This paper extends our earlier analysis of interdependent security issues to a general class of problems involving discrete interdependent risks with heterogeneous agents. There is a threat of an event that can only happen once, and the risk this poses to any one agent depends on actions taken...

This paper extends our earlier analysis of interdependent security issues to a general class of problems involving discrete interdependent risks with heterogeneous agents. There is a threat of an event that can only happen once, and the risk depends on actions taken by others. Any agent's...

I establish an extension of the classical general equilibrium treatment of uncertainty about exogenous states to price uncertainty. Traders do not know the prices at which trade will occur, but have expectations over possible prices. They trade derivatives, price-contingent securities, to insure...

The paper studies a two-sector monetary economy with two factors of production, labor and capital. The industrial sector has increasing returns to scale, the consumption sector non-increasing returns. All firms maximize profits and markets clear. For each rate of return on capital the model...
