A stochastic cash model with deterministic elements
- 16 Downloads
In this paper we present a simple model which gives a solution to a (one period) stochastic cash problem with a fixed cash outlay at the end of the period. We focus on the role of options as insurance contracts, as to value a constraint on the minimum cash level. It is argued that a cash level adjustment is optimal where the sum of the marginal cost of liquidity and the marginal insurance premium (options value) is zero.
