This paper studies the evolution of hurricane insurance in Florida over the last decades. Hurricanes (and other natural catastrophes) are typically referred to as uninsurable" risks. The more exposed property owners find it difficult to obtain insurance cover from the private market and/or can...

Circular Economy literature recommends longer lasting products, in order to reduce pollution from extraction, production, and disposal. Our economic analysis finds conditions where consumers choose lives that are too short – a “durability gap”. Then policies targeting durability raise...

We derive exact conditions relating the distributions of firm productivity, sales, output, and markups to the form of demand in monopolistic competition. Applications include a new “CREMR” demand function (Constant Revenue Elasticity of Marginal Revenue): it is necessary and sufficient for...
