Models for the impact of all order book events
price impact market orders limit orders cancellations market microstructure order flow
2011/7/19
We propose a general framework to describe the impact of different events in the order book,
that generalizes previous work on the impact of market orders. Two different modeling routes can be consid...
On Prediction Errors in Regression Models with Nonstationary Regressors
accumulated prediction errors final prediction error least squares estimators random walk models.
2011/4/2
In this article asymptotic expressions for the final prediction error (FPE) and the accumulated prediction error (APE) of the least squares predictor are obtained in regression models with nonstationa...

Dynamic economic theories generalized spectral derivative model misspecifications
2011/4/2
Dynamic economic theories usually have implications on and only on the conditional mean dynamics of economic processes. Using a generalized spectral derivative approach, Hong and Lee (2005, Review of ...
Nonparametric Estimation Of Varying Coefficient Dynamic Panel Data Models
semiparametric dynamic NPGMM consistency asymptotic
2011/4/2
We suggest using a class of semiparametric dynamic panel data models to capture
individual variations in panel data. The model assumes linearity in some
continuous/discrete variables that can be exo...
Characteristic Function-Based Testing for Multifactor Continuous-Time Markov Models via Nonparametric Regression
Characteristic Function Markov models conditional distribution
2011/4/2
We develop a nonparametric regression-based goodness-of-fit test for multifactor continuous-time Markov models using the conditional characteristic function, which often has a convenient closed form o...

This paper considers the estimation and testing of a within-group two-stage least squares (TSLS) estimator for instruments with varying degrees of weakness in a longitudinal (panel) Data model. We sho...
Semiparametric Quantile Regression Estimation in Dynamic Models with Partially Varying Coefficients

2011/4/1
We study quantile regression estimation for dynamic models with partially varying coefficients so that the values of some coefficients may be functions of informative covariates. Estimation of both pa...

2011/3/23
Advanced inference techniques allow one to reconstruct the pattern of interaction from high dimensional data sets. We focus here on the statistical properties of inferred models and argue that inferen...
