内容简介：

Optimizingadvertising budget allocation in the luxury fashion industry is an importantproblem. In this talk, motivated by real world practices, we consider a luxuryfashion firm serving a conspicuous market consisting of two groups of consumerswho influence one another. We investigate the optimal customer portfolios andbudget allocation problem using the mean-variance (MV) framework. Under the basicmodel in which all budget must be spent, we identify different scenarios andexplore the MV efficient frontier for each scenario. Interestingly, differentfrom the classic investment portfolio problem, we reveal that: (i) not allbudget allocations between the two groups of consumers are MV efficient, whichmeans that the efficient frontier is not continuous; (ii) in the presence ofsocial influence, diversification of customer portfolio does not always lead toa smaller variance, which counter-intuitively means that focusing on a singleconsumer group can reduce risk. We also prove that to maximize expected profit,the optimal strategy is to allocate all advertising budget to one group ofconsumers only (i.e. a polarized strategy). We illustrate analytically theimportance of identifying the right scenario for budget planning. Finally, weexamine the budget saving strategy in the extended model and uncover that therespective range of efficient solutions is smaller than the one under the allbudget spending strategy. This shows that the budget saving strategy offersless flexibility for MV efficient budget allocation.
