What is supply side policy?

Economic growth results from more and better labor and capital being supplied to the markets (as opposed to, say, do-it-yourself work at home). Supply-side economics is all about incenentives for working harder and smarter, incentives to learn new skills or relocate, incentives to start a new business, and incentives to save and invest. This involves minimizing government obstacles to productive acitivity, including unpredictable regulations, unstable monetary policies, and punitive marginal tax rates on adding to personal income and thereofore adding to national income, or GDP.
