A timely guide that bridges the gap between microeconomic theory and practice through real-world application in the marketplace

Understanding how microeconomics affects the marketplace is essential for any investment professional, however most books simply address microeconomics in its pure theory-based form. Micro Markets helps bridge the gap between theory and practice by defining microeconomics in terms of real-world, market applications.

This timely guide elucidates basic microeconomic concepts with an emphasis on applicability. It establishes a common application for all of the basic economic concepts that are reviewed, and provides in-depth insights into an industry that is of major economic importance in aggregate, and to most individuals.

  • Utilizes equity market realities to underscore the relevance of economic theory
  • Each chapter includes informative practice problems and power points
  • A companion Workbook, with practice problems and solutions, is also available

By taking microeconomic theory and making it applicable to today's marketplace, Micro Markets builds a much-needed bridge between theory and practice.
