Face Value

Two timely books open up this emergent field: Epigenetics by Richard Francis and The Epigenetics Revolution by Nessa Carey offer very different takes on how genes are regulated, and is more aligned with molecular biology.

Abstract

People pay attention to the appearance of others, and personal characteristics can affect many types of decisions. We ask, is there informational value in a face in a situation where trust and reciprocity can increase earnings? We use a laboratory trust game experiment where subjects are unable to observe a counterpart, must observe a counterpart, or can pay to reveal a counterpart's photograph. Both senders and responders are willing to pay to observe the photos, and we show that behavior, earnings, and efficiency are affected. When subjects are “face to face,” efficiency is enhanced, and senders have higher earnings. (JEL D12, D83, Z13)
