Economics: Theory and Practice, 11th Edition (EHEP003392) cover image


Economics: Theory & Practice, 11th Edition by Patrick J. Welch and Gerry F. Welch connects theory to the practice of economics and the everyday world through examples and applications, debates, and critical thinking cases—some that are classics in the field and others that are fresh and up-to-date. Its balanced coverage of microeconomics and macroeconomics, flexibility in topic coverage order, and the use of appendices and chapter sections to shorten or deepen course material offer a choice of levels and sequences for a course.
