How government spending and taxation shape economic growth, deficit dynamics, and long-term interest rates โ the macroeconomic backdrop every investor must understand.
FV, r, n) โ or type numbers directly: 10000 / (1 + 0.08)^1010000 / (1 + 0.08)^10When the government spends more than it collects in taxes, it runs a budget deficit and borrows by issuing Treasury bonds. This fiscal policy โ the deliberate use of spending and taxation โ is one of two levers for managing the economy (the other being monetary policy). For investors, deficit dynamics directly affect Treasury yields and the risk-free rate underlying all asset pricing.
Budget Deficit = Government Spending โ Tax Revenue. Deficit spending is expansionary (raises GDP); spending cuts or tax hikes are contractionary. The multiplier effect means a $1 increase in government spending raises GDP by more than $1 โ multiplier = 1 / (1 โ MPC). But crowding out can offset this: heavy government borrowing raises interest rates, reducing private investment. Debt sustainability requires growth rate > interest rate (r < g).
