Research

My main research interests are on Operations Management under Financial Frictions. Specifically, I study how the presence of financial frictions influence operational decision-making, operations strategies, and supply chain interactions. Within this area, my current research focuses on two topics: Supply Chain Finance and Managing Financially Constrained Operations.

Supply Chain Finance

My definition of supply chain finance includes all financing tools/arrangements that are between supply chain partners (e.g., trade credit, reverse factoring) or actively taking supply chain relationship/transaction into consideration (e.g., factoring, purchase order financing). This view is consistent with the recent definition of supply chain finance by the International Chamber of Commerce (ICC on SCF). My work in this area focuses on the operational implications of supply chain finance, and the optimal design of supply chain finance contracts.

Managing Financially Constrained Operations

Traditional operations management focuses on firms that are not financially constrained, or those whose financing cost can be captured by a single discount factor. For those firms, financial situation and operational decisions are not actively linked. However, when firms are financially constrained, their operational decisions and financial status can be highly inter-dependent. My works in this topic focuses on understanding such inter-dependence and its managerial implications.
