从财政主导转向货币政策工具：中国利率水平决定的转变*

本文基于利率市场化的角度,使用马尔科夫体制转换自回归模型（MS AR）研究我国利率市场化改革以来（1996—2017年）利率水平决定机制的非线性变化。通过计量模型识别出我国利率水平决定的两个体制,即“财政主导”（1996—2005年）和“货币主导”（2006—2017年）。我国利率决定机制改变的时间轨迹与利率市场化改革进程的关键时间节点相吻合。这表明我国的利率市场化改革取得了显著成效,利率调控方式由财政主导转向货币主导,为进一步的利率市场化打下了良好的基础。     

中国货币政策利率传导机制有效性的实证研究

本文基于新颖的和交叉性统计数据,通过协整检验与Granger因果关系检验等方法,对中国货币政策的利率传导机制进行实证研究.实证分析结果表明:(1)我国货币政策的利率传导机制是低效的.(2)货币政策在整体上却有效.这从侧面可以证明:相比较于其他几个货币传导机制,我国的利率传导机制的阻塞效用更强,即其对货币政策总体绩效的贡献度相对最小.(3)利率传导机制还存在时滞效应.本文认为,解决目前我国利率传导机制低效性的主要方法还是要通过利率市场化的渐进推进.     

OPTIMAL INCOME TAXATION,DYNAMIC EFFICIENCY,AND THE SOCIAL COST OF PUBLIC EXPENDITURE*

An interest income tax and a publicly provided private good are introduced into the Hamada overlapping-generations model consisting of heterogeneous individuals where the government can use a wage-income tax, an identical lump-sum transfer, and the public debt. Two interesting problems are studied: (a) what relation exists between the optimal interest rate and the population-growth rate and (b) how dynamic efficiency affects the optimal-decision rules of taxes and the publicly provided good. We show that (i) if the government can (not) tax the interest income, then the optimal interest rate is (not) equal to the population-growth rate, (ii) without the availability of the interest tax the difference between these two rates is mainly caused by the income-distribution effect of the public debt and (iii) the dynamic efficiency effects on the optimal rules of the wage tax and the publicly provided good depend on not only such a difference but also the average substitute-complement relations among leisure, the second-period consumption and the publicly provided good.     

利率市场化视角下的货币政策风险承担渠道问题研究*

利率市场化进程的深入可能会对我国货币政策传导、金融稳定等产生不可忽视的影响。基于此,本文研究了利率市场化对货币政策风险承担渠道的影响。结果表明：（1）我国存在货币政策风险承担渠道,且从利率市场化间接度量的维度来看,在考虑以直接效应来衡量的贷款利率市场化之后,银行的实际风险承担水平上升;但是在考虑以价格约束效应来衡量的存款利率市场化之后,其效果并不明显。（2）从利率市场化直接度量的方法来看,直接引入虚拟变量的研究发现贷款利率市场化会使得货币政策对银行风险承担水平的影响变得明显;进一步从利率市场化综合度量的维度,引入整体的利率市场化指数的方法则发现,随着利率市场化进程的深入,银行的实际风险承担水平会上升。（3）利率市场化对货币政策风险承担渠道的影响在不同类型银行间存在差异。     

ASYMMETRIC PREFERENCES FOR INTEREST RATE VARIABILITY AND NON-LINEAR MONETARY POLICY INERTIA

Introducing in a central bank loss function asymmetric preferences for interest rate stabilization together with a (symmetric) smoothing goal could lead to asymmetric interest rate smoothing. An empirical analysis supports this theoretical result and finds for the disinflation (Volcker) period a more cautious adjustment of interest rates downwards than upwards, and for the 'price stability' (Greenspan) period a more inertial behaviour in the opposite direction.     

