How is this calculated

On page 128 there is a table showing how much 'life misery' can be reduced by eliminating different issues - such as poverty and mental illness. But I can't get my head around the coefficients ( why is it an α-coefficient ? ).

I'm no expert in statistics and the answers might be really simple.
I would really appreciate if someone could explain this to me as I'm considering using it in an assignment (Im studying social science, not statistics)

Thank you

So different fields, I thought social sciences, use alpha to represent model coefficients instead of betas. Without reading the document in detail, I think it is probably safe to just interpret alphas the same as you would interpret betas.

This is given you are familiar with regression and coefficients. It looks like on the prior page they may present the model, see below. Looks just like any other regression model except the use of alphas instead of betas.

Is miserable (1,0) = a1 Is poor (1,0) +a2, ...
