In my dissertation, I propose a general research framework of MAD---Monitoring, Analyzing, and Data Informed Decision-making---for financial decision-making. I present three essays which concentrate on two consequential aspects of decision-making for financial risk management. The first two essays focus on better monitoring and analyzing the risk, and the last one focuses on better data-informed decision-making based on the observation and analysis. In the first essay, I study the modeling of joint mortality for the practice of life insurance and annuity pricing. Specifically, I develop a new mathematical model to describe the joint mortality for coupled dependent lives. This model can be used to guide the risk management strategy and the pricing policy for insurance and annuity products. It is shown that it improves the current methods for modeling financial decision-making related to dependent life structures (such as joint life insurance, last survivor annuities, and defined benefit plans for married couples). In the second essay, I study the prediction of Bitcoin price movement and the relevant implications for business analytics. I exploit Bitcoin transaction networks and link network characteristics with the Bitcoin market exchange price. Based on this linkage and the data record, I construct predictive models for Bitcoin price movement. With the innovative use of Bitcoin transaction network data, the predictive models lead to more accurate results which outperform existing models. This methodological innovation also presents new managerial insights from network perspectives. In the third essay, I focus on data-driven decision-making in contexts of the allocation of disaster relief funds. Specifically, I tackle methodological challenges in disaster management when data are extremely sparse and insufficient in the beginning of the disaster evolution, and slowly become more available and reliable as time unfolds. Here I propose an iterative learning method within the general MAD framework to estimate disaster damage losses using very limited and slowly obtained data. Results show that this iterative learning method leads to highly accurate results with fast convergence of the estimation error to a very low level. The framework and results of this essay can be further used for disaster management and resource allocation in various scenarios

The third problem investigates the concept of Industrial Symbiosis, a resource-sharing strategy among co-located firms to engage traditionally separate industries in a collective approach that involves physical exchanges of materials, water, energy and by-products. Inspired by a real-world example of a paper-sugar symbiotic complex, we study the impact on a firm's operational decisions from implementing an industrial symbiotic system. Our focus is on understanding how the introduction of competition and nature of competition will affect the firm's "willingness" to implement the symbiotic system.

This dissertation focuses on the role of dynamic information and incentives in service and manufacturing operations, where the information for decision making is often dispersed, privately held, and evolving dynamically over time. Below we briefly summarize each problem: In the second chapter, we examine how managers in intermodal marketing companies should use dynamic forecasting to coordinate daily operations, enhance efficiency and improve profitability. The problem arises from our collaboration with Hub Groups, the largest U.S. intermodal company. The study characterizes the effects of dynamic forecasting on profitability and policy choice. When it comes to profitability, dynamic forecasting reduces the need for carrying large stockpiles for an extended time, thereby saving on holding costs. It also ensures swift stock buildups for imminent shortages. With policy choice, dynamic forecasting guides policy formulation. As a testament, a variant of our model has been implemented by Hub Groups and delivered substantial performance improvement. In the third chapter, we examine the critical role of advance supply signals—such as suppliers financial health and production viability—in dynamic supply risk management. The firm operates a multi-class demand, multi-supplier inventory system. The sales are discretionary and suppliers are susceptible to both systematic and forecasting risks. We build a hierarchical Markov model to capture both the volatility and variability of advance supply signals, and use it to coordinate replenishment and selling. We show that the optimal procurement is driven by supply diversification and intertemporal substitution, the optimal selling is driven by customer segmentation and intertemporal rationing, and that they should be synchronized with dynamic forecast for adaptive and resilient risk mitigation. Interestingly, we find that demand heterogeneity may reduce the value of discretionary selling, that meanvalue-based forecast may outperform stationary-distribution-based forecast, and that taking more information into account need to always be better. This work is among the first to analyze the interplay of forecasting, procurement, and selling, thereby identifying the coordination role of signal-based forecasting in supply risk management. In the fourth chapter, we consider how dynamic information asymmetry and stochastic learning shape the contract design in long-term outsourcing. In this two-period problem, the supplier can reduce production costs through stochastic learning, but the learning outcome is his private information. This complicates the buyer’s contracting problem substantially, as now he must adjust price and production for both periods, properly balancing the benefit of learning and the cost of motivating the supplier. We demonstrate that the buyer may downward distort production in either period for the low type supplier, and not distort the production in either period for the high type supplier. This is driven by the interplay of the learning rate, information asymmetry, and intertemporal consideration. Thus, we can rationalize many outsourcing practices that cannot be explained by the existing adverse selection literature, where downward distortion is the norm. Moreover, the static long-term contract can only substitute the dynamic long-term contract when the learning rate is not substantial.

The third paper focuses on product recall decisions. We model the strategic interactions between the firms and the regulatory agencies. The important modeling aspects we consider are; two-sided uncertainty about whether the product is indeed defective, information asymmetry, where the firm is better informed about the product, and unreliable investigations by which both the agency and the firm can learn about the defect.

In today's globally competitive marketplace, organizations are challenged to increase their levels of customer service while under pressure to simultaneously reduce operating costs and the time to market of products and services. In meeting these challenges, organizations have adopted performance measurement systems to gauge current performance and to set benchmarks for improving future performance. As discussed in Neely et al. (1995), managerial success in improving performance is perquisite on having a formal performance measurement system that provides management with meaningful short term (day-to-day) as well as long term performance goals. Within the operations and supply chain management literatures the importance of integrating performance measurement systems into decision making has been addressed by many researchers (see for example, Ramaa et al., 2013; Martin & Patterson, 2009; Shepherd & Gunter, 2006; Gunasekaran et al. 2004). For effective performance measurement, formal quantitative models for performance measurement are needed (Suwignjo et al., 2000; Bititci et al., 2001). In this dissertation, we examine three different classes of performance evaluation models, which are used by decision makers in operations and supply chain management. The general forms of these three classes of models are: i) learning-based models for continuous improvement, ii) stochastic inventory models for shortages, and iii) cost-volume profit models for decision analysis. Despite a vast supporting literature for each class of model, there are adaptations of these models that can lead to further contributions that will be of interest to both the academic and practitioner communities. In the research of improving supply chain delivery performance, Guiffrida & Nagi (2006) developed a cost-based delivery performance model whereby improvement in delivery performance is achieved by reducing the variance of the delivery time distribution using a learning-based function. A limitation of Guiffrida & Nagi (2006) is the failure to include forgetting into the learning process. Given the discrete nature of the delivery process, learning can be lost during the time periods that accrue between deliveries. The first essay extends the research of Guiffrida & Nagi (2006) to include forgetting into the learning based approached for improving supply chain delivery performance. The literature on green and sustainable inventory management is quite limited and has mainly focused on the carbon footprint resulting with inventory management decisions (Bouchery et al. 2012). An examination of review papers on sustainable inventory models exposes the lack of integration of green and sustainable measures into stochastic inventory models. Of particular interest are stochastic inventory models with stockouts which examine the tradeoffs between backorders and lost sales. A limitation of these models is the failure to address environmental concerns in the stochastic inventory models with stockout decisions. The second essay integrates green and sustainable measures into stochastic inventory models which examine tradeoffs between backorders and lost sales. A review of stochastic cost-volume-profit (CVP) analysis models indicates that the inputs of the models as well as the resulting profit function are modeling using either the normal or the lognormal distribution. Using normal and lognormal distributions in stochastic CVP modeling represents a limitation to the general applicability of the models. In the third essay, we employ Mellin Transforms to expand and generalize the stochastic CVP model.
