The Sum of the Satisfactions


Book Description

In our age of measurement, economic numbers - productivity, inflation, unemployment, gross domestic product - inform the decisions of both citizen and state. Since World War II, Canada has been at the global forefront in developing a set of national accounts that measure every beat of our economic pulse. The story of our national accounts - today administered by Statistics Canada - involves courage, personal tragedy, and a Canadian knack for innovation.










Sum of Squares: Theory and Applications


Book Description

This volume is based on lectures delivered at the 2019 AMS Short Course “Sum of Squares: Theory and Applications”, held January 14–15, 2019, in Baltimore, Maryland. This book provides a concise state-of-the-art overview of the theory and applications of polynomials that are sums of squares. This is an exciting and timely topic, with rich connections to many areas of mathematics, including polynomial and semidefinite optimization, real and convex algebraic geometry, and theoretical computer science. The six chapters introduce and survey recent developments in this area; specific topics include the algebraic and geometric aspects of sums of squares and spectrahedra, lifted representations of convex sets, and the algorithmic and computational implications of viewing sums of squares as a meta algorithm. The book also showcases practical applications of the techniques across a variety of areas, including control theory, statistics, finance and machine learning.










Essentials of Business Research Methods


Book Description

In an era of big data and data analytics, how can managers make decisions based on almost unlimited information, not to mention hiring and retaining individuals with the required data analytics skills? The new fourth edition of Essentials of Business Research Methods explains research methods and analytical techniques for individuals who aren't data scientists. The authors offer a straightforward, hands-on approach to the vital managerial process of gathering and using data to make relevant and timely business decisions. They include critical topics, such as the increasing role of online research, ethical issues, privacy matters, data analytics, customer relationship management, how to conduct information-gathering activities more effectively in a rapidly changing business environment, and more. This is also the only text that includes a chapter on qualitative data analysis, and the coverage of quantitative data analysis is more extensive as well as much easier to understand than in other texts. A realistic continuing case used throughout the book, applied research examples, and ethical dilemma mini cases enable upper-level undergraduate and postgraduate students to see how business research information is used in the real world. This comprehensive textbook is supported by a range of online resources, including instructors’ manuals, PowerPoint slides, and test banks.







A Brief History of Price


Book Description

This book is an attempt to explain to the layperson what contemporary economics is about. It starts on the assumption that most economics is just refined common sense and clearly explains the key ideas associated with each issue. All the main topics of academic economics are considered: the theory of individual choice, the labour market, the competition between firms, international trade, economic growth, the stock market, unemployment, and money. The general principles are sketched first without maths or diagrams, and then discussed in the context of topical problems such as the collapse of communism in Eastern Europe, the lack of development in the third-world countries, the contrast between market forces and the protection of the environment, showing how economics is not necessarily a dry academic pursuit.
