Relative rate of assistance to agriculture, excluding decoupled payments, 1956 to 2004 (percent)
“The Relative Rate of Assistance is calculated as RRA = 100[(100+NRAag)/(100+NRAnonag) – 1], where NRAagt and NRAnonagt are the average percentage Nominal Rates of Assistance for the tradable parts of the agricultural and non-agricultural sectors, respectively.”
From: Kym Anderson and Tim Josling.
Australia and New Zealand have low relative rates of agricultural to non-agricultural protection because both had protection in manufacturing exceeding that in agriculture before they “unilaterally moved to virtually free markets in farm and non-farm goods.” European, Japanese and Korean protection is heavily concentrated in the agricultural sector. And America? It appears to protect its agricultural and non-agricultural sectors evenhandedly.
The shortcoming of the graph is that it depicts only relative protection. Visualizing both absolute and relative protection in the same figure would be very informative, though a bit difficult to construct.

Is it just my browser or are you graphs coming up a bit too small and, consequently, illegible.
They look okay on my browser. Click the link and scroll down a bit to see the original graph at full size.
I thought it might be my resolution (1920×1200) or browser settings (I still use IE), but changing those did not alleviate the problem. This has happened with previous posts. The picture above is coming out as 450×281 while the original is 768×480.
Are you resizing them?
Yea, I resize to fit the frame width. I’ve boosted it to 600 now.
