There is another common usage in which incentive is contrasted with coercion, as when economic moralists contrast incentive-driven work – such as entrepreneurship, employment, or volunteering motivated by remunerative, moral, or personal incentives – with coerced work – such as slavery or serfdom, where work is motivated by the threat or use of violence, pain and/or deprivation. In this usage, the category of "coercive incentives" is excluded. For the purposes of this article, however, "incentive" is used in the broader sense defined above.
