for studying accounting in Figure 6.2 "The Marginal Benefits of Studying Accounting" Similarly, we can find the marginal cost of the second hour studying economics That requires giving up the fourth hour spent on accounting Figure 6.2 "The Marginal Benefits of Studying Accounting" tells us that the marginal benefit of that hour equals 2—that is the marginal cost of spending the second hour studying economics Figure 6.3 "The Marginal Benefits and Marginal Costs of Studying Economics" shows the marginal cost curve of studying economics We see that at first, time devoted to studying economics has a low marginal cost As time spent studying economics increases, however, it requires her to give up study time in accounting that she expects will be more and more productive The marginal cost curve for studying economics can thus be derived from the marginal benefit curve for studying accounting Figure 6.3 "The Marginal Benefits and Marginal Costs of Studying Economics" also shows the marginal benefit curve for studying economics that we derived in Panel (b) of Figure 6.1 "The Benefits of Studying Economics" Attributed to Libby Rittenberg and Timothy Tregarthen Saylor URL: http://www.saylor.org/books/ Saylor.org 300
