英文摘要：
  We study the effects of introducing information inefficiency in a model for a random linear economy with a representative consumer. This is done by considering statistical, instead of classical, economic general equilibria. Employing two different approaches we show that inefficiency increases the consumption set of a consumer but decreases her expected utility. In this scenario economic activity grows while welfare shrinks, that is the opposite of the behavior obtained by considering a rational consumer.

中文摘要：
我们研究了在具有代表性消费者的随机线性经济模型中引入信息无效率的影响。这是通过考虑统计而非经典的经济一般均衡来实现的。采用两种不同的方法，我们表明，低效率增加了消费者的消费集合，但降低了消费者的预期效用。在这种情况下，经济活动增长而福利收缩，这与理性消费者的行为相反。
