A curse of dimensionality arises when using the Continuum-GMM procedure to estimate large dimensional models. Two solutions are proposed, both of which convert the high di- mensional model into a continuum of reduced information sets. Under certain regularity conditions, each reduced information...

Several studies have highlighted the fact that heavy-tailedness of asset returns can be the consequence of conditional heteroskedasticity. GARCH models have thus become very popular, given their ability to account for volatility clustering and, implicitly, heavy tails. However, these models...

This article proposes an indirect method to validate existing estimates of immigrants? stock from the Spanish municipal population register, which some believe might be over-counting immigrants who double register in different municipalities or fail to deregister when leaving the country. The...
