The health gradient among those who are by historical standards both remarkably healthy and well-off is of considerable moral importance with respect to benevolence, justice and the theory of welfare. Indeed it may help us to realize that for most people the good life lies in close and intricate social ties with others which can flourish only when inequalities are limited. The health gradient suggests that there is a story to be told in which egalitarian justice, solidarity, health and well-being go hand-in-hand

In ordinary circumstances, human actions have a myriad of unintended and often unforeseen consequences for the lives of other people. Problems of pollution are serious examples, but spillovers and side effects are the rule, not the exception. Who knows what consequences this essay may have? This essay is concerned with the problems of justice created by spillovers. After characterizing such spillovers more precisely and relating the concept to the economist's notion of an externality, I shall then consider the moral conclusions concerning spillovers that issue from a natural rights perspective and from the perspective of welfare economics supplemented with theories of distributive justice. I shall argue that these perspectives go badly awry in taking spillovers to be the exception rather than the rule in human interactions. I. Externalities Economists have discussed spillovers under the heading of “externalities.” To say this is not very helpful, since there is so much disagreement concerning both the definition and significance of externalities.

People have thought about economics for as long as they have thought about how to manage their households, and indeed Aristotle assimilated the study of the economic affairs of a city to the study of the management of a household. During the two millennia between Aristotle and Adam Smith, one finds reflections concerning economic problems mainly in the context of discussions of moral or policy questions. For example, scholastic philosophers commented on money and interest in inquiries concerning the justice of "usury" (charging interest on money loans), and in the 17th century, there was a great deal of discussion of policy concerning foreign trade. Economics only emerged as a distinct field of study with the bold 18th-century idea that there were "economies"--that is autonomous law-governed systems of human interaction involving production, distribution and exchange. This view is already well developed in Adam Smith's Wealth of Nations, from which much of economics derives.

This paper is concerned with the puzzling divorce that exists between writing on economic methodology and work by philosophers of science. After documenting the extent and nature of the separation and making some disparaging comments about the quality of much of the literature on economic methodology, this essay argues that the divorce results from the differences between the aims of philosophers of science, who are concerned to learn about knowledge acquisition in disciplines such as economics, and the more immediately practical aims of writers on economic methodology, who want to improve the practice of economics. Even with the transcendence of logical positivism or logical empiricism, this separation should persist, although communication between philosophers and eonomists should improve and collaboration increase.

Abstract Contrary to Peter J. Boettke's essay, ?What Went Wrong with Economics??, there is no connection between ?formalism? and the alleged inability of mainstream economists to regard theoretical models as anything other than either depictions of real market economies or bases for criticizing market economies and justifying government intervention. Although Boettke's criticisms of the excesses of formalism are justified, Austrian economists such as Boettke need to justify their view that government interventions into economic affairs are inevitably harmful.

This essay develops an account of health, the functional efficiency theory, which derives from Christopher Boorse's biostatistical theory. Like the BST, the functional efficiency theory is a nonevaluative view of health, but unlike the BST, it argues that the fundamental theoretical task is to distinguish levels of efficiency with which the parts and processes within organisms and within systems within organisms function. Which of these to label as healthy or pathological is of secondary importance. Because the statistical distributions that Boorse's account relies on are distributions of functional efficiency, the functional efficiency theory arguably complements rather than challenges the BST.

People condemn inequalities for many reasons. For example, many who have no concern with distribution per se criticize inequalities in health care, because these inequalities lessen the benefits provided by the resources that are devoted to health care. Others who place no intrinsic value on distribution believe that a just society must show a special concern for those who are worst off. Some people, on the other hand, do place an intrinsic value on equality of distribution, regardless of its contribution to other goals. Derek Parfit and Larry Temkin call these people "egalitarians." I shall always employ quotation marks when referring to "egalitarians" in this special sense, because, as I shall argue, this terminology is misleading. One of its unhappy implications is that almost all egalitarians are not "egalitarians."

Samuel Bowles and Herbert Gintis want to redirect egalitarianism away from redistribution of income and toward redistribution of assets, particularly productive assets. <1> Their main reason, apart from the fact that income redistribution is so obviously dead in the political waters, is that income redistribution lowers productivity and competitiveness, while asset redistribution raises these, and in the long run the welfare of the worst-off depends more on increasing productivity than it does on distribution. Compound interest is a wonderful thing. Young workers in an inegalitarian society growing at 5% per year making half the wages of those in an egalitarian society growing at 1/2% per year will catch up in 16 years and by the time of their retirement will have four times the income. Bowles and Gintis argue that such mathematics, which has long been an argument for inegalitarian trickle-down policies, in fact supports egalitarian asset redistributions.

The Inexact and Separate Science of Economics offers an overview of standard microeconomics and general equilibrium theory. These are not the whole of orthodox economics, and orthodox economics is not the whole of economics. But orthodox economics dominates the profession, and the theoretical core of microeconomics and general equilibrium theory – what I called ‘equilibrium theory’ – is central to most orthodox economics. Unlike many methodological works, which focus almost exclusively on the empirical problems of equilibrium theory and its applications, ISSE is also concerned with the structure, strategy and heuristics of equilibrium theorizing, and it attempts to link questions about theory appraisal to questions about structure and strategy. It is addressed both to philosophers interested in epistemological questions posed by the social sciences and to economists interested in reflecting on and improving their discipline. Its inspiration lies in the work of John Stuart Mill.
