Stochastic saddlepoint systems: stabilization policy and the stock market

Article Abstract:

The existence of an equally geometric characterization for stochastic saddlepoint models is presented. The result of putting in stochastic shocks into a linear rational expectations model with saddlepoint dynamics produced by a forward-looking asset price is studied. The analysis is applied to fiscal stabilization policy where adjustments for public expenditures are performed only when GNP moves outside a threshold around a target level.

Controlling inventory when prices fluctuate randomly

Article Abstract:

The problem of optimally controlling a stochastic inventory process with randomly fluctuating control costs is considered. Numerical methods that may be able to solve this problem are presented and analyzed. The cost function resulting from the minimal feasible policy is computed and shown to be bounded. This provides evidence regarding the boundedness of the optimal cost function.

Optimal management of durable pollution

Article Abstract:

The problems faced by an incompletely informed regulator in inducing a firm producing durable pollution to adopt a socially optimal pollution management technology are discussed. The optimal pollution management policy and the regulatory contract of a firm are discussed.
