Intergenerational earnings mobility in Singapore and the United States

This study compared intergenerational earnings mobility in Singapore and the United States by replicating the sample criteria in the Singapore National Youth Survey on the U.S. Panel Study of Income Dynamics. The mean estimated earnings elasticities are almost identical: 0.26 in Singapore and 0.28 in the United States. Transformed to 0.44 and 0.47 respectively to reflect permanent status, mobility in the two countries is moderately low compared internationally. The finding of similar mobility is not surprising given that the two countries have similar economic realities, welfare systems, education regimes, and labor structures. Policy makers face the daunting challenge of overcoming immobility and inequality while maintaining global competitiveness.

江苏省开展机动车维护制度研究的必要性

近年来,江苏省机动车保有量快速增长,污染物排放呈逐年上升趋势。但机动车污染防治工作仍停留在被动管理状态,未完全实现对在用车辆的多方动态监管,从而造成了现阶段＂重检测轻维护＂的局面。积极开展机动车维护制度的研究,找出切实可行的工作程序和管理办法,将有助于推进交通节能减排工作的开展。

Estimation of a Taiwan monetary reaction function with time varying parameters

This paper employs a nonlinear Kalman filter to examine the time-varying responses of Taiwan's monetary policy in the presence of a limited dependent variable. The Kalman filtered parameters reveal that the responses are not constant but change over time. Furthermore, a counter-cyclical reaction function is identified and a stronger than usual discretionary policy during the recessions is found.

Excess Liquidity,Housing Price Booms and Policy Challenges in China

Incorporating asymmetric cost and benefit of supplying excess liquidity into an otherwise standard time inconsistency model, this paper offers an explanation of the excess liquidity and housing price booms recently experienced in China. We find that the central bank's incentive to stimulate economic growth with excess liquidity fuels real estate prices and accelerates inflation bias. Therefore, the central bank should free itself from the pressure to achieve an economic growth rate higher than the potential level, and assign an appropriate weight to the real estate price fluctuations in the central bank's objective function, so that the central bank's policy of stimulating economic growth with excess liquidity can be constrained.

开放经济条件下的我国离岸金融监管

目前,国内对离岸银行监管的系统研究不多,对实务和政策操作具有指导意义的理论探讨就更少。我们结合实践经验,参考了国内外文献,综合分析了我国在开放经济条件下离岸银行及其监管问题,重点阐述我国离岸银行的概况,发展离岸金融市场的客观性、必要性,离岸金融的本质特征、运作模式和离岸金融监管重点等问题,并试图为监管部门提供政策建议。     

资本市场发展与家庭金融资产结构变迁互动关系研究——对机构投资者发展的一个理论解释

资本市场发展与家庭金融资产结构变迁之间的互动规律无法用简单的因果关系概括,从本质上说,两者是螺旋式前进、相互推动、相互促进的发展规律:家庭部门的决策变化作为需求力量推动了资本市场供给的变化;而资本市场供给本身,又引致了家庭部门多样化的金融资产需求。透过两者螺旋式前进的轨迹,我们提出了对机构投资者整合资本市场供给和家庭部门投资需求的功能解释,并提出了对我国机构投资者发展的政策建议。
