大力发展港口经济推动经济增长方式转变

很多国际化大都市都是依托港口和临港经济发展起来的.港口不仅为港口城市带来大量的物流、人流和资金流,更为重要的是,港口具有强大的资源集聚和整合能力,能够带动港口城市及其周边地区制造业的快速发展,进而为银行、保险、贸易、中介服务等生产性服务业,以及旅游、餐饮、商业、会展等消费性服务业的快速发展提供巨大的发展空间,使港口与港口城市以及周边城市群之间形成"港兴城兴"的良性互动,实现共同繁荣和发展.港口成为港口城市所在区域乃至整个国家经济发展的重要因素.     

The taming of the Shrew(ish snake)?

An article in the last issue of INTERECONOMICS discussed problems of the monetary integration in Europe as they may arise under the new European Monetary System¹. It dealt more particularly with the exchange rate problems whereas the following contribution is concerned with the intervention and credit mechanism.     

Comments on qualitative results for investment proportions

Some mean/variance efficient portfolios will have positive investments in all individual assets when covariances satisfy the conditions given here. These conditions are more useful empirically than qualitative results that depend on the inverse covariance matrix. The prospect appears dim for general and useful qualitative results.     

Bayesian estimation of a random coefficient model

This paper carries out a Bayesian analysis of the Hildreth-Houck (1968) random coefficient model and applies it to some cross-section production function data. Posterior distributions for mean coefficients, actual coefficients, variances and variance ratios are derived. The variance ratio posteriors are largely uninformative but they do lead to relatively informative densities on the variances, and the problem of negative variance estimates, obtained with previous techniques, is overcome. Posterior densities for the mean coefficients are not extremely sensitive to the variance ratios.     

World Food Council's Tenth Session

The World Food Council held its 10th ministerial session from 11–15 June in the Africa Hall of the UN Economic Commission for Africa, which is located in Addis Ababa, Ethiopia. The meeting was historic: ten years had swiftly passed by since the World Food Conference met in Rome. What had been accomplished? The solemnly proclaimed resolution on the eradication of hunger had obviously not been fulfilled. In fact, the world's hungry and malnourished continue to prevail at around the half-billion number. Moreover, Africa was in the throes of a food crisis which had almost swept across that drougt-plagued continent, at least south of the Sahara.
