Overall, a little more mathed up than some other intro books. Works if students have the background, a point of issue if not.Pretty good, but lacking Krugman's editorialized voice that is familiar to his work in the Times. Below is further thoughts not as specific to this book, but raised from a semester working with it. There are many interesting concepts that come forth in the study of basic economics. One of the most interesting things is the concept of the opportunity cost. It is easy to think of the accounting cost of an item. How much does that movie cost? Well, a ticket can be had for ten dollars. Nevertheless, the true cost of something is not just the dollar amount. The true cost is what you must give up in order to do something. Therefore, the opportunity cost is not just the ten dollars, but also the cost of the next best thing that you might be doing. Going to that movie is added to the cost of not studying for that exam (Krugman & Wells. p. 7). Most people have an implicit understanding of the concept, but it is not formally codified until the formal study of economics understands. A second interesting thing is the topic of fractional reserve banking. It is easy to take banking institutions for granted when thinking of the economy. They work within the economy, but they have an essential role in expanding the money supply. Banks have money, but to grow their own profits, they have to grow their balance sheets. Through lending, banks create money. For example, a bank starts with $100,000. It can then lend an amount up to the reserve ratio, 10% in this example. That means it lends $90,000 and keeps $10,000 on its books. The amazing thing is that it is not done. In our model, one bank stands in for the whole banking system.
