The effects of inflation uncertainty on interest rates: a nonlinear approach

In this article, we investigate the effects of inflation variability on short-term interest rates within a nonlinear smooth transition regression framework. The test results suggest that only the conditional mean of the inflation is a nonlinear process whereas the conditional variance is time variant but linear. Using the square root of conditional variance as a proxy for inflation risk, we estimate Fisher equation augmented with inflation risk. Although the estimated Fisher equations suggest that inflation risk reduces short-term interest rates, we find that the effects of inflation risk on interest rates are regime-dependent. Particularly, we find that the negative effects of inflation variability on nominal rates are greater in low-inflationary regimes when compared to high-inflationary regimes. On the other hand, it is found that both inflation and inflation uncertainty raise the expected inflation effect.     

On the real effects of inflation and inflation uncertainty in Mexico

We estimate an augmented multivariate GARCH-M model of inflation and output growth for Mexico at business cycle frequencies. The main findings are: (1) inflation uncertainty has a negative and significant effect on growth; (2) once the effect of inflation uncertainty is accounted for, lagged inflation does not have a direct negative effect on output growth; (3) However as predicted by Friedman and Ball, higher average inflation raises inflation uncertainty, and the overall net effect of average inflation on output growth in Mexico is negative. That is, average inflation is harmful to Mexican growth due to its impact on inflation uncertainty. (4) The Mexican Presidential election cycle significantly raises inflation uncertainty both during the year of the election and the year following the election which has correspondingly negative effects on output growth.     

Inventory accumulation and expectations of real income,inflation and interest rates

A model is developed and tested to relate three categories of inventory accumulation to expectations of real income, inflation and interest rates through anticipated real corporate wealth effects. Expected future inflation leads firms to accumulate more inventories in advance financing them by means of ‘liquid’ assets to offset an anticipated loss of real wealth. Expected increases in interest rates have an impact on inventory accumulation opposite to that of expected future inflation. Past wealth effects are also allowed for by means of the accelerator principle. Finally, the growth rate of real income generally has a signifiant influence on inventory accumulation.     

The effects of foreign shocks when interest rates are at zero

In a two‐country DSGE model, the effects of foreign demand shocks on the home country are greatly amplified if the home economy is constrained by the zero lower bound on policy interest rates. This result applies even to countries that are relatively closed to trade such as the United States. Departing from many of the existing closed‐economy models, the duration of the liquidity trap is determined endogenously. Adverse foreign shocks can extend the duration of the trap, implying more contractionary effects for the home country. The home economy is more vulnerable to adverse foreign shocks if the neutral rate is low—consistent with “secular stagnation”—and trade openness is high.     

Demand shocks,supply shocks and the cyclicality of real wages

The behaviour of real wages over the business cycle has received increasiing attention in recent years. The cyclicality of real wages constitues an important aspect of recent models of the business cycle. However,empirical studies undertaken to determine whether real wages are procyclical or countercyclical have reported conflicting findings. In thiis paper we use vector-autoregressions to analyse the cyclicality of real wages. We find that the source of the disturbance plays a decisive role in the cyclical behaviour of real wages. In particular, we demonstrate that a supply shock generates procyclical real wages,whereas a demand shock yields countercyclicality.     

Keynes, uncertainty and interest rates

Uncertainty plays an important role in The General Theory, particularlyin the theory of interest rates. Keynes did not provide a theoryof uncertainty, but he did make some enlightening remarks aboutthe direction he thought such a theory should take. I arguethat some modern innovations in the theory of probability allowus to build a theory which captures these Keynesian insights.If this is the right theory, however, uncertainty cannot carryits weight in Keynes's arguments. This does not mean that theconclusions of these arguments are necessarily mistaken; intheir best formulation they may succeed with merely an appealto risk.     

