Real interest parity: Evidence from trade partnerships

This study investigates real interest parity (RIP) in trade partnerships, and whether RIP depends on the type of trade partnership, using short term interest rates and the Consumer Price Index (CPI) obtained from the Organization for Economic Cooperation and Development (OECD) database between 1975 and 2016. The investigation employs unit root and stationarity tests on interest rate differentials to study RIP between countries using Germany, United States, and Japan as base countries for selected countries in the European Union (EU), member countries of the North American Free Trade Agreement (NAFTA) and selected Asian countries respectively. The results show evidence in favor of RIP in the selected EU countries. The interest rate differentials of Belgium, France, Italy, Spain and the UK with respect to Germany confirms a long‐run relationship and real interest rate parity. There is also evidence to support the RIP in the other trade partnerships. With the exception of Mexico, the interest rate differentials for all the countries are stationary, and each quickly reverts to its mean.     

An examination of real interest rates in the United States, Canada, France, and Germany during the recent floating exchange rate period

This study reexamines the international linkage of ex-ante real interest rates using the theory of cointegrated processes. The univariate unit root tests suggest the existence of a nonstationary real interest rate in the United States, Canada, and (the former) West Germany. An ex-ante real interest rate is obtained by subtracting estimates of inflation from the nominal interest rate. The expected inflation rates are obtained by modeling changes in monthly CPI values as autoregressive moving average (ARMA) processes. A multivariate test for unit roots indicates that there are two cointegrating vectors, or one common stochastic trend, for the system of three nonstationary real interest rates. In addition, the log-likelihood ratio test fails to reject the null hypothesis that, in the long run, real interest rates in the United States are equal to those in Canada and West Germany.     

Evaluating capital mobility in the EU: a new approach using swaps data

The level of capital mobility prevailing within a group of core European Union (EU) countries is evaluated by means of cointegration-based tests of the covered interest parity (CIP). Unlike previous studies, this one concentrates on long maturities, investigating three to ten-year assets, and employing swap rates as a means of covering foreign exchange risk. Although CIP has not been previously assessed for EU long-term interest rates, such evaluation has practical interest. In fact, given EU member states' scarcity of mechanisms to react to asymmetric shocks, financial markets may become one major source of adjustment and stabilization. To this end, it is the mobility of long-term capital that is of critical importance. The analysis in this paper suggests that long-term financial flows appear to be completely unrestrained only between domestic Dutch and German markets.     

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     

Dynamic linkages among real interest rates in international capital markets

Short-run and long-run dynamic linkages among weekly real interest rates for G-10 countries are examined using a variety of time-series tests. These tests give special attention to the time-series properties of nominal interest rates, ex-ante expected rates of inflation and real interest rates. Term structure information is used to recover a theoretically consistent measure of ex-ante expected inflation. In-sample and out-of-sample Granger causality tests are also examined to evaluate lead/lag relationships among real interest rates. The results provide strong support for well-integrated markets, particularly in the long run. The results imply leadership roles for the US in international asset markets.     

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).     

Simple Banking: Profitability and the Yield Curve

How does bank profitability vary with interest rates? We present a model of a monopolistically competitive bank subject to repricing frictions and test the model's predictions using a unique panel data set on UK banks. We find evidence that large banks retain a residual exposure to interest rates, even after accounting for hedging activity operating through the trading book. In the long run, both level and slope of the yield curve contribute positively to profitability. In the short run, however, increases in market rates compress interest margins, consistent with the presence of nonnegligible loan pricing frictions.     

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.     

The Liquidity Demand for Corporate Property Insurance

This article suggests that liquidity may be an important reason for a corporation to purchase property insurance. A model of a risk‐neutral producer facing an endogenously determined risk of property damage under an output contract that penalizes underproduction is formulated to exemplify such a real need of liquidity. Under the output contract, the producer may purchase full unfavorable property insurance even when postloss financing is available. Surprisingly, the conclusion may still hold when the cost of postloss financing equals that of long‐term capital, provided that the rate of underproduction penalty is sufficiently high. Similar conclusions apply when postloss financing is replaced by planned internal reserve (self‐insurance) that may be invested in the short run at an interest rate that is lower than the long‐term cost of capital. When the capital market is perfect, however, the holding of planned internal reserve eliminates the purchase of actuarially unfavorable property insurance.     

