The conventional wisdom is that consumer spending is what drives the U.S. economy. And consumer spending arises out of consumer confidence. Unfortunately, the signals along the road to economic recovery are mixed, what with the rising GDP growth and the dismal unemployment numbers. Its enough to leave investors scratching their heads. What barometers of consumer confidence will the coming week bring?

The TIPP Economic Optimism Index for November is scheduled for Tuesday, and the University of Michigan Consumer Sentiment Index for November is due out Friday.

Consumer borrowing fell for the eighth straight month in September. This record-setting streak is due largely to tightening by lenders, unemployment and the conservative preference to pay down debt rather than spend. This widespread fit of fiscal responsibility, economists fret, could prevent a recovery from taking root, since consumer spending is responsible for 70% of the U.S. economy. This conventional thinking, of course, overlooks the fact that an eventual increase in spending that isn't fueled by consumer spending will yield a recovery that's more likely to last.

According to the Federal Reserve, borrowing fell at an annual rate of $14.8 billion in September -- it's biggest drop since July and much larger than the $10 billion predicted by economists. The behavior is exactly what you'd find in people worried about losing their jobs or focused on rebuilding safety funds and investment portfolios. Those who want to borrow are finding banks won't be complicit this time, as they clamp down on lending practices.

There's a chill in the air and a slight up-tick in confidence. Holiday discounts are coming a bit earlier, too. For retailers, this has been a great combination, leading to the second consecutive month in which retail sales increased.

This follows more than a year of drops. Consumers aren't going crazy, but they are loosening their wallets a little bit. Consumer spending accounts for 70% of the U.S. economy, and the coming holiday season is where the action is -- for the retail sector and, consequently, for everyone else.

For the first half of 2010, almost two thirds of money managers are bullish, according to Barron's. In fact, 54% are bullish, and 5% are "very bullish." Responses suggest that the Dow Jones Industrial Average is expected to gain another 5% by the end of the year.

According to Barron's, "Today's bullish investors see the major stock indexes making steady progress through next June, amid signs the U.S. economy is on the mend after a searing recession."

Consumer spending had its largest fall this year, thanks to the end of the "Cash for Clunkers" program. And, incomes were flat. No change to the money coming in and a drop in the cash going out translates to an impediment to economic recovery.

In September, consumer spending fell 0.5%, the first decline in five months and the worst in nine. Wages and salaries dropped 0.2%, effectively offsetting the 0.2% up-tick in August. The economy did grow in the third quarter of 2009, hinting that the worst recession in 70 years may be coming to a close, but the tough September suggests we still have some work in front of us.

Consumer confidence ticked upward for the first time since 2007. Around the world, consumers are becoming more comfortable with the prospect of shelling out some cash, even if they're still approaching the notion with caution.

According to a survey conducted by The Nielsen Company between September 28 and October 16, 2009, consumer confidence was highest in India, with Indonesia and Norway following. Japan, Latvia, Portugal, and South Korea were at the other end of the spectrum, though South Korea did show a significant quarterly improvement.

Jobs are ready to make a comeback!

As usual, it all comes back to the consumer. Consumer demand increased, and spending follows demand, of course, which provides the fuel necessary for economic growth. When enough of this fuel is expended, we'll finally see an increase in jobs -- and relief from what is soon to be double-digit unemployment.

For the first time since the start of the recession, more companies are planning to add positions rather than cut them in the next six months.

By year-end 2009, we will see a more than $4 trillion pullback in credit lines. And we are a country that runs on credit. In fact, the entire growth in consumer spending from 1997 to 2008 was paid for with home equity lines and credit cards.

Credit standards are already impossibly high. My credit lines literally shrink every month because I do not use them. But what if I needed them? And I almost couldn't get a lease for a new car even though I have never missed a bill payment. The majority of people cannot borrow money and, therefore, cannot spend. This will not change in 2010.

Next: Reason #6: Excess capacity

Not only are consumers not spending, their actual attitudes toward spending have changed.

Even for the six people on the block who are flush with cash, frugality is the new chic. My neighbors, high-end Saab and Volkswagen types, just bought a Kia Sportage for their daughter (nice car, by the way).

A fear of a loss of income will continue to squelch consumer spending. Most people I know are fearful about their futures -- i.e., losing their jobs or seeing a cut in commissions, profits, or wages. This means they will hang on to their pennies in 2010.

Bottom line: Consumers drive 70% of GDP, and a meaningful recovery will not happen without their dollars.

Next: Reason #4: Changing consumer attitudes

Some of the jobs that have disappeared through this recession are gone forever, it seems. Even when the market turns, and even gains momentum, we could be stuck with a fairly weak employment market for a while. The recovery will take longer than we'd like, putting more distance between now and the top of the next market run. We've lost 7.2 million jobs since December 2007, and the predictions of some economists that we'll get them back by 2014 may actually seem optimistic.

Why is the recovery going to be such a grind? Check out the four major reasons after the jump.

The recession is only over if you ask the right people. While some sectors are starting to see the light at the end of the tunnel, consumers remain concerned. It may be tempting to listen to the experts over the average Joe, but the former don't control 70% of the U.S. economy. So, as long as people are worried abou unemployment (which continues to rise), the levels of debt they carry and whether they're at risk of foreclosure, the recession will live on in the hearts of those who write checks and swipe credit cards.

It's going to get worse before it gets better, according to Stone & McCarthy Research. Early 2010 has "the more troublesome outlook," as the economy will have to walk on its own, the research firm says. This year, it's had a pair of crutches: tax credits for first-time home buyers and the cash-for-clunkers program. So, if the stimulus hasn't taken hold by the end of the year, the first quarter could be a bruiser.

The firm adds that "continued growth in aggregate demand" is needed, bringing the discussion back to consumer spending . . . which is where it will always land. We're likely to see the 3.2% growth rate from July through September drop to 2.4% at the end of the year because the crutches will have been gone. And, let's not forget that unemployment is expected to break the 10% level next year.

Consumer spending may be down, but its share of U.S. economic activity has increased. So, we're now more dependent than before on the average Joe's open wallet to guide us out of the recession. A year ago, consumer spending accounted for 70% of the U.S. economy. Since then, it has edged up to 71%. The long-term average is approximately 65%.

The increase in consumer spending's share of the economy indicates that other sectors fell harder. Business and construction spending on new equipment have constricted at a record rate since 2008. This isn't unusual, though, as consumer spending tends to take a larger piece of the economic pie during downturns.
