This week’s guest is Dr. Jason Miller, Professor and Head of the Supply Chain Management Department at Michigan State University's Eli Broad College of Business.  This is Jason’s 4th time on the Freightvine podcast -  we last had him on the podcast about two years ago when we were one year into what is now called the rate trough.  Jason discusses this and how the market was expected to have rebounded by now, but the spate of tariffs has definitely had an impact.   In our conversation we discuss tariffs both conceptually and in practice.  We also look back at the past several truckload business cycles and discuss what the next cycle might look like.
