When Nurses Travel: Labor Supply Responses to Peak Demand for Nurses
研究在COVID-19疫情高峰期间，美国医院如何通过旅行护士市场应对突发的护理需求，发现劳动力供给弹性较大，且工资上涨会促使护士前往更远的地方工作。
Abstract We study how a market uses temporary workers to accommodate extraordinary demand shocks. When COVID-19 surges, hospitals need additional nurses—especially in specialties central to COVID-19 care. By comparing markets for COVID-relevant and other specialties, we show that the market for travel nurses expands dramatically and estimate travel nurse labor supply across space. Supply is quite elastic, as workers can choose to travel where they are needed. Workers travel longer distances to temporary jobs when payment increases, suggesting that an integrated national market facilitates reallocation when demand spikes. But when national cases peak, travel distance is less responsive to local demand.
