Christina Roolfs is a member of the FutureLab: Public Economics and Climate Finance. She has studied mathematics, and Sustainability Economics & Management and is now doing her doctorate in economics at the nexus of climate policy and public economics.

Her focus is on the role of fiscal transfers and the coexistence of national and multinational carbon pricing policies. In her dissertation, she examines federal-like systems. She investigates, for instance, reform options for the European Union's Emissions Trading System depending on existing transfers and member states’ companion policies.

Christina Roolfs has several years of professional experience in the planning and operation of wind farms and photovoltaics (in particular feed-in resp. congestion management measures, direct marketing, and technical re-adjustments according to EEG amendments). She also worked on congestion management measures and multinational power grid planning using an analytical flow-based power pricing model as part of her master's thesis.

Current research interests

Fiscal federalism, multilevel policy, carbon pricing & transfer payments
Policy design and transfers in the European Union
