Abstract . Application of the land value tax has been described for many natural resources. However, the problems encountered with flowing underground resources have not been fully discussed. Groundwater is one such flowing resource that affects the value of surface land. The underground water is also subject to its own market forces. If a Georgist tax is to be applied to groundwater or to land affected by it, the administrator of the tax must consider the interplay that occurs between the two resource markets. A system of separable property rights to the two resources offers the prospect for efficient use. But the monitoring of ground water use must accompany such a separation.  相似文献

This is a reply to Geoffrey Hodgson's Comment on an earlierpaper by Caldwell (Hodgson on Hayek: a critique). Though certainareas of agreement are noted, differences in interpretationconcerning Hayek's views on the Malthus–Darwin relationship,on cultural evolution, on the extent to which Hayek may be characterisedas an ontogenist, and on methodological individualism remain.  相似文献

Three interpretive systems of soil classification for agriculture were compared with respect to land use, crop yields, and certain economic characteristics. Sixty-eight farms in the Peace River area of British Columbia were classified as high or low under the ARDA, soil survey, and agronomic classification systems. Mean values for the two categories of farms under each classification system were computed and tested for statistical significance. The results indicated that as the number of significant differences increased, so did the management consideration. Consequently, the agronomic classification was the best indicator, followed by the ARDA system, and then the soil survey productivity index. Considering the basic concepts of the classification systems, this trend was not entirely unexpected. The results suggest that the management factor should play a larger role in developing viable interpretive soil classification systems and that co-operation should be sought among the various disciplines concerned with agricultural land use. LES FACTEURS SOCIO-ECONOMIQUES DANS LA CLASSIFICATION DES SOLS ACRICOLES – Trois systèmes de classification des sols agricoles ont été comparés avec I'aide du type d'utilisation des sols, du rendement des récoltes et de certaines caractéristiques économiques. Soixante-huit fernws dans la zone de “Peace River” en Colombie Britannique out été classifiés, en deux catégories avec I'aide de I'ARDA de I'enquête des sols et des systèmes de classification agronomique. Les principals valeurs pour les deux catégories de fermes appartenant à chaque système de classification ont été calculées et testées afin de vérifier leur signification statistique. Les résultats indiquérent que le nombre de différences significatives augmentaient en mêmc temps que la qualityé du “management”: Conséquence directe, la classification agronomique etait le meilleur indicateur, suivi du systeme ARDA et enfin de lindice de productivityé de l'enquête des sols. Étant donné les concepts de base de ces systèmes de classification, cette tendance n‘était pas complètement inattendue. Les résultats suggèrent que le facteur de “management” devrait jouer un rôle plus large en développant des systèmes de classification des sols viables et que la coopération devrait être recherchée parmi les différentes disciplines concernées par Vutilisation agricole des sols.  相似文献

What really works   总被引:1,自引:0,他引:1  
When it comes to improving business performance, managers have no shortage of tools and techniques to choose from. But what really works? What's critical, and what's optional? Two business professors and a former McKinsey consultant set out to answer those questions. In a ground-breaking, five-year study that involved more than 50 academics and consultants, the authors analyzed 200 management techniques as they were employed by 160 companies over ten years. Their findings at a high level? Business basics really matter. In this article, the authors outline the management practices that are imperative for sustained superior financial performance--their "4+2 formula" for business success. They provide examples of companies that achieved varying degrees of success depending on whether they applied the formula, and they suggest ways that other companies can achieve excellence. The 160 companies in their study--called the Evergreen Project--were divided into 40 quads, each comprising four companies in a narrowly defined industry. Based on its performance between 1986 and 1996, each company in each quad was classified as either a winner (for instance, Dollar General), a loser (Kmart), a climber (Target), or a tumbler (the Limited). Without exception, the companies that outperformed their industry peers excelled in what the authors call the four primary management practices: strategy, execution, culture, and structure. And they supplemented their great skill in those areas with a mastery of any two of four secondary management practices: talent, leadership, innovation, and mergers and partnerships. A company that consistently follows this 4+2 formula has a better than 90% chance of sustaining superior performance, according to the authors.  相似文献

Stress is rampant, stress is growing, and stress hurts the bottom line. A 1999 study of 46,000 workers revealed that health care costs are 147% higher for those who are stressed or depressed, independent of other health issues. But what exactly is stress? It usually refers to our internal reaction to negative, threatening, or worrisome situations--a looming performance report, say, or interactions with a dismissive colleague. Accumulated over time, negative stress can depress you, burn you out, make you sick, or even kill you--because it's both an emotional and a physiological habit. Of course, many companies understand the negative impact of cumulative stress and offer programs to help employees counteract it. The problem is that employees in the greatest need of help often don't seek it. Since 1991, the authors have studied the physiological impact of stress on performance, at both the individual and organizational levels. Their goal largely has been to decode the underlying mechanics of stress. They've sought not only to understand how stress works on a person's mind, heart, and other bodily systems but also to discover the precise emotional, mental, and physiological levers that can counteract it. After working with more than 50,000 workers and managers in more than 100 organizations, the authors have found that learning to manage stress is easier than most people think. They have devised a scientifically based system of tools, techniques, and technologies that organizations can use to reduce employee stress and boost overall health and performance. In this article, they use the story of someone they call Nigel, a senior executive with whom they've worked, to describe how these techniques reduce stress in the real world.  相似文献

Precautionary Demand for Education, Inequality, and Technological Progress   总被引:2,自引:1,他引:1  
This paper offers an explanation for the evolution of wage inequality within and between industries and education groups over the past several decades. The model is based on the disproportionate depreciation of technology-specific skills versus general skills due to technological progress, which occurs randomly across sectors. Consistent with empirical evidence, the model predicts that increasing randomness is the primary source of inequality growth within uneducated workers, whereas inequality growth within educated workers is determined more by changes in the composition and return to ability. Increasing randomness generates a precautionary demand for education, which we show empirically to be significant.  相似文献
