What This Book Actually Is
Economics Today by Roger Leroy Miller is an introductory microeconomics textbook. It has been around since the early 1980s and gone through multiple editions. The core content hasn't changed radically because the fundamentals of supply, demand, market structures, and consumer behavior don't change. What does change between editions are the case studies, the data tables, and occasionally some policy examples. The 13th edition (2014) is the last standalone microeconomics version. Later editions reorganized content into two separate volumes: the micro and macro perspectives. Most students encounter this textbook in a college-level principles course. It is designed to be accessible, with frequent real-world examples pulled from current events. The writing style is conversational rather than dense. That is a deliberate choice. Miller assumes readers have no prior economics background and builds from there. The book covers standard micro topics: scarcity and choice, supply and demand, elasticity, consumer theory, production and costs, perfect competition, monopoly, oligopoly, monopolistic competition, factor markets, market failures, and income distribution. Each chapter ends with review questions and problems. The math is kept light. There are graphs, but very few formal derivations or proofs. If you need a rigorous treatment of welfare economics, this is not the book for you.
I remember working with a student who struggled through the elasticity section because the textbook examples used percentage-change calculations that didn't match the homework platform's rounding rules. The discrepancy was small, maybe two to three cents on a calculated price, but the automated grading system marked it wrong every time. The fix was straightforward: we recalculated using the midpoint formula explicitly instead of the standard percentage formula, and entered values without rounding until the final step. That problem repeats across sections whenever an online homework system is involved. Another thing beginners miss is the distinction between a shift in demand and a movement along the demand curve. The textbook explains it, but the explanation is spread across two or three chapters. By the time you reach elasticity and government policies, the confusion compounds. I found that redrawing the same supply-demand diagram repeatedly with different scenarios on a blank whiteboard helped more than re-reading any single section. The visual consistency matters more than the wording. The book's strength is its case studies. Each chapter includes at least one current application, usually tied to something that happened in the news within the past few years. For example, the chapter on market structures has a discussion of airline pricing that still holds up, and the chapter on externalities references cap-and-trade programs that are relevant to actual policy debates. These sections are useful for writing papers or preparing for exams because they connect abstract models to concrete situations.
There are real limitations though. The treatment of game theory in oligopoly is superficial. You will learn the basic idea of a payoff matrix and dominant strategies, but nothing beyond that. If your course requires analysis of repeated games or Nash equilibrium refinement, you will need supplementary material. The same goes for behavioral economics. The textbook acknowledges it in a sidebar or two, but it does not integrate behavioral findings into the main model. For a course that wants that depth, you would be better off pairing this with Kahneman and Tversky readings or a more modern text. Pricing is another practical concern. A new hardcover copy runs around $200 to $250 depending on the retailer. The digital version is cheaper but still not trivial. Most students get it through their institution's library or purchase a used copy from a previous edition. The content difference between the 12th and 13th editions is minimal for the core concepts. If your professor is not specifically assigning questions from the newest edition's problem sets, a used 12th edition will save you significant money without costing you learning. One edge case I encountered involves the downloadable spreadsheet templates that sometimes accompany the textbook. They were included in earlier editions for calculation practice, but they became inconsistent across versions. The elasticity spreadsheet in the 13th edition had a hardcoded range reference that broke when students tried to apply it to data from a different chapter. The workaround was to manually recreate the formula structure rather than reuse the template. It took about ten minutes and eliminated the error.
Get the Full Details
If you are self-studying, the book works fine as a primary resource. Pair it with free online lectures if you need additional explanation. MIT OpenCourseWare and Khan Academy both cover the same material at no cost. The textbook gives you the structure and the practice problems. The lectures fill in the gaps when a particular explanation clicks better through audio and video than through print. For instructors considering adoption, the test bank and instructor resources are available through the publisher. They are adequate but not outstanding. The multiple-choice questions tend to be straightforward recall. If you want to assess deeper understanding, you will need to write your own questions or supplement with case-based assignments. The textbook alone will not get you there. The bottom line is that this is a solid entry-level textbook for microeconomics. It is not elegant. It is not exhaustive. It does what it says it will do: introduce the core tools of microeconomic analysis to students who have never seen them before. If that is your goal, it delivers. If you need more mathematical rigor, more behavioral depth, or a critical perspective on market outcomes, look elsewhere or supplement heavily.
