In this paper we study the effects of quality change on the price index for new passenger cars in Portugal for the years 1997-2001. Hedonic regression models are studied, giving particular emphasis to the relation between the form of the price index and the specification of the hedonic equation...

This note provides a structural interpretation for the index of price changes synchronization proposed by Fisher and Konieczny (2000, Economics Letters, 68, 271-277) and shows that it can be used to test the hypothesis of uniform staggering.

In this paper we critically reappraise some measures of the importance of time-dependent price setting rules and propose an alternative way to gauge the significance of this type of price setting behaviour. The merits of the proposed measure are highlighted in an application using micro-data....

In this paper we analyse the ability of time and state dependent price setting rules to explain durations of price spells or the probability of changing prices.Our results suggest that simple time dependent models cannot be seen as providing a reasonable approximation to the data and that state...

In this note we reappraise the measure of the importance of time-dependent price setting rules suggested by Klenow and Kryvtsov (2005, "State-Dependent or Time-Dependent Pricing: Does It Matter for Recent U.S. Inflation?," Bank of Canada Working Paper 05-4). Furthermore, we propose an...

This paper evaluates the effects of quality change on the price index for new passenger cars in Portugal for the years 1997-2001. Hedonic regression models are studied, giving particular emphasis to the relation between the form of the price index and the specification of the hedonic equation...

This paper proposes a test to check the specification of models with unobserved individual effects integrated out by quadrature and also a simple way of increasing the flexibility of this type of model. The results of a Monte Carlo study and an application using a well-known data set illustrate...

We show that the quantile regression estimator is consistent and asymptotically normal when the error terms are correlated within clusters but independent across clusters. A consistent estimator of the covariance matrix of the asymptotic distribution is provided and we propose a specification...
