FIGHTING TRANSIENT EPIDEMICS—OPTIMAL VACCINATION SCHEDULES BEFORE AND AFTER AN OUTBREAK
研究了在疾病通常自愈的短暂流行病中，疫情爆发前后如何安排疫苗接种计划，发现疫苗接种可能存在规模报酬递增效应。
Epidemic diseases afflict all countries, and all epidemics are costly to society. The present paper examines optimal vaccination trajectories before and after an outbreak of a special class of epidemics where the disease normally eradicates itself. The focus is on epidemics where mortality may be ignored, influenza being the prime example. One important insight is that there may be increasing returns to scale in vaccination.
