- Again, the following graph depicts the market for loanable funds. An investment tax credit effectively lowers the tax bill of any firm that purchases new capital in the relevant time period. Suppose the government repeals a previously existing investment tax credit. Shift the appropriate curve(s) on the following graph to show the impact of this policy.
