Building on a base of simple economic theory and elementary linear algebra and calculus, this broad treatment of static and dynamic optimization methods discusses the importance of shadow prices, and reviews functions defined by solutions of optimization problems. Recently revised and expanded, the second edition will be a valuable resource for upper level undergraduate and graduate students.
From the Preface
The first edition of this book was written mainly for audiences with physical science and engineering backgrounds. Nevertheless, it reached some readers with economic and management science training. Analytical training of graduate students in economics and management sciences had progressed much in the last 20 years, and many new research results and optimization algorithms have also become available. My own interest in the meantime has shifted to the analysis of dynamics and optimization problems of economic and management science origin. With these developments and changes, I decided to rewrite much of the first edition to make it more accessible to graduate students and professionals in social sciences. I have also incorporated some new analytic tools that I deem useful in analyzing the dynamic and stochastic problems which confront these readers. I hope that my efforts successfully bring intertemporal optimization problems closer to economics professionals.
New topics introduced into this second edition appear mostly in Chapters 2, 4, 5, 6, and 8. Martingales and martingale differences are introduced early in Chapter 2. Some limit theorems and asymptotic properties of linear state space models driven by martingale differences are presented. Because many excellent books are available on martingales and their limit theorems, derivations and proofs are mostly sketchy, and readers are referred to these sources.
The results in Chapteer 2 are applied in Chapters 5, 6, and 8, among other places. The notion of dynamic aggregation and its relation to cointegration and error-correction models are developed in Chapter 4. Some recursive parameter estimation schemes and their statistical properties are included in Chapters 5 and 6. Here again, books devoted entirely to these topics are available in the literature, and much had to be omitted to keep the second edition to a manageable size. In an appendix to Chapter 7, a potentially very powerful tool in proving convergence of adaptive schemes is outlined. Rational expectations models and their solution methods are developed in Chapter 8 because of their wide-spread interest to economists. A very important class of problems in sequential decision problems revolves around questions of approximating nonlinear dynamics or more generally complex situations with a sequence of less complex ones. Chapter 9 does not begin to do justice to this class of problems but is included as being suggestive of works to be done.
When I first started contemplating the revision of the first edition, I benefited from a list of excellent suggestions from Rick van der Ploeg, though I did not necessarily incorporate all of his suggestions. Conversations with Thomas Sargent and Victor Solo were useful in organizing the material into the form of the second edition. I also benefited from discussions with Hashem Pesaran and correspondences with L. Broze in finalizing Chapter 8.
Some material in this book was used as lecture notes in a graduate course in the Department of Economics, University of California, Los Angeles, the winter quarter of 1987. I thank the participants in the course for many useful comments.

In this thesis we develop a new model called Medical Evacuation and Treatment Capabilities Optimization Model (METCOM) that’s designed as a user friendly optimization model that augments current simulations and assists in optimizing efficiencies, allowing for redistribution, restructuring, or realignment of medical resources and materials to better meet requirements elsewhere in the area of operations (AO). The model addresses variations in capabilities and policies of the medical evacuation and treatment system (METS) in order to discern effects on desired medical outcomes. A combination of descriptive and prescriptive multi-period models were utilized in order to identify policy effect on key measures of effectiveness (MOEs) and then fully optimize treatment and evacuation capacities for given casualty flows. Results provide medical planners and decision makers with coherent and relevant data allowing for the flexibility to employ a broad range of policies and capacities that would best meet the objectives of saving warfighters’ lives and minimizing resource capacity costs required while supporting the overall operational plan.

From the supplier: This paper develops and tests the implications of optimal consumption behavior with borrowing constraints. The theory shows that liquidity constraints imply a distinctive intertemporal relationship between durable and nondurable goods consumption. Binding liquidity constraints appear as part of an error correction term derived from the long-run cointegrating relationship between durables and nondurables. When liquidity constraints are binding, the error correction term will have predictive power for the future change in nondurable consumption. Empirical tests of the implications using aggregate data support the hypothesis that liquidity constraints, rather than rule-of-thumb behavior, best explain the excess sensitivity of consumption to predictable changes in income.

