2/5 Does anyone with expertise in this area know why charged particles in plasma from #solar #flares, #coronal #mass ejections (#CMEs) and even #localized #thermonuclear #bursts, i.e. #micronovae, were not considered in this report?

The critique is fundamental & sounds persuasive. @m_clem criticizes:
1) using annual data gives too much weight to bursts & busts
2) time fixed effects mask long-term econ. progress
3) the empirical setup with absolute emigration, GDP & population leads to spurious results
