THE CONSTITUTIONAL PROPOSAL OF THE EUROPEAN CONVENTION: AN APPRAISAL AND EXPLANATION

The recent European Convention was constructed so that the median voter on the convention had a bias in favour of centralisation. The conclusions of the Convention were therefore not surprising. The European Constitutional Group has made a number of suggestions for change to the Convention that could reverse its centralising approach.     

小型FMCW近炸引信高度表

<正> 倾销与反倾销历来是国际贸易中的一对矛盾,尤其是西方国家为了争夺市场,打败竞争对手,总是利用种种手段,包括倾销手段来进行竞争。但是,为了对付别国的倾销,从20世纪初开始,西方一些国家又先后通过国内立法对倾销加以限制。然而,倾销与反倾销的斗争并未就此停止。第二次世界大战以后,一些国家通过关贸总协定这一国际性协定对倾销加以规范并予以限制。进入80年代以后,一方面由于西方国家的经济普遍不景气,复苏乏力,因此纷纷加强对进口的限制,反倾销就成为达到这一目的的最有力的工具之一;另一方面,一些发展中国家在扩大其对外贸易的同时,出于保护国内产业发展的需要,也制订了自己的反倾销法。这样,倾销与反倾销的斗争在更大的范围内展开了。本文试就我国反倾销立法的几个问题加以论述。     

论我国开展国际营销的重要意义

国际营销是在市场营销的基础上发展起来的,诞生至今仅有三十年左右的历史。但是随着国际经济联系的日益紧密化,国际分工、国际竞争的日趋深刻化,国际营销越来越受到企业界和学术界的重视,有关国际营销理论的研究正呈方兴未艾之势。     

Equal opportunity and poverty reduction: How should aid be allocated?

This paper analyzes a model of aid allocation equalizing the opportunity between recipient countries to reach a common poverty reduction goal. We propose a fair and efficient aid allocation based on a multicriteria principle. The model considers structural handicaps in recipient countries in terms of lack of human capital and economic vulnerability, their initial poverty, and the natural gap between the growth rate required to reach a development goal and the observed one. We show that our proposed aid allocation favors poor and vulnerable countries with our multicriteria principle. It substantially differs from the observed allocation. Analyses also shed light on the impact of the donors' aversion to the low natural growth gap in recipient countries on the optimal aid allocation and the marginal efficiency of aid.     

USE OF ERRORS OF PREDICTION IN IMPROVING FORECAST ACCURACY: AN APPLICATION TO WOOL IN AUSTRALIA

Over the past 20 years, the RAE has produced commodity forecasts in BAE Trends in Australian Agricultural Commodities, Farm Costs and Farm Incomes and other commodity outlook publications. There have been several studies on the accuracy of the forecasts, either comparing RAE forecasts with naive forecasts or making simple calculations of biases and standard deviations. Such approaches are not sufficiently informative in that they do not give any indication of what has caused the inaccuracies, nor of the timing of significant changes in prediction accuracy. In this analysis, an attempt is made to improve upon this situation using some tools of time series analysis.     

Optimal consumption policies in illiquid markets

We investigate optimal consumption policies in the liquidity risk model introduced by Pham and Tankov (Math. Finance 18:613–627, 2008). Our main result is to derive smoothness C ¹ results for the value functions of the portfolio/consumption choice problem. As an important consequence, we can prove the existence of the optimal control (portfolio/consumption strategy) which we characterize both in feedback form in terms of the derivatives of the value functions and as the solution of a second-order ODE. Finally, numerical illustrations of the behavior of optimal consumption strategies between two trading dates are given.
