I thought some of the analyses here[1] were interesting. The economic analysis wasn't the most compelling to me. What I thought was thought provoking was the ratio of months of lockdown to months of lives saved. IIRC it took something like 51 lockdown-months for each extra month of life saved due to COVID (although the math is a bit back-of-the-envelope)
