Number 3 exhibits the over simplification that I claim misses something important. Number 3 leads you down the path of thinking that society can only get more wealth by more transformation. Nothing in 3 allows for creating wealth by swappin

I think it is missing something foundational. People have preferences over both production and consumption. Perhaps Mr A likes to consume X, but hates the work involved in producing X. Meanwhile Mr B likes to consume Y but hates the work in

I agree that we should be tracking years of lost life expectancy. I also believe in attempting a quality adjustment; we get better public policy from counting Quality Adjusted Life Years (QALY) lost. I think that the main obstacle to this a

When it comes to momentous public policy decisions, such as closing down much of the economy, or shutting schools, it is important to use the right metric. Counting deaths often works. If deaths are evenly spread across age and health, so t

We've been here before, with stars older than the age of the universe. Last time, we thought that there was only one kind of Cepheid variable. This lead to underestimating the age of the universe. Later, astronomers realized the nearby
