This paper develops the notion of parallel-neutral technical change for inputs and outputs. It is shown that parallel-neutral
technical change generalizes existing radial notions of neutral technical change. A taxonomy of the structural consequences
of parallel-neutral technical change is developed. 相似文献

Green net national product was thought to be one way of measuring sustainable income. However, David Pearce understood that
a better measure of sustainable development was to look at what a generation is leaving in form of capital assets to later
generations. In this article, his arguments and insights are highlighted against recent theoretical advances. 相似文献

We construct a laboratory market in which there is a friction in the matching between buyers and sellers. Sellers simultaneously post prices and then buyers simultaneously choose a seller. If more than one buyer chooses the same seller, the seller's single unit is randomly sold to one of them. Our results show a broad consistency with theoretical predictions, although price dispersion exists and is slow to decay. Prices also exceed the equilibrium level when there are only two sellers, and buyers' purchase probabilities are insufficiently responsive to price differences when there are two sellers. 相似文献

A bstract . In the eyes of European scholars, publicists and politicians who studied Henry George's work, he, as a social philosopher , had adopted the position of the natural law philosophers of the 18th century. The latter inspired the Declaration of Independence, the U.S. Constitution and its Bill of Rights, as well as the poiitical philosophy of Jeffersonian democracy , the ethos of the 18th and 19th century pioneer settlers. George rejected Social Darwinism. He saw natural law as the only true and reliable basis for a just social order. Like Karl Marx he mastered Ricardian economics ; unlike Marx, George made two factors the basis of his system, labor and land. George saw that each person had a natural right —and a natural imperative for survival —to apply his or her productive capacity to the earth –as living space and as storehouse of nutrients and raw materials. The person-land relationship , he discovered, lay at the basis of human culture. And so the land's rent , now monopolized by the few, had to be appropriated to meet the needs of society, most efficiently and justly by a land value tax. 相似文献

Theory and Application of Directional Distance Functions 总被引:4,自引:1,他引:4
In 1957 Farrell demonstrated how cost inefficiency could be decomposed into two mutually exclusive and exhaustive components: technical and allocative inefficiency. This result is consequence of the fact that—as shown by Shephard—the cost function and the input distance function (the reciprocal of Farrell's technical efficiency measure) are dual to each other. Similarly, the revenue function and the output distance function are dual providing the basis for the decomposition of revenue inefficiency into technical and allocative components (see for example, Färe, Grosskopf and Lovell (1994)). Here we extend those results to include the directional distance function and its dual, the profit function. This provides the basis for defining and decomposing profit efficiency. As we show, the output and input distance functions (reciprocals of Farrell efficiency measures) are special cases of the directional distance function. We also show how to use the directional distance function as a tool for measuring capacity utilization using DEA type techniques. 相似文献

A dual representation of a technology, e.g., a cost function, may not contain all of the technological information, but it will contain all of the information about input vectors that would be chosen by a cost-minimizing firm. At least this much is clear for deterministic technologies. The main question addressed in this paper is whether the same can be said about stochastic technologies and their dual representations. Despite some pessimism expressed in the stochastic frontier literature on this question, we argue that there is no extra cost imposed in the stochastic case. Thus, the conclusion of this paper is: Just dual it! 相似文献

Abstract . Henry George's influence was greater in the United Kingdom than in the United States. The 80s and 90s there were particularly favorable for the reception of his revolutionary ideas. Though, thanks to such thinkers as Alfred Russell Wallace and James and John Stuart Mill, a land reform movement already existed, its sudden rise to national significance was due to George. George's writing and speaking skills and his dedication moved many serious citizens into the political Left and heavily influenced men and women who became leaders of British non-Marxian socialism, at the formation and consolidation of their movement. While George's followers broke with both the Wallace and socialist movements, George's rhetorical talents awakened the broad circles of thinking people to a consciousness of the full range of the social question. 相似文献

It has been argued that fundamentally different methodological approaches have made for ‘two sociologies’. This view has obscured the fact that the problem of validity has to be tackled independently of any specific methodological premises because of the textuality of sociological data. This does not necessarily imply, however, a single, unified strategy for validity testing. In this paper, some basic theoretical presuppositions underlying the approach to validity testing in quantitative research will be contrasted with the strategies offered by Max Weber's methodological writings on the ideal type. It is argued that the use of ideal typical constructs in qualitative research (exemplified by patient's illness careers) allows systematic validity testing despite the important differences in the conceptualization of social reality which is used in quantitative research, thus serving the purpose of any empirical sociological research, that is, to gain valid insight into societies' concrete reality. 相似文献

This paper considers why firms differ in the degree to which they rely on their internal R&D organization for generating new technologies (induced innovations) rather than on existing external technology markets (purchased innovations). An empirical model is suggested to explan inter-firm differences in the percentage of new technology induced through R&D efforts. The analysis suggests that such differences are systematically related to the firm's size, its competative environment, and its degree of diversification. 相似文献
