摘要
Most research about keyword auctions without considering the budget constraint, but in the actual situation, the budget have some impact on advertiser’ s bid selection and profit. Based on this background, we es-tablish a keyword auction model in which display time is not fixed. Under the condition of a given budget, we studythe different changes about advertiser’ s profit when he raise and reduce his bid. In addition, we analysis the effect of budget on advertiser’ s profit, and prove the related conclusion. Numerical example results also verify the related theorem. The results show that advertisers’ bidscan not reach the Nash equilibrium with budget constraint when their budgets have given and there is no time limit.
