1. I consider David Beckworth and Scott Sumner to be "mentors" in how I think about macroeconomics, particularly monetary policy. Team NGDP level target, FTW. Beckworth, who is on faculty at Western Kentucky, now has a new Macro Musing podcast hosted by Mercatus (George Mason Univ.) and his first interview is with Scott Sumner. If you want to know my economic worldview, listen to this podcast.
2. Tim Keller is also a "mentor" in my Christian faith. He's one of the best authors and proponents of a proper theology of work out there. If you want to know what I believe about the role of a Christian in fulfilling the cultural mandate and why I reject the "If you were really sold out for Jesus you'd enter full-time vocational ministry" criticism as bad theology, I encourage you to listen to this sermon-- let him convince you. On Faith and Work (from his RISE series).
3. Andrew Wilson is a "writer and elder at King's Church in Eastbourne, England" who I was unfamiliar with before hearing him interviewed on The Village Church's podcast. He recently published a book with his wife about dealing with the surprise ups and downs of having two autistic children. He gets to that in the second half of the interview and it's quite good. Listen and enjoy. I will soon own his book.
