implement risky food simulation

[rlskoeser]

Game: risky food source is 3 if N, 1 if C; safe source is 2

(non-contaminated / contaminated)

Every agent gets a parameter r between 0 and 1.  [or DISCRETE: 8 buckets etc.]

EACH ROUND:
Nature selects a probability p for N
For each agent: if r > p, then they choose RISKY; else SAFE
Nature flips a coin with bias p for N, and announces N or C
If N: everyone who chose RISKY gets 3, everyone who chose SAFE gets 2
If C: everyone who chose RISKY gets 1, everyone SAFE 2
Reproduce in proportion to payoff
Either agent gets # of offspring = payoff [they replace–original “dies off”]
OR: take the total payoff for RISKYs over total for everyone, there are that proportion of RISKYs in the new population

END ROUND

SEE: We’ll see what are the risk attitudes that are replicated more and less over time
