What Exactly Would a Stronger Yuan Do for the US Economy?
Back in 2005, the World Bank estimated the Yuan to be undervalued by 10%, based on purchasing power parity. Other economic analyses have concluded an undervaluation of 20 to 25%. Let’s take the upper end of the these estimates and assume the Yuan is undervalued by 25%, and that China, acting for the good of the world, allows the Yuan to appreciate 25% against the dollar. What would that do for the US economy?
The most obvious and immediate effect would be an increase in prices. Consumer price theory tells us that that increases in exogenous costs such as tariffs are not fully reflected in final prices, but the cost is shared by producer and consumer depending on the elasticity of demand. The increase in prices directly translates into increased prices for consumer goods, for apparel, electronic goods, raw materials, food items, etc. It’s hard to see how that rise in prices would benefit American households, who are feeling the effects of 10.2% unemployment and falling home prices. It’s more likely that increased consumer prices would bring significant hardship.
In theory, an appreciation of the Yuan should narrow the trade deficit between the US and China. But it’s likely that the trade deficit won’t fall much (if at all), because consumers driven by low prices are likely to select goods from other low cost producers (Thailand, South Korea, the Phillipines, or India, for example).
Would an appreciation of the Yuan cause an increase in American employment? It’s hard to see how. There aren’t many US industries that are in direct price competition with Chinese exporters. Overall, the US economy is in a process of shifting back toward productive activity (including manufacturing), but such a shift is the product of many structural economic forces, not simply the relative value of the Yuan and the dollar.
As Obama urged China to allow the Yuan appreciate, Zhou Xiaochuan, the head of China’s central bank, fired back that the US needs to get its fiscal deficits under control and raise interest rates. Zhou is clearly correct that currency manipulation (in whatever direction) cannot help the US economy out of its malaise. Only fundamental economic changes can do that. But cutting the deficit in this economy will require massive spending cuts, while raising interest rates will cut off the monetary stimulus, no doubt deepening the recession.
If only it were as easy as blaming China.

Stimulus Blues
I recently had the opportunity to take an unoffical poll of my economist colleagues a the City College of San Francisco, where I teach. One of the areas of very strong agreement was that the US dollar is the most serious risk to the US economy (there was one dissenter out of six economists). The other area of agreement was that the US needs another stimulus, on the order of $500 billion. Here, I was the lone dissenter. (Several of my colleagues didn’t feel another stimulus was politically feasible; I don’t think another stimulus is desirable economically.)
My colleagues are in good company; Paul Krugman, the 2008 Nobel prize-winner in economics has called for a second stimulus, as has Robert Reich and many others. A majority of economists were in favor of the first stimulus, though there were also some prominent dissenters. I think the views of economists tend to mesh with the conventional wisdom that the government has to do something.
The problem is that doing something is rarely a good substitute for doing the right thing.
Economics has largely scrapped the distinction between necessary and surplus value; necessary value is the portion of value that reproduces the capital and labor that went into producing a good or service, while surplus value is the additional value of the product above the cost of production. Without this key distinction, it becomes impossible to distinguish between economic activities which are productive (directly produce surplus value) and unproductive (those that do not); we’re left with only GDP numbers, without a notion of where the value flows came from.
To try to increase GDP without considering whether we’re increasing productive or unproductive economic activity is dangerous in an economy like the US, where unproductive activity has been steadily rising over the last 60 years. This rise has been financed by growing debt and capital inflows to the US economy, but as these flows slow, unproductive activity becomes less and less viable. To put it simply, the future of the US economy is in agriculture and manufacturing, not in finance, retail, or advertising. While there will always be a place for finance and other unproductive activities in the economy, it must be recalled that government is also an unproductive activity. As government spending increases, it absorbs a greater portion of the economy’s total surplus, at the very moment when that surplus is most needed to restructure, innovate, and re-invest. That is a recipe for a lingering malaise, such as what Japan experienced in the 1990s.
This is the time for government to cut back, do less and spend less, to balance the budget, and to trim taxes. In short, the government should take the advice given to a man in a small pond, thrashing about in an effort to make the muddy water clear:
Be still; it will happen best on its own.

Ah, Krugman!
To sum up: A few months ago the U.S. economy was in danger of falling into depression. Aggressive monetary policy and deficit spending have, for the time being, averted that danger. And suddenly critics are demanding that we call the whole thing off, and revert to business as usual.The above is a quote from the marvelous Paul Krugman. I love him; and yet, he's so wrong right now.

Krugman vs. Austrian View of Booms and Busts
Just a quick note on the new, pessimistic CBO budget projections:This is a testable hypothesis. We shall see if it is the case that spending another $600 bil actually results in an addition of (only) $400 bil in debt in a decade.
1. These projections have no bearing on the case for a large stimulus now — none. Adding, say, another $600 billion to stimulus spending would, on net, add around $400 billion to debt a decade from now (net is less than gross because the stimulus expands GDP, which leads to higher revenues that partly offset the initial outlay.)
