This paper introduces a new theory of market incompleteness based on the information transmission role of prices and its adverse impact on the provision of insurance in financial markets. We analyze a simple security design model which endogenizes not only the characteristics of each individual...

This paper analyzes a simple parametric model of endogenously determined incomplete futures markets, focusing on their role in allocating risk and transmitting private information.
