    Options for Importing Green Hydrogen into Germany by 2030: Transportation Routes, Country Assessments and Implementation Requirements ; Analysis

    Whether or not Germany can be carbon-neutral by 2045 will also depend on whether hydrogen can be successfully utilised. The ramp-up of a green hydrogen economy which includes a substantial, industrial-scale supply of hydrogen by 2030 is an ambitious goal. The strong rise in the demand for green hydrogen and its synthesis products by industry (e.g. steel, chemical and glass industries), transport (shipping, ...

    Merger Remedies and Bargaining Power in the Coffee Market

    This paper analyzes a merger of large manufacturers with divestiture in the French coffee market. In contrast to previous approaches used to study the effects of upstream divestitures on prices and welfare, we model the vertical market structure. First, our results show that the standard policy recommendation to require divestiture to small recipient firms may not hold when asymmetric bargaining power ...

    Spatial Competition and Pass-through of Fuel Taxes: Evidence from a Quasi-natural Experiment in Germany

    This paper analyses the pass-through rates and their determinants of the temporary German fuel discount in 2022 at its start and its termination. Based on a unique dataset of fuel station characteristics and prices, we employ a Regression Discontinuity in Time (RDiT) methodology to estimate heterogeneous pass-through rates. Our main contribution is to identify the impact of horizontal and vertical ...

    Fusionskontrolle muss Verhandlungsmacht in Wertschöpfungsketten beachten

    Im Rahmen der Wettbewerbspolitik spielt neben dem Kartellverbot und der Missbrauchsaufsicht die Fusionskontrolle eine zentrale Rolle. Fusionen zwischen großen Herstellern beeinflussen typischerweise den Wettbewerb und müssen daher von den Wettbewerbsbehörden genehmigt werden. Dabei sind Entflechtungen, bei denen die fusionierenden Unternehmen Unternehmensbeteiligungen oder Marken abgeben müssen, eine ...
