comment Vector spaces as free algebras
I agree that this works, but wouldn't it also work for e.g. $X =\emptyset $? How am I supposed to know from the question what $X$ should be? Is $X$ supposed to be the free generators of $R$?

How do you define "inverse"?

comment Using risk aversion
It seems to me that in the paper cited in table 5 they have a hardcoded value (which they denote $\gamma $) which they plug into equation (10). Are you saying that I am misunderstanding what they did, or that what they did is wrong?

Thanks – I added a link to the paper I am actually trying to understand, which does have hardcoded values for this coefficient (I believe). Let me know if I misunderstanding this as well!
