Asymmetric inflation dynamics: Evidence from quantile regression analysis

This paper applies the regression quantile approach developed by Koenker and Xiao (2004) to investigate the dynamic behavior of inflation in 12 OECD countries. By analyzing the behavior in a wide range of quantiles, this method allows us to quantify the influence of various sizes of shocks that hit the inflation, and is able to capture possible asymmetric adjustment of the inflation towards to its long-run equilibrium. It therefore sheds new lights on the inflation dynamics compared with the conventional unit root methodologies. Our results suggest that generally, the inflation rates are not only mean-reverting but also exhibit asymmetries in their dynamic adjustments, in which large negative shocks tend to induce strong mean reversion, and on the contrary, large positive shocks do not. Policy implications related to the empirical findings are also provided.     

Financial Development,Interest Rate Liberalization,and Macroeconomic Volatility

This article examines the relationship between financial development, interest rate liberalization, and macroeconomic volatility in fifty-six emerging and developed economies over the period 1980–2009. We find that financial development plays a significant role in dampening the volatility of macroeconomic growth rate, but up to a limit. The more the interest rate is liberalized, the more likely that financial development can stabilize the economy. Particularly, interest rate liberalization has a more positive influence on emerging and developing countries. Financial development and interest rate liberalization can also alleviate the influence of external shocks. They mutually enhance their functions as economic stabilizers.     

利率市场化背景下银行系统性危机的实证研究

从利率市场化的国际经验来看,无论是在发达国家还是发展中国家,其实施过程都容易导致不同程度的银行业危机。采用1973~2012年42个国家的面板数据,对利率市场化背景下的银行业危机进行的实证研究表明：利率市场化的推进将增加银行系统性危机发生的机率,特别是在存款利率市场化阶段,而严格的银行监管是抑制银行系统危机发生的有效方法;显性存款保险制度的设立无助于利率市场化后银行系统性风险的防范,甚至有可能会增加危机发生的机率;资本账户开放下进行利率市场化会增加银行系统危机发生的机率。利率市场化进程中允许开设民营银行不会增加银行系统危机的发生机率。     

上市公司可持续增长率偏差的实证分析

按照可持续增长率进行发展,要求企业全面权衡各方面的契约关系,以稳定的契约结构获取企业的长期增长。但是在现实中由于各种原因,企业不可能完全按照可持续增长率进行增长,出现了可持续增长率偏差。本文通过对我国A股市场的上市公司在1997-2005年的可持续增长情况进行分析,研究了我国上市公司可持续增长率偏差的主要影响因素及其对未来经营业绩的影响。研究结果表明：影响可持续增长率偏差的主要因素包括资产运作效率变动、资本结构的调整、外部权益融资和销售净利率的变化,鼓励政策对企业的可持续增长率偏差并没有显著作用。另外本文还验证了较高的可持续增长率偏差对后期（5年）的业绩提高具有消极作用。     

Macroeconomic stabilization through monetary and fiscal policy coordination: Implications for European Monetary Union

In a two-country model, we consider the implications of monetary and fiscal policy coordination for macroeconomic stabilization. We show that the optimal regime is one of monetary and fiscal policy coordination under flexible exchange rates. In the context of the European Community, this suggests that the desire to fix exchange rates may not be costless. In addition, we show that fiscal coordination requires a relatively high degree of flexibility in fiscal policy. This result suggests that limits on the flexibility of fiscal policies, as suggested in the Delors Report, may hinder macroeconomic stabilization.     

Riding the swaption curve

We conduct an empirical analysis of the term structure in the volatility risk premium in the fixed income market by constructing long-short combinations of two at-the-money straddles for the four major swaption markets (USD, JPY, EUR and GBP). Our findings are consistent with a concave, upward-sloping maturity structure for all markets, with the largest negative premium for the shortest term maturity. The fact that both delta–vega and delta–gamma neutral straddle combinations earn positive returns that seem uncorrelated suggests that the term structure is affected by both jump risk and volatility risk. The results seem robust for macroeconomic announcements and the specific model choice to estimate the risk exposures for hedging.     

Liquidity risk and policy options

On the basis of a liquidity management model, liquidity risks, defined as the probability of payment failures in a real-time gross settlement (RTGS) payment system, may either stem from liquidity management inefficiencies or insufficient cash balances. I will show that penalties charged on the amount of payment failures minimise liquidity risks without interfering with the bank’s technology preferences. I will instead show that liquidity requirements, although as effective as penalties to contain the risk of liquidity shortage, may distort the bank’s technology preferences and cannot stem liquidity management inefficiencies. I will also show that liquidity risks within RTGS payment systems are potentially smaller because they depend more on the liquidity management efficiency than on the randomness of cash inflows and outflows.     

居民货币需求的“结构性流动陷阱”及其对我国物价变动影响之研究

由于当前经济改革中的一些结构性问题使我国居民存在对货币需求的"结构性流动陷阱"."结构性流动陷阱"是我国近年来城乡居民储蓄存款高速增长的根本原因,也是对我国自1997年以来物价变动产生重要影响的一个基本因素.文章首先对当前转型期我国存在的居民货币需求"结构性流动陷阱"形成原因进行分析,其次,依据这个观点对我国近年来出现的通货膨胀和通货紧缩的基本原因和特点进行深入的分析和系统的研究,并就我国未来短期内物价走势进行分析和预测.
