The problems found in today’s society reflect the new needs of individuals and the new challenges to which they are exposed. Dias (2009) asserts that governments, the market and institutions of the third sector are not able to resolve the challenges of the twenty-first century, so other possibilities should be considered to minimize social disparities (high unemployment, urban poverty, social exclusion and all types of discrimination etc.). Organizations of the third sector are often influenced by a practice immersed in philanthropy and assistance. Demo (2002) criticizes this form of solidarity by pointing out that the intelligence of the beneficiaries is often denigrated. These entities at times are seen as inefficient, ineffective and bereft of responses. In contrast, social entrepreneurship comes, in principle, to respond to the new demands of society, by combining the passion for a social mission with the procedures of traditional economic activities, such as productivity, discipline, efficiency, innovation and determination to achieve results. Compare and contrast Social Entrepreneurship from Business Entrepreneurship and evaluate the impact of social entrepreneurship in national economic development by giving practical examples.
