The paper presents a medium-run growth model driven by autonomous demand, where aggregate demand and supply interact and unemployment is present and plays different roles. In particular, it generates a feedback from supply to aggregate demand rooted in the presence of heterogeneous consumers and an uncertain environment. Two are the main consequences of this approach. The first is that multiple equilibria can be generated. The second is that equilibria may have different stability properties. In this perspective, growth becomes a dynamic process where initial conditions matter and history plays an important role.

自主需求、多重均衡和失业动态

本文提出了一个由自主需求驱动的中期增长模型，其中总需求和供给相互作用，失业存在并扮演不同的角色。特别是，它产生了从供应到总需求的反馈，这种反馈植根于异类消费者的存在和不确定的环境。两个是这种方法的主要后果。首先是可以产生多重均衡。第二个是平衡可能具有不同的稳定性属性。从这个角度来看，增长成为一个动态过程，其中初始条件很重要，历史起着重要作用。
