We study (energy) markets with dirty incumbents and costly entry by clean producers. For intermediate entry costs, the market outcome exhibits inefficient production and inefficient entry. A policy mix of three popular regulatory instruments—taxation on polluters, feed-in tariffs for clean...

Urban renewal areas are popular but empirically understudied spatial planning instruments designed to prevent urban decline and induce renewal. We use a quasi-experimental research design to study the effects of 22 renewal areas implemented in Berlin, Germany, to increase housing and living...

We study optimal climate policy for a “policy bloc” of countries facing a market where emissions offsets can be purchased from a non-policy “fringe” of countries (such as for the CDM). Policy-bloc firms benefit from free quota allocations whose quantity is updated according to firms’...

Feed-in tariffs under the Renewable Energy Sources Act, the so-called Erneuerbare-Energien-Gesetz (EEG), have triggered a massive expansion of electricity from renewable energy sources in Germany over the last decade. The increase in non-competitive renewable power generation though went hand in...

It is frequently observed that the implementation of green policies is delayed compared to the initial announcement. Considering a setting with a representative monopolist extracting a non-renewable resource, we demonstrate that announcing a green policy, but then delaying its implementation, is...

We consider a two small open economies model with cross-border pollution that is generated from consumption. Within this framework we examine i) the non-cooperative equilibrium consumption taxes and compare them to when pollution is only local, ii) the cooperative equilibrium consumption taxes...

Carbon pricing regulates emission flows and collects rents from underlying fossil resource stocks. The resulting investment shift implies lower climate policy costs and improved welfare if capital is underaccumulated. We prove that under emission trading, such a beneficial macroeconomic...

Future market developments determine the fate of fossil fuel carbon currently conserved unilaterally. Dynamic fuel depletion naturally suggests leakage rates approaching 100%. Reasons for lower leakage differ from what limits rates in previous studies. Discounting reduces present-value leakage...
