Now that the election is over, President-elect Obama has a tough economic road ahead. The advanced GDP report of -0.3% suggests that the U.S. is in a recession. The $64,000 question is how long the recession will last. An examination of a few economic forecasting tools give an approximation of when then recession began and likely endpoints.

A widely used index of economic activity is the Chicago Fed National Activity Index [CFNAI]. The index is released monthly and is a weighted average of 85 indicators of economic activity. Since the index is calculated using monthly data it can be used as a leading indicator for quarterly GDP. The following chart shows the CFNAI since 1967 with recessions in red.

The Chicago Fed produces two indexes, a monthly index and a three-month moving average of the monthly index. The three-month moving average index smoothes any volatility in monthly numbers and is used for economic forecasting.

A zero value for the three-month CFNAI indicates that the economy is expanding at rate of growth that is consistent with its historical trend. An index reading below -0.70 following a period of expansion indicates that a recession may have started. A reading above 0.70 two years into an economic expansion indicates increased probability that a sustained inflationary period has begun.

The three-month CFNAI crossed below -0.70 in December of 2007 and is therefore the likely start date of the current recession. According to the NBER, since 1967 there have been 6 recessions. The longest recessions lasted 16 months and occurred from November 1973 to March 1975 and July 1981 to November 1982. The shortest recession started in January 1980 and ended in July 1980, for a total of 6 months. The average recession lasted for 10.8 months.

Using the NBER figures and a start date of December 2007, the following recession window can be interpolated:


From this table it is clear that the U.S. will not experience a short recession since that would have been completed in May of 2008. The most recent advance GDP report of -0.3% suggests that the recession may not end in mid-November 2008. The only end date left is a long recession with a potential end date of April 2009.

The start date of the recession is consistent with Federal Reserve models of the probability of recession. In a 2006 report, Jonathan Wright, a Fed researcher, developed a model for predicting the probability of a recession using the Treasury yield curve. The model developed used the 10 year - three-month spread and the effective fed funds rate. The following chart is from Wright's paper and shows the probability of a recession since 1964 using his Model B. (Recessions in red)

Model B was found to be a good predictor of recessions within 12 months of a high probability reading. Interestingly, it appears that the critical probability level for predicting a recession is 50%. Once the indicator reaches this level, there is high certainty that a recession will occur in the next 12 months.

Using Model B and current data yields, the following results from 1997-2008.


This graph illustrates that the probability of a recession in the next 12 months reached the critical level of 50% in the first quarter of 2007. Within 12 months, the three-month CFNAI crossed below -0.70 indicating a recession has begun. This provides more support for December 2007 as the start date for the current recession.

The Federal Reserve Bank of Philadelphia also publishes the probabilities of a recession in its Survey of Professional Forecasters [SPF] report. This data goes back to 1968 and shows the probability of a recession occurring in the next quarter. (Recession in red)

<

With this series, it appears that 40% probability is the critical level in predicting a decline in GDP in the next quarter. Interestingly, the probabilities breached the 40% level in the first quarter of 2008. While not an exact match with Wright's Model B or the CFNAI data it is fairly close and can serve as additional evidence that the current recession began near the end of 2007 and the beginning of 2008.

After falling below 40% for one quarter, the Anxious Index breached the 40% probability mark again in the third quarter of 2008. This suggests that forecasters are expecting a decline in GDP for at least one more quarter. This projection means that the recession will last until March 2009, which is consistent with the long recession projection of April 2009.

The next CFNAI report will be released on November 24, and could provide clues regarding the duration of the economic malaise. Watching the 10 year - three-month spread and effective rates will also be of utmost importance.

    i disagree that you have or can make a case that the recession began in 2007. yes, the economy was showing signs of duress, but it was still expanding.

    This is a new era folks and new "norms" are going to be established.

    We have not simply slowed down on our way to picking up speed again in a few months. The dynamics of the entire system have changed and are still evolving.

    Keep your money safe and wait for the dust to clear. Don't try to buy the bottom; instead wait until it's clear that it's past as there's plenty of money to be made between the bottom and top without timing both perfectly.

