Monetary Policy and Fiscal Policy
Their tools, their histories, their interactions, and the debates that define contemporary economic governance
Two great levers of macroeconomic management have shaped American economic history: the Federal Reserve's control of the money supply and interest rates, and Congress and the President's control of spending and taxation. They operate through different mechanisms, are controlled by different institutions, and are subject to different political constraints. Their interaction -- sometimes coordinated, sometimes conflicting -- has determined the pace of recoveries, the distribution of economic gains, and the political sustainability of economic arrangements.
What Each Policy Does
Monetary policy changes the cost of money; fiscal policy changes the quantity of spending. Both aim at the same economy through different channels.
History of Fiscal Policy
