Small Cap Investing and the Size Premium

Does Market Capitalization Matter?

It would certainly seem so, as the Russell 2000 has outperformed the Russell 1000 by around 5% so far this year (up 11% vs 6% as of 23/7/18).  With this in mind we turn a keen eye to papers on small-cap equities. 

The size premium is a factor anomaly that has been discussed in a variety of academic papers.  Does this premium exist, or is it merely a manifestation of survivorship bias?  If it exists, under what circumstances can it be captured? Does it pay to go active in EM small caps, or does indexing make more sense?
