This dissertation research is broadly in the area of retail merchandising. Uncertainty in consumer choice decisions results in demand uncertainty and temporary stockouts. These stockouts in turn impact consumer choice decisions. This research draws on the theory of discrete choice, originating...

We consider a revenue sharing contract in a supply chain, under price dependent demand. The demand is random and follows a multiplicative model. We show that the retail price that maximizes expected retailer profits, is higher than the price that would maximize profits if there was no demand...

We consider a quantity flexibility contract in a supply chain, under price dependent demand. The demand is random and follows a multiplicative model. We show that the retail price that maximizes expected retailer profits, is higher than the price that would maximize profits if there was no...

We propose a method for estimating substitute and lost demand when only sales and product availability data are observable, not all products are displayed in all periods (e.g., due to stock-outs or availability controls), and the seller knows its aggregate market share. The model combines a...

We consider a multi-supplier, single-manufacturer supply chain where each supplier sells a different component at varying quality levels. The manufacturer has to decide on which quality level to choose for each component, trading-off the total cost and total quality. Each supplier decides on a...

Many firms have enjoyed remarkable success using revenue-sharing contracts to improve supply chain performance. The video rental industry and its pioneering deal with movie studios is one such example. At the same time, other firms have struggled to make it work. What accounts for this...

We build a model to study the implications of utilization-based minimum earning regulations of the kind recently enacted by New York City for its ride-hailing providers. We identify the precise conditions under which a utilization-based minimum earnings rule causes marketplace instability, where...

We develop a theoretical model of optimal growth in two-sided markets. The model posits that market output (number of transactions) is a function of the stock of supply and demand. This market output is modeled using a homogeneous function, which can have increasing or decreasing returns to...

Ride-sharing platforms face a “productivity paradox”, where any efficiency gained through improved dispatch or pricing strategies will not benefit drivers or riders. We show that this is a limit of the traditional ride-hailing model, and a consequence of the Hall-Horton driver equilibrium...

We consider a company selling heterogeneous products with prices customized for each customer and the final price is set by negotiations between sales agents and customers. This type of pricing modality is referred to as customized pricing with discretion and commonly used in insurance, consumer...
