The damage to a reputation has long been viewed as the main and most effective deterrent against plagiarism among professional economists. We show that it is rational for individuals in the economics profession who want to plagiarize to engage in this activity given current incentives. Recent research concerning plagiarism in the economics profession has highlighted the frequency that instances of plagiarism have occurred. Our paper shows how it is possible given current incentives in the profession for these instances to go unreported therefore removing the threat of damage to a plagiarist’s reputation. We also discuss the harm that such actions cause to the original author and to the profession as a whole.  相似文献

We examine the real convergence hypothesis for 14 OECD countries looking at the fractional order of integration of the differences of real GDP per capita in these countries with respect to the United States. Using parametric procedures, the results vary depending on how we specify the I(0) disturbances. If they are white noise, convergence is achieved for Canada and Australia, and with autocorrelated disturbances, this hypothesis is satisfied for France and the Netherlands. However, allowing for a break at World War II, evidence of convergence is obtained for all countries. JEL no. C32, O41  相似文献

A comparative study of external mortality risk factors according to World Bank experts (Dying Too Young Report, 2005) and findings of other projects, as well as mortality reduction programs, is presented. The World Bank experts overrate the significance of smoking and lead pollution as mortality factors and underrate that of alcohol, air pollution, and unfavorable occupational environments. In addition, the impacts of radon, climate warming, and low temperatures, which are very important negative factors for Russia, are overlooked in the Report. Although mortality reduction measures are very topical under the current demographic crisis, certain federal target programs envisage very general measures, and the death rate remains high. Road Safety Improvement, which is the most concrete among these programs, may indeed help reduce road accident-related mortality. The importance of air pollution as a risk factor may grow as a result of changes in the structure of the fuel balance and an increased share of coal combustion.  相似文献

Economic historians hypothesize that households in the nineteenth century substituted away from carbohydrates and fiber and towards protein and fat as their incomes rose. Anthropometric historians assert that there was increased nutrient intake without any nutritional substitution. I test these hypotheses using the 1888 Cost of Living Survey. I fail to reject the hypothesis that the income elasticity of fiber is greater than or equal to the income elasticities of protein, fat, or sugar—contrary to the nutritional substitution posited by economic historians. A food modified Engel curve reveals that the shares of carbohydrates, fat, and sugar in the diet vary with household income, but the shares of protein and fiber do not. I do find, however, that the share of protein from animal sources increases with household income. I also find that the diets of late nineteenth century industrial workers were surprisingly balanced by modern standards.  相似文献

This article presents reliable data on the life expectancy of the monks of Durham Priory between 1395 and 1529. The number of years that monks survived in this northern monastery plunged precipitously in the second half of the fifteenth century before staging a partial recovery in the early sixteenth. The experience of Durham monks mirrors the scale, direction, and timing of the data already produced for the monks of Canterbury and Westminster. While the precise relationship between monastic mortality and that of the population at large remains difficult to determine, there can be no doubt that the symmetry that has been established between mortality in three monasteries located in different parts of the country has important implications for our understanding of the demographic history of late medieval England.  相似文献

Technological progress has helped Bangladesh to achieve self‐sufficiency in rice production in 2001 from a heavy import‐dependence, despite doubling of population and a reduction in arable land since its independence in 1971. As the adoption of modern varieties (MV) of rice is reaching a plateau, particularly for the irrigated ecosystem, an important issue is whether the research system will be able to sustain the growth of production. The present paper addresses the following questions: (i) to what extent farmers have been replacing the old MV with the new MV, and (ii) what has been the impact of the variety replacement on productivity and profitability. How crucial is the continuous research and release of improved rice varieties toward improving farm production and income for farmers comes out as a clear message to policymakers from the current paper.  相似文献

The competitiveness of Russian industries: Current state and outlook   总被引:1,自引:0,他引:1  
Based on its definition of industrial sector competitiveness the paper presents a “competitiveness chart” of branches of industry as per postcrisis status and points out key contributing factors in the success/failure of industry groups. Development opportunities and threats of branches of industry are analyzed, leading to a long-term industry “competitiveness chart.” A detailed SWOT analysis is made of the strengths, weaknesses, opportunities, and threats for a number of key industries.  相似文献
