Cities increasingly address climate change, e.g. by pledging city-level emission reduction targets. This is puzzling for the provision of a global public good: what are city governments' reasons for doing so, and do pledges actually translate into emission reductions? Empirical studies have...

This paper analyzes the impact of declining extraction costs of shale oil producers on the choice of the policy instrument of a climate coalition in the presence of a monopolistic oil supplier such as OPEC. Shale oil producers' extraction costs represent an upper bound for the oil price OPEC can...

In the framework of the Paris Agreement implementation, financial transfers remain a major point of negotiation for addressing equity concerns raised by the ambitious climate objectives. In complement to the theoretical, experimental and numerical studies that have examined the role of transfers...

It is widely believed that an environmental tax (price regulation) and cap-and-trade (quantity regulation) are equally efficient in controlling pollution when there is no uncertainty. We show that this is not the case if some consumers (firms, local governments) are morally concerned about...

We develop a two sector incomplete markets integrated assessment model to analyze the effectiveness of green quantitative easing (QE) in complementing fiscal policies for climate change mitigation. We model green QE through an outstanding stock of private assets held by a monetary authority and...

The green paradox conveys the idea that climate policies may have unintended side effects when taking into account the reaction of fossil fuel suppliers. In particular, carbon taxes that will be implemented in the future induce resource owners to extract more rapidly which increases present...

This paper proposes a quantitative multi-sector DSGE model with bank failure and firm default to study the interactions between bank regulation and climate policy. Households value the liquidity of deposits, which are protected by deposit insurance. Banks collect deposits and issue equity to...

Does a shift to ambitious climate policy increase financial fragility? In this paper, we develop a quantitative macroeconomic model with carbon taxes and endogenous financial crises to study such "Climate Minsky Moments". By reducing asset returns, an accelerated transition to net zero exerts...

This paper builds on existing production network models to study the impact of global and sub-global carbon pricing. It uses the World Input-Output Database (WIOD) to calibrate intersectoral trade between seven regions and 56 economic sectors per region as well as EXIOBASE’s sectoral accounts...

Weitzman (2014) proposed that focusing international climate negotiations on a uniform carbon price is more effective than Paris style negotiations in achieving ambitious climate action. We put this hypothesis to an experimental test by simulating international negotiations on climate change in...
