Course is open to incoming SAIS MAIR and MAIA students only. Admitted students who have not completed the economics admissions requirement will be auto-enrolled in the course. (Admitted MA in Sustainable Energy students should enroll in the Economics Basics course offered through their program.)

Students must receive a B- or higher in Principles of Economics in order to meet the requirements for the MAIR and MAIA degree programs. This is a prerequisite for International Economics I and International Economics II (or Essentials).

The scope of the book is impressive, it even includes a chapter on the recent history of macroeconomic thought, with a great discussion of the macroeconomic policy during Great Depression, and since, doing a good job integrating the tools developed in earlier chapters. I don't recall seeing anything close to this in other intro to economics textbooks that I have seen. Individual topics are developed in sufficient depth, for instance the discussion of marginal benefit and marginal cost in chapter 6 is more detailed than in most of the other textbooks that I have seen. While the scope of the coverage is great, I couldn't find an index or a glossary of terms. Important terms are highlighted in the text, but I couldn't find a list of definitions to these.

The textbook seems to be accurate, without errors, and I think the author does a good job providing a balanced view, at least judging by the standards set by other principles of economics textbooks. The inclusion of topics is very standard and the discussion seems objective. I would personally like to see inclusion of the Austrian View of the Business Cycle, and of a more critical perspective on inflation, debt, and the role of government in general.

The lack of recent updates is in my opinion the main weakness of the textbook. In most chapters it doesn't matter much, but for the discussion of monetary and fiscal policy it is important to point out that the discussion in the textbook ends with the immediate aftermath of the 2008 recession, thus is missing the more recent changes in the Fed's policy and recent developments. The book lacks a discussion of negative interest rates, Fed's growing balance sheet, and the recent increases in government debt and budget deficits. This seems not to have been updated since 2010.

For an economics textbook, the writing is easy to understand, which makes it accessible to a wide range of students, but may not be an ideal choice for a more advanced student who may prefer a more demanding text. I found many of the examples interesting and engaging, for instance the example of smokers being on net a positive externality in chapter 11, or the example of hockey teams maximizing profits in chapter 10.

Each chapter is organized in a few sections, each with its own learning objectives, examples, and a few questions to be answered. It seems easy to either pick a section from a chapter, or skip a section, without losing continuity. It seems effort was put into chapters being able to stand alone on their own, for instance there is a separate chapter (23) on economic growth, investment (29), and interest rate - loanable funds market (13).

As mentioned under Modularity, the book does a good job including many stand-alone chapters, but this creates a problem in organization. For instance it is difficult to make the connection among interest rates, investment, saving, consumption, and economic growth, as the coverage is spread across chapters 13, 23, and 29. There is a small sub-section (a little over a page) in section 29.1 explaining the relationships, but overall I had difficulties finding the main points among the detailed discussion. I could see students getting a bit lost in the detail presented, and not being able to clearly see the bigger picture.

This is a great textbook, likely to please anyone looking for a standard introductory economics text done well and freely available. The only significant downside is that it hasn't been updated since about 2010, which I find problematic for the monetary and fiscal policy discussions.

This book includes all the usual principles topics, and then some. Want to talk about the effect of third-party payers in health care markets? Farm policy? Economies in transition? There's a chapter for each of these topics. Throughout, there are references to important historical events, which I appreciate. The Great Depression, for example, is mentioned several times. Some depth is sacrificed, through, to hit on all of these topics. I did not see a glossary, which is a glaring omission for an introductory textbook. In-text problems, with solutions, and end-of-chapter problems are included.

I did not notice any inaccuracies. Perhaps this is more of an interface issue, but I did notice a problem with the formula for elasticity. At least in the online version I was reading from, equation 5.1 "did not parse." This could be a big issue for students trying to understand the elasticity chapter. However, students would also probably be better than I am at finding a format that works

This text does a nice job of including a lot of environmental examples, which I think students usually find interesting and relevant. Chapter 1, for example, refers to oil extraction and water use, as well as careers and salaries in economics (another topic that should be of interest). Most case-in-point articles are at least 10 years old, though. I would like to see these updated.

In addition to the lack of depth, I find the writing style a little choppy. Reading this text is a little like reading a small-town newspaper. I frequently wanted more investigative reporting instead of just-the-facts. I am currently using the Krugman and Wells text (for Micro Principles), largely because it reads in many parts like a story.

I did not find many spots where I felt students would be confused, other than one spot in chapter 1, where a good is defined as "scarce" if it has alternative uses, such as air which we can either breathe or pollute. In other words, a good is scarce if it is limited. In contrast, a free good is not limited, like gravity. I find these examples (air and gravity, illustrating opposites) a little confusing particularly for chapter 1. If I were the author, I would avoid mention of free goods to emphasize that virtually everything is scarce. This is a minor issue, but I hate to see any issues so early in the book that might discourage later reading. In contrast, the section in this chapter on careers in economics is clear and engaging.

Generally speaking, the text follows the usual order, micro then macro. Personally, I would have rearranged the chapters a little. For example, I would probably use chapter 6 (consumer surplus, and deadweight loss) before chapter 4 (applications of supply and demand) so we can analyze deadweight loss from price controls. Also, the Keynesian Cross from chapter 28 goes before Aggregate Demand and Supply (chapter 22). But you can always cover in any order you want.

The flow suffers a little from the choppy writing style and lack of depth I mentioned under Clarity. Perhaps students appreciate this more than I do, however.

This is a real strength of the text. New terms are highlighted in blue. The graphs and charts are colorful and easy-to-read. I only found a few issues from the online version that I read from. First the elasticity formula didn't come through, and one of the TryIt! problems in chapter 2 appears to be missing part of the table. There is reference to the production possibilities for Plant R and Plant S, and I only see a table for Plant R.

I like that instructors can easily pick and choose chapters, and the graphs and charts are colorful and engaging. Each chapter has TryIt! problems with answers, as well as end-of-chapter problems (both conceptual problems and numerical problems). The case-in-point articles are relevant but a bit dated. Will they be updated? Also, I just find it strange that the authors are "unnamed" or "anonymous." Is this common with OER textbooks? I just feel obligated to give credit where credit is due--I'm not sure I can put anonymous on my syllabus.

Comprehensive in overall coverage; yet many on the sections leave out important discussions. For example, the table of contents covers everything that would be discussed in a two semester principles course -- micro & macro separately. However, the discussions are insufficient, sometimes to the extent of misleading the reader. For example, discussion of the long-run average cost curve shows an area on economies OF scale (associated with multiple sizes of plot) flowed my a range of constant returns TO scale (TO which scale? Still talking about several scales), then an range of economies OF scale. Confusion is (1) reader never told that economies and discommodes BOTH exist over the entire range. Downward sloping and upward sloping reflect the NET economies. Beginning students wonder if the economies disappear, or if diseconomies only appear with very large sizes. It would be helpful to distinguish between technological and pecuniary, and between internal and external. Finally. Mixing discussion of returns OF and TO scale confuses with short-run diminishing returns TO scale with economies and diseconomies OF different scale alternatives.
