How can I test if one predictor variable in a regression is significantly better than another predictor variable?
i.e. If I regress X against A I get an r^2 of .99 and when I regress X against B I get .98. I need a test to see whether this difference is statistically significant. [more inside]

Are there any online fantasy stock market simulations that let you invest in international stocks? Or, if not, Asian stocks? I currently use Vritual Stock Exchange, which is limited to NYSE stocks.

Why do stock exchanges still close? It's nice for the traders to get some time off, but in this modern age where you no longer have to stand on the floor shouting at people, is it still necessary? Does it have some economic function?

What is the advantage of owning stock which has voting rights? These guys
(the first 20 posts, specifically comment #17) imply that stock which has voting rights will trade at a premium. Furthermore, this Berkshire memo
mentions that there will fluctuation and difference in supply and demand between two types of stock that have a constant valuation ratio despite having differing voting rights.
What is it about voting rights that would add or decrease value to a company's net worth? Most of the links I've checked seem to only confirm that yes, there is a difference.
