Belief-driven dynamics in a behavioral SEIRD macroeconomic model with sceptics
研究在COVID-19疫情期间，部分人群对社交距离和疫苗的怀疑态度如何通过有限理性认知影响流行病动态，并削弱封锁等公共健康政策的长期效果。
The reluctance of a non-trivial fraction of the population to adhere to social distancing measures – and even to get vaccinated – during the COVID-19 pandemic represented a challenge for imposed public health policies in many countries around the world. Against this background we study the impact of boundedly rational perceptions for the dynamics of epidemics such as the COVID-19 pandemic in a standard epidemic model extended by a stylized macroeconomic dimension similar to Atkeson et al. (2021) . We illustrate through which channels misperceptions or even “scepticism” concerning the infectiousness of the disease or its mortality rate may undermine the effectiveness of lockdowns and other public health policies in the long-run.