    The housing/credit/financi... troubles are just a symptom. Our troubles emanate from the big bankers/wall street. When the Federal Reserve was formed our doom was sealed. Then these "big wheels" found out they could make even more money by shipping the United States manufacturing overseas. We needed that for an economic base. It's gone.
    The "Big Wheels" are now having trouble fleecing (through the federal reserve/Wall Street) the citizens because as a whole, we are broke. Too bad for the "Big Boys". Well, they can keep going for a little while on the bail-out money. As for when "it" ends, I don't believe I will live to see the end.

    While the author has made a good case backed with data - I cannot say the same about the commentators, who strike me as a rabble of sore neo-con losers.

    Very well thought out and perceptive assessment. I think much of the population thinks that, given a few more months, maybe even a year, things will be back to "normal" and we will be back on the road to ever-increasing prosperity. I don't really see it that way myself either, as our insurmountable debt, combined with all the other factors you mentioned, will be a tremendous ball and chain on future prosperity.

    Honestly, I hope the youth takes advantage of this down stock market to pad their early retirement accounts with nicely valued stocks. Something good has to come from it. My only fear with the recession now is if it drags into late 2009 we're going to cross that threshold where more of the baby boomers hit retirement age and their spending habits decrease. If the baby boomers act like previous generations their retirement could suck some serious life out of the general economy.

    @The Sentinel: No doubt there are always those among us who would repress and be tyrannical -- but let's not succumb to the notion that population control techniques are the answer!! It's quite ironic that the push for that not only is precisely what has led to part of the ills we currently have to deal with, but *also* is what Hitler, Mao, & Stalin attempted! Look into the history of Planned Parenthood -- its founders were population control theorists who were into eugenics and feared population growth. The results are that we now face the new tyranny of forced contraception in Asia and Africa, underpopulation in Europe and America...and political instability as a result -- large numbers of people in certain religions that do not allow birth control (ahem...Islam) have migrated into Europe, and the results are NOT going to bring political peace and prosperity! I think we have seen that clearly the last few decades?!

    It's actually time for Western nations to rethink their seeming distaste for conservative family values and rethink the possibility that having children and raising them with old-fashioned values, strong character, and a good work ethic is what built up the American nation and would serve us well again. Methinks it would bring much more satisfaction than placing so much value on our stock portfolio and having 2nd homes, but only 1, maybe 2 kids...or in some cases none (but always 2 dogs, of course....)

    We've had it wrong and its time to rethink.

    It is not true that the world saw an increase in population due to advances in medical science. The vast increase occured due to advnces in civil engineering- clean water systems, sewage and sanitation systems- and the Green Revolution, where fossile fuels were used to fix nitrogen and develop agricultural mass production based on mechanization and production of monoculture crops. This is unlikely to be sustainable in the face of deminishing availablity of easily assessible carbon based fuels, as well as due to the effect that increased CO2 has on the climate, which may affect agriculture and disease prevalence in unpredictable ways. Population growth is a fundemental problem, as we are stressing the resources available. Genetic modification of food crops holds out significant hopes for improved food production, although this has also proved to have some rather unpredicted adverse outcomes. Historical lesions may be of limited value in predicting where the economy goes from this point, as the rate of change in multiple aspects of our society and the global situacion has created conditions unlike any in the past.

    One day it will end....but all I want to know is : is it possible to avoid another nasty surprise by -say-2015? over confidence,over production,excessive capacity/credit expansion at the time of ''normal periods'' created this mess. Will our policy makers learn some lessons or will it be a case of ''history repeating itself '' once again

    personally i feel the marxian theory is right: capitalism will destroy itself...but dont worry . communism is already dead!! the synthesis will be on the lines of politico/economic system in countries like india sans indias own corruptions and inefficiencies.

    i am not a hotshot mba or phd.I am adding this I want people to believe me!!!

