The credibility of standard instrumental variables assumptions is often under dispute. This paper imposes weak monotonicity in order to gain information on counterfactual outcomes, but avoids independence or exclusion restrictions. The outcome process is assumed to be sequentially ordered,...

Investment in East Germany is heavily subsidized. Econometric estimates based on a treatment approach show that the level of investment is significantly higher in firms being supported by state aid. Nevertheless, capital productivity is lower in East Germany, indicating a misallocation of...

Die Investitionstätigkeit in Ostdeutschland ist durch massive staatliche Förderung gekennzeichnet. Die mit Abstand wichtigsten Instrumente, hinsichtlich des Fördervolumens sowie der Inanspruchnahme durch die Betriebe, sind die Investitionszulage und die Gemeinschaftsaufgabe zur 'Verbesserung...