Monetary and banking policy transmission through interest rates: an empirical application to the USA,Canada, the UK and the Eurozone

The main purpose of this paper is an examination of the pass‐through interest rate transmission from the wholesale rates (central bank and/or money market rates) to the retail rates (deposit and lending rates) of the banking system. Knowledge of the transmission substantially helps us to calculate the pass‐through interest rate margin or mark‐up in the banking systems under examination (USA, Canada, the UK and the Eurozone). The selection of the wholesale interest rate is also an important part of this pass‐through transmission framework because it is related to the money supply process and therefore the central bank's policy capabilities. In the empirical part, a Johansen (1988) cointegration based error‐correction procedure (ECM‐GE) is implemented for the wholesale interest rate selection. Then an LSE–Hendry general‐to‐specific model (GETS) is applied, for the revelation of the banking sector pass‐through interest rate behaviour. In the empirical part, on the issue of the wholesale interest rate selection, the USA and the Eurozone seem to favour the Money Market rate while the UK and Canada favour the central bank policy rate. The results indicate two types of interest rate pass‐through behaviour, with market structure implication – namely, the US and UK banking systems contrasted with Canada–Eurozone.     

INTEREST AND INFLATION ACCOUNTING

This paper analyses the treatments proposed by Chapter XIX (Annex B) of the 1993 SNA and the manual Inflation Accounting published by the OECD (Peter Hill) as alternatives to the traditional recording of nominal interest. Real interest and interest prime (annex B) are relevant for different purposes. Their amounts are not the same to the extent that actual compensation and full required compensation for inflation differ. The recording of negative real interest is not compatible with the exclusion of holding gains/losses from the SNA current accounts. The accounting treatments in Inflation Accounting (capital transfers, additional lending/borrowing, no nominal holding gains/losses) and Annex B (nominal holding gains/losses, no capital transfers, no new lending/borrowing) are contrasted.     

THE TEMPORAL CAUSALITY BETWEEN FISCAL DEFICITS AND INTEREST RATES

Conventional wisdom suggests that higher government fiscal deficits cause higher (long-term) interest rates. Much empirical work—generally standard ordinary least squares (OLS) regression analysis—has examined this issue and has produced mixed findings. Even if these standard OLS studies conclude that deficits and interest rates are related, they do not answer the question of which came first—the higher deficit or the higher interest rate? A few studies have used Granger causality to consider the question of temporal causality, generally with short-term interest rates. Tliis paper employs the relatively new cointegration and error-correction methodology to reexamine the temporal causality between fiscal deficits and interest rates—both long term and short term. This study finds evidence that federal deficits cause the long-term interest rate.     

三种国债拍卖方式的拍卖收入比较研究

国债拍卖主要有美国式拍卖、荷兰式拍卖与混合式拍卖三种,但究竟哪一种拍卖方式的拍卖收入最大?学术界迄今尚无定论。文章对W-Z模型进行扩展,并在此基础上通过结合不同市场利率环境下投标者的不同风险偏好进行比较研究。结果表明:(1)当市场利率趋升时,若非竞争性投标量较大,则混合式拍卖收入最大;若非竞争性投标量较小,但竞争性投标者较少,且市场利率上升趋势极强,则同样是混合式拍卖收入最大,反之则荷兰式拍卖收入最大。(2)当市场利率趋降时,美国式拍卖收入最大。(3)当市场利率平稳时,何种拍卖方式收入最大无法确定。     

Post Keynesian endogenous money theory: A theoretical and empirical investigation of the credit demand schedule

The article investigates the relationship between interest rates and loan amounts provided by commercial banks from both a theoretical and an empirical perspective. Theoretically, some scholars belonging to the post Keynesian endogenous money tradition advocate that a decrease (increase) in interest rates leads to a positive (negative) effect on the amount of loans demanded by households and firms. On the other hand, some heterodox economists maintain that interest rates do not stimulate firms’ credit demand but that a certain degree of influence is allowed for loans provided to households. By applying a vector autoregression (VAR) and vector error-correction model (VECM) methodology to European Central Bank and Organisation for Economic Co-operation and Development data for the eurozone, this article proposes an empirical validation of such theoretical premises by analysing the relationship between the different types of credit provided by commercial banks and the corresponding interest rates. The main results show a negative relationship between the interest rates and the credit provided for the purchase of houses. Conversely, no significant relationship is found between loans granted to enterprises and loans for the purchase of consumption goods and the corresponding interest rates.     

