Exam-Utility Maximization

Introduction
though everyone keep asking how could i was still able to read comics during the final exam but i think i have my own theory here. and though (again) i haven't done any hypothesis testing to ensure this is valid, at least, it worked for me.

Literature review:
Leontief function of labor worked in Keynesian with sticky wages (Scarth, chapter 3, Classical and Keynesian Model) Nmin= Y1,Y2.


Theory:

U = min (S,C)

dU/dS > 0 ; dU/dC > 0

U'' (S) <>subject to 24 hours and leisure (other activities beside studying and comic-ing)


Economic Analysis:
well, i just assumed that during EXAM, utility is leontief function of studying and comic-ing. and the constraint for maximizing the utility is 24 hours per day and leisure time which is other activities beside learning.

i won't explain the maximization but i will explain how the mechanism is. utility is the combination of S and C. When I prefer S, it means the utility of S is very high but at one point it will diminish and the C will give me more utility.


Implication:
What I was doing in last exam was maximizing utility of comic-ing until it diminished and at that time i would need the utility from study-ing.


Empirical evidence and Critique:
The speed of diminishing marginal utility from comic-ing is way too slow--moreover, almost rigid, so it is not U'' (C) > 0 but U'' (C) is infinite. and the speed of diminishing marginal utility is way too fast.




Urrrrghhh. But still, effective then.
