This study provides empirical evidence on the relationship between pri
ce protection and productivity growth. From theoretical considerations
, it is concluded that the impact of price protection on productivity
growth is ambiguous. Although protectionism may in some instances stim
ulate investment and adoption of new technologies, efficiency may decr
ease, particularly when farm prices and income are high. Empirical evi
dence from the New Zealand beef/sheep industry indicates that high pro
tection during the 1975-85 period produced negative productivity growt
h. Following market liberalization in 1985, productivity growth increa
sed substantially.
