International capital flows have increased dramatically since the 1980s, with much of the increase being due to trade in equity and debt markets. Such developments are often attributed to the increased integration of world financial markets. We present a model that allows us to examine how...

We consider an infinite horizon exchange economy with incomplete markets and default. As in Geanakoplos and Zame (1998) financial securities are traded if the promises associated with them are backed by collateral. The only collateral available in our economy are shares of Lucas trees. We prove...

This paper uses an asymptotically valid expansion to derive explicitly agent's individual demand schedules and then the equilibrium allocations in options. Agents derive financial and non-tradeable income over time; they can only partially offset the latter using bonds and stocks and the option...

We use the model to analyse reform proposals designed to encourage labour force participation at the lower end of the wage distribution. A special focus...