Differential risk premiums and the UIP puzzle

We respecify the uncovered interest rate parity (UIP) conditions by inverting the market price of the risk (Sharpe ratio) formula. Our empirical model provides new insight indicating that violations to the UIP stem from the existence of a risk premium in the exchange rates and from observed market return differentials being a noisy statistic of the markets’ expected return differentials in our respecified model. Using an integrated macro‐micro structure framework for expected market return differentials improves our model fit and the validity of UIP.     

在岸与离岸人民币即期汇差的时变影响研究 ——基于修正的抛补利率平价模型的实证检验

基于修正的抛补利率平价模型,构建TVP-SV-VAR模型分析北向资金流动、人民币远期汇差、中美利差和中港利差对在岸与离岸人民币即期汇差的时变影响。结果表明：北向资金、人民币远期汇差以及中美、中港利差均对人民币即期汇差的短期影响最明显,中长期影响程度减弱;北向资金净流入增加、中美利差走阔和中港利差收窄会扩大人民币即期汇差;人民币远期汇差对人民币即期汇差的正向和负向影响交替发生。鉴于此,中国央行应当持续关注北向资金流向和流量、加强外汇市场沟通以及统筹和推动在岸和离岸人民币市场的良性协调发展。     

Financial integration in the pacific basin region: RIP by PANIC attack?

We exploit advances in panel data econometrics to test whether real interest parity holds in the Pacific Basin region. We test for a unit root in the difference between either the US, Japanese or Euro area real interest rate and the real interest rates from a panel of eleven Pacific Basin economies. Unlike extant studies that test for RIP using panel data, we use Bai and Ng’s (2004) PANIC test which allows for a very general model of cross-section dependence, including the possibility of cross-unit cointegration. Ignoring the possibility of cross-unit cointegration can lead to severe size distortions and to an over-rejection of the null hypothesis of a unit root. We overturn earlier findings based on first-generation panel tests, and demonstrate that cross-unit cointegration leads to incorrect conclusions. We find that RIP holds in the Pacific region. Real interest rates converge to the US rate. We find no support for the hypothesis that Pacific Basin real interest rates converge to either the Japanese or Euro area rates.     

The Relationship between Federal Deficits and Real Interest Rates

Real interest rates fluctuated a great deal since the 1970s. In the 1980s federal deficits accelerated and their impact on both nominal and real interest rates gained lots of attention. Based on monthly and quarterly data from January 1971 to December 1997 it is found that federal deficits had significant positive effect on the real interest rates: Personal income or consumption are found to have significant positive impact on the real interest rates, whereas expected inflation and money supply are found to have negative impact on the real interest rates. These findings are consistent with the conventional economic theory.     

Are Expected Inflation Rates and Expected Real Rates Negatively Correlated? A Long‐Run Test of the Mundell‐Tobin Hypothesis

Some empirical evidence suggests that the expected real interest and expected inflation rates are negatively correlated. This hypothesis of negative correlation is sometimes known as the Mundell‐Tobin hypothesis. In this article we reinvestigate this negative relation from a long‐term point of view using cointegration analysis. The data on the historical interest rate on T‐bills and the inflation rate indicate that the Mundell‐Tobin hypothesis does not hold in the long run for the United States, the United Kingdom, and Canada. We also obtain similar results using the real interest rate on index‐linked gilt traded in the United Kingdom.     

Negative real interest rates

Standard textbook general equilibrium term structure models such as that developed by Cox, Ingersoll, and Ross [1985b. “A Theory of the Term Structure of Interest Rates.” Econometrica 53 (2): 385–407], do not accommodate negative real interest rates. Given this, the Cox, Ingersoll, and Ross [1985b. “A Theory of the Term Structure of Interest Rates.” Econometrica 53 (2): 385–407] ‘technological uncertainty variable’ is formulated in terms of the Pearson Type IV probability density. The Pearson Type IV encompasses mean-reverting sample paths, time-varying volatility and also allows for negative real interest rates. The Fokker–Planck (i.e. the Chapman–Kolmogorov) equation is then used to determine the conditional moments of the instantaneous real rate of interest. These enable one to determine the mean and variance of the accumulated (i.e. integrated) real rate of interest on a bank (or loan) account when interest accumulates at the instantaneous real rate of interest defined by the Pearson Type IV probability density. A pricing formula for pure discount bonds is also developed. Our empirical analysis of short-dated Treasury bills shows that real interest rates in the UK and the USA are strongly compatible with a general equilibrium term structure model based on the Pearson Type IV probability density.     

