Conditional heteroskedasticity is an important feature of many macroeconomic and financial time series. Standard residual-based bootstrap procedures for dynamic regression models treat the regression eroor as i.i.d. These procedures are invalid in the presence of conditional heteroskedasticity....

The present paper focuses on three questions: (i) Are heavy tails a relevant feature of the distribution of BUND futures returns? (ii) Is the tail behaviour constant over time? (iii) If it is not, can we use the tail index as an indicator for financial market risk and does it add value in...

This paper investigates whether the degree and nature of interdependence between the United States and the euro area have changed with the advent of EMU. Using real-time data, it addresses this issue from the perspective of financial markets by analysing the effects of monetary policy...

This paper presents evidence on the lag between monetary policy actions and the response of inflation in the euro area as a whole as well as in Germany, Italy and France. In line with previous findings for the US and the UK, results here show that this lag is longer than one year both in the...

In several studies, hedonic methods have been used successfully for the ex post assessment of the accuracy of inflation measurement. Most of those studies relate to high-tech products, with respect to which traditional methods of compiling price indices often fail. We apply hedonic methods to...

In this paper we propose an alternative to traditional hedonics for estimating new multiunit housing inflation, adjusting for quality changes. By relying on the within-site variation we control in a very general way for unobserved housing characteristics using site-specific effects. Precise...

The paper analyzes the problems of measurement of durable consumer prices posed by quality change. Theoretical price indexes are defined and used to analyze several empirical methods of estimation of quality adjusted price indexes. The paper shows that hedonic regressions and other quality...

An economy exhibits structural heterogeneity when the forecasts of different agents have different effects on the determination of aggregate variables. We study how different forms of heterogeneity in structure, forecasts and adaptive learning rules affect the conditions for convergence of...

The last consultative papers of the Basel Committee on Banking Supervision set the path for a future where a wealth of credit assessment sources may be available. New external credit assessment institutions and internal ratings-based assessments will be added to ratings of major international...

Full commitment in monetary policy leads to equilibria that are superior to those from optimal discretionary policies. Different types of reactions functions to implement and instrument rules to approximate full commitment have been proposed in the literature. We assess optimal reaction...
