This note proposes the continuous treatment approach as a valuable alternative to propensity score matching for evaluating
economic effects of merger and acquisitions (M&As). This framework allows considering the variation in treatment intensities
explicitly, and it does not call for an arbitrary definition of cutoff values in traded ownership shares to construct a binary
treatment indicator. We demonstrate the usefulness of this approach using data from European M&As and by relying on the example
of post-M&A employment effects. The empirical exercise reveals some heterogeneities over the whole distribution of acquired
ownership shares and across different types of M&As and country groups.
This survey summarises the state and development of European tax policy, in particular discussing the harmonisation progress
in direct as well as indirect taxes. Based on an overview over the theoretical and empirical literature on tax competition,
we further ask whether increased tax coordination is necessary to prevent a race to the bottom. We show that theoretical predictions
on the outcome of tax competition are ambiguous, and the empirical evidence in this regard is inconclusive as well. This,
in turn, gives rise to an only limited scope of stronger tax harmonisation.
