我国商业银行流动性与外汇储备的协整性分析

以商业银行流动性和外汇储备之间的关系为研究对象，运用相关计量方法，证明了外汇储备是商业银行流动性的格兰杰原因。国有商业银行流动性过剩在很大程度上源于外汇储备的增长，并且商业银行流动性与外汇储备之间存在着比较稳定的长期均衡关系。

HYSTERESIS IN UNEMPLOYMENT REVISITED: EVIDENCE FROM PANEL LM UNIT ROOT TESTS WITH HETEROGENEOUS STRUCTURAL BREAKS

This paper applies the panel LM unit root tests with heterogeneous structural breaks in level by Im  et al. ( Oxford Bulletin of Economics and Statistics , 67 (2005), pp. 393–419) to re-examine the validity of hysteresis in the unemployment rates of 19 OECD countries. Our empirical findings are favourable to the stationarity of the unemployment rates, i.e., the unemployment hysteresis hypothesis is strongly rejected. Our results suggest that shocks to unemployment rates are temporary and soon converge when we control for breaks. A major policy implication of the study is that a fiscal or monetary stabilization policy would not have permanent effects on the unemployment rates of the 19 OECD countries.

The dynamic interactions among the stock,bond and insurance markets

This paper explores the lead–lag relationships and the dynamic linkages among stock, insurance and bond markets in the developed countries. This is the first empirical study which sheds light on the extent and magnitude of the association among these financial markets used by the Granger causality test of Toda and Yamamoto (1995), generalized impulse response approach, and generalized variance decomposition in a multivariate setting. Our empirical results illustrate that there are indeed various patterns of dynamic relationships. The direction of causality appears to differ across countries. While investigating these interactive relationships under unexpected shocks, there is a one-way significant influence between the life insurance premium and long-run interest rate. These empirical findings serve as valuable applications not only for investors to diversify their risk away as well as to earn the abnormal return, but also for policy-makers to allocate resources more efficiently.     

Purchasing power parity in transition countries: Old wine with new bottle

This study questions whether the long-run purchasing power parity (PPP) holds in the transition economies (Bulgaria, the Czech Republic, Hungary, Latvia, Lithuania, Poland, Romanian, and Russia) for the period from January 1995 to October 2011. We employ the Sequential Panel Selection Method (SPSM) procedure using the Panel KSS unit root test with a Fourier function, a novel approach to panel unit root testing. The SPSM approach classifies the whole panel into a group of stationary and non-stationary series and is able to account for structural breaks, nonlinearity, and cross-section dependence. The results indicate that the PPP holds true for more than half of these transition countries studied, with the exception of Hungarian, the Czech Republic and the Russia. The findings have important policy implications for the transition countries.     

Revisiting the labor supply effect of social security earnings test: New evidence from its elimination and reinstatement in Japan

We explore the labor supply effect of the social security earnings test in Japan on those aged 65–69 years through a combined examination of the elimination of the earnings test in 1985 and its reinstatement in 2002. We present evidence showing that the effects of changes in the earnings tests on the labor supply of the elderly are not symmetric, controlling for changes in the attributes of workers and firms. The repeal of the earnings test in 1985 did affect the earnings distribution of the elderly (especially for male), while its reinstatement in 2002 did not alter the earnings distribution.
