Clean-up certificates bundle the permission to emit CO2 with the obligation for its removal. We show that demand for such certificates is determined by cost-saving technological progress, the discount rate and the length of the compliance period. Introducing extra clean-up certificates into an existing ETS reduces near-term carbon prices and mitigation efforts. In contrast, substituting ETS allowances with clean-up certificates reduces cumulative emissions without depressing carbon prices or mitigation in the near term. We calibrate our model to the EU ETS and identify reforms where simultaneously (i) ambition levels rise, (ii) climate damages fall, (iii) revenues from carbon prices rise and (iv) carbon prices and aggregate mitigation cost fall. For reducing climate damages, roughly half of the issued clean-up certificates should replace conventional ETS allowances. In the context of the EU ETS, a European Carbon Central Bank could manage the implementation of cleanup certificates and could serve as an enforcement mechanism.}, language = {en} } @techreport{BorckMulder2024, type = {Working Paper}, author = {Borck, Rainald and Mulder, Peter}, title = {Energy policies and pollution in two developing country cities}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {78}, issn = {2628-653X}, doi = {10.25932/publishup-63847}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-638472}, pages = {37}, year = {2024}, abstract = {We study the effect of energy and transport policies on pollution in two developing country cities.

Results are robust to how the wage is measured, as well as to various further robustness checks. More importantly, we find substantial differences between industries. While, for instance, in the manufacturing sector, the gender of the owner plays no role for the gender pay gap, in several service sector industries, like ICT or business services, no or a negligible gender pay gap can be found, but only when firms are led by female business owners. Businesses in male ownership maintain a gender pay gap of around 10 percent also in the latter industries. With increasing firm size, the influence of the gender of the owner, however, fades.

The SOEP allows for a direct mapping from individual circumstances to individual net wealth and for a detailed decomposition of net wealth inequality into a variety of circumstances; among them childhood background, intergenerational transfers, and regional characteristics. The ratio of inequality of opportunity to total inequality is stable from 2002 to 2019. This is in sharp contrast to labor earnings, where ex-ante IOp is declining over time.

We derive a new metric for the valuation of non-permanent carbon storage, the social cost of carbon removal (SCC-R), which embeds also the conventional social cost of carbon emissions. We show that the contribution of CDR is to create new carbon sinks that should be used to reduce transition costs, even if the stored carbon is released to the atmosphere eventually. Importantly, CDR does not raise the ambition of optimal temperature levels unless initial atmospheric carbon stocks are excessively high. For high initial atmospheric carbon stocks, CDR allows to reduce the optimal temperature below initial levels. Finally, we characterize three different policy regimes that ensure an optimal deployment of carbon removal: downstream carbon pricing, upstream carbon pricing, and carbon storage pricing. The policy regimes differ in their informational and institutional requirements regarding monitoring, liability and financing.}, language = {en} } @techreport{Nastansky2022, type = {Working Paper}, author = {Nastansky, Andreas}, title = {Gruppierung von Daten}, series = {Statistische Diskussionsbeitr{\"a}ge}, journal = {Statistische Diskussionsbeitr{\"a}ge}, number = {55}, doi = {10.25932/publishup-57272}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-572722}, pages = {26}, year = {2022}, abstract = {Dieser Beitrag beinhaltet einen Vergleich zwischen den Methoden der Topologischen Datenanalyse (TDA) und statistischen Clusterverfahren bei der Gruppierung von Daten.

However, critics fear this could divert other students from more profitable academic education. We study labour market returns to vocational education in England, where until recently students chose between a vocational track, an academic track and quitting education at age 16. Identification is challenging because self-selection is strong and because students' next-best alternatives are unknown. Against this back- drop, we leverage multiple instrumental variables to estimate margin-specific treatment effects, i.e., causal returns to vocational education for students at the margin with academic education and, separately, for students at the margin with quitting education. Identification comes from variation in distance to the nearest vocational provider conditional on distance to the nearest academic provider (and vice-versa), while controlling for granular student, school and neighbourhood characteristics. The analysis is based on population-wide administrative education data linked to tax records. We find that the vast majority of marginal vocational students are indifferent be- tween vocational and academic education. For them, vocational enrolment substantially decreases earnings at age 30. This earnings penalty grows with age and is due to wages, not employment. However, consistent with comparative advantage, the penalty is smaller for students with higher revealed preferences for the vocational track. For the few students at the margin with no further education, we find merely tentative evidence of increased employment and earnings from vocational enrolment.}, language = {en} } @techreport{HunoldPetrishcheva2022, type = {Working Paper}, author = {Hunold, Matthias and Petrishcheva, Vasilisa}, title = {Foreclosure and Tunneling with Partial Vertical Ownership}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {57}, issn = {2628-653X}, doi = {10.25932/publishup-56560}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-565601}, pages = {47}, year = {2022}, abstract = {We demonstrate how the incentives of firms that partially own their suppliers or customers to foreclose rivals depend on how the partial owner can extract profits from the target (tunneling).
