Relevant Degree Programs
Complete these steps before you reach out to a faculty member!
- Familiarize yourself with program requirements. You want to learn as much as possible from the information available to you before you reach out to a faculty member. Be sure to visit the graduate degree program listing and program-specific websites.
- Check whether the program requires you to seek commitment from a supervisor prior to submitting an application. For some programs this is an essential step while others match successful applicants with faculty members within the first year of study. This is either indicated in the program profile under "Requirements" or on the program website.
- Identify specific faculty members who are conducting research in your specific area of interest.
- Establish that your research interests align with the faculty member’s research interests.
- Read up on the faculty members in the program and the research being conducted in the department.
- Familiarize yourself with their work, read their recent publications and past theses/dissertations that they supervised. Be certain that their research is indeed what you are hoping to study.
- Compose an error-free and grammatically correct email addressed to your specifically targeted faculty member, and remember to use their correct titles.
- Do not send non-specific, mass emails to everyone in the department hoping for a match.
- Address the faculty members by name. Your contact should be genuine rather than generic.
- Include a brief outline of your academic background, why you are interested in working with the faculty member, and what experience you could bring to the department. The supervision enquiry form guides you with targeted questions. Ensure to craft compelling answers to these questions.
- Highlight your achievements and why you are a top student. Faculty members receive dozens of requests from prospective students and you may have less than 30 seconds to pique someone’s interest.
- Demonstrate that you are familiar with their research:
- Convey the specific ways you are a good fit for the program.
- Convey the specific ways the program/lab/faculty member is a good fit for the research you are interested in/already conducting.
- Be enthusiastic, but don’t overdo it.
G+PS regularly provides virtual sessions that focus on admission requirements and procedures and tips how to improve your application.

This thesis comprises three independent essays on supply chain management. In the first essay we collect data on 27,000 vertical relationships to study the importance of different channels of productivity spillovers between upstream and downstream firms. We explore the relative influence of two types of channels: endogenous and exogenous. The endogenous channel measures how a firm's productivity is affected by knowledge transfers (arising from collaboration and peer-mentoring). The exogenous channels measure the extent to which productivity is influenced by the partners' characteristics (e.g. geographic location, inventory turnover, financial leverage, etc.). We find that the endogenous channel is the primary source of spillovers. We also find that a firm's productivity is influenced more by the operational, than by the financial characteristics of its partners.The second essay unveils a previously unexplored role of business insurance in managing supply chain risk. We show that firms may strategically buy insurance purely as a commitment mechanism to prevent excessive free-riding by other firms. Specifically, we show that contractual incentives alone leave wealth-constrained firms with low incentives to prevent operational accidents, and firms with sufficient wealth with excessive incentives. Insurance allows the latter firms to credibly commit to lower effort, thereby mitigating the incentives of the wealth-constrained firms to free-ride. The third essay explores the interplay between public policy and risk management, when governments must strike a balance between safety and industry welfare. We focus on industries where operational accidents can be destructive and, as a result, where the cost of third-party liability is significant. Firms in these industries may be discouraged from entering the market as a result of these costs. If entry is inefficiently low, a social planner can incentivize firms through ex ante subsidies, which defray the costs associated with making operations safer, or ex post subsidies, which mitigate the financial damages caused by the accident. We demonstrate that when the social planner values reliability over market competition, it is optimal to offer ex ante subsidies alone. Conversely, when competition outweighs the benefits of reliability, a combination of ex ante and ex post subsidies is optimal.
This dissertation studies three topics in supply chain management. Consider a decentralized supply chain, where a manufacturer distributes products through competing retailers. Incentive conflicts among players often occur in such supply chains since the players have different objectives. This research seeks to help the manufacturer understand downstream retailers' incentives and provide managerial guidelines such as coordinating mechanisms and optimal strategies under existing contractual agreements.The first essay considers a manufacturer who distributes a product line (consisting of different product variants) through competing retailers. Due to the substitution between different product variants, as well as between different retailers, the incentive problems associated with distributing a product line are more complicated than that of distributing a single product. We characterize retailers' incentive distortions, and construct contracts that achieve channel coordination. Using numerical simulations, we study how the retailers' incentives and contracts are affected by underlying model parameters.The second essay investigates firms' incentives for transshipment in a decentralized supply chain. Transshipment price and the control of transshipment parameters are key factors that affect the manufacturer's and retailers' incentives for transshipment. We identify conditions under which the manufacturer and retailers are better off and worse off under transshipment. We also compare the decentralized retailer supply chain with one where the retailers are under joint ownership (a "chain store"). We obtain two surprising results. First, the manufacturer may prefer dealing with the chain store rather than with decentralized retailers. Second, chain store retailers may earn lower profits than decentralized retailers.The third essay examines the impact of a gray market on the firms in a decentralized supply chain. Under certain conditions, a gray market's positive effect, i.e., the demand generating effect, dominates the negative effect, i.e., the demand loss in authorized channels, and increases the manufacturer's profit. However, the manufacturer also can be hurt by a gray market. In some cases, the manufacturer can use the linear wholesale price to deter retailers from transshipping to a gray market. However, the deterrence may not always be successful, and the manufacturer needs to employ other approaches such as penalty terms to terminate a gray market.
