Georgescu-Roegen's work is usually divided into two categories, his earlier work on consumer and production theory and his later concern with entropy and bioeconomics beginning with his 1966 introductory essay to his collected theoretical papers published in the volume Analytical Economics. Most economists usually praise his earlier work on pure theory and ignore his later work which is highly critical of neoclassical economics. Those economists sympathetic to his later work usually take the position that he “saw the light” and gave up neoclassical theory some time in the 1960s to turn his attention to the issues of resource scarcity and social institutions. It is argued here that there is an unbroken path running from Georgescu's work in pure theory in the 1930s, 1940s, and 1950s, through his writings on peasant economies in the 1960s, leading to his preoccupation with entropy and bioeconomics in the last 25 years of his life. That common thread is his preoccupation with “valuation.” The choices our species makes about resource use and the distribution of economic output depends upon our valuation framework. Georgescu-Roegen's work begins in the 1930s with a critical examination of the difficulties with the hedonistic valuation framework of neoclassical economics, moves in the 1960s to the conflict between social and hedonistic valuation, and culminates in the 1970s and 1980s with his examination of the conflict between individual, social, and environmental values. This paper traces the evolution of Georgescu-Roegen's thought about valuation and the environmental and social policy recommendations which arise out of his bioeconomic framework.  相似文献

This paper subjects Lucas's output–inflation trade-off study to further empirical investigation. The cross-country study divides the 111 countries covered into 90 developing countries and 21 advanced countries. Lucas's proposition is that volatility of aggregate demand growth should reduce the impact of aggregate demand growth on the cyclical output and the implication of this is that there is no output–inflation trade-off in line with the natural rate theory. We employ annual data over periods that fall between 1958 and 1985 in order to conduct the test. Our findings suggest that Lucas's proposition is valid for developed economies but not for developing economies.  相似文献

This paper studies the determinants of technological catch‐up considering spatial and sectoral aggregation of industries. We investigate how geographical and technological proximity to the technology leader impact regional employment growth. We model technological progress by means of a hierarchical process of catch‐up to the technology leader. We also incorporate measures for knowledge spillover effects to test the roles of competition, specialisation, and diversity at the industry level. Empirical results using data at the county level for different economic sectors (2‐dig NAICS) for the United States indicate that human capital plays a crucial role in promoting sectoral employment growth. The association between technological/geographical distance to the technology leader and employment growth varies across sectors.  相似文献

American agriculture is suffering from severe structural adjustments and from its worst financial depression since landmark price and income policies were legislated more than half a century ago. As much as one-third of the $220 billion in agricultural debt is now delinquent, nonaccrual, or subject to renegotiation. Land values have fallen precipitously in the past few years. Farm foreclosures are near 1930 Depression levels. The congressional debate over programs that could determine the course of U.S. agriculture for the remainder of the century began in the summer of 1985.  相似文献

Drawing on recent advances in exchange rate regime classifications, the paper examines empirically the effect of exchange rate regimes on foreign direct investment (FDI) flows to developing countries. Using system generalized methods of moments estimation on a panel of 70 developing countries for the period 1985–2004, we find that developing countries adopting de facto fixed or intermediate regimes significantly outperform those opting for a flexible exchange rate system in attracting FDI flows. No statistically significant differences in the FDI‐inducing properties of fixes, intermediates and floats are found using the International Monetary Fund official classification.  相似文献

When the American Association of Colleges of Nursing introduced the Clinical Nurse Leader"s (CNL) pilot project in 2004, it was the first time in more than 40 years that an attempt was made to introduce a new role to the profession. This new role was designed to address many challenges related to patient care in the current health care delivery system including a need for more effective clinical problem solving, better coordination at the point of care, stronger interdisciplinary relationships, and more rapid implementation of evidenced-based practice findings at the patient-provider interface. Critics from both academic and practice settings have questioned the need and wisdom of introducing a new role to the profession at this time. The factors that led some nursing leaders in early stages of this project to be proactive and involve their organizations as early adopters of the CNL role were examined in this study. Five major factors were identified from the research to form a framework designed to explain organizational participation: organizational needs, a desire to improve patient care, an opportunity to redesign care delivery, the promotion of the professional development of nursing staff, and the potential to enhance physician-nurse relationships. The ability of academic and service partners to forge the types of relationships and promote best practices as is occurring in the CNL project may be a critical success factor in confronting the current and impending nursing shortage.  相似文献

Workload control under continuous order release   总被引:1,自引:0,他引:1  
Workload control is a production planning and control concept specifically designed for complex manufacturing environments. Past research on Workload control has been essentially focused on discrete order release. This means that release of orders to the shop floor takes places on a periodic basis. Continuous order release has been somehow neglected, in spite of its apparent potential for improving system performance, including the reduction of order flow times. This paper presents a simulation study of this order release approach. The study contributes for improving the basis for setting workload norms, selecting the workload control strategy and deciding upon routing alternatives under continuous order release.  相似文献

While the poverty implications of off-farm income have been analyzed in different developing countries, much less is known about the impact of off-farm income on household food security and nutrition. Here, this research gap is addressed by using farm survey data from Nigeria. Econometric analyses are employed to examine the mechanisms through which off-farm income affects household calorie and micronutrient supply, dietary quality, and child anthropometry. We find that off-farm income has a positive net effect on food security and nutrition. The prevalence of child stunting, underweight, and wasting is lower in households with off-farm income than in households without. Using a structural model, we also show that off-farm income contributes to higher food production and farm income by easing capital constraints, thus improving household welfare in multiple ways.  相似文献

We consider a market comprising a number of perfectly complementary and homogeneous commodities. We concentrate on the incentives for firms producing these commodities to merge and form a vertical syndicate. The main result establishes that the nucleolus of the associated market game corresponds to the unique vector of prices with the following properties: (i) they are vertical syndication-proof, (ii) they are competitive, (iii) they yield the average of the buyers- and the sellers-optimal allocations in bilateral markets, and (iv) they depend on the traders’ bargaining power but not on their identity. The proof uses an isomorphism between our class of market games and the entire class of bankruptcy games.  相似文献
