Is it raining dividends where you are?

Some of the market's better performers are easing up on their purse strings, sending more money out to their shareholders.

Readers of the Income Investor newsletter can certainly appreciate that kind of thinking. Let's take a closer look at four of the companies that inched their payouts higher this past week.

Let's start with Western Union (NYSE: WU). The global payment giant will be sending more money to its shareholders in the form a 14% boost to its quarterly disbursements. Western Union's new rate is $0.08 a share. It's not the only way that Western Union is returning money to its investors. It completed a $525 million stock buyback earlier this year.

Marsh & McLennan (NYSE: MMC) is also on the move. The insurance services provider announced meatier distributions during Thursday's annual shareholder meeting. Marsh & McLennan's new quarterly rate of $0.22 a share is a 5% upgrade.

Dr Pepper Snapple Group (NYSE: DPS) is also a fizzy lifting drink, carbonating its quarterly dividend by 28% to $0.32 a share. The beverage maker has only been public as a stand-alone company for three years, but it has now come through with its second consecutive annual increase.

Finally, we have Analog Devices (NYSE: ADI) digging deeper. The integrated circuits giant has been jacking up its payouts since 2003, so why should 2011 be any different? Analog Devices is improving its quarterly rate by 14% to $0.25 a share.

Some of these moves may not seem like much, but it's clearly better to see companies increasing their yields than slashing them. These stocks join electric and natural gas utility Xcel Energy (NYSE: XEL) and bank-based financial services provider KeyCorp (NYSE: KEY) in juicing up their yields. Security specialist ManTech (Nasdaq: MANT) initiated a dividend policy.
