Delighted that Our Paper on Fresh Produce Trade and "Choke Points" is Published in EJOR!

The three of us worked very hard on this paper, "Fresh Produce Spatial Price Equilibrium on General Networks: Capturing Commodity Quality Deterioration Through Endogenous Transportation Time Delay Functions with Capacities," and it took three revisions (a record for me, I must say) before acceptance. My co-authors on this paper are Samirasadat "Samira" Samadi, who is one of my PhD students, and Professor Deniz Besik of the Robins School of Business at the University of Richmond.

The paper was published in a volume of the European Journal of Operational Research (EJOR) this past week, which was extra exciting since it also was the last week of classes of the academic year at UMass Amherst!

The link to the journal publication of the article is here: https://www.sciencedirect.com/science/article/abs/pii/S0377221726003759.

The work was inspired by many challenges associated with fresh produce transportation and quality of the commodities because of issues such as drought as in the Panama Canal and now the essential shutdown of the Strait of Hormuz because of the war on Iran. We capture endogeneous transportation delays due to capacity reduction on links and the impact on quality of fresh produce as it travels from supply markets to demand markets. The case study in the paper is on the global trade of bananas, a nutritious and very popular fruit, which is also important for food security. We also propose commodity quality trade network performance measures, supply-based, demand-based, and network-based, that can be applied for an individual commodity or across all commodities.

We are grateful to the EJOR Editor, Professor Mike Yearworth, who handled out paper, and to the reviewers for their comments and suggestions. My co-authors and I very much believe in the relevance and importance of the research that resulted in this paper.

Our Latest Paper on Multicommodity Trade of Fresh Produce with a Case Study on Bananas Is Now Published!

I am thrilled that the paper, "Multicommodity Fresh Produce Trade Networks with Quality Deterioration Under Congestion and Transportation Capacities," that I co-authored with Deniz Besik of the University of Richmond is now published in the Journal of Global Optimization! Plus, the paper is published open access and can be read and downloaded on the link: https://link.springer.com/article/10.1007/s10898-025-01507-3.

Deniz presented this paper last year at the EURO Conference in Copenhagen:


The paper contains a very interesting case study on bananas, the most widely traded fruit globally, and demonstrates the impacts on fresh produce quality of transportation disruptions and delays. The work was inspired by recent challenges to transportation on the Panama Canal because of insufficient water, leading to congestion. The paper shows that because of negative transportation impacts, consumers may pay higher prices for bananas of lower quality. 

Deniz will present this paper at the 2025 Commodity and Energy Markets Association Annual Meeting (CEMA) in Houston in a few days, as I head to the EURO Conference in Leeds, United Kingdom, where I have three invited talks!

This was another outstanding collaboration of ours on a highly relevant topic.
