The authors investigate the term structure of interest rates when the underlying state variables and production technologies follow the jump‐diffusion processes. Even in some cases where the traditional expectations theory about the term structure is consistent with general equilibrium under diffusion processes, the traditional theory is not consistent under jump‐diffusion processes. It is shown that bond prices are strictly higher under jump risks than otherwise and that consumers with logarithmic utility functions will develop hedge portfolios in the presence of jump diffusion.

This paper shows that the optimal policy for single-product periodic ordering systems with proportional holding and stockout costs and zero lead time is myopic for both stationary and nonstationary demand processes as described by Box and Jenkins. The proof of optimality is based on a theorem by Veinott showing that the myopic policy is optimal in each period if the beginning inventory for that period is less than the critical number which is the optimal policy for that period considered in isolation.
