Armstrong, J. Scott ed., Principles of Forecasting, 2001. This summary of knowledge from experts and empirical studies provides guidelines that apply to economics, sociology, psychology and other fields. It addresses problems related to finance (How much is this company worth?), marketing (Will a new product be successful?), personnel (How can we identify the best job candidates?), and production (What level of inventories should be kept?). Edited by Professor J. Scott Armstrong of the Wharton School, University of Pennsylvania, this book contains contributions by 40 leading experts in forecasting. The 30 chapters cover all types of forecasting methods: judgmental methods, such as Delphi, role-playing, and intentions studies and quantitative methods, including econometric methods, expert systems, and extrapolation. Some methods, such as conjoint analysis, analogies, and rule-based forecasting, integrate quantitative and judgmental procedures. In each area, the authors identify what is known in the form of “if-then principles” and summarize evidence on these principles. The book also includes the first comprehensive forecasting dictionary.
Armstrong, J. Scott, Long-Range Forecasting: From Crystal Ball to Computer, John Wiley and Sons, 1985 (second edition). Designed to answer the question “Which forecasting method is the best to use in a given situation?” this book covers judgmental, extrapolation, and econometric methods. It shows how to combine forecasts and describes how to evaluate and compare different forecasting methods. The conclusions are based on the author’s research as well as on over 1050 books and papers on forecasting in economics, sociology, medicine, politics, weather, finance, personnel, marketing, and other areas. The book describes this vast array of literature. This second edition is out of print but is available online in a pdf of the full text.

Fildes, Robert, Ord, Keith, and Kourentzes, Nikolaos Principles of Business Forecasting, Wessex, 2017. This book serves both as a textbook for students and as a reference book for experienced forecasters in the many fields where forecasting is applied. The book introduces both standard and advanced forecasting methods and their underlying models, and also includes general principles to guide and simplify forecasting practice. The overall aim remains one of ensuring the techniques can be applied. A key strength of the book is its emphasis on real data sets, taken from government and business sources and used in each chapter’s examples and exercises. Forecasting techniques are demonstrated using a variety of software platforms and the companion website provides easy-to-use Excel® macros to support the basic methods.
Ferrara, Laurent, Hernando, Ignacio, Marconi, Daniela (eds.), International Macroeconomics in the Wake of the Global Financial Crisis, Springer, 2018. This book collects selected articles addressing several currently debated issues in the field of international macroeconomics. They focus on the role of the central banks in the debate on how to come to terms with the long-term decline in productivity growth, insufficient aggregate demand, high economic uncertainty and growing inequalities following the global financial crisis.
Gilliland, M., Tashman, L., and Sglavo, U. eds., Business Forecasting: Practical Problems and Solutions, Wiley, 2015. A compilation of some of the field’s important and influential literature into a single, comprehensive reference for forecast modeling and process improvement. Packed with provocative ideas from forecasting researchers and practitioners, on topics including accuracy metrics, benchmarking, modeling of problem data, and overcoming dysfunctional behaviors. Its coverage includes often-overlooked issues at the forefront of research, such as uncertainty, randomness, and forecastability, as well as emerging areas like data mining for forecasting. The articles present critical analysis of current practices and consideration of new ideas. With a mix of formal, rigorous pieces and brief introductory chapters, the book provides practitioners with a comprehensive examination of the current state of the business forecasting field.
Gilliland, Michael, The Business Forecasting Deal, Wiley, 2010. This book provides practical solutions to a wide variety of business forecasting problems. It illustrates how to think about business forecasting in the context of uncertainty, randomness, and process performance, all within the internal political arena in which real-life forecasting is conducted. Instead of focusing solely on statistical modeling and forecast accuracy (accuracy being largely determined by the nature of what is being forecast), this book focuses on forecasting process efficiency and effectiveness. It shows how to use Forecast Value Added (FVA) analysis to identify waste and inefficiency in a typical forecasting process, and how to eliminate the “worst practices” that sabotage an organization’s forecasting efforts.
González-Rivera, Gloria, Forecasting for Economics and Business, Prentice Hall, 2013. The general aim of this textbook is to develop sophisticated professionals able to critically analyze time series data and to produce sound forecasting reports. It provides a modern hands-on approach to the practice of forecasting. It covers forecasting (point forecasts and density forecasts) based on univariate and multivariate models for either stationary or non-stationary data, forecasting of volatility with interesting financial applications, and introductory material to forecasting with non-linear models. All chapters are motivated by real-life data, the same data sets that professional forecasters examine. Model simulations, visualization, and engagement with real data are classroom-tested features that facilitate learning.
Hyndman, R.J. and Athanasopoulos, G., Forecasting Principles and Practice, 3rd ed., OTexts, 2021. This textbook is intended to provide a comprehensive introduction to forecasting methods and present enough information about each method for readers to use them sensibly. We don’t attempt to give a thorough discussion of the theoretical details behind each method, although the references at the end of each chapter will fill in many of those details. The entire book is available online and free-of-charge.
Hyndman, R.J., Koehler A.B., Ord, J.K., Snyder, R.D., Forecasting with Exponential Smoothing: The State Space Approach, Springer-Verlag, 2008. Exponential smoothing methods have been around since the 1950s, and are still the most popular forecasting methods used in business and industry. Recently, exponential smoothing has been revolutionized with the introduction of a complete modeling framework incorporating innovations state space models, likelihood calculation, prediction intervals and procedures for model selection. In this book, all of the important results are brought together in a coherent manner with consistent notation. In addition, many new results and extensions are introduced and several application areas are examined in detail.
Kolassa, Stephan, Rostami-Tabar, Bahman, and Siemsen, Enno Demand Forecasting for Executives and Professionals, Routledge, 2024. This book surveys what executives who make decisions based on forecasts and professionals responsible for forecasts should know about forecasting. It discusses how individuals and firms should think about forecasting and guidelines for good practices. It introduces readers to the subject of time series, presents basic and advanced forecasting models, from exponential smoothing across ARIMA to modern Machine Learning methods, and examines human judgment’s role in interpreting numbers and identifying forecasting errors and how it should be integrated into organizations. There is also free (online) version.
