Remembering Andy Schmitz

I was very saddened to learn about the death of Andy Schmitz on October 8, 2026. Andy was a mentor, a colleague, and a friend, and I owe him a lot, both as a scholar and as a person. He was extremely important to me when I was a graduate student and a young faculty member. In many ways, he taught me the ropes about where and how to publish.

I knew about Andy before I came to Berkeley. When I was in Israel preparing to leave, Professor Asher Razin asked me why I was going to Berkeley when I had other opportunities. But then he added, “There is one guy there who is publishing all the time in journals. His name is Schmitz.” When I asked my friend Gershon Feder about the people there, he told me that the leading figures were Kuznets, de Janvry, and Schmitz. Kuznets was a fantastic teacher. De Janvry was in Chile when I arrived, and Schmitz was king of the coffee room.

Room 325 in Giannini Hall was our coffee room. During the year I arrived in the department (1973), some of the graduate students would play cards with some faculty members every day between 10 and 10:30. Others would sit in the room, talking and discussing economics with Andy.

Andy was a character. He had a farm in Saskatchewan, and his mood often depended on the weather on his farm. He would talk with everybody on every topic, and he made you feel like an equal. He used diagrams for his economic analysis, and he had incredible economic intuition and an ability to develop an analysis that addressed a practical situation.

Andy the mentor

I had received my undergraduate degree and taken some master’s-level classes at Tel Aviv University. My impression of economics was that it used very complex mathematical tools to prove common-sense propositions and develop very useful formulas and procedures for policymaking. I did not really understand the moral, ethical, and political importance of economic analysis until I met Andy.

Andy was a big believer in welfare economics. He argued that an efficient outcome was not enough. Whenever there was a change, it was very important to him to understand who gained, who lost, by how much, and what happened to the losers. Was there a way to compensate them?

He applied this approach to many problems. One of his most important papers—and, in my view, one of the top five papers ever produced in the department—was his paper on the tomato harvester, published in the American Journal of Agricultural Economics.[1] It was part of a huge controversy. The paper argued that the tomato harvester improved the overall economic well-being of California, but the gains went mostly to farmers and consumers, while the big losers were farmworkers. This paper was very important in the fight to develop mechanisms to compensate farmworkers who lost their jobs because of new technology, and to create institutions that could help them. The impact of the debate surrounding this paper continues to this day.

Another thing I learned from Andy was the importance of market structure. Andy was a trade theorist, and he taught me that, when it comes to trade and markets, the competitive model is a nice metaphor and a great benchmark, but it does not always reflect reality. Markets have several levels, and we need to understand the relationships between them. Is there a monopoly? Is there a monopsony? In many cases, there is a middleman. A middleman is a company that may have monopoly power toward its customers and monopsony power toward its suppliers. Apple, for example, has unique products, and it makes a lot of money because it can exercise market power on both sides, in its dealings with suppliers and consumers.

When you worked with Andy and raised a problem, the discussion often led to a journal article. At the time, in the early 1970s, we lived in an era of price controls aimed at protecting consumers. Andy pointed out that much of the analysis behind these policies assumed that there were three main players in the economy—producers of food and other products, consumers, and the government—and ignored intermediaries. One paper resulting from this insight appeared in the American Economic Review[2]. We developed a formula to calculate the errors resulting from price-support policies that ignore middlemen and derived alternative policies that take their existence into account. Another “coffee room” paper appeared in Science magazine in 1979[3]. It was written in response to suggestions to slow technological change in order to preserve workers’ income, especially in agriculture. We suggested interventions that would capture the net benefits of technological progress without harming workers—such as worker retraining and severance compensation programs—rather than halting technological growth.

A scholar who helped build the department

As Alain de Janvry noted in his heartfelt tribute to Andy, Andy always emphasized that being agricultural economists does not prevent us from publishing in top economics journals. The opposite is true: we are exposed to real-world problems, and we can use them to develop sophisticated models that can enrich the mainstream economic literature. We should have a balanced portfolio: papers in mainstream journals like the American Economic Review and Econometrica, papers in agricultural economics journals, and papers in journals like Science. He practiced what he taught. In the 1980s, he published fifteen papers with students and other collaborators in top mainstream economics journals, in addition to numerous papers in agricultural economics journals. These papers offered theoretical insights and useful lessons, even though they might not have been the most complex. Andy also influenced the research methods of applied economists through his practical, classic book on applied welfare economics[4], coauthored with his students Richard Just and Darrell Hueth.

