Available in PDF, EPUB and Kindle. Book excerpt: In many biological models it is necessary to allow the rates of change of the variables to depend on the past history, rather than only the current values, of the variables. The models may require discrete lags, with the use of delay-differential equations, or distributed lags, with the use of integro-differential equations. In these lecture notes I discuss the reasons for including lags, especially distributed lags, in biological models. These reasons may be inherent in the system studied, or may be the result of simplifying assumptions made in the model used. I examine some of the techniques available for studying the solution of the equations. A large proportion of the material presented relates to a special method that can be applied to a particular class of distributed lags. This method uses an extended set of ordinary differential equations. I examine the local stability of equilibrium points, and the existence and frequency of periodic solutions. I discuss the qualitative effects of lags, and how these differ according to the choice of discrete or distributed lag. The models studied are drawn from the population dynamiCS of single species (logistic growth, the chemostat) and of interacting pairs of species (predation, mutualism), from cell population dynamiCS (haemopoiesis) and from biochemical kinetics (the Goodwin oscillator). The last chapter is devoted to a population model employing difference equations. All these models include non-linear terms.

Download or read book Collection Lags Fiscal Revenue and Inflationary Financing written by Mr.Nurun N. Choudhry and published by International Monetary Fund. This book was released on 1991-04-01 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper provides empirical evidence on collection lags in major categories of government revenue and analyzes the estimated revenue-eroding effects of inflation within the standard model of inflationary finance. The evidence indicates a wide variation in collection lags among the categories of revenues. The estimated erosion of real fiscal revenue, although varied in the sample countries, appears to have substantially offset gains from the inflation tax, thereby severely restricting the use of this form of taxation in generating resources.
Download or read book Collection Lags and the Optimal Inflation Tax written by Mr.Alex Mourmouras and published by International Monetary Fund. This book was released on 1993-07-01 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The observation that collection lags combine with inflation to erode fiscal revenues has long been a strong argument against seigniorage (Tanzi (1978)). However, with the exception of Dixit (1991), who used a general equilibrium model to reject this argument, the optimal tax literature has not analyzed how collection lags affect desired tax structures. In this paper, this issue is re-examined using an overlapping generations version of Dixit’s model. It is shown that depending on the specification of the collection cost function and the size of government spending in GDP, collection lags may increase, leave unchanged, or reduce the desired rate of inflation.

Download or read book Distributed Lags written by Phoebus J. Dhrymes and published by North Holland. This book was released on 1981 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents an analysis of the estimation of distributed lag models. It covers the algebraic structure of lag operators and examines the estimation of problems connected with finite and infinite lag structures, under a variety of assumptions pertaining to the error process. This revised edition emphasizes the potential applications of distributed lags, discussing the polynomial lag hypothesis and its relation to restricted least squares. Also, the test for autocorrelation of the error structure, when the model specification contains a lagged endogenous variable, is examined. The material is suitable for second-year graduate students in economics, and for undergraduates in statistics, mathematics, operations research, econometrics and electrical engineering, providing they have a background in calculus, linear algebra and mathematical statistics.

Book excerpt: The early settlers at the Swan River determined they would remain a free settlement, but after twenty years of unremitting struggle, as their economic circumstances became perilous, they were forced to petition the British Government for convicts and the much needed labour their presence would bring.Between 1850 and 1868, close to 10,000 male convict arrived in Western Australia from Britain. Far from being the detrimental influence many predicted, the 'lags', the detritus from the iniquities of the English legal and penal systems, injected new life into an stagnant economy. Despite a high percentage of original serious criminality among them, the vastly different environment in this most isolated of British settlements had a positive influence on these refugees from the cruel prisons and hulks of the Home country.The convict system in W.A. proved to be forward and benign by comparison with the systems of earlier decades in New South Wales and Tasmania. In consequence, many of the convicts who were landed at Fremantle subsequently became valuable citizens, helping to lay the foundations of early, modern Western Australia.
Download or read book Geostatistical Reservoir Modeling written by Michael J. Pyrcz and published by Oxford University Press. This book was released on 2014-04-16 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published in 2002, the first edition of Geostatistical Reservoir Modeling brought the practice of petroleum geostatistics into a coherent framework, focusing on tools, techniques, examples, and guidance. It emphasized the interaction between geophysicists, geologists, and engineers, and was received well by professionals, academics, and both graduate and undergraduate students. In this revised second edition, Deutsch collaborates with co-author Michael Pyrcz to provide an expanded (in coverage and format), full color illustrated, more comprehensive treatment of the subject with a full update on the latest tools, methods, practice, and research in the field of petroleum Geostatistics. Key geostatistical concepts such as integration of geologic data and concepts, scale considerations, and uncertainty models receive greater attention, and new comprehensive sections are provided on preliminary geological modeling concepts, data inventory, conceptual model, problem formulation, large scale modeling, multiple point-based simulation and event-based modeling. Geostatistical methods are extensively illustrated through enhanced schematics, work flows and examples with discussion on method capabilities and selection. For example, this expanded second edition includes extensive discussion on the process of moving from an inventory of data and concepts through conceptual model to problem formulation to solve practical reservoir problems. A greater number of examples are included, with a set of practical geostatistical studies developed to illustrate the steps from data analysis and cleaning to post-processing, and ranking. New methods, which have developed in the field since the publication of the first edition, are discussed, such as models for integration of diverse data sources, multiple point-based simulation, event-based simulation, spatial bootstrap and methods to summarize geostatistical realizations.
