Most decision theories, including expected utility theory, rank-dependent utility theory and cumulative prospect theory, assume that investors are only interested in the distribution of returns and not in the states of the economy in which income is received. Optimal payoffs have their lowest outcomes when the economy is in a downturn, and this feature is often at odds with the needs of many investors. We introduce a framework for portfolio selection within which state-dependent preferences can be accommodated. Specifically, we assume that investors care about the distribution of final wealth and its interaction with some benchmark. In this context, we are able to characterize optimal payoffs in explicit form. Furthermore, we extend the classical expected utility optimization problem of Merton to the state-dependent situation. Some applications in security design are discussed in detail and we also solve some stochastic extensions of the target probability optimization problem.  相似文献

Since the United Nations Conference on Environment and Development in 1992, mountains have acquired global recognition as a specific issue in the promotion of sustainable development policies. Starting from the traditional roles of mountains for local societies and in modern geopolitics, this paper analyses the status that mountains have been acquiring though globalisation, and the modes of global mobilisation and recognition that have taken shape since 1992. Particular attention is given to the role of scientists, international organisations, some mountainous states, and “mountain people”. The specific characteristics of this process are discussed and compared to those pertinent to other goods, especially ‘geographical’ or ‘ecological’ goods such as tropical forests and Antarctica. Though the globalisation of mountain issues is part of a wider process of the recognition of environmental and cultural goods at a global level, it may be seen as the first example of a new category of global common good: “global common regions” or “glocal common good”.  相似文献

Previous research has documented a negative relationship between child disability and maternal labor supply. Because of data limitations, most studies in this literature use broad measures of disability, which may obscure important differences among children with limiting health conditions. This paper presents new evidence on the labor supply of women with disabled children, exploiting disability information provided by 2000 US Census. This large nationally representative sample allows us to test for differences across different types of disabling conditions. We find that accounting for this heterogeneity in conditions is important. Using a broad definition of disability results in small differences between women with and without a disabled child. When we use a more detailed classification, we find larger labor supply reductions for mothers of children with physical disabilities or limitations in their ability to care for themselves. There is less evidence that having a child with either mental or emotional limitations or a sensory impairment is negatively related to employment or weekly hours. We also test for heterogeneous effects related to child age and maternal education. We find no clear pattern with respect to age and some evidence that the relationship between child disability and maternal labor supply is stronger for less educated mothers.  相似文献

Preference Erosion and Multilateral Trade Liberalization   总被引:2,自引:0,他引:2  
Because of concern that tariff reductions in Organisation forEconomic Co-operation and Development (OECD) countries willtranslate into worsening export performance for the least developedcountries, the erosion of trade preferences may become a stumblingblock for multilateral trade liberalization. An econometricanalysis of actual preference use shows that preferences areunderused because of administrative burdens—estimatedto be equivalent to an average of 4 percent of the value ofgoods traded. To quantify the maximum scope for preference erosion,the compliance cost estimates are used in a model-based assessmentof the impact of full elimination of OECD tariffs. Taking intoaccount administrative costs eliminates erosion costs in theaggregate and greatly reduces the losses for countries mostaffected by preference erosion.  相似文献

Using experiments in a procurement setting, this study examined the performance abilities of three auctions: the second-price, English, and a new ‘sealed offer’ English. Additionally, to see if dominant strategy learning would be transferred, after fifteen periods with one of the three auctions, all subjects completed a second 15 periods with the second-price auction. The English auction performed best overall. However, only limited learning was found to occur, with some subjects that had adopted the dominant strategy in the English switching in the second-price. Lessons from the new mechanism transferred better, but initial learning of the dominant strategy was slower.  相似文献

This study confirms that substantial barriers to market accesswill remain in both rich and poor countries following full implementationof the Uruguay Round agreement. The analysis finds that approximately40% of the costs of these barriers to developing countries arisefrom barriers to market access in industrial countries and 60%from barriers in developing countries themselves. The resultssuggest that there would be large gains to almost all regionsfrom a round of negotiations that increased market access inthe North and South. In Africa, the potential static gains frommultilateral reform appear to exceed those from preferentialliberalisation, without the well-known disadvantages of a preferentialapproach.  相似文献

Abstract

This paper presents historical death rates for Canada, Mexico, and the U.S. by sex and broad age group. The time period for this historical analysis begins with 1900 (1930 for Mexico). These data provide a quite consistent basis from which experts can develop and contrast their expectations for future mortality trends. Official mortality projections developed by government agencies of each of the three countries provide a starting point for this discussion.

During this century, death rates declined fairly rapidly in all three countries. However, the rate of mortality improvement has varied considerably across time periods: distinct periods of rapid and slow improvement are evident in the data, but are not consistent across the countries and have not yet been explained.

The historical rates of improvement in mortality have also varied greatly by age and sex: younger age groups have shown the most rapid proportional improvement in mortality in all three countries, and mortality improvement during this century has generally been greater for females than for males. However, the data provide evidence that this difference in the rates of mortality improvement between men and women has recently slowed, and even reversed, in the U.S. and Canada. Historical experience and projections are provided in graphs, in which death rates are plotted on a logarithmic scale. This approach allows easy detection of the extent to which rates of improvement have been changing (death rates with constant rates of improvement would be plotted as straight lines).

The official projections supplied for comparison provide strikingly similar outlooks for future potential mortality improvement. In each case, the relatively average rapid rate of mortality improvement experienced so far this century is assumed to slow in the future. In addition, rates of improvement are projected to be much more similar for all three countries across age groups and between the sexes.  相似文献
