    Class 3 - Macro Policy + Markets

    Structural differences between high and low tax countries: Differing definitions of social contract. Provision of services approach. Much bigger provision of public sector

    • So the US is in the lower 1/3 for taxes but upper 1/3 for spending per citizen, how? (spending relative to GDP is smaller but absolute quite large)

    Difference between the deficit and primary deficit

    The surplus at the end of the 90s

    • What would we use if we didn’t have a government bond? Don’t worry, we got hit by a recession and Medicare Part D
    • Norway, north sea oil budget surpluses
    • In the 90s, we ran a 4.5% budget deficit, now we’re at 7%

    Tax cut as mathematically equivalent to government stimulus. So stimulus either way but what’s the ground truth look like.

    • A tax cut always provides less stimulus than government spending
      • If you increase defense spending, 100% of that money goes into the economy but a tax cut could show up in a many ways (pay down debt, save, etc.)
    • Tax cut of the same size (%) will have a greater proportionate effect for those at the bottom end

    Pushing up interest rates b/c the gov borrows more, pushes the cost of cpaital (itnerest rates0, drives down the NPV of projects becuase it increases the WACC. What is the “savings” she refers to

    • Ricardio equivalence: When households see a stimulus (so G goes up)… so this is temporary, they believe taxes will come in the future. The private savings should offset the government stimulus

    “how would we respond to a crisis if we have less fiscal capacity”

    Savings is a flow, when interest rates are high, then I have more incentive to save. Does the market being higher want me to save more? Unpack that.

    Just take what you would get for an increase in G x m, so that’s effectively the tax shield of what would be government spending

    Automatic stabilizer:

    • UI is an automatic stablizler
    • Also, as you make less money, you have lower taxes.

    Greece

    • Why do we care about debt in relation to GDP? If debt becomes a larger % of GDP it signals that we’re not getting more out of the debt we’re taking on.
    • Eroding the real value of the fixed interest rate (high domestic inflation doesn’t help you w/ dollar debt)

    RUn a big budget deficit, then devalue currency. Print money (ask how this works?)

    Two body problem: GDP slows and deficit increases, amplifying each other
