Whose Expectations Augment the Phillips Curve?

My first economics journal publication is now available online in Economics Letters. This link provides free access until November 9, 2015. It is a brief piece (hence the letter format) titled "Whose Expectations Augment the Phillips Curve?" The short answer:

"The inflation expectations of high-income, college-educated, male, and working-age people play a larger role in inflation dynamics than do the expectations of other groups of consumers or of professional forecasters."
