We study how the supply of environmentalism, which is defined by psychic benefits (costs) associated with the purchase of high-environmental (low-environmental) qualities, affects the way firms choose their prices and products and the ensuing consequences for the global level of pollution....

In recent years the land-rent gradient for the city of London has flattened by 17 percentage points. Further, teleworking has increased 24 percentage point for skilled workers, but much less for unskilled workers. To rationalize these stylized facts, we propose a model of the monocentric city...

We propose a general model of monopolistic competition, which encompasses existing models while being flexible enough to take into account new demand and competition features.
