International linkages between short-term real interest rates

Whereas previous studies have focused on the causal relation between nominal interest rates, this paper examines causal relationships between real rates for the United States and six other countries. Based on evidence from our full sample we find that U.S. and foreign interest rates are not highly informative for one another. This would suggest that even if the United States is regarded as a large player in international financial markets this does not necessarily translate into the transmission of U.S. real interest rates to other countries. However, an examination of various sub-periods of our sample reveals that this conclusion may be sensitive to the U.S. monetary policy regime. We also report results for linkages between European countries which indicate that Germany provides some information on real interest rates in France and the United Kingdom, but not in Italy. An analysis of various sub-periods for the European countries show that the result for France is not robust, with German rates having an impact only in the first period through March 1983. This latter evidence does not provide strong support for the hypothesis that Germany's monetary policy plays a dominant role in the European Monetary System. In general, we would argue that domestic factors play a prominent role in determining real interest rates, quite independently from the influence of interest rates from abroad.     

Federal budget deficits and long-term interest rates in USA

We investigate whether the emergence of high inflation rates after 1965 and large budget deficits after 1980s caused the financial market agents to become more sensitive to the outlooks for inflation and budget deficits. Our approach is parametric and our models fully account for possible presence of ARCH effects in the data.Our results show a statistically significant positive link between the budget deficits and the slope of the yield curve which is more pronounced in the later sub-sample period. These results are in line with Reinhard and Sack [Reinhard, V., & Sack, B. (2000). The economic consequences of disappearing government debt. Brooking Papers of Economic Activity, 163–209] but in sharp contrast with Evans [Evans, P. (1985). Do large deficits produce high interest rates? American Economic Review, 7, 68–87] and Evans [Evans, P. (1987). Do budget deficits raise nominal interest rates? Journal of Monetary Economics, 20, 281–300].     

The time-varying behaviour of real interest rates: a re-evaluation of the recent evidence

A time-varying parameter model with Markov-switching conditional heteroscedasticity is employed to investigate two sources of shifts in real interest rates: (1) shifts in the coefficients relating the ex ante real rate to the nominal rate, the inflation rate and a supply shock variable and (2) unconditional shifts in the variance of the stochastic process. The results underscore the importance of modelling continual change in the ex ante real rate in terms of other economic variables rather than relying on a statistical characterization that permits only a limited number of discrete jumps in the mean of the process.

Budget deficits and stock prices: International evidence

The purpose of this research is to provide empirical evidence regarding deficits and their effects on stock prices. We investigate whether changes in deficits cause changes in stock prices and if so, in what direction. We use Granger causality tests and impulse response analysis of vector autoregressive models to assess the relationship between budget deficits and stock prices in several industrialized nations. The evidence from impulse response analysis and Granger causality tests shows that only in the U.S. deficit reductions have an inverse effect on equity returns.     

What do interest rates reveal about the functioning of real business cycle models?

This paper begins by documenting the extent to which the predictions of standard Real Business Cycle (RBC) models are incompatible with observed movements in real interest rates. The main finding of the paper is that extending the baseline model to include habit persistence in consumption and adjustment costs to capital significantly improves the model's empirical performance. In our evaluation of the model's performance, we take special care of estimating and testing predictions of the model using both moments drawn directly from the data and moments calculated after identifying shocks to the stochastic trend.     

Budget deficits and the current account balance: New evidence from panel data

This study examines two distinguishing predictions of the finite-horizon open-economy macroeconomic models regarding the effect of fiscal policy on the current account balance: (1) Given the path of government expenditures, a fall in public savings has an adverse effect on the current account balance, and (2) a bond-financed increase in government expenditures exerts a larger adverse effect on the current account balance than a tax-financed alternative. These predictions are vastly different from those of the Ricardian theory. According to this view, (1) lower public savings are met by equal increases in desired private savings, and thus the current account balance does not change, and (2) the response of current account balance to a change in government spending is independent of its financing methods. Empirical analysis of 63 countries is consistent with the conventional theory.     

Nominal interest rate policy rules and the feasibility of real interest rate control

In this paper the author builds a financial market model to demonstrate that policy aimed at reducing the variance in nominal interest rates reduces the information content of these variables. This has the undesirable effect of destabilizing real interest rates. The researcher demonstrates that nominal interest rate policy rules stabilize the component of the variance in the ex ante real interest rate attributable to the variance in the nominal rate. The variability of the expected inflation rate can, however, be increased by such policy rules, making the net effect of a nominal interest rate policy on the variance in the real interest rate ambiguous.     

