A social responsibility initiative gaining momentum is social entrepreneurship, the use of market-based methods to solve social problems. Social entrepreneurship is therefore an entrepreneurial approach to social problems such as homelessness, contaminated drinking water, damaged physical environments, and extreme poverty. A research-based model of social entrepreneurship emphasizes that compassion encourages social entrepreneurship. Compassion in the model is viewed as a prosocial motivation that connects the individual with a suffering community and triggers sensitivity to the needs of others.