Andy’s leadership and academic achievements were very important in the early 1970s, when the department was on the brink of closure. Andy actively supported our chair, Jim Bowles, in getting new positions and recruiting Richard Just, whose arrival was a turning point for the department. I remember Andy’s excitement about the hiring of Michael Hanemann and Irma Adelman. He told us that, with these additions, we were climbing to the top of environmental and development economics. Andy was one of the few representatives of the department at the AAEA meetings in the 1970s, and in 1985 he became the department’s first AAEA Fellow since I had joined the faculty. Andy was also among the effort to bring a senior Ag Economist to Chair the department in the late 70s to push it to the top, an effort that led to the selection of Gordon Rausser as Chair and a lasting period of eminence of the department. 

Andy was chairman of the department from 1989 to 1993. During that period, California voters considered Big Green, a proposition to phase out the use of pesticides on crops. Drawing on research we had done, mostly for the EPA, we organized a conference on the topic. We argued that pesticides needed to be regulated, but a blanket ban did not make sense: our research suggested that the social benefits of appropriately managed pesticide use could substantially exceed the costs. We faced considerable political pressure against this effort, and Andy stood firmly behind me. He was strong in defending me and my right to present the research. Later, a paper based on our work on pesticides appeared in Science magazine[5].

Long lasting career and friendships

Andy left the department as part of an early retirement program and moved to the University of Florida in 1994. In Florida, he continued to be an active researcher and mentored a lot of younger economists, in particular Chuck Moss, Krishna Kramer, and his son, Troy Schmitz, to produce several edited volumes and papers. He kept his knack for addressing emerging, controversial problems. He and his co-authors applied a public choice theory and political economy models to explain how lobby groups shape tariffs, subsidies, and farm policy to produce a book on agricultural policy, Agribusiness, and Rent-Seeking Behavior[6]. He continued to develop elegant models to explain and quantify how government compensate strong interest groups in order to modify federal program (elimination of the tobacco and peanut programs)[7].  About 15 years ago, he led the writing of a book on an emerging topic at the time, The Economics of Alternative Energy Sources and Globalization[8].  

Andy and Carole were always a warm and friendly couple. Their home was a place where faculty and students mingled. You could spend time there relaxing with distinguished professors like Irma Adelman and with students who had just arrived. We would have a good dinner, the wine would flow, and we would talk and sing. Andy had a great voice, and Carol was a good pianist, and everyone had a good time. Andy was very perceptive, and during periods of stress in our lives, including during my divorce, he made sure to invite us to dinner or festivities in his home. Their house also hosted departmental parties and other events, and our children grew up with the department. For many of us, including me as a first-year student, it felt like a second home.

Over the years, we shared many experiences. I visited Andy’s home village in Saskatchewan, and we traveled together extensively around the world. Andy and I organized a conference in Costa Rica, where we had a great time exploring the tropical forest, traveling by boat through the jungle, enjoying the wildlife, and making friends.

I visited him several times after he moved to the University of Florida in Gainesville. Leorah and I stayed with Andy and Carole for a week and had a great trip together to St. Augustine and other places in Florida. Another visit coincided with the terrible day when Prime Minister Rabin was killed. Andy and Carol were extremely supportive during that very difficult moment for me. On another occasion, I gave a seminar and went on a fishing trip with Andy and his faculty colleagues. In 1999, we co-organized a conference in Gainesville on climate change. It was extremely well attended, and Florida officials expressed a great deal of concern about climate change because they worried that parts of the Everglades would be lost. I always loved meeting Andy at AEA conferences. Even two years ago, he showed me on a napkin a nice, clever theoretical result that he was able to draw geometrically, and we spoke about papers and collaboration. He was a real scholar to the end. He really loved economics. He loved people. He loved his family, and we will all miss him.

Andy’s friends and colleagues recognize his contributions and he has an appreciation club in the AAEA. His excellence was also recognized at the University of Florida by citation at the University of Florida.

  2. Andy was one of a kind. He and his family have always been gracious and a joy to be around. Our professional career was greatly enhanced by our collaborations with Andy. His energy and true love of economics and agriculture were unmatched. We are charmed to have called Andy and to consider Carole, Troy and the rest of the clan as our friends. Andy will be missed but never forgotten by those who knew him.

    Andy was a great colleague and a big help to we juniors in the profession. So memorable were the many IATRC gatherings and especially gathering around the piano with Carole and Andy to sing and be joyful. From serious professional collaborations like books and conference events, including the most memorable Moose Jaw conferences, to AAEA and IATRC, to book collaborations, to enjoyment of life, he lived life to the fullest and inspired all of us.

    Thanks to David for the thoughtful essay on the importance of Professor Andrew “Andy” Schmitz who also had an extraordinary influence on my professional life.

