论我国黄金投资 总被引:1,自引:0,他引:1
吴顺达 《长春金融高等专科学校学报》2004,(2):1-6
中国黄金体制市场化改革,最终导致了黄金珠宝业市场配置资源体系的形成,并使黄金、金融投资分离开来,形成了货币黄金、金融投资黄金、商品黄金构成的新黄金体系.如何在改革中把握投资商机,对于中国黄金投资者和经营者无疑是极为重要的.伴随国际金价的波动,如果投资者操作得当,可以从黄金投资中获得稳定的收益. 相似文献

正确理解素质教育的内涵是整个素质教育工作的关键,应从素质与素质教育两个方面着手研究素质教育。素质是知识、能力与服务的有机结合,素质教育是教育的目标,是一切教育活动的组织原则。素质教育要与学生培养目标相结合,不讲培养目标就失去了教育方向。 相似文献

We analyse a disregarded environmental policy instrument: a switch in government expenditure away from energy (or other natural
resources) and toward a composite good which includes energy-saving expenditure. We first develop two variants of an analytical
general equilibrium model. A composite good is produced with constant returns to scale, and energy is imported or produced
domestically with diminishing returns, yielding a differential rent to its owners. The government purchases energy and composite
goods from private firms. Such a policy unambiguously increases employment. It also raises private consumption and welfare
under two conditions: (i) it is not too costly and (ii) the initial share of the resource is smaller in public spending than
in private consumption, or the difference is small enough. We then run numerically a model featuring both importation and
domestic production of energy (oil, gas and electricity), for the OECD as a whole. Simulations show that employment, welfare
and private consumption rise. We provide magnitudes for different parameter values.

Synopsis We describe the first effort at creating a global ex-vessel fish price database, which is required for understanding the economic
behavior of participants in the world’s fisheries. We demonstrate potential applications of the database by linking it to
a spatially defined catch database, which makes it possible to attach landed values to species in both time and space. This
is the first database available publicly where interested members of the public, researchers and managers can easily find
and access ex-vessel prices of the world’s major commercial fish species. Preliminary results indicate that the average real
price of a number of species have declined between 1950 and 2002. The estimated landed value of fish globally, in year 2000
dollars, was about US$24 billion in 1950. It increased steadily to about US$90 billion in the early 1970s, reached a peak
of US$100 billion at the end of the 1980s, and declined to about US$80 billion in 2000. The top 15 fishing countries cumulatively
account for 79% of total real landed value, with Japan leading, even though the value of its landings has been declining.

Abstract. Only rarely have empirical studies analysed the responses of Taiwanese manufacturing firms to ISO 14001, despite firm responses to environmental issues being an important aspect of environmental management. This study empirically examines the determinants of firms' environmental self-governance. Export oriented Taiwanese firms, which face environmental concerns from foreign consumers, are found to be more likely than domestic focused firms to adopt ISO 14001. This study also finds that several firm attributes are decisive for firm adoption of ISO 14001. However, this study does not find any significant impact of local governors' political party affiliation on firms' ISO 14001 certifications. 相似文献

Recent application of the switching regression model to allocate workers into the primary and secondary labor markets is
considered to be the best solution to the classification problem of the empirical testing of the dual labor market theory.
In such models, normality of the error terms is assumed. This paper adopts the switching regression model to test the dual
labor market theory by assuming different distributions of the error terms. The test results strongly support the dual labor
market theory regardless of the assumption one makes about the error terms. However, the results indicate that different distribution
can lead to different percentage distributions of workers in the two segments. In particular, the normal distribution generates
more workers in the primary segment than the non-normal distributions. Therefore, care must be taken not to generalize the
type of industries or occupations that fall under the primary and secondary segments.

Summary. I prove that the equilibrium set in a two-player game with complementarities, and totally ordered strategy spaces, is a sublattice
of the joint strategy space.

Many accounting educators believe that the student learning of accounting is better facilitated over a longer period of time, rather than a shorter period of time. This study examined the results of student performance in two introductory accounting courses, comparing student performance results of four-week summer classes with the results of traditional 16-week courses. In this research, the same professor taught the spring and summer ACC 201 courses, and two other professors taught both the spring and summer ACC 211 courses. Also held constant were the lecture material, course assignment, and test content. The results of the study indicate that in general, students taking introductory accounting over four weeks fare about as well as students who take introductory accounting over a traditional 16-week period. These results have potential importance beyond accounting education and provide support to universities offering more block courses to better serve individual student needs. 相似文献

Double Moral Hazard,Monitoring, and the Nature of Contracts 总被引:8,自引:0,他引:8
Pradeep Agrawal 《Journal of Economics》2002,75(1):33-61
generalized double-sided moral-hazard model, with risk-averse parties who mutually monitor each other (to get a reasonable idea of outcome/effort).
The model considers trade-off between monitoring costs and moral hazard costs, which are endogenously determined by the extent
of monitoring.
Using this model, we formally prove a generalized version of Coase's conjecture – that the optimal contract minimizes the
agency and risk costs. We then show how varying assumptions about the feasibility or cost of monitoring of the outcome or
the worker's effort lead to different contracts being optimal. The analysis is then used to explain the nature of contracts
observed in practice under many different situations. We will give an explanation as to why industrial workers typically work
under wage contracts, while share contracts are common in agriculture and will explain why profit sharing is more common for
senior managers than for the production workers.
