Book excerpt: El objetivo de este proyecto es describir una metodología de previsión de ventas que permita establecer un modelo de previsión adecuado dada una casuística concreta. Por ello, se realizan diversos análisis con el fin de conocer el impacto de las previsiones de ventas y qué técnicas de previsión son las más adecuadas para cada caso particular. La metodología descrita y los resultados de los análisis son aplicados a un caso práctico en el que se desea predecir las ventas de un establecimiento minorista de la compañía Walmart. La metodología de previsión de ventas presentada considera diversos métodos de previsión. Con el fin de conocer qué métodos son los más adecuados para cada casuística, es importante conocer y entender el impacto de las previsiones de venta en la gestión de la cadena de suministro. Por ello, se analiza, considerando diferentes tipologías de producto, el impacto que las previsiones generan en los niveles de existencias y en la gestión de las actividades de todos los actores que forman la cadena de abastecimiento. Con el fin de mejorar la eficiencia de la cadena de suministro, se concluye que es importante predecir con una precisión elevada y en todas las etapas de la cadena, las ventas de productos que generan un gran número de ventas y/o ingresos, que tienen un elevado coste de stock, un alto riesgo a generar stock obsoleto o un tiempo de abastecimiento alto. Con el fin de conocer que métodos de previsión deben ser considerados al aplicar la metodología descrita en un caso particular, se realiza un análisis de los diversos métodos y técnicas de previsión de ventas existentes. De este análisis se destaca que las ventas pueden ser previstas mediante métodos cualitativos o mediante métodos cuantitativos. Los segundos son en general más precisos y deben ser considerados cuando se dispone de un histórico de datos. Los métodos cuantitativos se dividen en métodos estadísticos basados en el análisis de series de tiempo y en métodos causales. Tradicionalmente las ventas son previstas utilizando modelos de series temporales; entre los que destacan las variaciones de los modelos autorregresivos integrados de medias móviles (ARIMA) y de los modelos de alisado exponencial. A pesar de ello, en el presente trabajo, se analizan también métodos causales de aprendizaje automático los cuales permiten, en general, la obtención de resultados más precisos. En la resolución del caso práctico, donde se aplica la metodología presentada y se analiza la precisión de las previsiones aplicando diferentes modelos de previsión, se define un modelo de aprendizaje automático para realizar las previsiones de venta del establecimiento Walmart considerado. El modelo propuesto se basa en el aprendizaje combinado y considera las previsiones de un modelo de bosques aleatorios, en un 70%, y las de un modelo de regresión lineal, en un 30%; y, presenta una precisión del 96, 57 %. En el caso práctico, se valora también el impacto de aplicar el modelo de ventas propuesto en el establecimiento Walmart.

Book excerpt: This book addresses two significant research areas in an interdependent fashion. It is first of all a comprehensive but concise text that covers the recently developed and widely applicable methods of qualitative choice analysis, illustrating the general theory through simulation models of automobile demand and use. It is also a detailed study of automobile demand and use, presenting forecasts based on these powerful new techniques. The book develops the general principles that underlie qualitative choice models that are now being applied in numerous fields in addition to transportation, such as housing, labor, energy, communications, and criminology. The general form, derivation, and estimation of qualitative choice models are explained, and the major models - logit, probit, and GEV - are discussed in detail. And continuous/discrete models are introduced. In these, qualitative choice methods and standard regression techniques are combined to analyze situations that neither alone can accurately forecast. Summarizing previous research on auto demand, the book shows how qualitative choice methods can be used by applying them to specific auto-related decisions as the aggregate of individuals' choices. The simulation model that is constructed is a significant improvement over older models, and should prove more useful to agencies and organizations requiring accurate forecasting of auto demand and use for planning and policy development. The book concludes with an actual case study based on a model designed for the investigations of the California Energy Commission. Kenneth Train is Visiting Associate Professor in Economics at the University of California, Berkeley, and Director of Economic Research at Cambridge Systematics, Inc., also in Berkeley. Qualitative Choice Analysisis included in The MIT Press Transportation Studies Series, edited by Marvin L. Manheim.

