Global economic convergence and protection of the climate are both worthwhile goals. Yet, there is an inherent tension between them. Greenhouse gases are a waste product that is often emitted in the production process. Limiting such emissions therefore hampers the accumulation of income and...

We introduce a "smart" cap and trade system that eliminates the welfare costs of asymmetric information (“uncertainty”). This cap responds endogenously to technology or macroeconomic shocks, relying on the market price of certificates to aggregate information. It allows policy makers to...

We develop a 2-period emission trading model for a stock pollutant with demand shocks resolving over time. We find precise conditions for efficiency of a stabilization mechanism where cumulative available permits decrease with excess supply in early periods. Our model describes the stabilization...

"Prices versus quantities" (Weitzman 1974), a hugely influential paper, is widely cited (and taught) in current debates about the best policy to reduce greenhouse gas emissions. The paper's criterion for ranking policies suggests that technological uncertainty favors taxes over cap and trade....

We develop a dynamic regulation game for a stock externality under asymmetric information and future market uncertainty. Within this framework, regulation is characterized as the implementation of a welfare-maximization program conditional on informational constraints. We identify the most...

In the recent years North Macedonia and Serbia have been rated among top most polluted countries in the world. North Macedonia, being a candidate country since 2005 and awaiting a date to start negotiations for EU membership for more than ten years after receiving a positive recommendation to...
