SLAVERY AND NUMBERS GAME

Gutman emphasizes the slaves' responses to their treatment at the hands of slaveowners. He shows that slaves labored, not because they shared values and goals with their masters, but because of the omnipresent threat of 'negative incentives,' primarily physical violence.

In his introduction to this new edition, Bruce Levine provides a historical analysis of the debate over Time on the Cross. Levine reminds us of the continuing influence of the latter book, demonstrated by Robert W. Fogel's 1993 Nobel Prize in Economic Sciences, and hence the importance and timeliness of Gutman's critique.
