This study investigates the efficacy of public R&D support. Compared to most existing studies, we do not stop at substitution effects or general innovation outcome measures, but we are interested in knowing where the policy effect is highest: on innovation close to the market (i.e. incremental...

Untersuchungsgegenstand dieser Arbeit sind Euribor-Zinssätze, zwischen denen wir fraktionale Kointegrationsbeziehungen vermuten. Dazu klären wir im ersten Schritt den Begriff der fraktionalen Integration und stellen sowohl semiparametrische als auch nicht-parametrische Verfahren zur Bestimmung...

A test for time-varying correlation is developed within the framework of a dynamic conditional score (DCS) model for both Gaussian and Student t-distributions. The test may be interpreted as a Lagrange multiplier test and modified to allow for the estimation of models for time-varying volatility...

This study analyses the effectiveness of targeted public support for R&D investment. In particular, we test whether the specific policy design aiming at incentivizing (international)collaboration and R&D in small and medium-sized firms achieves the desired objectives on input as well as output...

Ce papier se propose de mettre en exergue les facteurs qui expliquent pourquoi des chefs de ménage maliens objectivement non pauvres se déclarent subjectivement pauvres. Pour ce faire, l’étude exploite des données de l’Enquête Légère Intégrée auprès des Ménages (ELIM 2006). Il...

This paper develops a criterion to assess equalization of opportunity that is consistent with theoretical views of equality of opportunity. We characterize inequality of opportunity as a situation where some groups in society enjoy an unfair advantage. In this context, equalization of...

This paper develops a nonparametric analysis for the sharp regression discontinuity (RD) design in which the continuous forcing variable may contain measurement error. We show that if the observable forcing variable contains measurement error, this error causes severe identification bias for the...

This paper frames growth incidence analysis within the logic of social impact evaluation understood as an assessment of variations in individual and social outcomes attributable to shocks and policies. It uses recentered influence function (RIF) regression to link the growth incidence curve...

Does after-school care provision promote mothers' employment and balance the allocation of paid work among parents of schoolchildren? We address this question by exploiting variation in cantonal (state) regulations of after-school care provision in Switzerland. To establish exogeneity of...

In this paper we present the asymptotic theory for spectral distributions of high dimensional covariation matrices of Brownian diffusions. More specifically, we consider N-dimensional Itô integrals with time varying matrix-valued integrands. We observe n equidistant high frequency data points...
