It’s sad when friends die. One is left with sorrow and a sense of impotence.
Eduardo Ley passed away on July 1st.
I met Eduardo in 2004, when I moved to Washington to work at the IMF.
He was an excellent economist/econometrician, a very, very smart guy, very funny and goodharted.
After his PhD at Michigan (with Hal Varian), Eduardo taught at Carlos III in Spain and then moved to the IMF and then to the World Bank. He published a lot of  widely cited  papers, mainly on Public Finance, Welfare Economics, Applied
Microeconomics, Environmental Economics, Statistics, Econometrics,
Bayesian Methods, Bayesian econometrics and Taxation. I particularly like one of his citation from his blog

“I have no data yet.  It is a capital mistake to theorize before one has
data.  Insensibly one begins to twist facts to suit theories, instead of
theories to suit facts.”  -Sherlock Holmes in A Scandal in Bohemia by
Arthur Conan Doyle (1859-1930)

I will miss my friend and our furious ping-pong matches in the Fund basement.