    I can reinforce David’s admiration for Andy’s 1) concern for fairness, 2) respect for Welfare Economics, 3) reality in assumptions about market forces, 4) the importance of graphics in communication of economics, and 5) the power of economics to improve labor and natural resource management.

    I also completely agree with David that an agricultural economist (or natural resource economist in my case) has an advantage working to resolve real-world problems, and we can use that reality to develop sophisticated models that can enrich the mainstream economic literature. For me the value added was also knowing that assumptions in sophisticated economic models can be manipulated to yield results to mislead policy or to simply overwhelm simple truth and common sense.

    Andy changed my life for the better when in 1974 he invited me to co-author a paper to assess the climatic, biological, and socioeconomic effects on northern latitude wheat production of a proposed fleet of supersonic transport (SST) aircraft operating in the stratosphere.

    That $20 million dollar Department of Transportation Climatic Impact Assessment Program (CIAP) was inspired by the warnings of Professor Paul J. Crutzen (Max Planck Institute for Chemistry) and Professor Harold Johnston (UC Berkeley). Coincidentally, in 1974 Post-Doctoral Student Dr. Mario J. Molina and Professor F. Sherwood Rowland (UC Irvine) warned that chlorofluorocarbon (CFC) emissions would also deplete stratospheric ozone.

    Stratospheric ozone shields Earth from ultraviolet radiation that causes skin cancer and cataracts, suppresses the human immune system, damages agricultural crops and natural ecosystems, diminishes aquatic and terrestrial carbon sinks, and deteriorates the built environment. In 1995 Professors Crutzen, Molina, and Rowland earned the 1995 Nobel Prize in Chemistry for their groundbreaking work in atmospheric chemistry.

    As David noted, Andy grew up on a northern latitude farm in Saskatchewan Canada and was keen to make our analysis of SST impacts absolutely accurate and influential. The CIAP science assessment showed that high-altitude emissions could potentially deplete the ozone layer and that high-altitude emissions could cause aerosol cooling at northern latitudes, which Andy knew would shorten the frost-free, growing degree days (GGDs) with the consequence of abandonment of the most northern farmland and shift at lower latitudes from wheat to less profitable grain barley, oat, and rye species.

    Schmitz, Andrew, Stephen O. Andersen, Tyler Biggs, and Janet L. Andersen. 1975. Climatic Change and Agriculture: A Case Study on Wheat. In Economic and Social Measures of Biologic and Climatic Change. Climatic Impact Assessment Program (CIAP) Monograph 6. US Department of Transportation, DOT/TST-75-51, Washington, D.C. September.

    I believe this paper is among the most important of Andy’s lifelong contributions because it helped catalyze broader international science around stratospheric chemistry and CFCs and other ozone-depleting substances (ODSs) and because it put me on my employment path that in 1986 landed me a job at the United States Environmental Protection Agency where I helped design, justify, negotiate, and implement the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer (Montreal Protocol). The Montreal Protocol is the only United Nations Treaty on any topic universally ratified by all 198 countries, has halted worldwide production of almost 100 ozone depleting chemicals to put the ozone layer on the path to recovery by mid-century and in 2016 was amended to control ozone-safe hydrofluorocarbons (HFCs) once necessary to rapidly phase out ODSs but no longer needed because environmentally superior replacements to HFCs are available or soon to be available.

    Proof of Andy’s influence on my appreciation of graphics is from papers I co-authored that were a basis for the 2016 Kigali Amendment showing that that without the Montreal Protocol by about 2010 climate forcing from ODSs would be the carbon equivalent of carbon dioxide (CO2) from fossil fuel emissions and would have ended life on Earth.

    Like David I consider myself fortunate to have come under the influence of Andy Schmitz as a complement to the influence of professors Siegfried V. Ciriacy-Wantrup, Luther “Tim” Wallace, Richard Norgaard and amazing graduate students of Berkeley in the 1960s and 70s.

  5. Andy’s passing is indeed very sad news. He was always a breath of fresh air in our often staid ag econ settings. He was a first rate trade economist and didn’t hesitate to call out erroneous or incomplete arguments. Andy and I collaborated on an AJAE article on a new era of environmental management in agriculture. He pushed my thinking in creative ways. As David noted, his work on the tomato harvester was way out in front on the need to incorporate distributional (equity) effects in sound welfare analysis and policy. His scholarship, unbounded energy and good humor will be sorely missed. Sincere sympathies to the Schmitz family in your loss.

  6. Stefan Tangermann

    Willi Meyers has characterized Andy in a most accurate and fitting way. Andy was an absolutely unique combination of a top economist and a man who knew how to enjoy life – and let others benefit from both. IATRC meetings without Andy were unthinkable at the time, in both their professional sessions and the after dinner singing. Without Andy, the world no longer is what it used to be.
