In the robust statistics literature, a wide variety of models have been devel- oped to cope with outliers in a rather large number of scenarios. Nevertheless, a recurrent problem for the empirical implementation of these estimators is that optimization algorithms generally do not perform well...

By using data collected through a survey containing newly enrolled student in Management Engineering at the University of Brussels, we show that even if all students do not come with the same chance of success at university, their working/studying behavior may lessen the burden of the past....

Intensification of university-industry interactions raises concerns about the potential negative impact it may have on the pace of scientific progress. This paper analyzes the relationship between academic patenting, research collaboration and quality of scientic output in a panel of 268...

This paper presents a quality index for patent systems. The index is composed of nine operational design components that help shape the transparency of patent systems and affect the extent to which they comply with patentability conditions. Seven factors are related to rules and regulations...

This paper investigates the interaction between corruption and infrastructure policy reforms. I construct a simple model to illustrate how both an increase in regulatory autonomy and privatisation may in uence the effect of corruption. This interaction is then analysed empirically using a panel...

Realized volatilities, when observed through time, share the following stylized facts: co–movements, clustering, long–memory, dynamic volatility, skewness and heavy–tails. We propose a simple dynamic factor model that captures these stylized facts and that can be applied to vast panels of...

This paper studies the role of non-pervasive shocks when forecasting with factor models. To this end, we first introduce a new model that incorporates the effects of non-pervasive shocks, an Approximate Dynamic Factor Model with a sparse model for the idiosyncratic component. Then, we test the...

In this paper we study the factors that influence both dropout and degree completion (4 or 5 years to earn a degree) at university using survival analysis. In particular, we apply the set of discrete-time methods for competing risks event history analysis described in Scott and Kennedy (2005)....
