This table is similar to Table 25-1 except that here taxes vary with income while in Table 25-1 they did not. Alternatively one could say that Table 10-1 considers, 8.

Now consider a subsequent across-the-board reduction in income taxes of $250. Table 10-3 shows the new relevant data for national income, taxes, disposable income, and consumption. The new equilibrium level of income after the reduction in taxes is $_ The multiplier for the across-the-board change in taxes is 6. Why did it take a larger reduction in taxes to restore GDP to its initial level following the reduc tion in government purchases? 7. Question 4 asked you to analyze the impact of a reduction in income taxes. Was this reduction in taxes self-financing? That is, was the increase in GDP stimulated by the reduction in taxes large enough so that on balance there was no decrease in government tax revenues? (Be sure to compare
