In the paper a non-stationary ARCH model is defined and its relation with a heteroscedastic RCA model is presented. Further, estimation of unknown parameters in a non-stationary ARCH(l) is described under a special seasonal behaviour of time varying parameters. This procedure is compared with...

This paper introduces a new class of long memory model for volatility of stock returns, and applies the model on squared returns for BRICS (Brazil, Russia, India, China, and South Africa) countries. The conditional first- and second-order moments are provided. The CLS, FGLS and QML estimators...

This paper considers statistical inference for the heteroscedastic varying coefficient model. We propose an efficient estimator for coefficient functions that is more efficient than the conventional local-linear estimator. We establish asymptotic normality for the proposed estimator and conduct...

This paper compares generalized method of moments (GMM) and simulated maximum likeli- hood (SML) approaches to the estimation of the panel probit model. Both techniques circumvent multiple integration of joint density functions without the need to restrict the error term variance-covariance...

estimation mainly for the context of heteroscedasticity or high dimension, which are up-to-date topics of current econometrics …. We describe a modification of linear regression resistant to heteroscedasticity and study its computational aspects. For … a robust version of the instrumental variables estimator we propose an asymptotic test of heteroscedasticity. Further we …

Estimating binary choice models with endogeneity is of considerable importance in microeconometrics. The leading control function approach does not apply when the endogenous variable is binary. We propose a multi-stage estimation procedure for a heteroscedastic binary choice model with an...
