Roman F. Warmke 《The Journal of economic education》2013,44(1):89-99
Asserting that the basic problem in high school economics is that we have not identified “what high school economics ought to be,” Warmke proceeds to spell out some of the specific obstacles hindering the development of more and better secondary level courses. He then discusses some of the more encouraging trends in research, teaching, teacher-training, materials development, and the like, and makes some cautious projections for the future. 相似文献

Financial time series are often non‐negative‐valued (volumes, trades, durations, realized volatility, daily range) and exhibit clustering. When joint dynamics is of interest, the vector multiplicative error model (vMEM; the element‐by‐element product of a vector of conditionally autoregressive scale factors and a multivariate i.i.d. innovation process) is a suitable strategy. Its parameters can be estimated by generalized method of moments, bypassing the problem of specifying a multivariate distribution for the errors. Simulated results show the gains in efficiency relative to an equation‐by‐equation approach. A vMEM on several measures of volatility justifies a joint approach revealing full interdependence.

Something about the immense importance of UNCTAD II can be inferred from the hypothetical assumption that the joint attempt of 132 nations to build a “world without poverty, misery, and despair” might founder, and from sober consideration of the effects of such an event. Numerous representatives of developing countries, in their introductory addresses to the Conference, have stressed the indispensable need for bridging the gap which separates the world into the two camps of the affluent and the poor, lest economic backwardness cause again and again major conflicts. We have discussed some aspects of UNCTAD II with Dr Schulz, the deputy acting head of the German deannation, shortly before he left Germany for New Delhi. 相似文献

This article reviews the international debate on statistical indicators. It describes historical backgrounds, as well as the present chaotic situation. It discusses what statistical indicators are and what they are for, as well as criteria for the choice of indicators, designed to monitor the achievement of economic, social, demographic, environmental and other goals set by United Nations conferences. Some suggestions for future work are made. 相似文献

The authors conducted a painstaking review of widely used economics textbooks to determine if or how issues relating to race and gender are treated. In doing so, the authors also shed light on the nature of the treatment of these issues. 相似文献

The cash-flow valuation method (CFVM) has been developed in Canada for the valuation of insurance company annuity products. Its range of application is expected to be extended shortly to the valuation of most other life insurance company products. The CFVM is based on the use of “best-guess” assumptions, supplemented by specific provisions for adverse deviations. In this paper, special attention is paid to the calculation of the provision for adverse deviations with respect to the interest rate risk. We show that the determination of this provision is the analog for life insurance and annuity policy liabilities of the calculation by banks of Value at Risk (VaR) with respect to portfolios of securities held for trading. 相似文献
