Dp. Deboer et L. Evans, THE ECONOMIC-EFFICIENCY OF TELECOMMUNICATIONS IN A DEREGULATED MARKET- THE CASE OF NEW-ZEALAND, Economic record, 72(216), 1996, pp. 24-35
This paper estimates the productivity and consumer and producer change
s in the New Zealand telecommunications network market between 1987, w
hen it was deregulated, and 1993; as the major firm, Telecom, evolved
from a government department to a public company in an environment of
light regulation. The growth in productivity is estimated to reduced c
osts at an annual compound average of 5.6 per cent. The bulk of the su
bstantial gains in consumer surplus has come from price reductions on
1987 consumption levels. There has been marked improvements in the qua
lity of outputs. Shareholders have had a profitable investment.
