Modeling and Forecasting Primary Commodity Prices (Hardcover, New Ed): Walter C. Labys Modeling and Forecasting Primary Commodity Prices (Hardcover, New Ed)
Walter C. Labys
R4,598 Discovery Miles 45 980 Ships in 12 - 17 working days

Recent economic growth in China and other Asian countries has led to increased commodity demand which has caused price rises and accompanying price fluctuations not only for crude oil but also for the many other raw materials. Such trends mean that world commodity markets are once again under intense scrutiny. This book provides new insights into the modeling and forecasting of primary commodity prices by featuring comprehensive applications of the most recent methods of statistical time series analysis. The latter utilize econometric methods concerned with structural breaks, unobserved components, chaotic discovery, long memory, heteroskedasticity, wavelet estimation and fractional integration. Relevant tests employed include neural networks, correlation dimensions, Lyapunov exponents, fractional integration and rescaled range. The price forecasting involves structural time series trend plus cycle and cyclical trend models. Practical applications focus on the price behaviour of more than twenty international commodity markets.

Industrial Development and Environmental Degradation - A Source Book on the Origins of Global Pollution (Hardcover): Se H.... Industrial Development and Environmental Degradation - A Source Book on the Origins of Global Pollution (Hardcover)
Se H. Park, Walter C. Labys
R3,007 Discovery Miles 30 070 Ships in 12 - 17 working days

Industrialization to achieve economic development has resulted in global environmental degradation. While the impacts of industrial activity on the natural environment are a major concern in developed countries, much less is known about these impacts in developing countries. This source book identifies and quantifies the environmental consequences of industrial growth, and provides policy advice, including the use of clean technologies and environmentally sound production techniques, with special reference to the developing world.The developing world is often seen as having a high percentage of heavily polluting activities within its industrial sector. This, combined with a substantial agricultural sector, which contributes to deforestation, the erosion of the top soil and desertification, has lead to extreme pressures on the environment and impoverishes the population by destroying its natural resource base. This crisis suggests that sound industrialization policies are of paramount importance in a developing countries' economic development, and calls for the management of natural resources and the adoption of low-waste or environmentally clean technologies. The authors consider the industrial sector as a pollutant vis-a-vis other sectors of the economy, and then focus on some industry-specific pollutants within the manufacturing sector and some process-specific industrial pollutants. They conclude by reviewing the economic implications of promoting environmentally sound industrial development, specifically addressing the question of the conflict or complementarity which may exist between environmental goods and industrial production. The book will be essential to those working in industry, development and environmental economics.

International Commodity Market Models - Advances in Methodology and Applications (Paperback, Softcover reprint of the original... International Commodity Market Models - Advances in Methodology and Applications (Paperback, Softcover reprint of the original 1st ed. 1991)
O. Guvenen, Walter C. Labys, J.B. Lesourd
R2,976 Discovery Miles 29 760 Ships in 10 - 15 working days

RONALD C. DUNCAN During the 1980s, substantial advances were made in the global modelling of commodity markets in several areas, advances which were reflected in many of the papers delivered to the Applied Econometrics Association meeting held at the World Bank in Washington, DC, in October 1988. The several areas where I see advances being made, some of which the International Commodity Markets Division of the World Bank has taken part in, are the following: (a) in the theoretical specification of commodity price behaviour; (b) in the increased emphasis on modelling imperfect markets; (c) in the incorporation of the interrelationships between macro economic and commodity market variables; (d) in the specification of supply response, particularly in respect of perennial crops; and (e) in the realization of complementarity between time series analysis and economet rically estimated structural models. Improvements in the specification of the commodity price formation process have probably been the most important of the above advances. Until the early 1980s, prices were modelled as a simple linear function of stocks. Gilbert has played an important role in introducing the rational expecta tions hypothesis into the specification of commodity prices. Recent work by Gilbert, Trivedi, and Deaton and Laroque offers the possibility of non-linear specification of the relationship between prices and stocks within an expectational framework and of thereby capturing the phenomenon of sharp run-ups in commodity prices. Gilbert has also played an important role in clarifying the interrelation ships between macroeconomic variables and primary commodity prices."

