It’s Wednesday and so some short discussion and news then some jazz, the latter being the highlight. I read an interesting research paper yesterday from the – Conseil d’Analyse Économique (CAE) – which is an French-based organisation that brings together professional researchers “to enlighten the government’s choices in economic matters by comparing points of view and analyses”. It operates under the authority of the French Prime Minister. Its latest public report under its – Focus – series – The effect of COVID certificates on vaccine uptake, health outcomes, and the economy (published January 18, 2022) – presents some very interesting empirical results pertaining to the impact that the enforcement of Covid vaccination certificates has had on the rate of vaccination uptake, on health outcomes (short-term) and on GDP growth rates. I consider the research (methods etc) to be credible and the results are in accord with an array of evidence that other researchers are coming up with.