The relevance of supply shocks for inflation: the spanish case

A retrenchment in crossborder credit is under way, the product of both market forces and political pressure on international banks to lend at home (Economist, 2009). In addition, banks, particularly the largest, have also dramatically expanded their retail banking operations over the past few years (Hirtle and Stiroh, 2007). Our goal, in this article, is to study the effects of default risk on equity returns through bank interest margin management under a renewed focus on domestic retail banking, a trend often attributed to the stability of banking activities. Specifically, this article explores the determinants of optimal bank interest margins based on an option-based firm-theoretical model with multiple sources of structural breaks due to political pressure. The model demonstrates how capital regulation and political pressure on foreign lending return and risk conditions jointly determine the optimal bank interest margin decision. We show that a more stringent capital requirement is linked with lower equity return, but higher default risk of the bank in the return to domestic retail banking. An increased focus on the political pressure on foreign lending return is linked with higher equity return and default risk of the bank. It is also showed that an increased focus on the political pressure on foreign lending risk decreases the bank's equity return and default risk. We conclude that the return to domestic retail banking may be a relatively stable activity when the political pressure decision impacts only the expected risk of the bank's foreign lending and not the return.     

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).     

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.     

Accommodation,supply shocks,and sluggish real wages

This paper analyzes the policy dilemmas posed by supply shocks in a rational expectations model featuring sluggish real wages. A discrete time version of the model is used to calculate the variances for prices, wages, and output for alternative policy rules and speeds of adjustment for real wages. The conventional tradeoffs between output and price variability in the model do not always exist.     

On the constancy of real interest rates

In the context of a small structural model, we show that the autocorrelation and the variance of the ex ante real rate of interest can be uniquely estimated; the random forecasting errors need not confound the problem of identifying variations in the real rate.     

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.     

The effects of the monetary policy regime shift to inflation targeting on the real interest rate in the United Kingdom

This paper studies the effects of the monetary policy regime shift to inflation targeting on the stochastic properties of the real interest rate in the U.K. The empirical analysis suggests a constant mean of the real interest rate that shifts with the monetary policy regime change to inflation targeting in October 1992. The mean-reverting level of the real interest rate has decreased from 5.1% to 2.3% per annum with the change in monetary policy to inflation targeting. In addition, the shift in monetary policy regime to inflation targeting has reduced the volatility of the real interest rate and increased the persistence of real interest rate deviations from the mean. The results suggest that the central bank can affect the stochastic properties of the real interest rate through the choice of monetary policy regime over a long period of time.     

Risk-aversion and the term structure of real interest rates

The term structure of real interest rates is studied in the context of a consumption-based general-equilibrium model. It is shown that the expectations hypothesis is approximately satisfied for low interest rate volatility. Otherwise the term premia are generally positive.     

The time-varying effect of inflation uncertainty on inflation for Turkey

We investigate the effect of inflation uncertainty on inflation from January 1982 through March 2016 for Turkey by using the Stochastic Volatility in Mean model with time-varying parameters. Our empirical evidence from consumer price index (CPI) inflation suggests that the observed positive relationship between inflation and inflation uncertainty is not robust. This positive relationship diminishes after 2002. This finding is valid for all five subcomponents of CPI inflation; however, for Health Services, Transportation Services, and Recreational and Cultural Services, an inflation-positive association is reported after 2010.     

Tax rate effects on interest rates

This paper investigates empirically the effects of personal and corporate taxes on taxable interest rates. The results suggest that the effective tax rate of marginal investors in the Treasury bill market is that of households, as opposed to that of tax-exempt institutions or corporations.     

The behaviour of expected short-term real interest rates in the UK

The existence of persistent technical inefficiency offers the opportunity for a ‘free lunch’ not typically implied by the neoclassical theory of the firm. When external effects are related to the use of particular inputs, reduction of persistent technically inefficient levels of input use represents a means of reducing external impacts. An important example is found in agriculture where substantial environmental impacts are generated by particular inputs. Within this context, this paper considers the usefulness of data envelopment analysis (DEA) for estimation of potential input reductions and assessment of potential reductions of environmental impacts of agricultural inputs. An application for French cereal production provides estimates that indicate that substantial potential exists for reduction of input use and environmental impacts.
