Essays / Deductive vs Inductive in a critique essay [3]

I am really confused... I have to write a critique essay, I am not sure if the article is using inductive or deductive reasoning. Basically it is about how a free market society brings about dislocation, which correlates with and causes addiction. The author gives a definition of free markets, tells how he thinks they correlate then gives 2 examples where we see dislocation and addiction.

Also what do I need to have in my intro paragraph for my essay? Should I have my thesis, a summary of the authors article and that's it? Or do I have to list everything I will be talking about.

Thanks
