in geographic areas with a combination of higher household debt and larger price declines. When housing prices fall, poorer homeowners (with a larger proportion of their net worth in their home) are hit the hardest financially and reduce their consumption relatively more than wealthier households. Declines in residential investment preceded the recession and were followed by reductions in household spending and then non-residential business investment as the recession worsened. Effects on economic growth Ezra Klein wrote in August 2011: "[W]hat distinguishes crises like this one from typical recessions is household debt. When the financial markets collapsed, household debt was nearly 100 percent of GDP. It’s now down to 90 percent. In 1982, which was the last time we had a big recession, the household-debt-to-GDP ratio was about 45 percent. That means that in this crisis, indebted households can’t spend, which means businesses can’t spend, which means that unless government steps into the breach in a massive way or until households work through their debt burden, we can’t recover. In the 1982 recession, households could spend, and so when the Federal Reserve lowered interest rates and made spending attractive, we accelerated out of the recession. The utility of calling this downturn a “household-debt crisis” is it tells you where to put your focus: you either need to make consumers better able to pay their debts, which you can do through conventional stimulus policy like tax cuts and jobs programs, or you need to make their debts smaller so they’re better able to pay them, which you can do by forgiving some of their debt through policies like [mortgage principal reduction] or eroding the value of their debt by increasing inflation. I’ve heard various economist make various smart points about why we should prefer one approach or the other, and it also happens to be the case that the two policies support each other and so we don’t actually need to choose between them. All of these solutions, of course, have drawbacks: if you put the government deeper into debt in order to help households now, you increase the risk of a public-debt crisis later. That’s why it’s wise to pair further short-term stimulus with a large amount of long-term deficit reduction. If you force banks to swallow losses or face inflation now, you need to worry about whether they’ll be able to keep lending at a pace that will support recovery
