实际利率水平与经济增长关系研究

本文分两个阶段研究实际利率水平与经济增长之间的关系,发现1978年-1990年较高的实际存款利率水平降低了当期经济增长,反而推动滞后一期的经济增长;1991年-2005年,实际存款利率水平与经济增长呈正相关关系,实际贷款利率水平与经济增长呈负相关关系.     

利率、汇率调整对房地产价格的影响——基于理论与经验的研究

本文首先构建了适合我国国情的房地产价格与利率、汇率关系模型，然后利用该模型对我国12个城市房地产价格与利率、汇率的关系进行实证研究。研究结果显示，利率与房地产价格呈负向关系；汇率与房地产价格之间具有相同的变化趋势，与理论分析有较大差异，表明我国金融制度仍存在缺陷，逐步完善金融市场才能更好地发挥利率和汇率调节经济的功能。因此，我们认为房地产价格保持相对稳定是房地产业安全运行的关键，在完善的金融制度下正确的利率和汇率政策能在此方面发挥重要作用。     

Information Risk in TIPS Market: An Analysis of Nominal and Real Interest Rates

This study investigates the presence of information risk in two closely linked interest rate securities traded in separate markets: the nominal interest rate observed in the Treasury bond market and the real interest rate observed in the relatively new Treasury Inflation-Protected Securities (TIPS) market. We find that information flows unilaterally from the Treasury bond market to the TIPS market with a one-day lag. The information risk arising from asymmetric information flows may cause less informed traders to demand a higher rate of return (OHara, 2003). Our study provides an empirical explanation of why the TIPS yield has been relatively high throughout its nascent trading history.     

Real Interest Rate Parity: Long-Run and Short-Run Analysis Using Wavelets

In this article, long-run and short-run relationships among real interest rates in G-7 countries are empirically analyzed. The evidence suggests the existence of long-run relationships among these real interest rates. However, the long-run relationship is not an equality relationship. Short-run relationships are estimated using dynamic simultaneous equation models. They reveal that the real interest rates of non-U.S. G-7 countries react and adjust to long-run disequilibrium conditions. A more detailed analysis based on wavelet transform indicates the existence of both short-run and long-run relationships; however, strict interest rate parity does not seem to hold true.JEL Classification: C22, E43, G15     

U.S. Real Interest Rates and Default Risk in Emerging Economies

This paper empirically investigates the impact of changes in U.S. real interest rates on sovereign default risk in emerging economies using the method of identification through heteroskedasticity. Policy‐induced increases in U.S. interest rates starkly raise default risk in emerging market economies. However, the overall correlation between U.S. real interest rates and the risk of default is negative, demonstrating that the effects of other variables dominate the anterior relationship.     

Risk Premium Shocks and the Zero Bound on Nominal Interest Rates

Quantitative dynamic stochastic general equilibrium (DSGE) models often admit that the zero bound on nominal interest rates does not constrain (optimal) monetary policy. Recent economic events, however, have reinforced the relevance of the zero bound. This paper sheds some light on this disconnect by studying a broad range of shocks within a standard DSGE model. In contrast to earlier studies, we find that risk premium shocks are key to building quantitative models where the zero bound is relevant for monetary policy design. Other commonly included shocks, such as productivity, government spending, and money demand shocks, are unable to push nominal rates close to zero.     

A Simple Multi-Factor,Time-Dependent-Parameter Model for the Term Structure of Interest Rates

In this paper, we present a simple version of the Duffie and Kan model (1996). Our model can perfectly fit the yield curve and the volatility curve and further provide true closed form solutions to the pure discount bond price and its European contingent claims. Due to the specific factor structure in our model, the calibration exercise is easy to implement. This advantage will improve the computational efficiency in pricing American style claims.     

Optimal Monetary and Fiscal Policy with a Zero Bound on Nominal Interest Rates

I characterize optimal monetary and fiscal policy in a stochastic New Keynesian model when nominal interest rates may occasionally hit the zero lower bound. The benevolent policymaker controls the short‐term nominal interest rate and the level of government spending. Under discretionary policy, accounting for fiscal stabilization policy eliminates to a large extent the welfare losses associated with the presence of the zero bound. Under commitment, the gains associated with the use of the fiscal policy tool remain modest, even though fiscal stabilization policy is part of the optimal policy mix.     

Dynamic Relationship between Housing Values and Interest Rates in the Korean Housing Market

The goal of this study is to identify the long-term relationship between housing values and interest rates in the Korean housing market, using the cointegration test and spectral analysis. The result shows a long-term negative (–) equilibrium relationship between housing values and interest rates. Moreover, the Granger causality test for confirming the short-term dynamic relationship between these variables shows one-way causality from interest rate to the growth rate of housing values, while the transfer function model demonstrates concretely the causal structure of this relationship. These findings suggest that the interest rate adjustment policy in the Korean housing market can work very effectively and will contribute to forecasting the growth rate of future housing values.

