The results also show that input scores have not changed that much for most countries. This is because
the lowest spending country, Thailand, also has a PSP score higher than most sample countries. Hence
for these countries, input efficiency did not change. Only those with higher performance are now
assessed relative to the other countries on the production possibility frontier and post a higher input
efficiency score. The average increased from 0.55 to 0.59. As regards output efficiency, changes are
more substantial if the reference point for countries with large public sectors is not any more Singapore
but Cyprus, Ireland and Korea. The average increased from 0.67 to 0.78.
