Optimal Policy for Blood Inventory Management Problem
… is growing as well. In this work we find the optimal policy to use blood for transfusion for two blood types. The main goal is to find the policy that will reduce the shortage and minimize the risk of complications at the same time. For this purpose, we use two methods (Linear Programming and …

Three Essays on Search: Optimal Policy with Heterogeneous Workers
… is determined by free entry condition, optimal productivity investment decision, the participation constraint plus the steady state conditions. In this model I also show that heterogeneity is not the cause of multiplicity. The second chapter utilises the previous analysis to identify …

Optimal policy and the coexistence of markets and governments
… coexistence of governments and markets from an optimal policy point of view. In chapter 1, I study how the presence of financial markets shapes the government's ability to redistribute. Individuals do not, constrain consumption to equal their net-of- tax income every period, but instead use …

Disaster Risk Reduction in the Caribbean: Designing Optimal Policy Mixes
… have framed CC, interdisciplinary public policy scholars search for strategic policy designs to devise and implement a policy mix for sustainable development. This dissertation poses the question: How can better policy design enhance disaster risk reduction in the Caribbean? To examine …

Optimal government policy : a refutation of claims that optimal policy may be time inconsistent
… papers on the issue of the 'inconsistency' of optimal plans and the inferiority of 'consistent' solutions are then examined in chapters two and three. A synthesis of the literature is reviewed in chapter four. Chapter five stands by itself as an illustration of the logical difficulties …

Essays in Optimal Fiscal Policy
… three articles contribute to the literature on optimal fiscal policy with exogeneous government expenditures and distortionary taxation following Lucas and Stokey (1983) and Aiyagari et al. (2002) (AMSS). The first article extends the framework of AMSS by modelling agents ex ante heterogeneous …

Dynamic Pricing with Early Cancellation and Resale
… and derive the structural properties of the optimal policy and the optimal value function. For cases in which the customer's reservation price is exponentially distributed, we derive the optimal policy in a closed form. For general reservation price distribution, we consider an approximation …

Faster apprenticeship learning through inverse optimal control
… intelligence is learning how to behave optimally. With applications ranging from self-driving cars to medical devices, this task is vital to modern society. There are two complementary problems in this area – reinforcement learning and inverse reinforcement learning. While reinforcement …

A robust optimization approach to supply chains and revenue management
… that gives insight into the structure of the optimal policy and requires little knowledge of the underlying probability distributions. Instead, we build upon recent advances in the field of robust optimization to develop models of uncertainty that make few probabilistic assumptions and have an …

Optimal dynamic pricing for two perishable and substitutable products
… are exhausted. The seller's task is to post the optimal prices for the two product types to each customer to maximize the expected total revenue. We use dynamic programming to formulate this problem, and derive the optimal policy for special cases. For general cases, we develop an algorithm to …

Essays on the optimum quantity of money
… third essay introduces capital and derives the optimal rate of monetary policy in the presence of financial intermediaries. In the first essay a pure exchange model in which infinitely lived agents face stochastically varying endowments in each period is considered. In this model individuals can …

A constrained MDP-based vertical handoff decision algorithm for wireless networks
… when making the handoff decisions. The policy iteration and Q-learning algorithms are employed to determine the optimal policy. Structural results on the optimal vertical handoff policy are derived by using the concept of supermodularity. We show that the optimal policy is a threshold …

Essays in international economics
… holdings of financial assets for monetary policy and capital controls. I study an open economy model with nominal rigidities, incomplete markets, and assets denominated in home and foreign currency. I develop an approximation method that allows me to characterize the optimal policy sharply. …

Essays on sovereign debt and international capital flows
… international capital markets, with a focus on optimal policy for the government and international financial institutions. Chapter 1 focuses on sovereign debt and default. Recent sovereign default episodes have been associated with substantial output costs, and the sovereign should take into …

Actor-critic algorithms
… reward. In these formulations, finding an optimal decision policy involves computing a certain "value function" which assigns to each state the optimal reward one would obtain if the system was started from that state. This function then naturally prescribes the optimal policy, which is to …

Coordinating inventory control and pricing strategies
… model, and characterizing the structure of the optimal policy under various conditions. Specifically, for the finite horizon periodic review case, we show, by employing the classical k-convexity concept, that a simple policy, called (s, S, p), is optimal when the demand functions are additive. …

Cross-layer protocol interactions in heterogeneous data networks
… at the transport layer. Finally, we consider the optimal scheduling problem with window service constraints. Optimal policies that minimize the average response time of jobs are derived and the results show that both the job lengths and the window sizes are essential to the optimal policy.

Management of a high mix production system with interdependent demands : finished goods requirements and raw materials control
… frameworks are proposed: a fixed service level policy for the raw materials and an optimized policy for the finished goods. The optimal policy is validated using simulation. The proposed policies reduce the inventory value on hand for finished goods and raw materials by 35% and 30%, …

A deterministic multiechelon inventory model
… no stockouts allowed. General solutions for the optimal policy are obtained in the EOQ and finite production models. In the backorder model, the analytical argument is limited to the case in which only time dependent backorder costs occur. Algorithms are developed for solving problems for all …

Design of optimal investment policy for influence systems and online learning for job scheduling
… research thrusts, one related to the design of optimal investment policies for influence systems and the other related to online learning for job scheduling on heterogeneous machines. In Chapter 2, a continuous-time influence system on social networks is considered, where the goal is to decide …
