Dynamic Timing Decisions Under Uncertainty


Book Description

Jay Forrester's Economic Dynamics was published in 1971 and The Limits to Growth by Dennis Meadows and his associates appeared a year later. The publication of those two books gave rise to twenty years of intense research into the economics of exhaustible resources, research which everywhere has had a substantial impact both on public debate and on academic curricula. And now, just as that line of research is losing steam, economists are focussing on problems associated with the degradation of the natural environment, problems which call for models which, in their formal structure, are quite similar to those already developed in resource economics. This is therefore an appropriate moment for the appearance of a thorough exposition of the economics of exhaustible resources. For that is what Nguyen Manh Hung and Nguyen Van Quyen have provided. Their splendid new book covers equally well the older Hotelling-inspired theory of cake-eating and the economics of search and R&D designed to uncover new and cheaper sources of supply. It provides an entree to the whole subject of resource economics, as well as many new discoveries which will be of interest to experienced researchers.




Decision Making under Deep Uncertainty


Book Description

This open access book focuses on both the theory and practice associated with the tools and approaches for decisionmaking in the face of deep uncertainty. It explores approaches and tools supporting the design of strategic plans under deep uncertainty, and their testing in the real world, including barriers and enablers for their use in practice. The book broadens traditional approaches and tools to include the analysis of actors and networks related to the problem at hand. It also shows how lessons learned in the application process can be used to improve the approaches and tools used in the design process. The book offers guidance in identifying and applying appropriate approaches and tools to design plans, as well as advice on implementing these plans in the real world. For decisionmakers and practitioners, the book includes realistic examples and practical guidelines that should help them understand what decisionmaking under deep uncertainty is and how it may be of assistance to them. Decision Making under Deep Uncertainty: From Theory to Practice is divided into four parts. Part I presents five approaches for designing strategic plans under deep uncertainty: Robust Decision Making, Dynamic Adaptive Planning, Dynamic Adaptive Policy Pathways, Info-Gap Decision Theory, and Engineering Options Analysis. Each approach is worked out in terms of its theoretical foundations, methodological steps to follow when using the approach, latest methodological insights, and challenges for improvement. In Part II, applications of each of these approaches are presented. Based on recent case studies, the practical implications of applying each approach are discussed in depth. Part III focuses on using the approaches and tools in real-world contexts, based on insights from real-world cases. Part IV contains conclusions and a synthesis of the lessons that can be drawn for designing, applying, and implementing strategic plans under deep uncertainty, as well as recommendations for future work. The publication of this book has been funded by the Radboud University, the RAND Corporation, Delft University of Technology, and Deltares.




Technical Progress and Economic Growth


Book Description

In this book we intend to discuss economic fluctuations and growth and possible stabilizing fiscal policies. Since these topics are major preoccupa tions of economic theorists and have been extensively discussed since the classics, one may wonder why another book on these subjects. A possible defense is that we are going to do so in the framework of a two-sector model where the main featureS of each sector depend on the characteristics of the goods produced by the sector itself. The conventional wisdom suggests that the problem of (dis )aggregation in growth and business cycle theory is basically a quantitative one: the model should consider as many sectors, goods, and agents as necessary to provide a sufficiently rich picture, the upper bound obviously resulting from the tractability of the problem. In this attitude the same equilibrium (or diseqUilibrium) assumptions generally hold true throughout all sectors. Here we want to prove the relevance of an alternative approach: we look at the qualitative differences across sectors and at the peculiarities of each market as at the determinants of the economic dynamics. This tradition goes back over one hundred years to Tugan-Baranowkj and has been de veloped by Aftalion, Fanno, Spiethof, and Lowe, but has never been sys tematically formalized.




A Macroeconomic Model of West German Unemployment


Book Description

The book offers an explanation of unemployment based on a model of wage bargaining between a trade union and an employers' association. The theoretical model emphasizes the importance of distributional fairness in wage negotiations, especially with regard to factor taxation. This is achieved by the application of the proportional solution to the bargaining problem. It is shown, that this solution concept delivers a reasonable model of long run wage determination in which the natural rate of unemployment is independent of productivity growth. Taxes on labour and capital are identified as important determinants of equilibrium employment, the labour tax having a negative, the capital income tax having a positive effect. The latter result distinguishes the model from the standard literature. An empirical test using cointegration methods with West German data confirms the theoretical predictions.




