Career reset? Our MS programs allow students from any academic background to earn a STEM-designated degree @TuftsUniversity for impactful work in #agriculture, #nutrition & #health. Intro classes like my #FoodEconomics lead to high-value specializations nutrition.tufts.edu/academics/degr…

This talk on Food Prices for Nutrition is my best effort at a quick and entertaining summary of how & why @FAOstatistics, @worldbankdata, @NBS_Nigeria and others measure the Cost and Affordability of Healthy Diets, and what results imply for food choices youtube.com/watch?v=InEuX8…

📢Attention policy people out there! 👉Join @FAO next Tuesday, 10 February 2026 at 3pm (CET/Rome time) as we take a major new step in scaling up country support to monitor – and hopefully lower – the Cost & Affordability of a Healthy Diet (CoAHD) at the national level. 🔗Register here➡️: fao.zoom.us/webinar/regist… 👀See the flyer online: openknowledge.fao.org/handle/20.500.… #CoAHD

#NEUDC2025 is at @TuftsEconomics this Nov 8–9 🎓 Two days of cutting-edge work on development, climate, health & policy and more — with researchers from around the world 🌏 Registration closes Oct 17 → neudc2025.com #Economics #Research #Tufts #NEUDC #publicpolicy

Thanks to Pablo Rosado of @OurWorldInData for a clear, vivid explanation of what #FoodPricesForNutrition metrics reveal about healthy diet costs and affordability. The best visualizations of results through 2024: ourworldindata.org/diet-affordabi…

Just posted, a brief & clear memo from @EconoFactOrg by @dwschanz on why the @USDA food security questionnaire is needed. The government's statement about why they plan to stop data collection is even shorter: usda.gov/about-usda/new… but this is better: econofact.org/what-would-we-…

Big new paper in @AJCNutrition shows limits to the common belief that healthy & sustainable foods are more expensive than other options. Details: linkedin.com/posts/wamaster… Article: doi.org/10.1016/j.ajcn… Preprint: sites.tufts.edu/foodpricesforn… #econtwitter

For university courses about #FoodEconomics, a full set of class slides, exercises & exams is now available for use with our free online textbook, serving advanced undergrads and first-year grad students using diagrams, examples and global data. Info here: sites.tufts.edu/foodeconomics

This year's #AAEA2025 coincides with launch of the UN system's #SOFI2025 report on The State of Food Security and Nutrition in the World. Beyond diet costs and affordability, this year's data includes new work on relative cost of nutritional food groups #gsc.tab=0" target="_blank" rel="nofollow noopener">openknowledge.fao.org/server/api/cor…

This week's launch of #SOFI2025 marks the 4th annual update of global diet cost and affordability data, used by UN agencies and national governments as a clear and actionable new metric of global food security.

I am speaking at 2025 AAEA & WAEA Joint Annual Meeting. Please check out my talk if you're attending the event! #AAEA2025

@DaveEvansPhD Thanks to @DaveEvansPhD of @CGDev for brilliant live-posting of #ABCDE2025 talks... and now hosting the closing discussion with @MamtaMurthi of @WorldBank. Follow his posts for many great points presented over the past 4 days

Will Masters (@WAMasters) of Tufts University shows how a well-crafted indicator (in this case, the lowest cost of a healthy diet) can actively inform civil society discussion. For more, read his paper sciencedirect.com/science/articl… #ABCDE2025

July 25, 9 AM ET ➡️ Join @CGDev & @wb_research for an #ABCDE2025 panel on agricultural markets and nutrition. 📆 With: @cbb2cornell, @wamasters, @KibromTafere, Kathy Baylis, and Eeshani Kandpal. Register: link.cgdev.org/l/683263/2025-…

Latest on #FoodPricesForNutrition, a review article for the 50th anniversary of @_Food_Policy on rapid adoption since 2020 of least-cost diets for monitoring food access, globally by @FAO & @WorldBank or in countries by @NBS_Nigeria, @EPHIEthiopia etc.: authors.elsevier.com/a/1lND015oGpOO…

@cpgrabow Weirdly the bill says it applies only to cargo "procured, furnished, or financed by the Dept of Transportation", which as far as I can is basically zero because DOT doesn't do that. Is this bill just theater, or will they expand from DOT to other agencies?

Protectionism is all about dispersed costs and CONCENTRATED BENEFITS 👇

Such a great resource for ag /nutrition /food educators and students of any age! Just wrapped a wonderful #sustainwhat conversation on food realities and futures with globe-spanning food photographer @georgesteinmetz , @wamasters and @ameliafinaret! Link in reply. Here's an intro moment with George.

What can we learn from food economics? Last month on VoxDev, @wamasters @tuftsnutrition & @ameliafinaret @alleghenycol spoke to @timsvengali about their new, open access textbook on Food Economics and what we can learn from the subject: voxdev.org/topic/agricult…

Our new #Fellowships from @ANH_Academy offer a year of funding to bring recent #research into #policy decisions in #SubSaharanAfrica or #SouthAsia, via placement in a policy-making organization. Aim is healthier diets, less loss & waste + climate & equity. anh-academy.org/science-policy…
