Which sector of a mixed economy is set up by the State mainly for the welfare of the community rather than for profit?

1. A mixed economy has private, public and combined sectors. 2. The private sector runs on profit motive and the combined sector is a joint venture. 3. The public sector is established by the State and is not primarily profit-oriented but welfare-oriented. 4. Hence the welfare-driven, non-profit sector is the public sector; the household sector is not one of the three industry sectors named. _Source: ICAI BoS CA Foundation Paper 4 Business Economics, Ch 1 Unit II "Basic Problems of an Economy and Role of Price Mechanism", p.7_
