I really enjoy the interviews that the folks at the Institute for New Economic Thinking (INET) have been producing recently. They provide a quick and easy way of learning about new and different approaches to economics.
One interview that I think is particularly interesting from a policy standpoint is the one with economist Mario Seccareccia of the University of Ottawa. The topics discussed during the interview include the pre- and post-crisis approaches to fiscal and monetary policy, functional finance, the financial flows view of macromanagement, public capital budgeting and the productivity-enhancing role of public investment.
Needless to say, I believe the issues discussed in this interview are of fundamental importance to the modern practice of economic policymaking. The part of the interview that I found most interesting is when M. Seccareccia explains the importance of public investment, and the critical role it plays on enhancing productivity.
For those who are interested in knowing more about public capital budgeting, I recommend this excellent short paper by the late economist Richard Musgrave, a pillar in the area of public finance. R. Musgrave's ideas are discussed during the interview.
