A national-champions-related industrial policy has become (again) en vogue among European politicians. Against this background, our work orders different types of national champions along the industry lifecycle. Different types of locally bound externalities appear along the lifecycle. In a...

When countries need to implement costly economic policy reforms, these often imply uncertainties about their effectiveness for the home country and their spillovers to other countries. We develop a model to show that under these circumstances countries implement too few or too many policy...

This paper shows how competition among governments for mobile firms can bring about excessive differentiation in levels of taxation and public good provision. Hotelling s Principle of Minimum Differentiation is applied in the context of tax competition and shown to be invalid. Instead, when an...

Tax enforcement can be prohibitively costly when market transactions and participants are difficult to observe. Evasion among market participants may reduce tax revenue and provide certain types of suppliers an undue competitive advantage. Whether efforts to fully enforce taxes are worthwhile...

We study the interaction between algorithmic advice and human decisions using high-resolution hotel-room pricing data. We document that price setting frictions, arising from adjustment costs of human decision makers, induce a conflict of interest with the algorithmic advisor. A model of advice...

This paper uses a discrete-time partial equilibrium model of the European Emissions Trading System (EU ETS) to analyze the impact of the recent reform on allowance prices. By including bounded rationality such as myopia or hedging requirements, we find that the Hotelling price path is no longer...

Cumulative emissions drive peak global warming and determine the safe carbon budget compatible with staying below 2oC or 1.5oC. The safe carbon budget is lower if uncertainty about the transient climate response is high and risk tolerance low. Together with energy costs this budget determines...

It is widely recognized that a cost-efficient way to achieve the climate targets of the Paris agreement requires investment in carbon capture and storage (CCS). However, to trigger sizeable investment in CCS the carbon price must exceed the historic carbon prices. This paper examines whether a...
