Looking for a paper on game theory as a beautiful thing, not needing immediate purpose

I am looking for a paper I am sure to have read a while ago, but cannot recall its title. The message was that we should not judge game theory (or economic theory in general?) by its ability as an "applied science", improving our understanding of…

Repeated games without a beginning and an end

I'm interested to know results on repeated games indexing each stage game by $\mathbb Z$ which contrast with those indexed by $\mathbb Z_+$. It seems to me this could be quite different from repeated games with a starting stage, because there's no…

Have there been attempts to estimate the costs of obesity?

I have two groups. One is 1.6 to 2.1 times more likely to be obese than the other group. I've also compared the body mass index and found that the group of people in question have higher body mass indexes. This would be expected based on previous…

Why do some game theory textbooks explicitly require preference relations to be reflexive?

A binary relation on a set of outcomes is called a preference relation if it is complete and transitive. Completeness of course implies reflexivity. But the authors of some game theory textbooks add reflexivity as an additional condition in their…

How do I change the base year of real GDP using the GDP deflator and nominal GDP?

I'll use the US as an example. I have three data series nominal GDP $(Y)$ real GDP in 2005 USD $(\bar{Y})$ the GDP deflator $(d)$, with 2005 as the base year, so $d_{2005} = 100$ I want to change the base year to 2000. Are these calculations…
