At the beginning of the year, Mr. L put $50,000 cash into an investment. At the end of the year, he received a check for $5,000, representing his annual return on the investment. Mr L's marginal tax rate on ordinary income is 28%, However, his return on this particular investment is a capital gain taxed at 15%.
At the beginning of the year, Mr. L could have invested his $50,000 in a business with a 12% annual return. However this return would have been ordinary income rather then capital gain.
Considering the fact that Mr. L could have invested in this business, how much implicit tax did he pay with respect to this investment described in the preceding problem?
