Equality of interest rates revisited: the multi‐country evidence

One influential aspect of international integration of financial markets is the possibility of reducing divergences between domestic interest rates and foreign interest rates or increasing the degree to which yields in different financial markets move together over time. In this study, we investigate the convergence of the real interest rates using the Kalman filter. Applying the modified Hall et al. () approach, we model the risk premium and convergence of real interest rates using the time‐varying parameter estimation techniques. We present evidence of risk premium and convergence for two blocks of countries—The Asian‐Pacific countries including the US, Japan, Taiwan and South Korea and the US‐European group including France, the UK, Germany and the US.     

Tests of different monetary aggregates for the monetary models of the exchange rate in five ASEAN countries

Although the real interest rate parity (RIRP) hypothesis has been extensively tested, there are no conclusive findings. We argue that the mixed findings are a result of the different methods used to calculate the real interest rate. In this article, we examine whether the RIRP holds for four OECD countries using five different methods for computing the real interest rate. The results indicate that the connection between real interest rates tends to be sensitive to the computational method of the real interest rate. Thus, authors have to be careful when comparing results across existing studies, since the type of computational method might be responsible for differences in conclusions of the validity of the RIRP.     

Currency Exposure to Downside Risk: Which Fundamentals Matter?

I study whether or not countries' macroeconomic characteristics are systematically related to their currencies' exposure to the downside market risk. I find that the currency downside risk is strongly associated with the local inflation rate, real interest rate and net foreign asset position. Currencies of countries with high inflation and real interest rates and negative net foreign asset position (debtor countries) are more exposed to the downside risk whereas currencies of countries with low inflation and real interest rates and positive net foreign asset position (creditor countries) exhibit “safe haven” properties. The local real interest rate has the highest explanatory power in accounting for the cross‐section of currency exposure to the downside risk. This suggests that the high currency exposure to the downside risk is a consequence of investments in high‐yield risky countries and flight from them in “hard times”.     

DO REAL INTEREST RATES REALLY CONTAIN A UNIT ROOT? MORE EVIDENCE FROM A BOOTSTRAP COVARIATE UNIT ROOT TEST

This paper re‐examines the empirical finding that international real interest rates usually have a unit root. This conclusion is put forth in Rapach and Weber (2004 ), using the Ng and Perron (2001 ) tests. We use Rudebusch's (1993 ) approach to construct the small sample distributions of the Ng and Perron tests, and calculate their asymptotic sizes, size‐adjusted powers and rejection rates. These numbers show that the lack of power in the Ng and Perron tests might account for the findings of Rapach and Weber (2004 ): that the unit root null cannot be rejected for most OECD countries. Size distortions are mild in the case of Ng and Perron tests for two series, but are serious for the Phillips and Perron Z‐test on inflation rates. We then apply a powerful covariate augmented Dickey–Fuller unit root test to examine the series for which stationarity cannot be determined with the Ng and Perron tests. The bootstrap technique is also used to control possible size distortions. In contrast to the results of Rapach and Weber (2004 ), the bootstrap covariate augmented Dickey–Fuller test yields striking evidence that real interest rates are stationary for 14 of 16 OECD countries, because nominal interest rates are stationary for the 14 countries, while inflation rates are stationary for all countries.     

Integration or Independence? An Alternative Assessment of Real Interest Rate Linkages in the European Union

The relationship between national real interest rates provides a valuable insight into the extent of economic and financial integration between countries. This paper tests for long‐run parity in ex post real interest rates among the major European Union (EU) countries over the period 1979–2003. The empirical investigation, however, is based on an alternative approach. Strong parity is determined by whether or not the first largest principal component (LPC), based on real interest rate differentials with respect to a chosen base country, is stationary. The qualitative outcome of the test is invariant to the choice of base country, and compared with alternative multivariate tests for long‐run parity, this methodology places less demands on limited data sets. Strong evidence of onshore parity occurs during 1979–1990 and 1993–2003 with the half‐life of a deviation to parity that varies towards 6 months. There is no evidence of long‐run parity among EU members during 1990–1993 despite the easing of remaining capital controls in 1990. Parity is rejected for a sample of non‐EU countries throughout the study period.     

A New Test of the Real Interest Rate Parity Hypothesis: Bounds Approach and Structural Breaks

The real interest rate parity hypothesis is tested using data for the group of seven industrialized countries (G7) over the period 1970–2008. The contribution is two‐fold. First, the paper utilizes the bounds approach in order to overcome uncertainty about the order of integration of real interest rates. Second, a test is made for structural breaks in the underlying relationship using a multiple structural breaks test. The results indicate significant parameter instability and suggest that, despite the advances in economic and financial integration, real interest rate parity has not fully recovered from a breakdown in the 1980s.     

