Comparative advantage is an economic law referring to the ability of any given economic actor to produce goods and services at a lower opportunity cost than other economic actors.

Hard to say. I used to use this structure as my bible but I felt some of the comparisons I was getting back were very simplistic. Basically some students were only pointing out obvious similarities but failing to comment on subtle differences between the texts. As long as you bear in mind that subtle differences matter every bit as much as similarities, you should be fine to use this structure. This example might also help (it’s cultural context rather than theme but the same basic principles apply) http:///2013/12/sample-comparative-link/