Time-frequency co-movements between oil prices and interest rates: Evidence from a wavelet-based approach

This paper investigates time–frequency co-movements between crude oil prices and interest rates. To test this relationship, the study applied a continuous wavelet and cross wavelet approaches to data from West Texas Intermediate (WTI) crude oil prices and interest rates in the United States (U.S.). Results from the sample period revealed significant relationships, in the intermediate term, between WTI crude oil prices and U.S. interest rates. Moreover, co-movements between oil price and interest rate variables were especially sensitive during abnormal political events and periods of financial ‘meltdown’. We further use Partial Wavelet Coherence (PWC) and Multiple Wavelet Coherence (MWC) methods to investigate the impacts of five major control variables namely GDP growth, unemployment, three-month Treasury bill, CPI index and industrial production index. The results show a powerful impact of control variables on oil-interest rates co-movements under different frequencies. Finally, we show evidence of co-integrating long run relationship between oil markets and control variables. These results have important implications for energy investors and policy makers.     

Fixed versus floating: vulnerability to rising interest rates

• ? Looking at different economies' exposure to fixed‐ and floating‐rate private‐sector debt reveals how vulnerable they could be to rising interest rates. Our analysis finds that Hong Kong, Sweden, China and Australia are potentially most exposed via floating rates to rising debt service costs. A 150bp rise in rates would also push several other countries' debt service ratios above the peaks of 2008. Less vulnerable economies include the US and Germany.
• ? High levels of floating‐rate debt imply a large and rapid pass‐through of rising interest rates to firms and households, with negative consequences. Exposure to floating‐rate debt as a share of GDP varies greatly: the highest levels are in Hong Kong, China, Sweden, Australia and Spain, with the lowest levels in the US, France and Germany.
• ? Growing shares of fixed‐rate housing debt in the US, Eurozone and UK mean the impact of higher interest rates may be less severe than a decade ago. Private deleveraging in countries such as the US, UK and Spain could also soften the impact.
• ? A rise of 100bp in short‐term interest rates would raise the debt service ratio after one year by around 2.5% of GDP in Hong Kong, with increases of 1.5–1.7% of GDP in Sweden, China and Australia. The smallest effects would be in the US and Germany.
• ? A 100–150bp rate rise would push debt service ratios in China, Hong Kong, Canada, France and the Netherlands well above their peaks of a decade ago. A similar rate rise would take debt service ratios in Sweden, South Korea and Australia close to, or above, previous peaks.
• ? The distribution of debt within economies, which our analysis does not cover, is also important. For example, there is some evidence that the US corporate sector has a high concentration of debt among borrowers with weak finances. Countries that are highly vulnerable to interest rate rises may see their central banks normalise policy rates more slowly than they otherwise would.

     

Processes with volatility-induced stationarity: an application for interest rates

In this paper we propose a refinement of the existing definition of volatility-induced stationarity that allows us to distinguish between processes with drift and diffusion induced stationarity and processes with pure volatility-induced stationarity. We also propose a classification of stationary processes with volatility-induced stationarity according to the volatility that is needed to inject stationarity. Processes with volatility-induced stationarity are potentially applicable to interest rate time-series since, as has been acknowledged, mean-reversion effects occur mainly in periods of high volatility. As such, we provide evidence that the logarithm of the Fed funds rate can be modelled as a local martingale with volatility-induced stationarity.     

Convergence rates of recombining trees for pricing options on stocks under GBM and regime-switching models with known cash dividends

In the literature there appear various kinds of binomial trees for pricing options on stocks under geometric Brownian motions (GBMs) with known cash dividends. The aim of this paper is to compare the performance of the existing binomial trees in aspect of the convergence rates, which are usually used to measure precisely how fast the approximate values converge to the exact one, and to give a theoretical proof of the convergence rates for the interpolation binomial trees which are based on a model that excludes the arbitrage possibilities. Also the paper extends the studies to the regime-switching models with known cash dividend payment.     

Post-euro EU and US interest rates and foreign exchange rates: Are they in harmony or in disarray?

This paper focuses on: (1) how a select set of financial and economic factors could set the path for interest rates and foreign exchange rates, and (2) whether the resultant realized interest and exchange rates would be in harmony or in disarray. Using post-euro data for the EU and the US, an array of monetary rules is examined. In particular, the paper investigates whether the original and the extended Taylor rules provide an explanation of the dynamics of the EU monetary system since the inception of the euro. Our findings indicate that the EU and the US monetary responses are not the same and that exchange rates play a significant role.     

Real and nominal interest rates and the demand for housing

This paper is an empirical study of the relationship between inflation expectations and the demand for housing. The major findings are that housing demand is a function of both expected inflation and the real interest rate but that demand cannot be specified as a function of the nominal rate. It is also shown that expected inflation has a larger impact on those households that are likely to be constrained by capital market imperfections.     

