   Prob 10 7. One argument often heard against using fiscal policy to tame the business cycle is that the lags associated with getting a fiscal policy implemented are so long that when the program is finally passed and implemented, the business cycle has moved on to the next phase and the new program may not be necessary and may even be potentially destabilizing at that point. Does this argument seem reasonable? What counterarguments can you make in support of using fiscal policy?

   Prob 10 9. Our current personal income tax system is progressive: Income tax rates rise with rising incomes and are lower for low-income individuals. Some policymakers have favored a “flat tax” as a replacement for our modestly progressive income tax system. Most exemptions and deductions would be eliminated, and a single low tax rate would be applied to personal income. Would such a change in the tax laws alter the automatic stabilization characteristics of the personal income tax?

    Prob 10 10. In 1962 in a speech before the Economic Club of New York, President Kennedy argued that “…it is a paradoxical truth that taxes are too high today and tax revenues are too low—and the soundest way to raise revenues in the long run is to cut rates now.” Is President Kennedy’s argument consistent with supply-side economics? Why or why not?

    Prob 10 13. The last two of elections have seen more states and municipalities passing ballot measures legalizing some forms of soft drugs such as marijuana for medicinal or recreational purposes (“Marijuana Legalization Wins Majority Support in Poll,” The Los Angeles Times, April 4, 2013).

What would be some fiscal policy justifications for legalizing soft drugs?

    Prob 10 14. In June of 2009, The Economist discussed the ability to manage a country’s debt: Arithmetically, a government’s debt burden is sustainable if it can pay the interest without borrowing more. Otherwise the government will eventually fall into a debt trap, borrowing ever more just to service earlier debt. What kind of problems might cause a country to fall into a debt trap as described above? What policies enacted today could reduce the probability of falling into a debt trap?

What percentage of this economy’s GDP is spent on interest payments on its debt?
