A riddle.

You will know that I am coming From the jingle of my bell, But exactly who I am is not an easy thing to tell. Children, they adore me for they find me jolly, but I do not see them when the halls are decked with holly. My job often leaves me frozen, I am a man that all should know, But I do not do business in times of sleet or ice or snow. I travel much on business, But no reindeer haul me around, I do all my traveling firmly on the ground. I love the time of Christmas, But that's not my vocational season, And I assure that is because of a sound economic reason.

What am I?

---This one had me guessing for a little bit but I figured it out after a while.---
