How much is an Associates degree in business worth on top of a CS degree?

I'm graduating soon and curious what sort of value, if any, a typical employer would place on my having a 2-year business degree in addition to 4-year CS degree.

What about a 2-year web development degree?

Does only the Bachelors matter or do the others somehow indicate having other useful skill sets? (And therefore be worth paying a little extra for.)

The reason I ask is Joel Spolsky recommends people take a course in Microeconomics, and that's included among other things in such a degree. Do businesses value employees with business education in addition to their primary skill sets, and if so, approximately how much do they value these employees? As in, how much additional pay or promotion consideration might there be?

Thanks.
