The first objective of this article is to clarify which model best captures the structure and trend of the influence of social origin on children's education. The second objective is to analyse how general conclusions on historical trends in educational reproduction change if we add mother's status background to the model. Six contrasting hypotheses are derived fromthe body of literature dealing with models on families' socioeconomic status. All hypotheses are translated into empirical models and their explained variance is compared. A pooled data set is used that contains data from the Netherlands, West Germany, and the USA. The Modified Dominance Model, that distinguishes the influence of the highest from thelowest status parent, has the best model fit. Regarding the second objective we see that adding the mother's influence to that of the father's does not change general conclusions on trends in educational reproduction. Over time the influence of both parents decreases continuously. However, the influence of the mother's education and occupational status on children's educational attainment is substantive.  相似文献

Financial Accounting Standard (FAS) 133 requires business entities to document their anticipation of hedge effectiveness in order to qualify for hedge accounting treatment of gains and losses from financial derivatives. In the absence of specific guidelines, the accounting industry has espoused the "80–125" rule for determining hedge effectiveness. But the authors observe that meaningful assessment of anticipated hedge effectiveness must consider two distinct aspects of a firm's hedging strategy: (1) the strength of the hedging relationship, which is determined by the choice of the hedging instrument; and (2) the position taken in the hedging instrument relative to the holdings of the hedged item. They take both aspects of hedging into consideration in developing alternative measures of hedge effectiveness and distinguishing between the potential and attained effectiveness of a particular hedge. This approach enables the user to evaluate the relative merits of alternative hedging strategies to support risk management decisions, and also to document a selected hedging strategy's anticipated effectiveness for purposes of compliance with FAS 133. While the authors endorse a fairly broad interpretation of hedge effectiveness, their approach can also be used in the narrower context of an "80–125" rule.  相似文献

Abstract .  Grossman and Helpman (1994) explain tariffs as the outcome of a lobbying process. In most empirical implementations of this framework protection is instead measured using non-tariff barriers. Since tariffs allow the government to fully capture the rents from protection, while non-tariff barriers do not, the existing parameter estimates of the protection for sale model are likely to be biased. To address this problem, we augment the framework by considering instruments that allow partial capturing. Our specification is supported by the data, where we find that only 72–75% of the rent from protection is appropriated by the government.  相似文献

Abstract:   This paper examines the characteristics of firms that account for deferred tax liabilities related to government investment grants under an extended adoption timing period. Not only the recognition but also the timing decision is associated with changes in future performance and changes in the debt structure. Recognisers outperform non‐recognisers in the future, while early recognition is related to post recognition performance but only for those firms that currently perform well. Changes in the balance sheet structure are also related to both decisions. Firms with recent increases in the debt level tend to postpone recognition, while currently well‐performing firms that increase their future debt level are less likely to recognise deferred taxes.  相似文献

Rumors   总被引:3,自引:0,他引:3  
A Kyle (1985) model with private information diffusion is used to examine the motivation to spread stock tips. An informed investor with limited investment capacity spreads imprecise rumors to an audience of followers. Followers trade on the advice and move the price. Due to the imprecision of the rumor, the price overshoots with positive probability. This gives the rumormonger the opportunity to trade twice: First when she receives information, then when she knows the price to be overshooting. In equilibrium, rumors are informative and both rumormongers and followers increase their profits at the expense of uninformed liquidity traders.  相似文献

Increasing concern in scientific and policy-making circles about the possibility of global warming induced by the accumulation of CO2 and other greenhouse gases in the atmosphere has promoted the consideration of policies to limit emissions of these gases. This paper gives an overview of policy instruments targeted at the control of CO2 emissions, including the command-and-control approach, energy taxes, carbon taxes and tradeable carbon permits, with special attention being paid to the economic instruments.  相似文献

This article addresses the societal and cultural aspects of bioreserves and environmental restoration programmes. It begins with a discussion of bioreserves, then uses the example of a Man and Biosphere (MAB) inspired study of the US Everglades to illustrate how land has been shaped historically by culture and technology. It then demonstrates how current conflicts of values and culture, from both inside and outside the region, from interest groups with both pragmatic and emotional stances, are determining the future of an environment—the Everglades. The article thereby shows how human values and perceptions impact on the development of a sustainable Everglades, using the findings of surveys and public meetings to highlight the interests of the competing communities, ethnic and interest groups involved. If bioreserves are to survive they cannot become alienated from the people in the regions in which they are located.  相似文献

Operational Research and the environment   总被引:1,自引:1,他引:0  
The discipline of Operational Research (OR) is primarily concerned with improving the effectiveness and efficiency of decision processes. These processes take place everywhere in society: industry, banking, agriculture, government, politics. Frequent use of mathematical optimization models is typical of OR. Since the early '80s these models are increasingly packaged in a user-friendly way, as Decision Support Systems. In the following we will illustrate how OR can be used to describe and solve a number of environmental problems.  相似文献

Summary In a small open economy it is optimal to first maximize national income and second choose the best consumption point.The same two-step procedure under (quantitative) uncertainty is suboptimal if one of the goods is used as numéraire. Optimality is restored however, if nominal prices are deflated by the exact price index. Hence there is equivalence between the appropriate two-step procedure and the introduction of a stock market under uncertainty (Diamond 1967) under ideal circumstances.I would like to thank, without implicating, Peter van Bergeijk, Steven Brakman, Willem Buiter, Richard Gigengack, Jean-Marie, Viaene, Casper de Vries and an anonymous referee for useful comments and Angelique van Haasteren and Martijn Herrmann for graphical assistance.  相似文献
