Policymakers combine many different policy tools to achieve emission reductions. However, there remains substantial uncertainty around which mixes of policies are effective. This uncertainty stems from the predominant focus of ex post policy evaluation on isolating effects of single, known...

This paper assesses the potential impact of the European Union Emissions Trading System (EU ETS) on firm productivity. We estimate a stylized version of the neo-Schumpeterian model, which incorporates innovation and productivity catch-up as two potential sources of firm’s productivity growth,...

We exploit GPS-coded vehicle movement data that records millions of road users every second of their way over a full year in Berlin to suggest a novel approach to estimate the external costs of traffic congestion from revealed choices in a big data setting. To measure travel choices, we use...

This paper uses a novel GPS-coded dataset for more than three million car trips in the four largest German cities to measure the efficiency losses from using uniform fuel taxes as a second-best optimal tax to reduce traffic congestion. We estimate the short-run price elasticity of...

We study the effects of a large car scrappage scheme in Germany on new car purchases and local air quality by combining vehicle registration data with data on local air pollutant emissions. For identification we exploit cross-sectional variation across districts in the number of cars eligible...

This article explores how price linkages between carbon allowances and market fundamentals in the EU Emissions Trading Scheme (EU ETS) vary over time. I adopt a multivariate GARCH model that allows the conditional correlation between carbon, energy and financial prices to change smoothly across...

This paper assesses the carbon exposure of European electric utilities covered by the EU Emissions Trading System (EU ETS). First, we rely on an asset pricing model to empirically determine the effect of carbon price risks on firm-specific cost of capital for a sample of 20 European utility...

The price of EU allowances (EUAs) in the EU Emissions Trading Scheme (EU ETS) fell from almost 30€/tCO2 in mid-2008 to less than 5€/tCO2 in mid-2013. The sharp and persistent price decline has sparked intense debates both in academia and among policy-makers about the decisive allowance price...
