Abstract
Distortionary effects of inflation on relative prices are the main argument for inflation stabilization in macro models with sticky prices. Under indexation of non-optimized prices, those models imply a nonlinear and dynamic impact of inflation on the cross-sectional price dispersion (relative price or inflation variability, RPV). Using US sectoral price data, we estimate such a relationship between inflation and RPV, also taking into account the endogeneity of inflation by using two- and three-stage least-squares and GMM techniques, which turns out to be relevant. We find an effect of (expected) inflation on RPV, and our results indicate that average (“trend”) inflation is important for the RPV-inflation relationship. Lagged inflation matters for indexation in the CPI data, but is not important empirically in the PPI data.

Are Qualitative Inflation Expectations Useful to Predict Inflation?
Rolf Scheufele
Journal of Business Cycle Measurement and Analysis,
No. 1,
2011
Abstract
This paper examines the properties of qualitative inflation expectations collected from economic experts for Germany. It describes their characteristics relating to rationality and Granger causality. An out-of-sample simulation study investigates whether this indicator is suitable for inflation forecasting. Results from other standard forecasting models are considered and compared with models employing survey measures. We find that a model using survey expectations outperforms most of the competing models. Moreover, we find some evidence that the survey indicator already contains information from other model types (e. g. Phillips curve models). However, the forecast quality may be further improved by completely taking into account information from some financial indicators.

Inflation Expectations: Does the Market Beat Professional Forecasts?

No. 3,

Abstract
The present paper compares expected inflation to (econometric) inflation forecasts based on a number of forecasting techniques from the literature using a panel of ten industrialized countries during the period of 1988 to 2007. To capture expected inflation, we develop a recursive filtering algorithm which extracts unexpected inflation from real interest rate data, even in the presence of diverse risks and a potential Mundell-Tobin-effect.
The extracted unexpected inflation is compared to the forecasting errors of ten
econometric forecasts. Beside the standard AR(p) and ARMA(1,1) models, which
are known to perform best on average, we also employ several Phillips curve based approaches, VAR, dynamic factor models and two simple model avering approaches.

Inflation and Relative Price Variability in the Euro Area: Evidence from a Panel Threshold Model

Abstract
The impact of inflation on Relative Price Variability (RPV) generates an important channel for real effects of inflation. This article provides first evidence on the empirical relation between inflation and RPV in the euro area. Stirred by the widespread use of inflation caps or target bands in monetary policy practice, we are particularly interested in threshold effects of inflation. In line with the predictions of monetary search models, our results indicate that expected inflation significantly increases RPV only if inflation is either very low (below 0.95% per annum (p.a.)) or very high (above 4.96% p.a.).

Inflation and relative price variability in the euro area: evidence from a panel threshold model
Dieter Nautz, Juliane Scharff
Bundesbank Discussion Paper, No. 14/2006,
2006
Abstract
In recent macroeconomic theory, relative price variability (RPV) generates the
central distortions of inflation. This paper provides first evidence on the empirical
relation between inflation and RPV in the euro area focusing on threshold effects
of inflation. We find that expected inflation significantly increases RPV if inflation
is either very low (below -1.38% p.a.) or very high (above 5.94% p.a.). In the
intermediate regime, however, expected inflation has no distorting effects which
supports price stability as an outcome of optimal monetary policy.

Are Botswana and Mozambique ready for CMA enlargement?
Tobias Knedlik
Botswana Journal of Economics,
No. 3,
2006
Abstract
The paper elaborates on the appropriateness of a potentially enlarged Common Monetary Area in Southern Africa including Botswana and Mozambique. The theory of optimum currency areas including some extensions by accounting for costs of non-integration and considering the external relations of currency areas are presented. Various indicators such as the structure of the economies, interest rates, inflation rates, exchange rates, factor mobility and trading partners are observed empirically. The paper concludes that current changes in the exchange rate policy of Botswana are expected to lead to increasing, though already high, convergence with CMA countries. Botswana is therefore an appropriate candidate for CMA enlargement. Mozambique is converging towards South Africa but still remains on a lower level. Taking into account the costs of non-integration, however, the target of integration should be formulated for the medium term.
