For the studies of wealth, inequality and poverty, the analysis of income distribution of the individuals is a crucial issue. In practice, however, only aggregated data are available, either in groups or as a few quantiles of the distribution. These may be stratified along characteristics like...

A semiparametric varying coefficient model is used to explore the heterogeneity in returns to export promotion across countries. Differences in characteristics of export-promotion agencies drive the heterogeneity in returns. Interestingly, characteristics that matter for export growth do not...

This article picks up the discussion on semi- and nonparametric generalized structured models by Mammen amp; Nielsen (2003). We introduce a general feasible estimator based on weighted smooth backfitting that can be used not only for most of the therein presented models. Moreover, we give...

The paper presents a study of the generalized partially linear model including random effects in its linear part. We propose an estimator that combines like-lihood approaches for mixed effects models, with kernel methods. Following the methodology of Hauml;rdle et al (1998), we introduce a test...

We introduce one-sided cross-validation to nonparametric kernel density estimation. The method is more stable than classical cross-validation and it has a better overall performance comparable to what we see in plug-in methods. One-sided cross-validation is a more direct date driven method than...

Consumer demand microdata typically exhibit a great deal of expenditure variation but not very much price variation. In this paper, we propose a semiparametric approach to the consumer demand problem in which expenditure share equations are nonparametric in the real expenditure direction and...

The question of whether empirical models are able to forecast the equity premium more accurately than the simple historical mean is intensively debated in the financial literature. The low prediction power is disappointing, even when using nonparametric models that make use of typical predictor...
