When the log-price process incorporates a jump component, realised variance will no longer estimate the integrated variance since its probability limit will be determined by the continuous and jump components. Instead realised bipower variation, tripower variation and quadpower variation are...

The asymptotic theories used to estimate the integrated variance using realised variance or multipower variation suggest that returns should be sampled at the highest possible frequency. This leads to a bias problem due to market microstructure effects that can completely invalidate the theory....

When high-frequency data is available, in the context of a stochastic volatility model, realised absolute variation can estimate integrated spot volatility. A central limit theory enables us to do filtering and smoothing using model-based and model-free approaches in order to improve the...

In this paper we do a statistical analysis of the Mexican Consumer Price Index microdata set to characterize the rigidities of the price setting process in the different sectors of the Mexican economy. The microdata set goes from July 2002 to December 2009. Broadly, results show that there...

This paper studies the dynamics of Mexican inflation by using a wavelet multiresolution analysis on 16 indexes of the Mexican Consumer Price Index. This enables us to estimate the long-term trend, seasonality, and local shocks of the inflation series, even when the series are non-stationary. The...

In this paper, we conducted a detailed statistical analysis of the behavior of the Mexican CPI price variations from May 2003 to August 2006. Different methodologies allowed identification of posible classification problems of the subindexes and inflationary pressures on specific items during...

We study the dynamics of the term-structure of interest rates in Mexico. Specifically, we investigate time variation in bond risk premia and the common factors that have influenced the behavior of the yield curve. We find that term-premia in government bonds appear to be time-varying. We then...
