经济学运用数学的条件

经济学与数学的结合,既给经济学研究带来了巨大的变化与发展,也制造了经济学研究当中的一些误区和陷阱。所以,如何正确地看待经济学研究当中数学的功效,如何正确地运用数学来工具解决经济学问题,就成为当务之急。笔者从经济学运用数学的基本思路入手,抓住经济学运用数学的两个条件,重点分析了经济学与数学在语言上和逻辑上应该满足什么样的条件才能使运用得以实现。我们的分析结果是:经济学与数学在语言上可以自由转换、在逻辑上保持强弱一致,是经济学运用数学的两个必要条件。     

The economist’s oath: a review Essay

George DeMartino’s 2011 monograph, The Economist’s Oath: On the Need for and Content of Professional Economic Ethics, provides an excellent basis for the development of a discourse on the ethics of economists. This review focuses on the way in which mainstream economists’ arguments against consideration of ethics follow from their presentation of economics as a purely technical subject, and the implication that this pretense itself is unethical. The complexity of ethical issues within a pluralist approach to economics is explored, ranging from the institutional environment within which economists practice to epistemological questions.     

Induced innovation and marginal cost of new technology

Lacking data on development and implementation costs for input-saving technologies, we develop a nonparametric procedure to estimate relative differences in marginal technology costs for technical change to be consistent with the induced innovation hypothesis. We apply it to U.S. agriculture.     

Reappraising Austrian Economics' Basic Tenets in the Light of Aristotelian Ideas

This paper sustains that reappraising Austrian economics in the light of Aristotelian ideas is not only possible but also fruitful. First, I draw a sketch of the essential features of Austrian economics. Next, I argue about the necessity for a thorough analysis of the notion of freedom, and I analyze Mises' conception. Next, I expose Aristotle's social, epistemological and economic thought related to Austrian main traits. An account of how the exercise of Aristotelian virtues may be synergic with economic coordination and a sketch of the consequences of the proposal on the teaching of economics are then provided. Finally, the conclusion shortly sums up the content and relevance of Aristotle's contribution.     

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.     

The marginal pricing rule revisited

The purpose of the paper is to introduce a tighter definition for the marginal (cost) pricing rule. By means of an example, we illustrate the improvements that one gets with the new definition with respect to the former one using Clarke’s normal cone, and we discuss its consequences in terms of the existence of equilibria.      

Equity weighting and the marginal damage costs of climate change

Climate change will give rise to different impacts in different countries, and different countries have different levels of development. Equity-weighted estimates of the (marginal) impact of greenhouse gas emissions reflect these differences. This paper analyses the impact of equity weighting on the marginal damage cost of carbon dioxide emissions, and reaches four main conclusions. First, equity-weighted estimates are substantially higher than estimates without equity-weights; equity-weights may even change the sign of the social cost estimates. Second, estimates differ by two orders of magnitude depending on the region to which the equity weights are normalised. Third, equity-weighted estimates are sensitive to the resolution of the impact estimates. Depending on the assumed intra-regional income distribution, estimates may be more than twice as high if national rather than regional impacts are aggregated. Fourth, variations in the assumed inequality aversion have different impacts in different scenarios, not only because different scenarios have different emissions and hence warming, but also because different scenarios have different income differences, different growth rates, and different vulnerabilities.

America’s neglected debt to the Dutch,an institutional perspective

America’s early constitutional development owes a good deal to the experience and policies of the Dutch republic. Many of the parallels are direct: In the late 16th century, the Dutch fought a successful war to secede from a major empire. They wrote a declaration of independence and adopted a federal model of Republican governance almost exactly two hundred years before the Americans. Somewhat later, the Dutch republic and its political institutions subsequently inspired and protected enlightenment scholars. Its leading political family and army played a crucial role in curtailing English absolutism in England and in England’s American colonies, and its federal template provided a model for early American institutions.

Mises’ democracy–dictatorship equivalence theorem: A critique

Ludwig von Mises argues that public opinion, not the form of government, is the ultimate determinant of policy. The implication is that, holding public opinion constant, democracies and dictatorships will have the same policies—a result I call Mises’ Democracy–Dictatorship Equivalence Theorem. According to Mises, dictators have to comply with public opinion or else they will be overthrown. I argue that he seriously overestimates the power of revolution to discipline dictators. Mises was perceptive to note that, in practice, “dictatorially imposed” policies are often democratically sustainable, but he neglected several mechanisms—all more plausible than the threat of revolution—capable of explaining this fact.
