Today has been quite the day. It is just mid-afternoon, and, in addition to a Kyiv School of Economics Board of Directors meeting on Zoom on various important issues, I managed, as of now, to do 4 interviews with the media on Trump, tariffs, and trade, because (we will see if this comes to pass), as of midnight tonight, Trump is to impose 25% tariffs on products from our neighbor Canada and 10% tariffs on products from China. The tariffs on Mexican products have been "paused" for 30 days, due to an agreement between the two Presidents. The situation is incredibly dynamic and volatile.
When I agree to interview requests, it is on topics that are not only timely but ones that we have conducted research on. I remember fondly when we began to write on the impacts of tariffs (and there are several types, I might add). Colleagues, who were then at Cornell University, Charles F. Nicholson and Phillip M Bishop, were working on impacts of ad valorem tariffs on dairy products from Mexico, had reached out to me and then visited me at the University of Massachusetts Amherst. We published a series of papers, including one in the Annals of Operations Research. Since then, collaborations (and publications) have continued, many with a focus on agricultural products and the impacts of trade policies. Thanks to my co-authors: Dana Hassani, Oleg Nivievskyi, Pavel Martyshev, Deniz Besik, PhD, Michelle Li, June Dong, Ladimer Nagurney, and Mojtaba Salarpour for research that continues to resonate, with acknowledgment to journals, including: the Journal of Global Optimization, the European Journal of Operational Research, Transportation Research E, and the International Transactions in Operational Research, that have published our work on tariffs and other policy instruments (such as quotas and subsidies) and their impacts on commodity flows, producer and consumer prices, and consumer welfare!

Below is a collage of first pages of several of our papers on tariffs.
