Besley and Persson (2023) pioneer a political economy model of a green transition with changing preferences. Here we solve for the optimal policy intervention and find that the optimal tax on the polluting good starts high and is subsequently declining, to support the transition in preferences....

Eco-innovations are crucial for the mitigation of climate change effects. It is therefore important to know if the existing climate change regulations and carbon pricing are appropriate and sufficient to trigger such innovations. Besides government measures, the demand for carbon neutral...

Accounting for nearly 8% of global annual carbon dioxide (CO2) emissions, the cement industry is considered difficult to decarbonize. While a sizeable number of abatement levers for Portland cement production are technologically ready for deployment, many are still viewed as prohibitively...

The cost and revenue earnings potential of alternative power generation sources has shifted considerably in recent years. Here we introduce the concept of Levelized Profit Margins (LPM) to capture the changing unit economics of both intermittent and dispatchable generation technologies. We apply...

This paper estimates the effect of heterogeneous university funding stemming from the German Excellence Initiative on a regional firm’s probability to innovate by using a multi-valued two-way fixed effects difference-in-differences model. The estimations show that funding an additional...

We study the implications of services trade for firm innovation. Using a quasi-experimental shift-share design, we find that access to foreign knowledge-related services improves the innovativeness of domestic firms and complements their indigenously sourced R&D. To confront this evidence, we...

Public procurement accounts for 15 to 20 percent of global GDP and is considered an effective innovation policy. However, the detrimental effects of non-innovative public procurement - public procurement tenders awarded solely based on their price - on firm innovations have been largely...
