The author argues that the concept of the public good carries largely the politico-ethical sense which subsumes the politico-economic sense. The public good is public in the sense that the beneficiaries are the general public. The government or state pursues it with a service orientation while private corporations pursue it with a profit orientation. The author also discusses mixed public goods which are pursued by private organizations with a service motivation. Government corporations are basically motivated by service though having profit is not precluded. Finally, the author talks about public bads such as corruption, pollution, and crimes.
