FORTUNE – For the past few years, a tepid economic recovery has caused America’s biggest companies to hoard a growing stack of cash. It’s a thorny issue. Not just to the millions of jobless who wonder why corporate America can’t just use its plentiful cash reserves to hire more workers, but also to shareholders asking for higher returns on their investments.  But 2012 could turn out differently. Companies have slowly come around, with shareholders likely to see higher payouts this year. Even if firms only paid out a modest 10% of their liquid assets, it could raise annual disposable income by nearly 2%, according to a new report by Capital Economics. With more money in shareholders’ pockets, even if they naturally save a bulk of it, such a payout could still raise annual consumption by 1%.  If you believe the estimates, then it’s certainly a reminder that companies should really step up.  Last month, Apple AAPL announced it would pay its first dividend in 17 years, leading some to speculate if others in the tech world might think differently about their cash reserves. Though Cisco CSCO , Oracle ORCL and Microsoft MSFT pay dividends, the companies are still among the nation’s biggest cash hoarders.

Microsoft follows with approximately $52 billion and Cisco with about $47 billion. Google (GOOG) ranks fourth, with $45 billion. And now that Apple is giving its shareholders a payout, that makes Google the only tech company with a market value exceeding $100 billion that doesn’t offer a dividend.  Since the latest recession, executives uncertain about the economy have held onto their money. Cash levels at the end of 2011 rose to $672 billion from $42 billion at the end of the recession in mid-2009. If you include short-term investments, liquid assets nearly doubled to $2.2 trillion during the same period.  Indeed, that’s a lot of cash to go around. Companies obviously aren’t going to pay out all their cash reserves. If they did return that $2.2 trillion to shareholders, personal incomes would rise by nearly 20%.  It’s true raising dividends might not work for every company, but it’s hard to argue that it would exactly hurt executives. Even with Apple’s plans to dole out dividends and provide stock buybacks, the move isn’t expected to put a dent in Apple’s coffers. The plan is expected to cost the company more than $10 billion a year over the next three years, while the company attracts a sizable sum of cash – about $1 billion a week in the last holiday season alone.

And like the late Apple CEO Steve Jobs, who resisted giving dividends, tech companies would rather save cash for possible acquisitions and other investments. In a way, raising dividends might actually signal companies aren’t planning enough for future growth. Such arguments become less convincing during economic environments like today’s, since cash reserves keep rising and aren’t likely returning much for companies at a time when interest rates are at record lows.  To be fair, companies have started relaxing their purse strings. During the first three months this year, net dividend increased by 27.6% to $24.2 billion over the same period during the previous year, Standard & Poor’s reported Tuesday. There were 677 dividend increases during the first quarter, a 32% rise compared with the 510 increases during the same period in 2011.  “Dividends had another great quarter, with actual cash payments increasing over 11% and the forward indicated dividend rate reaching a new all-time high, with or without Apple,” said Howard Silverblatt, S&P Indices’ senior index analyst in a statement.  To be sure, he adds, payout rates remain historically low. The percentage of net income paid out in dividends, which historically averages 52%, remains near its lows at under 30%.  It remains to be seen where dividends go this year, but thus far they’re off to a good start. Perhaps a small boost in consumer spending will come next.
If companies don't want to spend their cash hiring more workers, they ought to consider paying higher dividends. The impact on personal incomes and spending might be more than they realize.