Over the past decade, retirement systems have undergone significant changes shifting from employersponsored pension plans to defined contribution plans, commonly referred to as 401(k) or individual retirement accounts (IRA). A critical aspect of these plans is that the individual, as opposed to the employer, is responsible for managing the account and its associated investments. Demographic data indicates that the proportion of the American population older than 55 is projected to increase considerably through 2050. In the very near future, millions of Americans will require sound advice regarding
myriad retirement financial decisions. Retirement strategies currently employed by financial planners are based on rules of thumb and have been
shown to be inefficient and poorly matched with retiree preference. This thesis demonstrates feasibility of applying inverse optimization and utility maximization as a means of developing efficient retirement portfolios based on
individual investment preferences. We administer a survey to collect investment preference data. Next, we implement a habit formation utility
model and develop a bi-level inverse optimization technique to quantify, estimate and parameterize retiree preference. Using our estimate, we generate preference-based optimal investment portfolios.
This book includes a collection of articles that present recent developments in the fields of optimization and dynamic game theory, economic dynamics, dynamic theory of the firm, and population dynamics and non standard applications of optimal control theory. The authors of the articles are well respected authorities in their fields and are known for their high quality research in the fields of optimization and economic dynamics.

Description:
An alternative approach to multi-region modeling will be presented. This approach (called modular approach) is able to reproduce results obtained with the traditional as well as a modified Negishi approach. We redesigned the Negishi approach to make it applicable in modeling technological spillovers induced by foreign direct investments. While the modular approach is able to completely internalize the external effects from technological spillovers, which result in higher welfare gains, the modified Negishi approach cannot completely internalize them. The latter is due to the fact that shadow prices from sectoral production functions are used in order to feed the process of iteratively adjusting the Negishi welfare weights. Under the modular approach, the way of finding an equilibrium solution in a dynamic and multi-regional framework is allocation-based and differs from existing price-oriented methods. We discuss the characteristics of the underlying adjustment algorithm which, in contrast to the joint maximization of the Negishi approach, is embedded in a decentralized optimization process. Results from numerical model experiments will demonstrate the advantage of this novel approach.

Description:
Our objective is to understand how risk aversion and elasticity of intertemporal substitution under recursive utility affect dynamic consumption-portfolio decisions. For a three-date model with a stochastic interest rate, we obtain an analytic solution for the optimal policies. We find that, in general, consumption and portfolio decisions depend on both risk aversion and elasticity of intertemporal substitution. The size of risk aversion relative to unity determines the sign of the intertemporal hedging portfolio, while elasticity of intertemporal substitution affects only its magnitude. The portfolio weight is independent of elasticity of intertemporal substitution only for the case of a constant investment opportunity set.
This monograph provides a concise introduction to the overlapping generations approach to the intertemporal economics of renewable natural resources. In contrast to the dominant infinitely-lived agent (ILA) approach it acknowledges that natural resources typically outlive the individuals who use them. Finite lifetimes, generations overlap and competing natural and man-made capital facilitate long-run intergenerational inefficiency and inequity (unsustainability) of market allocations. While avoiding any presumption of either doomsday or a golden age, the book investigates the structural and institutional preconditions needed to ensure that renewable resources are used efficiently and equitably across generations. The primary aim of this book is to provide an easy-to-follow guide to the analytically much more demanding journal literature. This is achieved by using the same model type throughout the book and by adhering to functional specifications that allow for explicit equilibrium solutions.
The book begins with an introduction to some of the basic concepts and results on chaotic dynamical systems. Next it turns to a detailed self-contained summary of the literature on discounted dynamic optimization. The first two chapters are of particular pedagogical interest. The volume also brings together a number of outstanding advanced research papers on complex behavior of dynamic economic models. These make it clear that complexity cannot be dismissed as "exceptional" or "pathological" and, for explanation and prediction of economic variables, it is imperative to develop models with special structures suggested by empirical studies. Graduate students in economics will find the book valuable for an introduction to optimization and chaos. Specialists will find new directions to explore themes like robustness of chaotic behavior and the role of discounting in generating cycles and complexity.
