瓦尔拉斯新古典一般均衡体系质疑

通过对瓦尔拉斯一般均衡体系由简单的生产交换经济到扩大的包含资本形成方程在内的经济体系的分析,指出一直标榜为现代主流新古典理论支柱之一的瓦尔拉斯一般均衡体系内部存在着一系列逻辑矛盾,从而表明它描述的只是一种差别利息率下的实物经济一般均衡,而并不是现实资本主义经济关系下为获取统一利润率竞争的货币经济均衡。     

Making green discourses matter in policy-making: Learning from discursive power struggles within the policy area of car taxation

This paper is about stability and change in the policy-making discourse of a traditional neoclassical policy area, the area of car taxation. Stability is here related to the unquestioned continuation of a traditional neoclassical economics perspective in policy-making, whereas change is related to the introduction and impact of environmental concerns. The aim of the paper is to investigate, what makes green discourses matter in traditional policy-making. It is based on an in-depth study of policy-making processes related to car taxation in two environmental front-runner countries, Sweden and Denmark.Making green discourses matter in policy-making is an important contemporary environmental challenge. Therefore, as Tian Shi argues, we need more research into the institutional setting of the policy-making process. Ecological economics as a policy science has to have a broad understanding of the political economic nature of the policy process. Taking this standpoint as the point of departure, the paper seeks to uncover questions such as, what is the policy-making reality in which Swedish and Danish green discourses have to make a difference? How do existing neoclassical regimes react, when green actors attempt to influence policy-making from an environmental point of view? And to what extent can green discourses actually have an impact on the policy world within the area of car taxation?The paper concludes that the traditional neoclassical economic discourse is particularly robust and resistant against alternative green discourses. Stability rather than change is the dominating picture. This does not imply that environmental concerns will not be taken into account in the future. Rather it implies that only the changes, which keep up the existing order, or enhance the narrow power-related interests of the dominating actors, will materialise more or less easily. The rest is a power struggle in which timing, coalition-building, persistence and thorough knowledge about the field in question is of importance. In this struggle change agents will also benefit from the ability to rethink dominating ways of thinking and doing in an environmentally benign way. A rethinking that is based on environmental values while at the same time holding positive visions that are ‘compatible’ with the existing dominating discourse.     

A neoclassical interpretation of momentum

The neoclassical theory of investment implies that expected stock returns are tied with the expected marginal benefit of investment divided by the marginal cost of investment. Winners have higher expected growth and expected marginal productivity (two major components of the marginal benefit of investment), and earn higher expected stock returns than losers. The investment model succeeds in capturing average momentum profits, reversal of momentum in long horizons, long-run risks in momentum, and the interaction of momentum with several firm characteristics. However, the model fails to reproduce the procyclicality of momentum as well as its negative interaction with book-to-market equity.     

Aid allocation rules

This paper studies an aid allocation rule used by major development agencies, and investigates optimal allocations when recipients are neoclassical economies undergoing transition dynamics. When recipients face aid absorption constraints, allocations that favor poorer recipients are not always optimal, contrary to what is assumed in assessments of donor performance. The most quantitatively significant factors that determine the optimal sensitivity to recipient characteristics are the generosity of the aid budget and the extent of absorption constraints. In neoclassical recipients, aid can only accelerate growth where there is already growth, so the optimal rule places little weight on growth and optimality is largely a matter of balancing recipient need against absorption constraints.     

Specialization dynamics

This paper proposes a new empirical framework for analyzing specialization dynamics. A country’s pattern of specialization is viewed as a distribution across sectors, and statistical techniques for analyzing the evolution of this entire distribution are employed. The empirical framework is implemented using data on 20 industries in seven OECD countries since 1970. We find substantial mobility in patterns of specialization. Over time horizons of 5 years, this is largely explained by forces common across countries, including world prices and common changes in technical efficiency. Over longer time horizons, country-specific changes in factor endowments become more important. There is no evidence of an increase in countries’ overall degree of specialization.     

Three macroeconomic syntheses of vintage 1937: Hicks,Haberler, and Lundberg

Abstract

The 1920s and 1930s were years of intensive debate about economic dynamics and stabilisation policies. There was a large variety of explanations of cycles and depressions, and Keynes’ General Theory of Employment, Interest and Money (1936) was pitched against them. In 1937, followed three different attempts to provide synthetic expositions of macroeconomic theory that would deal with the Keynesian challenge: Hicks’ Mr. Keynes and the “Classics”, Haberler's Prosperity and Depression, and Lundberg's Studies in the Theory of Economic Expansion. This paper compares those 1937 syntheses and contrasts them with the “Neoclassical Synthesis” and the current “New Neoclassical Synthesis”.     

Some Reflections on the Spatial Dimensions of Occupational Segregation

This paper considers the role that urban spatial structure may play in the process of occupational segregation, and argues that neoclassical economic models of urban employment and residential location decisions have not considered the relationship between gender-based labor market status and space. The paper provides a critical feminist perspective on how conventional urban models have been used to explain patterns of segregation, and suggests reasons for limitations in existing theoretical and empirical analysis. It also explores ways in which economists can draw on work in other disciplines to develop fuller and more useful models of the relationship between urban spatial structure and occupational segregation.     

A Socio-instutionalist Critique of the 1990s' Reforms of the United Kingdom's National Health Service

This paper argues that the on-going reforms to the UK's National Health Service initiated in the 1990s represent potentially profound institutional change to the values underpinning the process of care. The market-orientation of the reforms is highlighted, and it is asserted that the theoretical rationale for this is informed by the nascent neoclassical health economics and new institutionalist literatures, which exhibit utilitarian propensities in that both stress outcomes and at best relegate process. Drawing from the seminal contribution of Thorstein Veblen, the paper argues that market-oriented reform in the UK may induce a shift from a Hippocratic ethos to a more individualistic value system.     

发展经济学经济发展思想三种思路的比较分析

发展经济学自诞生以来 ,其经济发展思想基本上有结构主义、新古典主义、新古典政治经济学这三种基本思路。通过其理论特征和实践战略的比较分析 ,结构主义在实践中表现为唯资本论、唯计划论和唯工业化论 ;新古典主义主要强调微观经济基础、市场机制和资源配置效率的重要性 ;而新古典政治经济学却认为制度是内生的 ,制度结构和非经济因素对资源配置和经济发展的影响显著 ,强调技术内生化、边干边学、知识外溢、劳动分工和政府作用的内生性 ,而且提倡可持续发展是一种科学的发展观 ,是发展经济学的新发展。     

Steady-state growth and the elasticity of substitution

In a neoclassical economy with endogenous capital- and labor-augmenting technical change the steady-state growth rate of output per worker is shown to increase in the elasticity of substitution between capital and labor. This confirms the assessment of Klump and de La Grandville (2000) that a greater elasticity of substitution allows for faster of economic growth. However, unlike their findings my result applies to the steady-state growth rate. Moreover, it does not hinge on particular assumptions on how aggregate savings come about. It holds for any household sector allowing savings to grow at the same rate as aggregate output.
