Abstract: Dynamic pricing and price commitment for perishable product company with consumer strategic behavior and demand uncertainty is studied. A game model with incomplete information is proposed to analyze the Perfect Bayesian Equilibrium of the two competitive companies in the two strategies, and obtain the equilibrium prices as well as expected profits. Numerical experiments are given to compare the optimal allocations of the two strategies, and discuss the influence of the demand anticipation, the degree of consumers' strategy, and the buying intention of consumers on the equilibrium. It is showed that under the dynamic pricing strategy, when the market is in moderate competition, the greater the degree of customers' strategy, the greater the profit. Moreover, dynamic pricing is preferred over price commitment when the buying intention of consumers is moderate, and price commitment is better when the degree of consumers' strategy and the demand anticipation are both large or the degree of consumers' strategy is moderate.

Key words: demand uncertainty, consumer strategic behavior, dynamic pricing, price commitment
