This book explains complex scientific concepts using simple and understandable illustrations and practical examples. For example, the competition between countries in the world economy is compared to motor racing, time savings are illustrated through the example of a masquerade ball, and the cyclical effect of time on the economy is reflected through the prism of changing seasons. It presents amazing phenomena and processes of economic time, including 'economic vintage', 'the time machine in the economy', 'youth' and 'old age' of the economy, its 'growing up', 'the economic calendar', 'catching up', and 'forward-looking' development. This book will therefore be interesting not only to members of the scientific community but also to non-academic readers — to everyone who wants to understand the nature of economic time.

Control theory methods in economics have historically developed over three phases. The first involved basically the feedback control rules in a deterministic framework which were applied in macrodynamic models for analyzing stabilization policies. The second phase raised the issues of various types of inconsistencies in deterministic optimal control models due to changing information and other aspects of stochasticity. Rational expectations models have been extensively used in this plan to resolve some of the inconsistency problems. The third phase has recently focused on the various aspects of adaptive control. where stochasticity and information adaptivity are introduced in diverse ways e.g .• risk adjustment and risk sensitivity of optimal control, recursive updating rules via Kalman filtering and weighted recursive least squares and variable structure control methods in nonlinear framework. Problems of efficient econometric estimation of optimal control models have now acquired significant importance. This monograph provides an integrated view of control theory methods, synthesizing the three phases from feedback control to stochastic control and from stochastic control to adaptive control. Aspects of econometric estimation are strongly emphasized here, since these are very important in empirical applications in economics.

This is the third corrected and extended edition of a book on deterministic and stochastic Growth Theory and the computational methods needed to produce numerical solutions. Exogenous and endogenous growth, non-monetary and monetary models are thoroughly reviewed. Special attention is paid to the use of these models for fiscal and monetary policy analysis. Models under modern theories of the Business Cycle, New Keynesian Macroeconomics, and Dynamic Stochastic General Equilibrium models, can be all considered as special cases of economic growth models, and they can be analyzed by the theoretical and numerical procedures provided in the textbook. Analytical discussions are presented in full detail. The book is self-contained and it is designed so that the student advances in the theoretical and the computational issues in parallel. Spreadsheets are used to solve simple examples. Matlab files are provided on an accompanying website to illustrate theoretical results from all chapters as well as to simulate the effects of economic policy interventions. The logical structure of these program files is described in "Numerical exercise"-type of sections, where the output of these programs is also interpreted. The third edition corrects a few typographical errors, includes two new and original chapters on frequentist and Bayesian estimation, and improves some notation.

This volume is dedicated to Horst Todt who celebrated his seventieth an niversaryon March 14, 2000. All the contributors know Horst Todt personally and (with the exception of two younger co-authors) have accompanied his scientific career for sev eral years, some as his assistants, some as his colleagues at the Frankfurt or Hamburg University, some as fellow members in scientific societies. All who know him acknowledge inspiring conversations on a broad field of issues often reaching far beyond the scope of economics. Being friendly and entertaining and without exaggerated personal ambition he often initiated work which others completed. In particular the two editors of this volume experienced and enjoyed the stimulating atmosphere at his Chair of Economics at the Hamburg University. We like to remember these scientifically and personally fruitful years under the tutorship of Horst Todt. The editors would like to thank the contributors to this volume for their readiness to cooperate and for the promptness of their delivery.

This book focuses on the analysis of transportation economics development with spatiotemporal characteristics in both theory and practice. The comprehensive and general theory development, practical transportation events and policy implications are addressed. The book pursues three main objectives: firstly, to structurally describe the overall spatiotemporal transportation theory development; secondly, to break down transportation elements and transportation modes into railway, highway, water, civil aviation, pipeline and urban transportation for the purposes of in-depth professional analysis; and thirdly, to summarize transportation trends including car-hailing, shared bicycles, etc., in China to reveal their policy implications.

The Symposium aimed at analysing and solving the various problems of representation and analysis of decision making in economic systems starting from the level of the individual firm and ending up with the complexities of international policy coordination. The papers are grouped into subject areas such as game theory, control methods, international policy coordination and the applications of artificial intelligence and experts systems as a framework in economic modelling and control. The Symposium therefore provides a wide range of important information for those involved or interested in the planning of company and national economics.

This second volume covers all the conventional topics of international monetary theory and open-economy macroeconomics, and a lot more besides. Gandolfo treats such further concepts as the theory of monetary integration and the European monetary union, foreign exchange crises and the Tobin tax, theory of games and international policy coordination. It follows the "two-tier" structure of the first volume, and, thanks to its self-contained treatment, may equally be used as a reference book.