Improving International Comparisons of Prices at Basic Heading Level: An Application to the Asia‐Pacific Region

The International Comparisons Program (ICP) run by the World Bank compares prices and real incomes across countries, and plays a pivotal role in the Penn World Table. Using a unique dataset consisting of over 600,000 price quotes from nine countries in the Asia‐Pacific region, we consider ways of improving the basic heading price indexes that form the building blocks of ICP. Current ICP methodology computes these price indexes using the country–product–dummy (CPD) method applied to the country average prices. We contrast this approach with: (i) a weighted version of CPD; (ii) CPD applied directly to the individual price quotes; and (iii) extended versions of CPD that include adjustments for unrepresentative products, urban–rural price differences, and different outlet‐types. Also considered are new CPD‐based methods for measuring urban–rural price differences, and the implications of our findings for the downward revision in China's GDP in ICP 2005.     

Strong dependence in the real interest rates

The stochastic behaviour of the real interest rates in ten European countries, Canada and the US is examined in this article by means of fractionally integrated techniques. Using a procedure, specifically designed for testing I (d) statistical models, the results show that the real interest rates are more persistent in some countries like France, Belgium or the USA than in others like the UK or Germany.     

Symmetric or Asymmetric Interest Rate Adjustments? Evidence from Southeastern Europe

The purpose of this paper is to examine how effectively the wholesale interest rates are transmitted to the retail rates and whether the interest rate passthrough is symmetric or asymmetric in Greece, Bulgaria, and Slovenia. The disaggregated general‐to‐specific methodology is applied for testing the symmetry hypothesis in these economies. It is evident from our results that variations exist across the countries examined regarding the monetary transmission process and the symmetry hypothesis alike. This can be interpreted as an indication of a different level of competition, development, and liberalization among the banking systems in these Southeastern European economies.     

Foreign interest rate shocks and exchange rate regimes in East Asia

Using a theoretical dynamic stochastic general equilibrium model and an empirical panel vector autoregression, we assess the transmission of foreign real interest rate shocks on the volatility of various key macroeconomic variables in nine small open economies in East Asia taking into account the role of exchange rate regimes. Both the theoretical and empirical findings confirm the hypothesis that flexible exchange rate may work as a shock absorber when the economy is hit by foreign real interest rate shocks. The findings suggest a clear trade-off between the volatility of real exchange rate and real output to foreign interest rate shocks, both the US and G7 real interest rates, where the responses of real output are mitigated in countries that have more flexible exchange rate regime.     

Mean-reversion in international real interest rates

This paper examines the mean-reversion property of real interest rates. Many past studies have reported puzzling outcomes of the mean-aversion of real interest rates for a number of countries. In the article, we employ panel unit root tests and carry out half-life estimation based on the bias-corrected bootstrap. These findings of the paper provide strong evidence that, in both major Western and East Asian capital markets (including several emerging ones), real interest rates are mean-reverting. In addition, we find evidence that the degree of mean-reversion of the real interest rates is positively correlated with that of output growth, which is consistent with the implications of standard intertemporal behavior.     

Current Account Imbalances and Real Exchange Rates in the Euro Area*

Global current account imbalances have been one of the focal points of interest for policymakers during the last few years. Less attention has been paid, however, to the diverging current account balances of the individual euro area countries. In this paper we consider the dynamics of current account adjustment and the role of real exchange rates in current account determination in the EMU countries. After controlling for the effects of income growth, we find the relationship between real exchange rates and current accounts to be substantial in size and subject to nonlinear effects. We find that real exchange rates can offer further insights, beyond the effects of the income catch‐up process, relevant to current account determination in the EMU.

Is high real interest rate persistence an intrinsic characteristic of industrialized economies?

Recent empirical findings show that post-war real interest rates are quite persistent and that they also contain a large number of structural changes in their means. In this study, we also find concurring results for real interest rates from thirteen industrialized countries. We show, however, that when the presence of various nonstationarities such as changing means is accommodated, some of the real interest rates exhibit substantially lower persistence or even become I(0). Our findings indicate that high real interest rate persistence is not necessarily an intrinsic characteristic of industrialized economies.     

