Model specification and selection are recurring themes in econometric analysis. Both topics become considerably more complicated in the case of large-dimensional data sets where the set of specification possibilities can become quite large. In the context of linear regression models, penalised...

This paper applies component-wise boosting to the topic of regional economic forecasting. Component-wise boosting is a … combination with a large data set of monthly indicators, we show that boosting is generally doing a very good job in regional …, boosting outperforms our benchmark model for all the three regions considered. We also find that indicators that mirror the …

By using German industrial production for … selected by the boosting algorithm over time and four different forecasting horizons. It turns out that a number of hard … that never get chosen by the boosting approach at all. …

We propose a nonparametric method to test which characteristics provide independent information for the cross section of expected returns. We use the adaptive group LASSO to select characteristics and to estimate how they affect expected returns nonparametrically. Our method can handle a large...

We propose a nonparametric method to study which characteristics provide incremental information for the cross section of expected returns. We use the adaptive group LASSO to select characteristics and to estimate how they affect expected returns nonparametrically. Our method can handle a large...

Firm-to-firm connections in domestic and international production networks play a fundamental role in economic outcomes. Firm heterogeneity and the sparse nature of firm-to-firm connections implicitly discipline network structure. We find that a large group of well-established statistical...
