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.

We study the effect of ambiguity on timing decisions. An agent faces a stopping problem with an uncertain stopping payoff and a stochastic time limit. The agent is unsure about the correct model quantifying the uncertainty and seeks to maximize her payoff guarantee over a set of plausible models. As time passes and the agent updates, the worst-case model used to evaluate a given strategy can change, creating a problem of dynamic inconsistency. We characterize the stopping behavior in this environment and show that, while the agent's myopic incentives are fragile to small changes in the set of considered models, the best consistent plan from which no future self has incentives to deviate is robust.

Uncertainty is a fundamental characteristic of weather, seasonal climate, and hydrological prediction, and no forecast is complete without a description of its uncertainty. Effective communication of uncertainty helps people better understand the likelihood of a particular event and improves their ability to make decisions based on the forecast. Nonetheless, for decades, users of these forecasts have been conditioned to receive incomplete information about uncertainty. They have become used to single-valued (deterministic) forecasts (e.g., "the high temperature will be 70 degrees Farenheit 9 days from now") and applied their own experience in determining how much confidence to place in the forecast. Most forecast products from the public and private sectors, including those from the National Oceanographic and Atmospheric Administration's National Weather Service, continue this deterministic legacy. Fortunately, the National Weather Service and others in the prediction community have recognized the need to view uncertainty as a fundamental part of forecasts. By partnering with other segments of the community to understand user needs, generate relevant and rich informational products, and utilize effective communication vehicles, the National Weather Service can take a leading role in the transition to widespread, effective incorporation of uncertainty information into predictions. "Completing the Forecast" makes recommendations to the National Weather Service and the broader prediction community on how to make this transition.

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.

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.

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.

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.

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.
