SAVINGS AND PREDATION
对比两种简单模型中掠夺与潜在受害者储蓄的关系：外生掠夺下储蓄随掠夺概率上升而下降；内生掠夺下掠夺概率可能与储蓄正相关，且对储蓄和效用的损害更大。
We contrast the relationship between predation and the savings of its potential victim in two different simple models. In the first model, predation is an exogenous event in which savings are expropriated with some fixed probability. In such a setting, the higher the probability of expropriation the lower are savings. In the second model, we endow the predatory agent with a decision whether to expropriate or to devote his efforts to some productive endeavor. In this second model, the (endogenous) probability of expropriation can easily be positively correlated with savings. In addition, we show that predation is more damaging to the savings and utility of the victim in the second model.
