Book Description
Use of information is basic to economic theory in two ways. As a basis for optimization, it is central to all normative hypotheses used in eco nomics, but in decision-making situations it has stochastic and evolution ary aspects that are more dynamic and hence more fundamental. This book provides an illustrative survey of the use of information in econom ics and other decision sciences. Since this area is one of the most active fields of research in modern times, it is not possible to be definitive on all aspects of the issues involved. However questions that appear to be most important in this author's view are emphasized in many cases, without drawing any definite conclusions. It is hoped that these questions would provoke new interest for those beginning researchers in the field who are currently most active. Various classifications of information structures and their relevance for optimal decision-making in a stochastic environment are analyzed in some detail. Specifically the following areas are illustrated in its analytic aspects: 1. Stochastic optimization in linear economic models, 2. Stochastic models in dynamic economics with problems of time-inc- sistency, causality and estimation, 3. Optimal output-inventory decisions in stochastic markets, 4. Minimax policies in portfolio theory, 5. Methods of stochastic control and differential games, and 6. Adaptive information structures in decision models in economics and the theory of economic policy.

Book Description
Over the past several years there has been an awareness that mar kets, contractual arrangements, and hierarchical organizations can be uti lized as alternative modes of coordinating resource utilization in the con text of the firm. In most practical situations mixed forms of organization are more frequent. That is, non-market coordination mechanisms are being utilized even in predominantly market oriented economies. The reasons for the use of one of these organizational modes over the others are still being examined extensively. Very often, asset specificity and bilateral monopoly, risk sharing under uncertainty, transaction cost considerations, and/or technological externalities (economies of scope) have been considered as the major reasons for preferring one of these modes over the others. However, the ultimate effect on the performance of the firm, of any of these aspects which result in the adoption of any specific organizational pattern, has to be through the cost curve and/or the demand curve. The neoclassical welfare concepts, which have been developed to examine the efficiency in the functioning of markets, are well known. The sources of inefficiency in the performance of the firm under different mar ket structures are also well documented. However, there is as yet no well established set of concepts to examine the economic efficiency of the other organizational forms. It is not clear that the neoclassical welfare concepts are not relevant even under the new organizational setting. Studies of this nature are a relatively new area of economic research.

Book Description
Econometrics as an applied discipline attempts to use information in a most efficient manner, yet the information theory and entropy approach developed by Shannon and others has not played much of a role in applied econometrics. Econometrics of Information and Efficiency bridges the gap. Broadly viewed, information theory analyzes the uncertainty of a given set of data and its probabilistic characteristics. Whereas the economic theory of information emphasizes the value of information to agents in a market, the entropy theory stresses the various aspects of imprecision of data and their interactions with the subjective decision processes. The tools of information theory, such as the maximum entropy principle, mutual information and the minimum discrepancy are useful in several areas of statistical inference, e.g., Bayesian estimation, expected maximum likelihood principle, the fuzzy statistical regression. This volume analyzes the applications of these tools of information theory to the most commonly used models in econometrics. The outstanding features of Econometrics of Information and Efficiency are: A critical survey of the uses of information theory in economics and econometrics; An integration of applied information theory and economic efficiency analysis; The development of a new economic hypothesis relating information theory to economic growth models; New lines of research are emphasized.

Book Description
Although this book is primarily about economics, non-economic considerations, including political and ethical, are brought into the analysis. The most important decisions in life include choices between economic and non-economic issues. Hence, one of the aims of this book is to provide a conceptual framework to cope with these choices.

Book Description
In this book the authors explore the state of the art on efficiency measurement in health systems and international experts offer insights into the pitfalls and potential associated with various measurement techniques. The authors show that: - The core idea of efficiency is easy to understand in principle - maximizing valued outputs relative to inputs, but is often difficult to make operational in real-life situations - There have been numerous advances in data collection and availability, as well as innovative methodological approaches that give valuable insights into how efficiently health care is delivered - Our simple analytical framework can facilitate the development and interpretation of efficiency indicators.

Book Description
The problems arising from the existence of asymmetric information in public decision making have been widely explored by economists. Most of the traditional analysis of public sector activities has been reviewed to take accountofthe possible distortions arising from an asymmetric distribution of relevant information among the actors of the public decision-making process. A normative approach has been developed to design incentive schemes which tackle adverse selection and moral hazard problems within public organisations: our understanding of these problems is now much better, and some of the mechanisms designed have had important practical implications. While this analysis is still under way in many fields of public economics, as the papers by Jones and Zanola, and Trimarchi witness, a debate is ongoing on the possible theoretical limitations ofthis approach and on its actual relevance for public sector activities. This book encompasses different contributions to these issues, on both theoretical and practical areas, which were firstly presented at a conference in Catania. The innermost problem in the current discussion arises from the fact that this normative analysis is firmly rooted in the complete contracting framework, with the consequence that, despite the analytical complexities of most models, their results rely on very simplified assumptions. Most complexities of the organisation of public sector, and more generally, of writing "contracts", are therefore swept away.
