This problem revisits Denises net present value calculation regarding the decision to invest in specialized training which was discussed in the inset entitled Calculating the Net Present Value of a Human Capital Investment. The calculation performed in the inset (referred to subsequently as the initial calculation) was based on a set of assumptions. Recalculate the net present value of Denises training investment for the following situations: [Hint: You can use a spreadsheet program like Excel to calculate net present value.]

Reminder: The initial NPV calculated in the text is $18,330.

The discount rate is .10 instead of .05. (All other parts of the initial calculation remain the same). What does this tell you about the effect of an increase in the discount rate on the training decision, all else equal?

Salary foregone during training is $30,000 instead of $20,000. (All other parts of the initial calculation remain the same.) What does this tell you about the effect of an increase in training costs on the training decision, all else equal?

Additional earnings from training are expected to be $5,000 per year instead of $6,000. (All other parts of the initial calculation remain the same.) What does this tell you about the effect of a reduction in annual benefits on the training decision, all else equal?

Expected work life after training falls from ten to five years. (All other parts of the initial calculation remain the same.) What does this tell you about the effect of a shorter work life on the training decision, all else equal?
