We establish the financial materiality of temperature variability by demonstrating its impact on US firms and investors. A long-short strategy that sorts firms based on exposure earns a market-adjusted alpha of 39 basis points per month. This variability metric is related to aggregate decreases...

Coastal flooding, exacerbated by sea level rise, is a considerable economic threat to low-lying regions. I investigate whether investors account and insure for this hazard by exploiting the heterogeneity of country exposure to current and future coastal floods. Using sovereign credit default...

Many economists and policy makers have long favored the use of a price instrument to control greenhouse gases because they are a stock pollutant and as such the marginal benefit of abatement is relatively flat. While the early literature on the problem is consistent with this view, the later...

In principle, linking emission trading schemes would favour the depletion of low-cost abatement opportunities that are geographically spread over the globe. However, this would only be possible if the price of the emission permits in the different schemes converge to one price. Using a simple...

This paper examines the key design mechanisms of existing and proposed cap-and-trade markets. First, it is shown that the hybrid systems under investigation (safety-valve with offsets, price floor using a subsidy, price collar, allowance reserve, and options offered by the regulator) can be...

We study investment and disinvestment decisions in situations where there is a time lag 0 from the time t when the decision is taken to the time when the decision is implemented. Applying the probabilistic approach to the combined entry and exit decisions under the Parisian implementation delay,...
