Here’s how wikipedia explains a balance sheet recession:
Balance sheet recession
The bursting of a real estate or financial asset price bubble can cause a recession. For example, economist Richard Koo wrote that Japan’s “Great Recession” that began in 1990 was a “balance sheet recession.” It was triggered by a collapse in land and stock prices, which caused Japanese firms to have negative equity, meaning their assets were worth less than their liabilities. Despite zero interest rates and expansion of the money supply to encourage borrowing, Japanese corporations in aggregate opted to pay down their debts from their own business earnings rather than borrow to invest as firms typically do. Corporate investment, a key demand component of GDP, fell enormously (22% of GDP) between 1990 and its peak decline in 2003. Japanese firms overall became net savers after 1998, as opposed to borrowers. Koo argues that it was massive fiscal stimulus (borrowing and spending by the government) that offset this decline and enabled Japan to maintain its level of GDP. In his view, this avoided a U.S. type Great Depression, in which U.S. GDP fell by 46%. He argued that monetary policy was ineffective because there was limited demand for funds while firms paid down their liabilities. In a balance sheet recession, GDP declines by the amount of debt repayment and un-borrowed individual savings, leaving government stimulus spending as the primary remedy.[7][12]
Lrt’s see it again with my comments in bold:### Balance sheet recession
The bursting of a real estate or financial asset price bubble can cause a recession.
Yes and no. As JJ pointed out, a bursting of a bubble requires, by definition, a bubble in the first place. By definition again, a bubble is an untenable situation, doomed to burst. So yes, the bursting of the bubble can cause a recession, AE definiately agrees with that. But again, as JJ pointed out, the real cause of the whole cycle is whatever caused the bubble, which Koo doesn’t discuss.
For example, economist Richard Koo wrote that Japan’s “Great Recession” that began in 1990 was a “balance sheet recession.” It was triggered by a collapse in land and stock prices, which caused Japanese firms to have negative equity, meaning their assets were worth less than their liabilities.
Correct, as far as it goes. See above.
Despite zero interest rates and expansion of the money supply to encourage borrowing, Japanese corporations in aggregate opted to pay down their debts from their own business earnings rather than borrow to invest as firms typically do.
Very true. However, you say that as if it’s a bad thing, which it isn’t. It’s exactly what they should be doing.
Corporate investment, a key demand component of GDP, fell enormously (22% of GDP) between 1990 and its peak decline in 2003.
Absolutely, no corporate investment means no increased production, because where else is increased production going to come from. The question is, that under normal circs, recessions don’t last 13 years according to AE, if the economy is left to itself. But of course the Japanese economy was not left to itself.
Japanese firms overall became net savers after 1998, as opposed to borrowers.
So they paid off their debts?
Koo argues that it was massive fiscal stimulus (borrowing and spending by the government) that offset this decline and enabled Japan to maintain its level of GDP.
Oh absolutely. But GDP is just a number. If the govt taxed everyone 100%, printed up trillions of dollars, and borrowed trillions more, then spent it all on cocaine parties for Obama, that would show up as a positive in GDP. But it is of no benefit to the economy, as I hope everyone understands. So maintaining ones GDP is not neccessarily a good thing.
In his view, this avoided a U.S. type Great Depression,
Non sequitor. See above.
in which U.S. GDP fell by 46%.
That’s like saying "I hit the guy with a hammer and broke his arms and legs, but I saved him from getting his skull smashed [by me].
Japan only suffered from govt spending, as every economy must [One must study a bit of AE to know why this is so]. Left to its own devices, it would have been better off.
He argued that monetary policy was ineffective because there was limited demand for funds while firms paid down their liabilities.
Monetary policy is always ineffective, or rather always bad for the economy [Again, knowledge of AE required here]. Maybe he means the delay of the inevitable bust was not posponed by monetary policy, because the Japanese quite rightly paid off their debts instead of borrowing more.
Now there is a subtlety here. In fact two subtleties.
1. Sometimes a business should be borrowing money and expanding [if there is money to be made doing so], sometimes it should be paying off its debt [if expansion will not earn a profit given the state of the market for the business’s product]. It is a pure business decision dependent on the highly individual situation the company is in. Certainly no economist or govt beaurocrat knows what’s right for a copmpany. It’s owners and management have a much better idea of what to do. That’s why they are the ones running the company and the beaurocrat and economist aren’t. So Koo’s assumption that paying down debt as opposed to expansion was a sad event and a big mistake is itself sad and a big mistake.
2. Koo is also making a huge error assuming [with no foundation] that if GDP is zero, things are bad. An economy does not always need growth. Soemtimes it needs creative destruction, as it fixes up the blunders made in the past. For example, if the govt subsidized the horse and buggy industry heavily, and many buggy factories were built, there nothing to do but put some time and resouces into destroying those factories and recycling their components into something useful, like auto factories. There will be a decline in buggy sales, firing of buggy makers, in short a recession, but it must be done.
In a balance sheet recession, GDP declines by the amount of debt repayment and un-borrowed individual savings,
Which, again, is not neccesarily a bad thing.
leaving government stimulus spending as the primary remedy.[7][12]
One more remedy like that and the patient will die.
