SEARCH, Variable Sample Size, A Computational Solution

Morgan (1983) guaranteed that VSS dominated both FSS and SSR. But it is difficult to calculate the optimal sample size and the optimal reservation price both without recall and with full recall. As VSS without recall is a simplification of VSS with full recall, we will present on appendix a VB30 program that calculates only the full recall case. As known, on VSS, the search is sequential and in each period the sample size is variable. As normal, we will extract sellers prices from F(x) that is common knowledge, temporal horizon is T, goods are homogenous, no discount and consumer buys once just one unity of goods.
