Consider m observers each classifying n objects into one of two disjoint categories. The problem of measuring agreement among m observers is discussed. A new approach, based on a specific parametric model, is recommended. The approach is applied to data on agreement in judging biopsy slides.  相似文献

Abstract. Contingent valuation is a technique being developed by economists for the valuation of environmental commodities not traded in markets. This paper discusses the major problem areas associated with this method of value estimation. These comprise bias (strategic, hypothetical and design biases); the discrepancy between willingness-to-pay and compensation demanded; the aggregation procedure; the choice of question format; and non-use values. Some evidence from comparative studies is reported, and comments made on the accuracy of contingent valuation answers, Finally, the conditions under which contingent valuation seems to operate best are set out.  相似文献

Existing numerical characterizations of the optimal income tax have been based on a limited number of model specifications. As a result, they do not reveal which properties are general. We determine the optimal tax in the quasi-linear model under weaker assumptions than have previously been used; in particular, we remove the assumption of a lower bound on the utility of zero consumption and the need to permit negative labor incomes. A Monte Carlo analysis is then conducted in which economies are selected at random and the optimal tax function constructed. The results show that in a significant proportion of economies the marginal tax rate rises at low skills and falls at high. The average tax rate is equally likely to rise or fall with skill at low skill levels, rises in the majority of cases in the centre of the skill range, and falls at high skills. These results are consistent across all the specifications we test. We then extend the analysis to show that these results also hold for Cobb-Douglas utility.  相似文献

The properties of the labour market are such that moderate employment shifts can be accommodated by, and might even encourage, the natural movement of labour between jobs. But the scale and extent of employment adjustments in recent years has produced an altogether different response. Voluntary movement has fallen dramatically as unemployment has risen. Redundancies have increased in importance in absolute and relative terms. The pace of adjustment in recent years has reduced the natural flexibility of the labour market and has created a serious impediment to the optimal distribution of labour. Moreover, an economic doctrine which emphasizes the importance of flexibility and personal choice in the labour market, has effectively reduced both.  相似文献

The issues of exterritoriality of big business capital and the clash of interests between big capital owners and regional economic policy are discussed with special reference to the Krasnoyarsk krai economy. The stages in the establishment of major integrated business groups (IBGs), the formation of their financial flows, and their influence on the region’s economy are analyzed.  相似文献

We consider the origins of global current account imbalances. We first discuss how the expansion of the US current account deficit and the decrease in global real interest rates can be reconciled with the widespread view that American expansionary fiscal policy is partly the source of current trends. We then investigate empirically the medium‐term determinants of the current account using a model that controls for factors related to institutional development. In addition to the conventional macroeconomic factors, we examine a series of environmental factors, including the degree of financial openness and the extent of legal development. We find that for industrial countries, the government budget balance is an important determinant of the current account balance; the budget balance coefficient is 0.10 to 0.49 depending on model specifications. These varying estimates lead us to conclude that fiscal factors might be as important as excess savings arising from East Asia.  相似文献

A laboratory experiment explored the impact of various power-based copy approaches upon readers' responses to print advertising messages. The treatments employed were derived from French and Raven's bases of social power at two levels of information content. Response measures included copy-and brand-related variables and recall. Results indicate that there are significant differences in responses owing to both the base of social power and the information level used.  相似文献

We report the results of a nine-year field study that examines how responsibility accounting (RA) is used to manage horizontal relationships among several responsibility center (RC) managers including those who work on committees or cross-functional teams. We find theory-consistent evidence that the goal-congruent design or redesign of accounting and participation practices in general, and of RA in particular, depends on the magnitude, scope, and speed of organizational process change. When there is a change in the magnitude, scope, and speed of organizational process change, we find that the measurability of RC managers’ financial performance can change, and we also find that using RA to manage RC boundaries is an important mechanism for achieving goal-congruent behavior and avoiding dysfunctional behavior. Moreover, we show that several accounting and participation practices (e.g., activity-based costing, open book accounting, project budgeting, cross-functional teams) support RC boundary management that involves framing or reframing RC boundaries so as to influence competitive or cooperative behavior among RC managers. Finally, this study contributes by introducing a new research method to the accounting literature that is effective in structuring and interpreting longitudinal field data in relation to theoretical expectations.  相似文献