Are there asymmetries in the response of bank interest rates to monetary shocks?

This article examines the velocity and asymmetry of the response of bank interest rates to monetary policy shocks. Using an asymmetric vector error correction model, it analyses the pass-through of changes in money market rates to retail bank interest rates in Italy in the period 1985–2002. The main results of the article are: (1) the speed of adjustment of bank interest rates to monetary policy changes increased significantly after the introduction of the 1993 Consolidated Law on Banking; (2) interest rate adjustment in response to positive and negative shocks is asymmetric in the short run, but not in the long run; (3) banks adjust their loan (deposit) rate faster during periods of monetary tightening (easing); (4) this asymmetry almost vanished since the 1990s.     

A realistic model for official interest rate movements and their consequences

This article extends the Vector Autoregression (VAR) methodology to examine the consequences of monetary policy decisions by considering two types of nonlinearities in the determination of official interest rates: (1) the asymmetry related to the different nature of the discrete and infrequent positive and negative interest rate movements determined by central bankers and (2) the convexity in the transmission of policy shocks induced by the nonnegativity constraint in interest rates. For the UK, we find some evidence of both types of asymmetries. In the US, responses to unexpected interest rate shocks are far more symmetric. Results highlight the importance of considering all types of asymmetries when studying monetary transmission.     

Interest Rate Pass-Through: Empirical Results for the Euro Area

Abstract. This paper empirically examines the interest rate pass‐through at the euro area level. The focus is on the pass‐through of official interest rates, approximated by the overnight interest rate, to longer‐term market interest rates, which, in turn, are a proxy for the marginal costs for banks to attract deposits or grant loans, and therefore passed through to retail bank interest rates. Empirical results, on the basis of a (vector) error‐correction and vector autoregressive model, suggest that the pass‐through of official interest to market interest rates is complete for money market interest rates up to three months, but not for market interest rates with longer maturities. Furthermore, the immediate pass‐through of changes in market interest rates to bank deposit and lending rates is found to be at most 50%, whereas the final pass‐through is typically found to be close to 100%, in particular for lending rates. Empirical results for a sub‐sample starting in January 1999 show qualitatively similar findings and are supportive of a quicker interest rate pass‐through since the introduction of the euro. It is shown that the difference between the adjustment speed of bank deposit and lending rates (typically around one versus three months since the common monetary policy) can to a large extent significantly be explained by credit risk considerations.     

Usury,Market Power and Poverty Traps: A Study of Rural Credit in 1930s’ China

This paper studies the cross-regional variation of interest rates in China in the 1930s. Based on county-level data from the Buck (1941) rural surveys, we examine factors that may have influenced rural interest rates in pre-1949 China. Since the quality of institutions that define property rights and facilitate contract enforcement is important for such transactions as land tenancy arrangements, we treat land tenancy rate (or percentage of owner-farmers) as a proxy for institutional quality. Contrary to the popular belief among historians and economists that usury or high interest rates caused persistent poverty, we find that while the monopoly-exploitation hypothesis has little explanatory power, a region’s institutional quality and income level are persistent and significant determinants of interest rates. Thus, poverty is a key driver of high rates of interest. Economic growth and the development of market institutions are crucial for lowering high interest rates and combating usury.     

Interest Rate Linkages between Offshore and Onshore Renminbi Markets

We examine the interest rate volatility spillover between the offshore and onshore Renminbi (RMB) markets. The Hong Kong inter‐bank RMB offer rate (CNY HIBOR) and the Shanghai inter‐bank offer rate (SHIBOR) are used, respectively, as the interest rates for the offshore and onshore RMB markets. The results of our research show that there was significant volatility spillover between the offshore and onshore RMB prior to 21 June 2013 and that direction of the spillover from the SHIBOR to the CNY HIBOR is stronger than that from CNY HIBOR to SHIBOR. However, the spillover declined in strength between 21 June 2013 and 20 April 2016. We also find that the interest rate correlations are low and unstable. Our research reveals that the offshore RMB interest rate has been an independent system that is not determined by the onshore market, and that the determination of the offshore RMB interest rate is very complicated. The Hong Kong market is increasingly playing a more important role in the determination of the RMB. This study contributes to our understanding of the interest rate determination in China and has important implications for policy makers in terms of interest rate policies in the offshore and onshore RMB markets.     