Dynamic Linkages among Budget Deficits,Interest Rates and the Stock Market*

This paper examines the dynamic linkages among the federal budget deficit, interest rates and the stock market for the United States from 1960 to 2006. The empirical strategy includes vector autoregression (VAR) and Granger causality analyses. The results suggest that budget deficits negatively impact upon stock returns, which implies a violation of the Ricardian Equivalence Proposition. Further analysis shows a higher sensitivity of stock returns to corporate taxes than to public spending. Finally, it is shown that although taxes are relevant for corporate profits in the short run, budget deficits are important for the stock market in the long run.     

Interest Rates and Exchange Rate Movements: Analyzing Short-term Investments in Long-term Bonds

Tests of the uncovered interest rate parity (UIP) are subject to various data problems when long-term interest rates are applied: due to the long investment period, time intervals for measuring exchange rate movements are usually overlapping and therefore not independent. This shortfall can be prevented by considering short-term investments in long-term bonds instead of investments to maturity. This article analyzes the explanatory power of long-term interest rates with regard to 1- and 3-month exchange rate movements by relating return differences from 1- and 3-month investments in domestic and foreign 10-year government bonds to nine different exchange rates. From a Swiss perspective, there is only weak support for an interrelation between return differences and the corresponding exchange rate movements, whereas from a US perspective, the resulting estimates are much more in line with UIP.The reader may for instance consider Engel (1996) and Froot and Thaler (1990).     

实际股票收益率与通货膨胀率关系的实证研究

股票收益率与通货膨胀率之间的关系至今仍无定论.采用1991年1月到2011年8月的月度数据,运用VAR模型对我国的股票收益率与通货膨胀率之间的关系进行实证分析,结果发现不论是预期的通货膨胀还是非预期的通货膨胀与股票实际收益率都是负相关关系.表明费雪效应在我国不成立,股票并不是对冲通货膨胀风险的理想工具.     

Further Evidence on the Real Interest Rate Parity Hypothesis in Central and East European Countries: Unit Roots and Nonlinearities

This paper analyzes the empirical fulfillment of the real interest rate parity (RIRP) theory for a pool of central and east European countries. To do so, we apply the recently developed Ng and Perron (2001) unit root tests, which are corrected versions of existing unit root tests, and the Kapetanios et al. (2003) unit root test, which generalizes the alternative hypothesis to the globally stationary smooth transition autoregression model. We find evidence in favor of the empirical fulfillment of RIRP, particularly when taking into account the possibility of nonlinearities in the real interest rate differential.     

House Price Booms,Current Account Deficits,and Low Interest Rates

Domestic factors, such as credit and preference shocks, can explain the negative correlation between house prices and the current account in the U.S. and several other countries before the recent crisis. These shocks, however, cannot account for the fall of world real interest rates observed in the data. Expansionary monetary policy shocks in the U.S., coupled with exchange rate pegs to the dollar in emerging economies, are crucial to understanding the evolution of the real interest rate. Yet, monetary policy factors play virtually no role for house prices and the current account.     

Interest rates,inflation, and the Fisher effect in China

The paper estimates the relationship between the nominal Treasuries rate and inflation in China. The dynamic econometric analysis yields a preferred, automatically reduced, empirical model revealing a Fisher effect. But the results are sensitive to using different sub-samples encompassed in the decade-and-a-half period following the disassociation of Treasuries from the People’s Bank of China administered interest rates at the end of the 1990s.     

Interest Rates and Stock Prices: Evidence from Central and Eastern European Markets

We provide empirical evidence regarding the responses of Central and Eastern European capital markets to monetary policy via domestic and international short-term interest rate shocks. The analysis is conducted using a four-variable structural vector error correction model identified by means of permanent-transitory restrictions. The results indicate a noticeable effect of the international interest rate on stock market indexes in the cases of the Czech Republic, Hungary, Poland, and Romania. Since no monetary policy autonomy exists in Bulgaria, Latvia, and Lithuania, we find support only for the inverse relationship between foreign interest rate and stock index prices.

The impact of jump risks on nominal interest rates and foreign exchange rates

This article investigates the relationship between the nominal interest rate and inflation and also the forward exchange rate under a general specification of the underlying processes govering the foreign exchange rate. There are three distinct risks that affect the relation between the real rate of interest and the nominal rate namely, consumption risk, diffusion risk, and the existence of jump risks of inflation. Jump risks lower the nominal interest rate because of jump hedging of a nominal bond. The forward exchange rate depends on the expected depreciation of the domestic currency as well as these three risks. As the domestic jump risks increase, the domestic nominal interest rate decreases and the forward exchange rate decreases.