    Great post and the analysis you had is excellent. Despite the recession dragging on and hitting tech espically hard, it is good to see another optimistic viewpoint (relatively speaking). I think the recession will be over as fast as it started, though the structural changes will last for much longer. Now is the time to make the best of the opportunities available.

    I won't predict on when the recession will be over but one thing for sure it will not be in the next 6 months. Looking at the unemployment rate which is increasing every month, which will cause ppl to spend less due to uncertainty. Demand will only decrease and it is a negative spiral effect. The only way for things to get better is for companies to stop cutting staff even when they are still doing well. Cutting staff = less consumption = less profit.

    After 8 years of Republican Policy. This is the result. Now, hopefully the newly elected Democratic President will be able to make the right adjustments and address the damage of which he inherited. The financial state of the Union is purely based on the result of 8 years of Republican Fiscal policy.

    I have no argument for anyone on the results of the Republican direction for the country. I am living with it. From the thousands of sources that I have found on this issue, the overall view is that banks were derregulated, created their own faulty lending practices, sold the loans off to someone else for a profit.

    Subprime lending only started under the Republican Administration and the Republican controlled congressional branch. These problems did not exist under Clinton because there was still oversight into the lending practices of banks.

    As far as the recession is concerned. I have never lived through something as damaging as the last 8 years of Repbulican policy has yielded. I pray for our country and for our new President who has more to say than, "So what" or that we are a bunch of whiners for being upset that our jobs are gone and our life savings has been demolished. The Republicans borrowed 100 percent of the money for the War in Iraq. That cost over a Trillion dollars. There were no weapons, so, what a costly mistake. Then they spend another 800 billion or so on the first knee jerk stimulous. This was constructed by the Republicans not Democrats.

    Tax cuts are nice, but over the last 8 years, they borrowed money to give them. Then gave the lions share to the wealthies Americans. 1%. That was Hundreds of Billions of dollars.

    The Borrow and Spend Republicans are by far to blame for this whole situation. I do not know if there is a true fiscal conservative in government.

    The last fiscal conservative we had in our government was BIll Clinton. Boy what we would give to have those prosperous days back.

    The Republicans also stated that sending the white collar jobs to India and China would be good for our economy. Missed the boat on that one. Now they have middle class, and ours is shrinking.

    Bottom line, middle class and below circulate and spend the money. The top end hoards and stores the money. Trickle down economics has never worked. Did not work for Republican Herbert Hoover, Republican George H W Bush, and now not for President Bush and Cheyney.

    Until the money circulates, the economy will not return. That is a fact. Until Americans are able to pay as they go (Bill Clinton's Plan). The Democrats are also for the American worker, where the Republicans for for the elite and few. It will never trickle down, so we should never try that again.

    Solutions:
    Bring jobs back to the US so that the money can be generated here and circulated through our economy.
    Cut taxes on the middle so the money can circulate through the economy.
    Require the wealthies Americans to pay their fair share of the burden.

    I could go on.

    What a mess the Republicans have created for us. Two wars, and economic crisis. All cost money, all cost your money.

    Next time we put a cowboy in charge, make sure has not failed at just about every business he has been involved in.

    Sincerely,

    A true American.

    "When the Democrats pass all their Socialistic policies and programs
    > our country will look like a decadent European Society."

    Really, you should be so lucky. At the moment the Euro is up vs the pound and the US dollar better than usual and most European countries have no where near the housing crisi the US has on its hands, the expensive military expansionisti policies of the US or the terrible reputation the Bush administration has given it. I am pro capitalism and pro USA the way it used to be run prior to Bush so dont get me wrong but there is a worldwide sentiment and in some cases a morbid desire to see the worlds biggest superpower falll flat on its face because of the greed of its own capital / debt markets. I hope this will not be the case but I think what we are about to witness is a global shift of power and growth across the globe to where growth is still needed. Read Asia, Europe etc. The US markets have almost reached growth saturation save for those industries now investing abroad such as in China, Russia, and India. I still think the emerging markets could keep the US banks afloat while the housing market completes its natural adjustment.
