Does a one-time fiscal expansion cause a one-time price level rise?
Core argument: In fiscal theory, a one-time $5 trillion fiscal blowout produces a one-time rise in the price level just large enough to inflate away $5 trillion of debt value, after which inflation stops even if the Federal Reserve does nothing.
A one-time $5 trillion fiscal blowout causes a one-time rise in the level of prices, just enough to inflate away the value of the debt by $5 trillion. Then inflation stops, even if the Federal Reserve does nothing. The Fed is still important in fiscal theory. The Fed bought about $3 trillion of the new debt and converted it to interest-paying reserves. Giving people checks backed by reserves is arguably a more powerful inducement to spend than giving people Treasury bonds. Now, by raising interest rates, the Fed lowers current inflation but at the cost of more-persistent inflation. That smoothing is beneficial. These are core propositions of fiscal theory, stated ahead of time and at odds with conventional theories.
