Anti-immigration sentiments have been extensively studied in recent years. Empirical studies showed that the out-group size together with the general economic condition of the host country determines the extent and the intensity of the anti-immigrant perception. While nearly all studies...

Organizational innovation has been shown to be favourable for technological innovation. However, the question of which organizational practices should be combined – and thus of their compatibility – remains unanswered. We here empirically investigate the complementarities between different...

This paper aims at proposing measures of polarization for the distribution of a variable when information on the latter is only ordinal. The measures proposed are borrowed from the recent literature on the measurement of segregation. An empirical illustration is given, based on the European...

The main objective of the paper is to analyse the local determinants of innovation in the Luxembourg metropolitan region. We are particularly interested in the impact of the local milieu and characteristics of firms. Our paper addresses two specific research questions. Firstly, we examine the...

We propose two semiparametric estimators of the dose-response function based on spline techniques. Under uncounfoundedness, the generalized propensity score can be used to estimate dose-response functions (DRF) and marginal treatment effect functions. In many observational studies treatment may...