Budget deficits,short-term real interest rates and the specification of expected inflation: an empirical investigation

The purpose of this paper is to illustrate whether empirical estimates of the effects of budget deficits on short-term real interest rates are sensitive to the choice of the expected inflation variable. Survey data on expected inflation and the rational expectations method described by Mishkin (1981) are used to construct two measures of the short-term real interest rate. Results for two previous studies on this deficit-interest rate relationship are re-estimated using these measures of expected inflation and the interest rate variables. Additional results reported in this paper further indicate that empirical estimates of the interest rate effects of budget deficits are sensitive to the choice of the expected inflation variable. In addition to the choice of the inflation variable, a number of other robustness tests are included. We are able to conclude that (1) increases in budget deficits do not generally raise short-term real interest rates and (2) short-term real interest rates are not independent of the expected inflation variable.

The rate of interest is always based upon expectation, however little this may be justified by realization. Man makes his guess of the future and stakes his action upon it … Our present acts must be controlled by the future, not as it actually is, but as it appears to us through the veil of chance (Fisher, 1907, p. 213).     

Purchasing Power Parity and Interest Parity in the Laboratory

This paper analyses purchasing power parity and uncovered interest parity in the laboratory. It finds strong evidence that purchasing power parity, covered interest parity, and uncovered interest parity hold. Subjects are endowed with an intrinsically useless (green) currency that can be used to purchase another useless (red) currency. Green goods can be bought only with green currency, and red goods can be bought only with red currency. The foreign exchange markets are organised as call markets. In the treatment analysing purchasing power parity, the price of the red good varies. In a second treatment, the interest rate on red currency varies. In a third treatment, the interest rate on red currency varies, and the price of the red good is random.     

Stock returns and interest rates in China: the prequential approach

This article aims to study whether interest rates help to forecast stock returns in China using the prequential approach. A bivariate VAR model and a univariate autoregressive model are examined. Out-of-sample probability forecasts, generated based on both a bootstrap-like simulation method and a nonparametric kernel-based simulation method, are evaluated from both calibration (reliability) and sorting (resolution) perspectives. The results from calibration test indicate that including interest rates in the model improves the model’s ability to issue realistic probability forecasts of stock returns (be well-calibrated). Considering stock returns also enhances the prediction of interest rates with respect to calibration. Assessment through Brier score and Yates partition suggests that the model performs better in distinguishing stock returns that actually occur and stock returns that do not occur after incorporating the influence of interest rates. Overall, interest rates help in forecasting stock returns in China in terms of both calibration and sorting.     

The information content of the term structure: Evidence for Germany

This paper studies the usefulness of spreads between interest rates of different maturities as indicators of future inflation and real interest rates in Germany, using monthly data starting in 1967∶1. The central results are twofold. First, the interest rate spreads considered contain considerable information about future changes in inflation, but no information about the time path of real interest rates. Second, the medium-term segment of the yield curve (spreads between 6 and 2 year rates, for instance) appears to be the most informative for future inflation. These results are similar to those obtained by Mishkin (1990b) and Jorion and Mishkin (1991).     

Real interest rate parity with Flexible Fourier stationary test for Central and Eastern European countries

This study applies stationary test with a Fourier function proposed by Enders and Lee (2012) to test the validity of long-run real interest rate parity (RIRP) to assess the non-stationary properties of the real interest rate convergence for twelve Central and Eastern European (CEE) countries. We find that our approximation has higher power to detect U-shaped breaks and smooth breaks than linear method if the true data generating process of interest rate convergence is in fact a stationary non-linear process. We examine the validity of RIRP from the non-linear point of view and provide robust evidence clearly indicating that RIRP holds true for nine CEE countries. Our findings point out that their interest rate adjustment is mean reversion towards RIRP equilibrium values in a non-linear way.
