新时期广东省山区人口控制探析

20世纪90年代以来，广东省的山区人口增长速度虽然得到了控制，但与珠江三角洲相比还存在一定差距，地区之间发展也不平衡，生育水平仍不稳定，有效的人口控制机制尚末真正形成。因此，必须建立保障体系 和切合实际人口控制工作新机制，把人口控制工作寓于服务之中；加强计划生育队伍建设，提高队伍整体素质和工作效率。     

走可持续发展的道路,必须树立科学的“资源优势”观

资源优势不等于经济优势,它不是固定不变的。其在现代经济中的作用已让位于科学技术,利用不当会转化为劣势。所以,走“可持续发展”道路,必须遵循开发资源坚持以科技为先导、以市场为导向、开采与保护并重的原则。

The impact of time duration between trades on the price of treasury note futures contracts

Recent research in finance has indicated that the institutional structure in which financial asset prices are determined can have a nontrivial impact on pricing. This report examines transaction level data for Treasury Note futures contracts traded at the Chicago Board of Trade (CBOT) to identify institutional, or market microstructure, impacts on the pricing of these contracts. Relatively few articles have conducted empirical research on the microstructure of U.S. futures trading due to the limited availability of comprehensive transaction level data from the futures exchanges. This report uses the CBOT's Computerized Trade Reconstruction database, a comprehensive transaction level dataset, to identify the price impact of the time duration between trades in a manner analogous to that of A. Dufour and R. F. Engle (2000). Unique differences from prior research include the application to futures contracts with their relative higher frequency of trading, as well as the investigation of the price impact of the number of active traders present on the trading floor and the trading volume. Subsequent price and sign of trade significantly relate to the time duration between trades, the number of floor brokers, and the trading volume. © 2004 Wiley Periodicals, Inc. Jrl.

Fixed Exchange Rates and Disinflation in Emerging Markets: How Large Is the Effect?

We examine developing countries which have institutional quality ratings for the effects of exchange rate rigidity on inflation. The level of institutional development exerts no effect on the impact of currency regimes. However, the interaction of institutional quality and exchange rates has, in the most plausible specifications, a negative impact on inflation. This suggests that fixed exchange rates exert at most a contingent effect on inflation, and indicates that countries in Eastern Europe and Latin America contemplating currency pegs would be better off improving institutional quality prior to adopting the euro or dollar and expecting a large subsequent disinflationary effect.
