One of my research agendas if I get an academic or WB job is to just hang out at a construction site in a developing country and keep track of these kinds of things to understand what hidden costs affect the construction sector in these places
I could do that in NYC, too, but I'm a dev economist.

There's *a lot* of room for empirical work on the role of the population boom in the east asian growth story. Most work is from the 1980s.

why has everyone suddenly started talking about fertility this year? I’m sure there wasn’t so much fertility talk last year. before this year only some people on the right talked about it. now it’s mainstreamed. I remain the only person not talking about fertility