The role of interest rates during the transition to a market economy

We construct a simple two period model of an economy in transition from being centrally planned to being market oriented. Using this model, we draw certain positive conclusions about economic policies that reduce distortions during the transition period. In particular, we focus on the role of interest rates, a market parameter that has previously been almost entirely ignored in planned economies. Using stylized data derived from Czechoslovakia, we show that increase in nominal interest rates can actually be welfare-improving by partially compensating for the distortions induced by the transition process.The model is sufficiently general to be applied to a number of transition economies, and we use the cases of Czechoslovakia, the USSR, and China as examples of some of the phenomena that we are trying to explain. We show that the model generates a constrained, suboptimal equilibrium. In particular, we see that raising interest rates during the transition period reduces repressed savings, brought about by shortages in the controlled market. An improvement in consumer utility can therefore be brought about.A large part of the work in this paper was carried out while I was a Visiting Scholar in the Research Department of the International Monetary Fund. I would like to thank Mario Blejer, Nadeem Ul-Haque, and Sweder Van Wijnbergen for helpful comments.

Technological change and the U.S. real interest rate

Economic theory predicts that the rate of technological growth exerts a positive influence on the real rate of interest. To test this hypothesis, I examine the relationship between the inflation-adjusted yield of the 90-day Treasury-Bill and two measures of innovation: the rate of growth of the stock of patents per worker and R&D spending relative to GDP. As theory predicts, from 1963 to 2008 the rate of interest responds positively to an increase in either measure. The point-estimates imply an elasticity of intertemporal substitution between one and two. The findings suggest that a change in the stance of monetary policy and a wave of innovation both contributed to the rise of real interest rates in the 1980s.     

Option-based risk management of a bond portfolio under regime switching interest rates

In the present paper, we assume an economy with regime switching short rates and show how the Value at Risk of a financial position on zero-coupon bonds, hedged by buying protective put options under budget constraints, can be minimized by selecting optimal (regime-dependent) strike prices.     

Testing the stabilization hypothesis in the UK short-term interest rates: Evidence from a GARCH-X model

The objective of this paper is to examine the validity of one of the recurring arguments made against futures markets that they give rise to price instability. The paper concentrates on the impact of futures trading on the spot market volatility of short-term interest rates. The analytical framework employed is based on a new statistical approach aiming to reconcile the traditional models of short-term interest rates and the conditional volatility processes. More specifically, this class of models aims to capture the dynamics of short-term interest rate volatility by allowing volatility to depend on both scale effects and information shocks. Using a GARCH-X and asymmetric GARCH-X model four main conclusions emerge from the present study. First, the empirical results suggest that there is an indisputable change in the nature of volatility with evidence of mean reversion after the onset of futures trading. Second, the information flow into the market has improved as a result of futures trading. Third, a stabilization effect has been detected running from the futures market to the cash market by lowering volatility levels and decreasing the risk in the spot market. Finally, trying to capture the leverage effect the findings suggest that positive shocks have a greater impact on volatility than negative shocks.     

Housing appreciation, mortgage interest rates, and homeowner mobility

This paper presents a model of the optimal timing of tradeup, which considers consumption and investment motives of homeownership. Households determine the optimal timing of trading up so as to maximize their intertemporal utility of both housing and nonhousing consumption. First we consider current homeowners, who already own a house and expect that they trade up to a more valuable house at some point in the future. Housing appreciation tends to induce an earlier optimal timing of trading up. Moreover, housing appreciation makes current homeowners better off in terms of welfare. However, current homeowners suffer from a rise in mortgage interest rates. Second, we consider first-time home buyers, who have decided to buy a house and expect to trade up to a more valuable house in the future. Their initial housing consumption is determined by an initial downpayment constraint. In this case, the effect of housing appreciation on the optimal timing of trading up is ambiguous and, unlike current homeowners, first-time home buyers suffer from housing appreciation. Moreover, as current homeowners, first-time home buyers suffer from a rise in mortgage interest rates. Most of the theoretical analytic results are ambiguous. Accordingly, we perform numerical simulations based on the theoretical model in order to determine the most likely comparative effects for a stylized set of parameters.As is apparent, the model captures the recent observations on homewner mobility and suggests that macroeconomic variables such as housing appreciation and mortgage interest rates effect the optimal timing of trading up and homeowner's welfare. Nevertheless, the model in this paper has several shortcomings, which should be the subject of future research. First, transaction costs are ignored. If transaction costs are incorporated, the lock-in effect from a rise in mortgage interest rates is well explained. However, the general analysis above is not altered in any essential way. Second, multiple moves are not considered in this model. Therefore, we concentrate on the timing of one tradeup as opposed to the timing and frequency of trading up. In a different vein, it would be interesting to test empirically the importance of the effects of macroeconomic variables on trading up by using microdata.
