Kind of busy tonight, so I will just step in for a minute or two.
re public vs. private firms:
Econ literature, primarily in the US, shows that public firms usually have higher operating costs than similar private firms. Studies include electricity, water, hospitals, refuse collection, railroads, airlines, and weather forecasting. There's a good summary in Viscusi, Vernon, and Harrington, Economics of Regulation and Antitrust, 2ed, cpt. 14.
re NZ airlines:
If there is only room for one airline (natural monopoly), cost effects are such that it is probably more efficient to regulate it rather than have it publicly owned. Public ownership provides fewer constraints on cost than admittedly imperfect regulations.
Also, probably the most convincing study of costs of private vs. public firms is David Davies, "Property Rights and Economic Efficiency: The Australian Airline Revisited", Journal of Law and Economics April 1977. Davies compared two Australian airlines, Ansett (private) and Trans Australian (public), which were nearly identical in terms of route structure, freight, passengers, revenue, etc. He found that Ansett's costs were half those of Trans Australian for the same service.
re political motivations of public firms:
One particularly disasterous recent case was the Bonneville Power Administration, a public firm which produces hydroelectric power in the Pacific Northwest. At the height of the California power crisis, Bonneville refused to sell power into California because they understood their political mission to be providing low cost electricity to consumers in the Pacific Northwest. A profit-oriented firm would have sold power into California, increasing PNW prices a bit, but reducing California prices dramatically.
I will be at an economics conference most of this week, so I won't be around much.
edit: spelling
