PROPOSITION 1: for the subset of online registrants satisfying the minimally appropriate attributes specified by the searcher, the perfect small small fraction of time he allocates to functioning on more than one people of that subset may be the ratio for the utility that is marginal onto the expected energy acted on.
Equation (8) means that the perfect small small fraction of the time assigned to search (and hence to action) is an explicit function just of this anticipated energy regarding the impressions found while the energy regarding the minimal impression. This outcome can behaviorally be expressed.
Assume the search that is total, formerly symbolized by T, is increased by the amount ?T. The incremental search time could be allocated because of the searcher solely to looking for impressions, in other words.
