Abstract
New
flexible-form and semi-parametric autoregressive non-linear count models for panel
data are developed to analyse the spread and containment of the COVID-19
pandemic. The models are based on a discrete time form of the SIR model. These
methods lead naturally to estimators of the infection process and daily
reproduction numbers by jurisdiction. Two semi-parametric versions of the
reproduction numbers are developed corresponding to currently popular
parametric estimators. The estimators are applied to a large international data
set to estimate these parameters for 221 jurisdictions at both national and
subnational levels.
JEL classification numbers: C14, C23,
