The transition of the steel sector to carbon neutrality requires significant investment. In this study, we aim to better understand the scale of investment required for a transition to hydrogen-based steelmaking and the ability of listed steelmakers to finance this investment. First, we analyze how capital expenditures are estimated in the academic literature and compare them with reported investment ...

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 ...

The use of green hydrogen can support the decarbonization of sectors which are difficult to electrify, such as industry or heavy transport. Yet, the wider power sector effects of providing green hydrogen are not well understood so far. We use an open-source electricity sector model to investigate potential power sector interactions of three alternative supply chains for green hydrogen in Germany in ...

We examine how competition affects VAT pass-through in isolated oligopolistic markets as defined by the Greek islands. Using daily gasoline prices and a difference-in-differences methodology, we investigate how changes in VAT rates are passed through to consumers in islands with different market structure. We show that pass-through increases with competition, going from 50% in monopoly to around 80% ...
