In recent years, growing interdependence in East Asia through trade and financial cooperation heightened the need for East Asian Economies to engage in closer regional economic relations. This paper attempts to discuss emerging economic integration efforts in East Asia with special reference to bilateral and regional free trade agreements. It discusses backgrounds for recent developments of East Asian regionalism in terms of deepening intraregional economic dependence and financial cooperation, and South Korea's position towards FTAs with major trading partners as well as East Asian economic integration. Important issues and challenges for an East Asian FTA are presented. 相似文献

When consumption betas of stocks are computed using year‐over‐year consumption growth based upon the fourth quarter, the consumption‐based asset pricing model (CCAPM) explains the cross‐section of stock returns as well as the Fama and French (1993) three‐factor model. The CCAPM's performance deteriorates substantially when consumption growth is measured based upon other quarters. For the CCAPM to hold at any given point in time, investors must make their consumption and investment decisions simultaneously at that point in time. We suspect that this is more likely to happen during the fourth quarter, given investors' tax year ends in December. 相似文献

叶绿素是反映水体富营养化程度的一个重要参数,遥感提取内陆水体叶绿素浓度是实现内陆水体富营养化动态监测的一个重要途径.内陆水体大部分属于二类水体,受人类活动干扰较大,富营养化严重,其复杂的水体光学特性增加了叶绿素遥感信息提取的难度.目前内陆水体叶绿素遥感信息提取取得了一定的进展,但提取的精度有待进一步提高,模型的普适性与稳定性需进一步研究.文章总结了近年来内陆水体叶绿素遥感提取所用的遥感数据源及其提取方法,分析了各遥感数据及提取方法的优缺点;讨论了目前内陆水体叶绿素遥感信息提取存在的问题并对研究进行了展望. 相似文献

Inflation expectations play a key role in determining future economic outcomes. The associated uncertainty provides a direct gauge of how well‐anchored the inflation expectations are. We construct a model‐based measure of inflation expectations uncertainty by augmenting a standard unobserved components model of inflation with information from noisy and possibly biased measures of inflation expectations obtained from financial markets. This new model‐based measure of inflation expectations uncertainty is more accurately estimated and can provide valuable information for policymakers. Using U.S. data, we find significant changes in inflation expectations uncertainty during the Great Recession. 相似文献