Book excerpt: Optimal Regulation addresses the central issue of regulatory economics - how toregulate firms in a way that induces them to produce and price "optimally." It synthesizes the majorfindings of an extensive theoretical literature on what constitutes optimality in various situationsand which regulatory mechanisms can be used to achieve it. It is the first text to provide aunified, modern, and nontechnical treatment of the field.The book includes models for regulatingoptimal output, tariffs, and surplus subsidy schemes, and presents all of the material graphically,with clear explanations of often highly technical topics.Kenneth E. Train is Associate AdjunctProfessor in the Department of Economics and Graduate School of Public Policy at the University ofCalifornia, Berkeley. He is also Principal of the firm Cambridge Systematics.Topics include: Thecost structure of natural monopoly (economies of scale and scope). Characterization of firstandsecond-best optimality. Surplus subsidy schemes for attaining first-best optimality. Ramsey pricesand the Vogelsang-Finsinger mechanism for attaining them. Time-ofuse (TOU) prices and Riordan'smechanisms for attaining the optimal TOU prices' Multipart and self-selecting tariffs, and Sibley'smethod for using self-selecting tariffs to achieve optimality. The Averch-Johnson model of howrate-of-return regulation induces inefficiencies. Analysis of regulation based on the firm's returnon Output, costs, or sales. Price-cap regulation. Regulatory treatment of uncertainty and its impacton the firm's behavior. Methods of attaining optimality without direct regulation (contestability,auctioning the monopoly franchise.)

Available in PDF, EPUB and Kindle. Book excerpt: This edition of the World Bank has been revised and expanded by the Terminology Unit in the Languages Services Division of the World Bank in collaboration with the English, Spanish, and French Translation Sections. The Glossary is intended to assist the Bank's translators and interpreters, other Bank staff using French and Spanish in their work, and free-lance translator's and interpreters employed by the Bank. For this reason, the Glossary contains not only financial and economic terminology and terms relating to the Bank's procedures and practices, but also terms that frequently occur in Bank documents, and others for which the Bank has a preferred equivalent. Although many of these terms, relating to such fields as agriculture, education, energy, housing, law, technology, and transportation, could be found in other sources, they have been assembled here for ease of reference. A list of acronyms occurring frequently in Bank texts (the terms to which they refer being found in the Glossary) and a list of international, regional, and national organizations will be found at the end of the Glossary.

Available in PDF, EPUB and Kindle. Book excerpt: A manifesto for a radically different philosophy and practice of manufacture and environmentalism "Reduce, reuse, recycle" urge environmentalists; in other words, do more with less in order to minimize damage. But as this provocative, visionary book argues, this approach perpetuates a one-way, "cradle to grave" manufacturing model that dates to the Industrial Revolution and casts off as much as 90 percent of the materials it uses as waste, much of it toxic. Why not challenge the notion that human industry must inevitably damage the natural world? In fact, why not take nature itself as our model? A tree produces thousands of blossoms in order to create another tree, yet we do not consider its abundance wasteful but safe, beautiful, and highly effective; hence, "waste equals food" is the first principle the book sets forth. Products might be designed so that, after their useful life, they provide nourishment for something new-either as "biological nutrients" that safely re-enter the environment or as "technical nutrients" that circulate within closed-loop industrial cycles, without being "downcycled" into low-grade uses (as most "recyclables" now are). Elaborating their principles from experience (re)designing everything from carpeting to corporate campuses, William McDonough and Michael Braungart make an exciting and viable case for change.

First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive introduction to the concepts, theories, and applications of pricing and revenue optimization. From the initial success of "yield management" in the commercial airline industry down to more recent successes of markdown management and dynamic pricing, the application of mathematical analysis to optimize pricing has become increasingly important across many different industries. But, since pricing and revenue optimization has involved the use of sophisticated mathematical techniques, the topic has remained largely inaccessible to students and the typical manager. With methods proven in the MBA courses taught by the author at Columbia and Stanford Business Schools, this book presents the basic concepts of pricing and revenue optimization in a form accessible to MBA students, MS students, and advanced undergraduates. In addition, managers will find the practical approach to the issue of pricing and revenue optimization invaluable. Solutions to the end-of-chapter exercises are available to instructors who are using this book in their courses. For access to the solutions manual, please contact [email protected].

Available in PDF, EPUB and Kindle. Book excerpt: Based on twenty case studies of universities worldwide, and on a survey administered to leaders in 101 universities, this open access book shows that, amidst the significant challenges caused by the COVID-19 pandemic, universities found ways to engage with schools to support them in sustaining educational opportunity. In doing so, they generated considerable innovation, which reinforced the integration of the research and outreach functions of the university. The evidence suggests that universities are indeed open systems, in interaction with their environment, able to discover changes that can influence them and to change in response to those changes. They are also able, in the success of their efforts to mitigate the educational impact of the pandemic, to create better futures, as the result of the innovations they can generate. This challenges the view of universities as "ivory towers" being isolated from the surrounding environment and detached from local problems. As they reached out to schools, universities not only generated clear and valuable innovations to sustain educational opportunity and to improve it, this process also contributed to transform internal university processes in ways that enhanced their own ability to deliver on the third mission of outreach
