It's a pretty rough morning on Wall Street, so here's some countercyclical soothsaying from Casey Mulligan:
It’s important to keep in mind, too, that the financial sector has had a long history of fluctuating without any correlated fluctuations in the rest of the economy. The stock market crashed in 1987 — in 1929 proportions — but there was no decade-long Depression that followed. Economic research has repeatedly demonstrated that financial-sector gyrations like these are hardly connected to non-financial sector performance. Studies have shown that economic growth cannot be forecast by the expected rates of return on government bonds, stocks or savings deposits.[...]One important indicator is the profitability of non-financial capital, what economists call the marginal product of capital. It’s a measure of how much profit that each dollar of capital invested in the economy is producing during, say, a year. Some investments earn more than others, of course, but the marginal product of capital is a composite of all of them — a macroeconomic version of the price-to-earnings ratio followed in the financial markets.When the profit per dollar of capital invested in the economy is higher than average, future rates of economic growth also tend to be above average. The same cannot be said about rates of return on the S.& P. 500, or any another measurement that commands attention on Wall Street.Since World War II, the marginal product of capital, after taxes, has averaged 7 percent to 8 percent per year. (In other words, each dollar of capital invested in the economy earns, on average, 7 cents to 8 cents annually.) And what happened during 2007 and the first half of 2008, when the financial markets were already spooked by oil price spikes and housing price crashes? The marginal product was more than 10 percent per year, far above the historical average. The third-quarter earnings reports from some companies already suggest that America’s non-financial companies are still making plenty of money.Let's hope. So long as the damage remains contained to the stock market, it's rapidly reversible. The Dow can rise as quickly as it can drop. If it begins to manifest in unemployment numbers and shutter storefronts, that sort of economic damage takes a bit longer to undo. Which is why I'd feel better about things if, in addition to the Bailout and associated rescue measures, Congress was acting as if it's serious about a major stimulus package to pump cash into the economy.
