<p> Outbreaks of infectious diseases, such as influenza pandemics, can have significant impacts on interdependent economic sectors, and therefore lead to major economic losses. Based on findings from the 2009 A H1N1 influenza pandemic in the National Capital Region (NCR), this research work presents a risk analysis framework using Input-Output modeling. The present modeling enables to take into consideration the dynamic interdependencies between sectors in an economic system in addition to the inherent characteristics of the economic sectors. The risk of the influenza disaster is captured by two risk metrics. First, there is level of inoperability, which represents the percentage difference between the ideal output and the degraded output. Economic loss measures the dollar value of the degraded output. A primary contribution of this work revolves around the modeling of uncertainties regarding the occurrence of a new perturbation during the recovery of interdependent economic sectors and the resulting consequences due to influenza pandemic. The effect of the new perturbation depends on the nature of the disruption and the probability of its occurrence. The new disruption could lead to either the improvement or the deterioration of the economic sectors during their recovery horizon.</p><p> The level of inoperability of the economic sectors is assessed throughout their recovery horizon from the initial outbreak of the disaster until the after-disaster point of time using a dynamic model. Moreover, the inoperability level values are used to quantify the cumulative economic losses incurred by the sectors during the recovery period. Also, an uncertainty analysis approach is introduced to account for any new perturbation occurring during the recovery horizon of economic sectors. Such uncertainty would serve to assess the potential risk of occurrence of new perturbations and their associated ripple effects. Moreover, a decision-making framework is presented to capture the risk level for the economic sectors and their respective risk metrics. The decision support system is based on a large database of level of inoperability values and economic loss values generated through the simulations of different recovery periods and trajectories.</p>

<p>The strategic importance of corporate diversification on firm?s competitive advantage and superior financial performance has been extensively studied in the strategic management literature. However, in the field of operations management, there is a lack of research on whether and how corporate diversification strategies would impact a firm?s operational performance, and vice versa. To fill this research gap, in this dissertation, we conduct three empirical studies to investigate (1) how product and international diversification strategies influence a firm?s inventory performance; (2) how a firm?s existing resources and target market uncertainty jointly impact product scope expansion; and (3) how a firm?s utilization of resources impacts product scope expansion. The first essay aims to investigate the impacts of two important corporate diversification strategies on firm?s inventory performance: product diversification (including related and unrelated diversification) and international diversification. Based upon a large firm-level data sample collected from Compustat Fundamental Annual and Compustat Segment, we find that firm?s inventory level increases with the degree of related product diversification but decreases with the degree of unrelated product diversification. There is also strong evidence that highly internationally diversified firms tend to hold more inventory. Current research has investigated the importance of product scope to a firm?s operational performance (e.g., inventory efficiency, operational costs, and service levels). However, what drives a firm?s decision to expand its product scope remains under-studied. Recent real options research points to the role of uncertainty in the target market. The second essay adds to the literature by proposing that a firm?s resources endowments and target market uncertainty jointly influence its product scope. The empirical analysis confirms a curvilinear relationship between target market uncertainty and the likelihood of product scope expansion. More importantly, we find that different categories of resources alter the influence of target market uncertainty on product scope expansion differently. Given the fact that firms are striving for improving operational efficiency and reducing operational slack (i.e., resources in excess of what is required to fulfill expected demand), the third essay focuses on the effects of a firm?s capacity, inventory, and supply chain slacks on product scope decision. Our empirical results reveal that firms with more production and inventory slacks are more likely to expand product scopes. Furthermore, our analysis demonstrates that market relatedness positively moderates the effects of production and supply chain slacks on the likelihood of product scope expansion, but negatively moderates the effect of inventory slack on the likelihood of product scope expansion.