The Role of Productivity and Financial Frictions in the Business Cycles of a Small Open Economy: Hong Kong 1984–2011

This paper analyzes the business cycle properties of the Hong Kong economy during the 1984–2011 period, which includes the financial crisis experienced in 1997/98 and the economic crisis of 2008–2010. We show that the volatility respectively, of output, of the growth rate of output and of real interest rates in Hong Kong are higher than the corresponding average volatility among developed economies. Furthermore, interest rates are countercyclical. We build a stochastic neoclassical small open‐economy model estimated with a Bayesian likelihood approach that seeks to replicate the main business cycle characteristics of Hong Kong, and through which we try to quantify the role played by exogenous total factor productivity (TFP) shocks (transitory and permanent), real interest rate shocks and financial frictions. The main finding is that financial frictions, jointly with the assumption that the country spread is endogenous, seem important in explaining the countercyclicality of the real interest rates.     

Real and nominal effects of monetary policy shocks

Abstract.  We employ the identification scheme of Kahn, Kandel and Sarig (2002) to analyse the impact of Canadian monetary policy on ex ante real interest rates and inflationary expectations. First, we decompose nominal interest rates into ex ante real rates and inflationary expectations using the methodology of Blanchard and Quah (1989) . Then we estimate a recursive VAR model with innovations in a monetary aggregate and the overnight target interest rate as alternative measures of monetary policy shocks. We find that a negative policy shock raises both nominal and ex ante real interest rates, lowers inflationary expectations and real industrial output, and appreciates the Canadian dollar.     

On the Transmission Mechanism of Monetary Constraints to the Real Side of the Economy

Contrary to the predictions of the theory underlying international finance, inflows of capital triggered by financial liberalisation have neither equalised real interest rates nor increased income growth in many emerging economies. We explain this puzzle by developing a model that combines the balance‐of‐payments constraint approach to economic growth with a less stringent version of the real interest rate parity hypothesis. The model’s foundations are based on robust empirical findings or well‐established macroeconomic models. We show that a perverse combination of income elasticities of demand for imports and exports generates slow income growth and high real interest rates. As domestic income grows and imports rise faster than exports, the real exchange rate is expected to depreciate in order to clear the balance of payments (or the foreign exchange rate market). An incipient capital outflow arises and interest rates increase. Faster adjustment in capital rather than in the goods market therefore generates a higher real interest rate differential between the domestic small open‐economy and the rest of the world. The long run analysis shows that a constant degree of risk aversion implies a positive equilibrium real interest rate differential that affects economic growth. A permanent increase in default risk driven by persistent current account imbalances thus impacts on long run growth. The model’s results are illustrated with evidence from the three major Latin America economies: Argentina, Brazil and Mexico.     

Democratization and Real Exchange Rates,

In this article, we combine two so far separate strands of the economic literature and argue that democratization leads to a real exchange rate appreciation. We test this hypothesis empirically for a sample of countries observed from 1980 to 2007 by combining a difference‐in‐difference approach with propensity score matching estimators. Our empirical results reveal a strong and significant finding: democratization causes real exchange rates to appreciate. Consequently, the ongoing process of democratization observed in many parts of the world is likely to reduce exchange rate distortions.     

The ‘real’ explanation of the PPP puzzle

This article shows that global financial markets cannot, by themselves, achieve net transfers of financial capital and real interest rate equalization across countries and that the integration of both global financial markets and global goods markets is needed to achieve net transfers of capital and real interest rate equalization across countries. Thus, frictions (barriers to mobility) in one or both of these markets can impede the net transfer of capital between countries, produce the Feldstein and Horioka (1980) finding of high-saving-investment correlations and prevent real interest rates from being equalized across countries. Moreover, frictions in global goods markets can explain why real exchange rates deviate from purchasing power parity (PPP) for extended periods of time and can therefore also explain the PPP puzzle. Consequently, we are able to resolve two of Obstfeld and Rogoff’s (2000) ‘6 major puzzles in macroeconomics’ with essentially the same explanation.     

The impact of thin‐capitalization rules on the location of multinational firms’ foreign affiliates

This paper examines how restrictions on the tax deductibility of interest cost affect location choices of multinational corporations (MNCs). Many countries have introduced so‐called thin‐capitalization rules (TCRs) to prevent MNCs from shifting their tax base to countries with lower tax rates. As of 2012, in our sample of 172 countries, 61 countries have implemented a TCR. Using information on nearly all new foreign investments of German MNCs, we provide a number of new and interesting insights in how TCRs affect the decision of where to locate foreign entities. In particular, stricter TCRs are found to negatively affect location choices of MNCs. Our results include estimates of own‐ and cross‐elasticities of location choice and also novel results on the relative importance of tax base vs. tax rate effects. We finally provide estimates for different uncoordinated as well as coordinated policy scenarios.
