David Cass Passed Away

(Picture from U of Penn, department of economics)

I didn't know that David Cass, well-known economist for "Ramsey-Cass-Koopmans model", had recently passed away.

I told this model before as an optimal economic growth model, but it's a very casual explanation.

If you want to know about it more accurately, it would be much better for you to read David Romer, Advanced Macroeconomics, Chapter 2.
