1. with the simple thesis of consumers having

3. where the thesis was simple: consumers having
4. with a thesis that is a simple one: consumers have
5. whose thesis was simple: consumers have

Look at all the connectors
With: shows that some additional thesis was also published. Is this the case? No.
Which: would explain World. Is that required? no
where: ALWAYS point to some place noun. Is this the case? no

Whose: acts as the object. In our sentence also we try to explain on what thesis or on what fundamental was Shopping for a better world based on. This can be said as whose thesis was .... where whose refer to Shopping for a better world.

Also note to use of colon : Whatever is present after (Colon) should explain something about the thing that is present just before it. Also note whatever we write after colon is a general statement explaining the thesis. Therefore we should use present tense and hence we should use, HAVE

I hope this helps

Thanks