Modeling Mineral and Energy Markets (Paperback, Softcover reprint of the original 1st ed. 1999): Walter C. Labys Modeling Mineral and Energy Markets (Paperback, Softcover reprint of the original 1st ed. 1999)
Walter C. Labys
R2,925 Discovery Miles 29 250 Ships in 10 - 15 working days

This book provides a framework for analyzing and forecasting a variety of mineral and energy markets and related industries. Such modeling activity has been at the forefront of the economic and engineering professions for some time, having received a major stimulus fC?llowing the first oil price shock in 1973. Since that time, other shocks have affected these markets and industries, causing disequilibrium economic adjustments which are difficult to analyze and to predict. Moreover, geopolitics remains an important factor which can destabilize crude oil markets and associated refining industries. Mineral and energy modeling, consequently, has become a major interest of energy-related corporations, mining and drilling companies, metal manufacturers, public utilities, investment banks,. national government agencies and international organizations. This book hopes to advance mineral and energy modeling as follows: (1) The modeling process is presented sequentially by leading the model builder from model specification, estimation, simulation, and validation to practical model applications, including explaining history, analyzing policy, and market and price forecasting; (2) New developments in modeling approaches are presented which encompass econometric market and industry models, spatial equilibrium and programming models, optimal resource depletion models, input-output models, economic sector models, and macro oriented energy interaction models (including computable general equilibrium); (3) The verification and application of the models is considered not only individually but also in relation to the performance of alternative modeling approaches; and (4) The modeling framework includes a perspective on new directions, so that the present model building advice will extend into the future.

Univariate Tests for Time Series Models (Paperback): Jeffrey B. Cromwell, Walter C. Labys, Michel Terraza Univariate Tests for Time Series Models (Paperback)
Jeffrey B. Cromwell, Walter C. Labys, Michel Terraza
R943 Discovery Miles 9 430 Ships in 12 - 17 working days

Taking a sequential approach to time-series model building, this book explores how to test for stationarity, normality, independence, linearity, model order, and properties of the residual process. The authors clearly define each testing procedure and offer examples to illustrate each concept. The authors also provide advice on how to perform the tests using different software packages. "This provides a nice roadmap for those doing time series analysis, and the authors should be applauded for this... Their approach is straightforward and logical and I believe will be useful many practicing statisticians." --Technometrics

International Commodity Market Modelling - Advances in Methodology and Applications (Hardcover, New): Walter C. Labys, Etc International Commodity Market Modelling - Advances in Methodology and Applications (Hardcover, New)
Walter C. Labys, Etc; Introduction by Lawrence R. Klein; Edited by Orhan Guyenen, Jean Baptiste Lesourd
R3,243 Discovery Miles 32 430 Ships in 10 - 15 working days

Part of a series, this volume comprises a selection of methodology-oriented papers presented at the 25th International Conference of the Applied Econometrics Association on International Commodity Market Modelling which took place at the World Bank, Washington, 1988. Economic and statistical analyses are obviously of great importance in studying commodity markets. A deep knowledge of market-clearing processes, the institutional structures of the industries related to each commodity market whether on the supply or demand side and the statistical methods of data handling for inference purposes are all needed in order to make good sense of the wealth of information on commodity market data. In addition, a technological understanding of the economic processes underlying each market is necessary. The agronomy of crop production, the techniques of crop distribution from harvest to end-use, the contributions of meteorology, the engineering of metallurgy, the engineering of processing factories, the combating of oil spills, the control of pollution and many other technological aspects of the different markets are essential for a good understanding of the forces at work in each case. Also legal and political factors play roles in the markets and require some specialized knowledge of their effects. Almost every market is different and so a specialized technological background is required, but that adds much substance to the research. By fitting together appropriate cross-disciplinary bodies of information in commodity market studies, a high degree of interest and analytical challenge can be attained.
