Visiting Association Professor, University Minnesota, 1978-1979. Association Professor Agriculture Economics, Hebrew University, Rehovot, Israel.
My main interest has been the economics of technical change. I started by studying the diffusion of innovations in agriculture and developed the notion of an innovation cycle — from the better to the less skilled farmer. Later I worked (with R.
Evenson) on the economics of agricultural research, both theoretically and empirically.
My latest interest has been in the changing structure of the farm as a result of technical progress.
Also interested in inflation and balance of payment questions, I have attempted to apply the monetary approach to the balance of payments to Israel’s experience.
