicity of these arguments has seduced a large number of scholars but what seems to be a cultural brake on economic development could be explained otherwise. This critique of cultural determinism's arguments attempts to supply an alternative version of the interaction of culture and development, from which power, class, domination and the international division of labour will not be excised. In order to simplify this study only two of the cultural features most often referred to will be brought into focus: religion and family and patterns of kinship.
