Creativity is often highly concentrated in time and space, and across different domains. What explains the formation and decay of clusters of creativity? We match data on notable individuals born in Europe between the XIth and the XIXth century with historical city data. The production and...

We develop a dynamic regulation game for a stock externality under asymmetric information and future market uncertainty. Within this framework, regulation is characterized as the implementation of a welfare-maximization program conditional on informational constraints. We identify the most...

This paper reviews ex-post empirical assessments on the impact of carbon pricing on competitiveness in OECD and G20 countries in the electricity and industrial sectors. Most of these assessments find no statistically significant effects of carbon pricing or energy prices on different dimensions...

Denmark has a highly ambitious goal of reducing greenhouse gas emissions 70 percent below 1990 levels by 2030. While there is general agreement that carbon pricing should be the centerpiece of Denmark’s mitigation strategy, pricing needs to be effective, address equity and leakage concerns,...

In view of the challenges posed by climate change and the increase in climate targets by 2030 in the EU, as well as Austria's goal of achieving climate neutrality by 2040, the question of effective climate policy instruments is gaining in importance. The pricing of CO2, for instance in the form...

While environmental taxes aim at making environmentally harmful behaviour more costly, the opposite is true for environmentally beneficial tax incentives. Tax incentives imply foregone public revenues to favour less polluting consumption and investment activities in order to achieve...

I study how policymakers can access and act on the information about climate change damages that is dispersed throughout the economy. I analyze a new dynamic deposit-refund instrument (called "carbon shares") that I show can: i) efficiently price emissions conditional on information, ii)...

Carbon dioxide removal from the atmosphere is becoming an important option to achieve net zero climate targets. This paper develops a welfare and public economics perspective on optimal policies for carbon removal and storage in non-permanent sinks like forests, soil, oceans, wood products or...

Technology policy is the most widespread form of climate policy and is often preferred over seemingly efficient carbon pricing. We propose a new explanation for this observation: gains that predominantly accrue to households with large capital assets and that influence majority decisions in...

Jurisdictions adopt heterogeneous climate policies that vary both in terms of ambition and in terms of policy approach, with some jurisdictions pricing carbon and others subsidizing clean production. We distinguish two types of policy spillovers associated with diverse policy approaches to...
