This dissertation comprises a series of three essays that relate advances made to both theoretical and empirical issues in marketing. The first essay discusses the issue of endogeneity of market share and price in logit models and provides a theoretical procedure to solve this problem. The...

How should brand managers determine the optimal advertising budget to generate sales and maximize profit from multiple regions and over time? How much of it should be set aside for national advertising? How should they allocate the rest across multiple regions? This paper addresses these...

Though individual demand and supply equations can readily be expressed in logit models, closed-form solutions for equilibrium shares and prices are intractable due to the presence of products of polynomial and exponential terms. This hinders the employment of logit models in theoretical studies,...

Blood banks rely on marketing to encourage donors to give blood. Many, if not most, blood banks in the U.S. are community-based not-for-profit organizations with limited marketing budgets. As a result, blood banks increasingly use novel and inexpensive online media, i.e., paid, owned and earned...

The emerging meta- and multi-verse landscape is yet another step towards the more prevalent use of already ubiquitous online markets. In such markets, recommender systems play critical roles by offering items of interest to the users, thereby narrowing down a vast search space that comprises...

Extant models posit that awareness declines immediately and gradually after the cessation of advertising, whereas anecdotal evidence from managers suggests awareness stays constant for a while and then decays rapidly. This pattern arises because consumers remember advertisements for a finite...

Extant models assume that awareness decline commences instantly. In contrast, we incorporate the possibility that awareness declines with a delay due to the memory for advertisements. To this end, we use delay differential equations to understand the evolution of awareness in the presence of ad...
