We model the arrival of heterogeneous information in a financial market as a doubly-stochastic Poisson process (DSPP). A DSPP is a member of the family of Poisson processes in which the mean value of the process itself is governed by a stochastic mechanism. We explore the implications for...

How do capital income taxes affect household portfolio choice and growth? We" approach this question within the context of a stochastic model of a small open economy in" which taxes on income from domestic capital (equity) and foreign bonds affect household" portfolio choice, welfare and the...

We analyze the dynamics of a simple growth model in which production occurs with a delay while new capital is installed (time-to-build). The time-to-build technology is shown to yield a system of functional (delay) differential equations with a unique steady state. We demonstrate that the steady...
