Does current and future supply affect the market price of pemits? The answer should be positive as the market itself was created by the governments that also control the supply. However, governments themselves may be uncertain about the relation between supply and price and may go through a...

This paper analyzes the role of storage for economies facing the risk of a gas supply disruption. We characterize the optimal/competitive transitory dynamics (accumulation, drainage and target stock). We partially relax the irreversibility hypothesis, by extending the model in two directions:...

This paper assesses the impact of emission trading on short-term input demand as well as on long-term production decisions, tacking into account uncertainty in the polluting input price and abatement by input substitution. We find that firms decisions depend on the interplay between three...

We propose a model of seasonal gas markets which is flexibleenough to include supply and demand shocks while also consideringnatural gas as an exhaustible resource. Using US data, we estimate themodel’s structural parameters and test economically founded restrictions.We analyze, theoretically...

We model an economy that alternates randomly between abundance and scarcity episodes. We develop an original method to characterize in detail the structure of the Markovian competitive equilibrium. Accumulation and drainage of stocks are the main focuses. Economically appealing comparative...

We propose a model of seasonal gas markets which is flexible enough to include supply and demand shocks while also considering exhaustibility. The relative performances of alternative policies based on price caps and associated measures or tariffs are discussed. We illustrate with structural...
