Deuteronomy 15 has a dynamic stimulus plan:
Deu 15:1 ¶ At the end of [every] seven years thou shalt make a release.
Deu 15:2 And this [is] the manner of the release: Every creditor that lendeth [ought] unto his neighbour shall release [it]; he shall not exact [it] of his neighbour, or of his brother; because it is called the LORD'S release... KJV
Debt forgiveness can be a powerful stimulus. If, for example, you have some cash in the bank, you can think of that as a loan from you to the bank. Better go spend it. Should make everybody's CDS pretty expensive.
God also has some advice (NIV this time):
However, there need be no poor people among you, for in the land the LORD your God is giving you to possess as your inheritance, he will richly bless you, 5 if only you fully obey the LORD your God and are careful to follow all these commands I am giving you today. 6 For the LORD your God will bless you as he has promised, and you will lend to many nations but will borrow from none. You will rule over many nations but none will rule over you.
