Energy Transition Metals: Bottleneck for Net-Zero Emissions?

The energy transition requires substantial amounts of metals, including copper, nickel, cobalt, and lithium. Are these metals a bottleneck? We identify metal-specific demand shocks, estimate supply elasticities, and study the price impact of the transition in a structural scenario analysis. Prices of these four metals would reach previous historical peaks but for an unprecedented, sustained period ...

A Linear Reduced-Order Model for the Activated Sludge Process for the Integration into a Mixed-Integer Linear Energy System Optimisation Model

Conventional wastewater treatment plants consume significant amounts of electricity. The constant aeration of the wastewater in order to foster the growth of microorganisms or the pumping of wastewater are two examples for energy-intensive processes within a plant. Case studies have shown that switching off blowers and inlet pumps for a certain period of time is possible without a loss in water quality. ...

Access to Digital Finance: Equity Crowdfunding across Countries and Platforms

Financing entrepreneurship spurs innovation and economic growth. Digital financial platforms that crowdfund equity for entrepreneurs have emerged globally, yet they remain poorly understood. We model equity crowdfunding in terms of the relationship between the number of investors and the amount of money raised per pitch. We examine heterogeneity in the average amount raised per pitch that is associated ...

Equipping the Offline Population with Internet Access in an Online Panel: Does It Make a Difference?

Online panel surveys are often criticized for their inability to cover the offline population, potentially resulting in coverage error. Previous research has demonstrated that non-internet users in fact differ from online individuals on several sociodemographic characteristics. In attempts to reduce coverage error due to missing the offline population, several probability-based online panels equip ...

Chronic Disease Onset and Wellbeing Development: Longitudinal Analysis and the Role of Healthcare Access

Background Experiencing the onset of a chronic disease is a serious health event impacting living conditions and wellbeing. Investigating wellbeing development and its predictors is crucial to understand how individuals adapt to chronic illnesses. This study (i) analyzed the impact of a chronic disease on wellbeing development, and (ii) explored spatial healthcare access as potential moderating factor. ...

Adding Household Surveys to the Behavioral Economics Toolbox: Insights from the SOEP Innovation Sample

While laboratory and field experiments are the major items in the toolbox of behavioral economists, household panel studies can complement them and expand their research potential. We introduce the German Socio-Economic Panel’s Innovation Sample (SOEP-IS), which offers researchers detailed panel data and the possibility to collect personalized experimental and survey data for free. We discuss what ...

The EU Sustainable Finance Taxonomy and Its Contribution to Climate Neutrality

The EU Taxonomy is the first standardised and comprehensive classification system for sustainable economic activities. It covers activities responsible for up to 80% of EU greenhouse gas emissions and may play an important role in channelling investments into low-carbon technologies by helping investors to make informed decisions. However, especially in transition sectors much depends on the stringency ...
