在存在调整成本的情况下加快COVID-19疫苗生产的激励措施
Incentives for accelerating the production of Covid-19 vaccines in the presence of adjustment costs
摘要：
随着大流行病的持续，疫苗供应的延误代价高昂。然而，在存在调整成本的情况下，企业只有逐步增加生产能力的动机。现有的合同只规定了在一定时期内供应的固定数量，因此没有为加速建立生产能力提供任何激励。高价并不能改变这一点。最优合同将指定一个随时间递减的价格表，它可以复制社会最优。
英文摘要：
Delays in the availability of vaccines are costly as the pandemic continues. However, in the presence of adjustment costs firms have an incentive to increase production capacity only gradually. The existing contracts specify only a fixed quantity to be supplied over a certain period and thus provide no incentive for an accelerated buildup in capacity. A high price does not change this. The optimal contract would specify a decreasing price schedule over time which can replicate the social optimum.
