High Income Disparity Leads to Low Savings Rates « naked capitalism

Citigroup Plutonomy reports in 2005 and 2006 by Ajay Kapur, Niall Macleod, and Narendra Singh as reported by Yves Smith:

In a plutonomy, the rich drop their savings rate, consume a larger fraction of their bloated, very large share of the economy. This behavior overshadows the decisions of everybody else. The behavior of the exceptionally rich drives the national numbers – the “appallingly low” overall savings rates, the “over-extended consumer”, and the “unsustainable” current accounts that
accompany this phenomenon….

Feeling wealthier, the rich decide to consume a part of their capital gains right away. In other words, they save less from their income, the wellknown
wealth effect. The key point though is that this new lower savings rate is applied
to their newer massive income. Remember they got a much bigger chunk of the
economy, that’s how it became a plutonomy. The consequent decline in absolute savings for them (and the country) is huge when this happens. They just account for too large a part of the national economy; even a small fall in their savings rate overwhelms the decisions of all the rest.

Yves here. This account rather cheerily dismisses the notion that there might be overextended consumers on the other end of the food chain. Unprecedented credit card delinquencies and mortgage defaults suggest otherwise. But behaviors on both ends of the income spectrum no doubt played into the low-savings dynamic: wealthy who spend heavily, and struggling average consumers who increasingly came to rely on borrowings to improve or merely maintain their lifestyle. And let us not forget: were encouraged to monetize their home equity, so they actually aped the behavior of their betters, treating appreciated assets as savings. Before you chide people who did that as profligate (naive might be a better characterization), recall that no one less than Ben Bernanke was untroubled by rising consumer debt levels because they also showed rising asset levels. Bernanke ignored the fact that debt needs to be serviced out of incomes, and households for the most part were not borrowing to acquire income-producing assets. So unless the rising tide of consumer debt was matched by rising incomes, this process was bound to come to an ugly end.

The US shows a negative relationship between income concentration and savings (data points 1929-2002, with 1940-1944 excluded, which is defensible, given widespread wartime rationing):

Canada shows the same downward sloping relationship, as does the UK (although the authors have to massage the data a bit more, with one downward sloping line for the period before 1990, with a shift for the 1990s period).

Debt Is A Political Issue - Paul Krugman Blog - NYTimes.com: "one audience member asked a really good question: if the problem is that interest rates are at the zero lower bound, why should we worry about government borrowing? After all, doesn’t that mean that the government can borrow at a zero rate?

Now, part of the answer is that you really don’t want governments financing themselves largely with very short-term debt — that makes them too vulnerable to liquidity crises. But even long-term rates are low — the real interest rate on 10-year bonds is below 1.5 percent.

And if you do the arithmetic of debt service, that really does seem to suggest that debt isn’t a problem. To stabilize the real value of debt, all the government has to do is pay the real interest on it. So suppose that we add debt equal to 100 percent of GDP, which is much more than currently projected; servicing that debt should cost only 1.4 percent of GDP, or 7 percent of federal spending. Why should that be intolerable?

And even that, you could argue, is too pessimistic. To stabilize the debt/GDP ratio, all you need is to pay r-g, where r is the real interest rate and g the economy’s real growth rate; and right now r-g looks, ahem, negative.

And this benign view of debt isn’t just hypothetical: countries have, in reality, run up immense debt/GDP ratios without going insolvent: see the history of Britain, above.

So what’s the problem? Confidence. If bond investors start to lose confidence in a country’s eventual willingness to run even the small primary surpluses needed to service a large debt, they’ll demand higher rates, which requires much larger primary surpluses, and you can go into a death spiral.

So what determines confidence? The actual level of debt has some influence — but it’s not as if there’s a red line, where you cross 90 or 100 percent of GDP and kablooie; see the chart above. Instead, it has a lot to do with the perceived responsibility of the political elite."
