the evidence suggests that automatic stabilizers are effective and should not be ignored

From Antonio Fatas and Ilian Mihov on the Global Economy:

"Fiscal policy

I attended today a very interesting conference on the role of fiscal policy at the IMF. I presented a paper on the role of automatic stabilizers. It is interesting that there are very few academic papers that have looked into the effectiveness of automatic stabilizers. In my paper I argue that the evidence suggests that automatic stabilizers are effective and should not be ignored. I also find that in recent years countries with smaller automatic stabilizers have compensated with more aggressive discretionary fiscal policy (e.g. the US has smaller automatic stabilizers than Europe but in the current crisis has used discretionary fiscal policy more aggressively). The program of the conference and copies of the papers can be found at the IMF web site.

If the link above stops working, you can find a copy of my presentation here.

"Discre(onary fiscal policy or automa(c stabilizers?
• At the end the debate depends on our views on the
quality of fiscal policy ins(tu(ons. If we trust
governments to use discre(on op(mally (and act
quickly during recessions), the addi(onal flexibility to
adapt their ac(ons to the specific shocks that are
hisng the economy makes discre(on superior to
automa(c stabilizers.
• But if there are implementa(on lags or we simply do
not trust government to produce op(mal responses
to recessions, then automa(c stabilizers dominate"

I would argue that the best Automatic Stabilizer would be a Guaranteed Income. For one thing, it's actually Automatic. It's also defined and certain, which is extremely important during a panic.Friedman also offered a similar proposal that Brittan likes, and I do as well:

"a 1948 paper by Milton Friedman entitled A Monetary and Fiscal Framework for Economic Stability, reprinted in Essays in Positive Economics (1953).

I found this early essay much more helpful than his better-known later proposal for a constant growth of the money supply. The 1948 paper contained four proposals:

First, a long-term policy of determining government expenditure on goods and services, either in money or real terms, entirely on the basis of the community’s desire and willingness to pay for such services.

Second, a predetermined programme of transfer payments for items such as pensions and unemployment pay. “Such payments will be high when unemployment is high and low when unemployment is low.”

Third, a progressive tax system primarily based on the personal income tax. The rates set should be sufficient to balance government spending at a hypothetical level of national income corresponding to “reasonably full employment at a predetermined price level”.

Fourth, budget deficits would be financed entirely by the creation of money by the Fed and surpluses used to retire money. This would best be accomplished by adopting the 100 per cent reserve proposal for banks, “thereby separating the depositary from the lending functions of the banking system”.

The first three proposals look at first sight like the “automatic stabilisers” that governments came to rely on as the main fiscal contribution to economic stability before the present emergency. But there is a crucial difference. In a recession, governments would not have to forecast the path of recovery, as the British government has done, or the timing of the return to budget balance. In a normal cycle, the return would be automatic. But, if forebodings of secular stagnation, with the desire to save at high employment levels exceeding investment opportunities, were fulfilled, then budgetary stimulants would continue as long as necessary."

The point, again, as I see it, is to make the Automatic Stabilizers actually automatic and predictable.

Whenever the US stock market goes up, the dollar goes down (relative to the Euro).

TO BE NOTED: Antonio Fatas and Ilian Mihov on the Global Economy


"The stock market and the value of the US dollar

I already wrote a note on this topic earlier in the blog but I thought it was useful to refresh the discussion with a picture. See below a picture of the evolution of the US stock market and the USD/EUR exchange rate since January 1st, 2009. The correlation between these two series is close to 0.9 (you get a similar correlation if you look at a longer series that starts in the summer of 2008). Whenever the US stock market goes up, the dollar goes down (relative to the Euro).


This correlation is not easy to explain with traditional macroeconomic models (to some this might not be a surprise given how bad some of our traditional macroeconomic models have helped us navigate through the current financial crisis,...).

To explain exchange rates we normally look for changes in the economic fundamentals of one economy relative to another (the exchange rate is by definition a bilateral variable). If this was just news about the US economy, what is normally assumed (and, under certain assumptions backed by economic theory) is that good news about the US economy get reflected in an appreciation of the currency. But here we have the reverse, the dollar depreciates when the US stock market does well.

Of course, if we truly want to make a relative statement about the US versus Euro economies we are missing information on the Euro countries in the chart. We know that during these months the behavior of these stock markets has been almost identical, influenced by news about the global economy. So, in some sense, it is not clear whether this is a correlation between the US stock market and the exchange rate or between global equity markets and the exchange rate. Should there be a correlation between global equity markets and a currency? It cannot be that all currencies appreciate when equity markets are doing poorly (some currencies need to appreciate!). But the US dollar is not just a regular currency. We are constantly reminded these days that the US dollar is still perceived as the currency of the world and that the only true "safe assets" are assets denominated in US dollars (treasury bills). If that's the case, bad news about the global economy trigger a "flight to quality" and this means moving away from equity but also away from currencies other than the dollar. This is consistent with the picture above although it is unclear how to make this consistent with other mode fundamental theories of the exchange rate (or the stock market) that are relevant at longer horizons -- but in times of panic, who cares about longer horizons?

If this the explanation for the correlation above, then we should expect that as signs of the economic recovery become strong, there will be a corresponding move away from the US dollar, which could lead to a significant depreciation (and more so if the US dollar starts losing its status as the safest currency in the world).