Interest Rates and the Market for New Light Vehicles

We study the impact of interest rate changes on the demand and supply of new light vehicles in an environment where consumers and manufacturers face their own interest rates. Interest rate changes impact the auto market through both households and manufacturers. For the impact of rate changes on price and output growth, the household channel is quantitatively more important. A 100 basis‐point increase in both interest rates causes annual growth rates of production to fall from 1.0% to ?11.0% and sales to fall from 1.0% to ?2.9% in the short run.     

Natural Exchange Rate and Its Implications for the Purchasing Power Parity Puzzle

The notion of purchasing power parity has been an important building block in the theory of nominal and real exchange rates and for many theoretic models in international economics, leading to the purchasing power parity puzzle. The central issue of the puzzle is how to reconcile volatile short-term movements of real exchange rates (defined as nominal exchange rates adjusted for differences in national price levels) with very slow convergence to the parity condition. The main emphasis of this article is to show that the slow adjustment of the natural exchange rate is responsible for the well-known slow convergence of the real exchange rate to the long-run parity condition. The novel element of this article is to identify the relative importance between the financial channel and output gap channel of the purchasing power parity puzzle. The empirical findings of this article suggest that the financial channel is a dominant factor to explain persistent deviations of the real exchange rate from its long-run level.     

股票价格"虚拟"问题的研究

从现代市场经济的视角看,股票作为一种能够为投资者带来一定收入的资本所有权证书,是最典型的虚拟资本形式。作为虚拟资本的股票价格不外乎是一种与利息率相关的股息收入的资本化。由于利息率是股票价格一个决定性因素,致使股票价格与利息率相关性极强,而与其净资产的高低相关性较弱。因此,在证券市场上,股票价格往往高于其真实价格(每股净资产价值),从而具有了“虚拟”成分。这样,股票价格虚拟运动便成为一种独特的经济范畴。为此,只有注重对股票价格虚拟的合理范围的判断,确定出股票价格可投资的界限,才能以价值投资的理念,引导市场的投资行为,促进中国股市健康发展。     

Strategic Financial Management: Lessons from Seasoned Equity Offerings

Each of today's three dominant academic theories of capital structure has trouble explaining the financing behavior of companies that have seasoned equity offerings (SEOs). In conflict with the tradeoff theory, the authors’ recent studies of some 7,000 SEOs by U.S. industrial companies over the period 1970‐2017 notes that the vast majority of them—on the order of 80%—had the effect of moving the companies away from, rather than toward, their target leverage ratios. Inconsistent with the pecking‐order theory, SEO issuers have tended to be financially healthy companies with low leverage and considerable unused debt capacity. And at odds with the market‐timing theory, SEOs appear to be driven more by the capital requirements associated with large investment projects than by favorable market conditions. The authors’ findings also show that, in the years following their stock offerings, the SEO companies tend to issue one or more debt offerings, which have the effect of raising their leverage back toward their targets. Whereas each of the three theories assumes some degree of shortsightedness among financial managers, the authors’ findings suggest that long‐run‐value‐maximizing CFOs manage their capital structures strategically as opposed to opportunistically. They consider the company's current leverage in relation to its longer‐run target, its investment opportunities and long‐term capital requirements, and the costs and benefits of alternative sequences of financing transactions. This framework, which the authors call strategic financial management, aims to provide if not a unifying, then a more integrated, explanation—one that draws on each of the three main theories to provide a more convincing account of the financing and leverage decisions of SEO issuers.     

Why Money Growth Determines Inflation in the Long Run: Answering the Woodford Critique

Woodford argues that it is not appropriate to regard inflation in the steady state of New Keynesian models as determined by steady‐state money growth. Woodford instead argues that the intercept term in the monetary authority's interest rate policy rule determines steady‐state inflation. In this paper, I offer an alternative interpretation of steady‐state behavior, according to which it is appropriate to regard steady‐state inflation as determined by steady‐state money growth. The argument relies on traditional interpretations of the central bank's power in the long run and appeals to model properties that are common to textbook and New Keynesian analysis. According to this argument, the only way the central bank can control interest rates in the long run is via affecting inflation, and its only means available for determining inflation is by determining the money growth rate.