Design of Master Agreements for OTC Derivatives


Book Description

I first came across the issue of derivatives documentation when writing my diploma thesis on measuring the credit risk ofOTC derivatives while I was an economics student at the University of Bonn. Despite the fact that security design has been an area of research in economics for many years and despite the widespread use of derivatives documentation in financial practice, the task of designing contracts for derivatives transactions has not been dealt with in financial theory. The one thing that aroused my curiosity was that two parties with usually opposing interests, namely banking supervisors and the banking industry's lobby, unanimously endorse the use ofcertain provisions in standardized contracts called master agreements. Do these provisions increase the ex ante efficiency of contracts for all parties involved? I actually began my research expecting to find support for the widely held beliefs about the efficiency or inefficiency of certain provisions and was sur prised to obtain results that contradicted the conventional wisdom. I would strongly advise against using these results in any political debate on deriva tives documentation. They were obtained within a highly stylized model with some restrictive assumptions. This work should rather be seen as an attempt to formalize the discussion on derivatives documentation and to challenge the notion that certain provisions are generally ex ante efficient. It is also an invitation to all those advocating the use of certain provisions in master agreements to formalize their arguments and to explain the economic ratio nale behind these provisions.




Litigation and Settlement in a Game with Incomplete Information


Book Description

We investigate a two-person game of litigation and settlement with incomplete information on one side. So far, various theoretical attempts have been made to answer the question of why some people choose not to resolve their disputes and instead go to court and incur litigation costs, even if bargaining leaves room for both parties to fare better when avoiding the conflict. We can distinguish between games which focus on strategic elements like games with incomplete information (see, for example, P'ng (1983), Samuelson (1982) and Schweizer (1989» and decision-theoretic models neglecting strategic elements (see, for example, Landes (1971) and Gould (1973». The single-person decision theory approach to litigation assumes litigants to have a subjective estimate of the likelihood that the plaintiff will win the action. Differing views on the probability of winning the court case help to explain the fraction of cases that actually go to trial. Among others, P'ng (1983) points out the shortcomings of the single-person decision theory approach which does not take into account, for example, the different fee systems in England and the U.S. and the differences in information conflicting parties may have. P'ng constructs a model of one-sided incomplete information where the settlement terms are given exogenously. Schweizer (1989), on the other hand, extends P'ng's model and allows for two-sided asymmetric information where the settlement terms are determined endogenously.




On Overlapping Generations Models with Productive Capital


Book Description

This book was born out of a five-years research at Sonderforschungsbe reich 303 by the Deutsche Forschungsgemeinschaft (DFG) at Rheinische Friedrich-Wilhelms-Universitiit Bonn and was approved as my doctoral thesis by the Rechts-und Staatswissenschaftliche Fakultiit in December 1994. It was my former colleague Wolfgang Peters who had drawn my atten tion to overlapping-generations models and to problems of intergenerational efficiency and distribution. The subtle connection between the latter two has been fascinating me from the very beginning: redistribution of the results of free trade can become necessary from the point of view of efficiency, although no externalities hamper the development of an economy. In spite of being a matured part of economics, neoclassical growth theory had left many questions unsolved, some of them even unrecognized by a large part of our profession. I took up the challenge to contribute to the investigation of some of these thorny problems. One of these issues is the often quoted idea of the inter generational con tract. Although intergenerational transfers can improve intertemporal effi ciency, the design of pension schemes to achieve an improvement of well-being of some generations without hurting that of any other, is not an easy task in an economy with flexible prices. Quite frequently, only interest rate and growth rate are taken into account when deciding on whether a generation wins or looses.




General Equilibrium with Increasing Returns


Book Description

This is a book on general equilibrium in which firms are allowed to exhibit increasing returns to scale (more precisely, in which the convexity of production sets is not assumed). As such, it provides a full fledged general equilibrium model and analyzes the chief questions concerning existence and optimality. Increasing returns is a topic which many economists find it to be simultaneously very imponant, very difficult and very discouraging. It is very important because it refers to a well established technological phenomenon which is essentially incompatible with the functioning of competitive markets. It is very difficult because the standard concepts and tools for the analysis fail (in particular, the supply mappings are not well defined). It is very discouraging because the available models do not seem to solve the basic questions: Normative models where nonconvex firms follow marginal pricing do not achieve efficient outcomes, and positive models cannot incorporate monopolistic competition as a way of defming the behavior of those firms with increasing returns to scale. I would like to think that this monograph will contribute to show that "the increasing returns question" is neither too difficult nor too discouraging. Concerning the difficulty, it will be shown that the analysis can be carried out with essentially the same tools as those applicable to the standard competitive model. As for the relevance of the results available, let me point out the following.




Transitional Dynamics and Economic Growth in Developing Countries


Book Description

Four stylised facts of aggregate economic growth are set up initially. The growth process is interpreted to represent transitional dynamics rather than balanced-growth equilibria. Against this background, the fundamental importance of subsistence consumption is comprehensively analysed. Subsequently, the meaning of the productive-consumption hypothesis for the intertemporal consumption trade-off and the growth process is investigated. Finally, the process of growth is analysed empirically by means of cross-sectional conditional convergence regressions with endogenous control variables.




Bargaining in Economic and Ethical Environments


Book Description

Two features are combined in this book: the analysis of bargaining experiments and the development of axiomatic bargaining theories. Further, a new type of the latter is derived from observations in the former. The author describes bargaining experiments with different economic and ethical frames as well as developing axiomatic approaches to characterize the corresponding bargaining solutions.
