- [[collective action problem]], [[exploit-explore tradeoff]], [[promote cooperation]] # Idea There is a pool of limited but self-replenishing resources. If collectively, we consume and deplete it too quickly, it won't replenish quickly enough. Let $x_j$ be the the amount consumed by $j$. $X$ is the total amount consumed. Amount available next period: $C_{t+1}=\left(C_{t}-X\right)^{2}$ If $C_1 = 25$ and $X_1 = 20$, we get [[equilibrium]]. But if $X_1$ increases to 21, we deplete $C$. # References - [[White 1967 historical roots of our ecologic crisis]] - [[Diamond 2004 collapse]]
