On the policy relevance of agricultural economics

That’s the title of a new article by David Just released by the European Review of Agricultural Economics, and the subject of David’s keynote at the European Association of Agricultural Economics Meeting this week in France. He writes:

Throughout the early 2000s, many departments of agricultural economics reduced their faculty size and some prominent departments began to generalise their focus to cover applied economics broadly and/or diminish their emphasis on agriculture in particular. This was in response to what had been seen as a long and inevitable drift to the irrelevance of agricultural economics and the agricultural economy in developed nations. But a funny thing happened on the way to the dustbin of history. Highlighted by efforts such as the comprehensive report of the Scientific Group of the UN Food Systems Summit (von Braun et al., 2021) or the widely circulated Eat-Lancet report (Willett et al., 2019), suddenly agriculture finds itself as the keystone to solving myriad grand challenges facing the world; and agricultural economic analysis and tools are central to doing so effectively (Just, 2022).

Despite the rising importance and prominence of the work by agricultural economists, Just argues:

In each of these cases [price spikes circa 2008, trade wars, COVID-19 supply chain disruptions, and price spikes in the last two years], foundational and relatively straightforward agricultural economic analysis could have identified the growing vulnerability and threat to global stability and welfare. However, in each case, such analysis was not published, publicised or available until after the threat was realised. Having the analysis beforehand, and credibly argued before relevant policymakers, in each case could have led to mitigation or prevention of the crisis. This is a failure of our discipline and one that we should work to address.

He continues …

Agricultural economics has come to the fore as a key to addressing a confluence of global challenges. In addressing these challenges, agricultural economists are vital not only in advising on policies to directly impact the challenge goals but also in creating an atmosphere in which solutions are attainable and sustainable. In these three examples, one can see a pattern of crises that are at once economically significant and entirely predictable with rudimentary agricultural economic analysis. Yet, no credible agricultural economists were addressing these issues prior to crisis onset.

David’s article is well written, well reasoned, and an important encouragement to practicing agricultural economists. One need not agree with all of David’s claims to buy into the larger argument that timely economic analysis on food and agriculture issues are needed to improve public policy responses and reduce vulnerabilities.

There are a couple nuances to add. First I’m not sure that “no credible agricultural economists were addressing these issues prior to crisis onset.” It may very well be the case that there were not many peer reviewed journal articles published prior to these major events, but there were certainly economists writing on blogs and newsletters and being interviewed in media. Thus, I suspect the issue is not the lack of foresight by economists, but rather: 1) the institutional constraints on the types of economic research that is publishable in peer-reviewed journals of the sort Just cites, and 2) agricultural economists’ lack of influence in converting their ideas into main stream discourse. On the latter point, media and policy makers are often not very interested in crises that haven’t yet happened. Perhaps the bar is set high to avoid false positives, or it may simply just be that attention is scarce. I have published a number of articles and editorials in top media outlets, but I have had many, many more rejected.

Let me give a couple of examples from my own writing where I’ve projected an economic outcomes of interest of the sort Just describes. I use my posts as examples simply because I know them best, but there are many other examples from my colleagues as well.

The first is from March 16, 2020 at the onset of the COVID19 shutdowns. Even before any of the major meat packing plants had shutdown, it was clear given the concentrated nature of meat packing and the reliance on labor was a vulnerability. I wrote then:

Now, take a step back in the supply chain, and this is where worker issues could have serious issues. Remember all the fervor over the beef packing-plant fire back in August? While the impacts was counter-intuitive to many producers, the economics were straightforward: an unexpected disruption in supply depressed cattle prices and boosted wholesale beef prices. It isn’t far-fetched to imagine worker illnesses getting to the point that plants have to temporarily shut down on a scale that is at least as large as the August-fire, which removed about 5% of the nation’s beef processing capacity. One difference is that destroying a plant via fire is not the same as temporarily closing plants due to lack of healthy workers; one resulted in a long-term price adjustment while the latter is more likely a temporary price fluctuation.

One thing that makes me nervous even about temporary closures, if large scale, is the animals that have been placed to be market-weight in the next few weeks. While feedlot cattle can likely remain on feed a few weeks longer with relatively small changes in profitability, that is less true for hogs, and particularly chickens. Meat supply chains are optimized for efficiency and low-cost production, not necessarily for flexibility and resiliency.

It was only a few weeks later than many packing plants in fact closed due to worker illnesses. The low point was in early May 2020 when meat production was roughly 40% prior year levels, and actual the price dynamics and supply disruptions were exactly as described earlier in mid March.

As another example, see this post about a year ago, where I highlighted the high likelihood of rising cattle and beef prices, given the supply-side disruptions and biological lags in beef production. Indeed, we’ve seen a significant run-up in cattle prices over the past year, and more is likely to come. I’m not claiming any special insights that aren’t well known to economists working in these areas, and indeed many others were writing similar things at that time, but I am highlighting that there are folks actively doing precisely what Just advocates.

Finally, I agree wholeheartedly with Just’s conclusion (see below) and it has been the focus of some of our recent work (e,g, see here or here):

Agricultural economists can and should play a role in identifying such vulnerabilities and highlighting them for policymakers. This requires the field to adopt a forward-looking research agenda—one oriented towards identifying and preventing problems before they arise.

The challenge will be identifying institutions and mechanisms by which this sort of economic analysis can have broader influence.

Perceptions and Preferences of Soy Products

That’s the title of a new study I conducted with Brandon McFadden and Trey Malone for the United Soybean Board through the Center for Food Demand and Sustainability. We surveyed 1,200 U.S. consumers earlier this year and asked about a variety of perceptions related to soy-based products with eye towards how consumers view soy protein and soy oil relative to the alternatives.

There’s a lot in the survey, but I’ll highlight a couple results. The first is from a conceptual mapping (or pile sorting) exercise. We asked the following question.

Respondents were shown a list of 13 sources of protein and they grouped them however they saw fit. We use these groupings to conduct similarity/dissimilarity analysis based on the frequency with which each food item appeared with every other food item. Limiting to two possible dimensions of perceptions, here is the resulting perceptual map.

And, here is a corresponding hierarchical cluster analysis map.

The figures show that animal-meat products group closely together and are perceived similarly. Likewise, plant-based field crops (chickpeas, lentils, and soybeans) group together. These two groupings are perceived similarly in the vertical dimension but not the horizontal one, the latter of which seems to group on animal vs. plant. Mushrooms are probably the most distinctive protein source - with the furthest distance from other groupings.

We also asked a variety of simple questions related to beliefs about taste, price, environmental impact, health, etc.

The figure above shows consumers do not rank soybeans high in perceived healthiness relative to other proteins; however, the figure below indicates soy-based protein is viewed most positively in terms of environmental friendliness.

There is a lot more in the study including questions on how people would choose among different soy-based burgers and beef/soy blends. The whole thing is available here.

Beliefs about Beef vs. Plant-Based, Cell-Cultured, and Lab Grown Alternatives

The July 2023 edition of the Consumer Food Insights survey is now out. I want to draw attention to one set of questions we added that delved into consumers’ beliefs about beef vs. plant-based, cell-cultured, and lab grown alternatives. Each respondent was only asked one set of these questions. Cell-cultured and lab-grown refer to the same thing, but we were curious if the the alternative labeling produced a different set of beliefs.

By and large, respondents have positive perceptions of beef. Animal welfare is the only characteristic which consumers rated more positively than beef. The specific wording on this item was “Animal Welfare (if consuming the product improves overall animal well-being in the country).” Interestingly, “cell cultured” was not substantively different than “lab grown”; the later actually produced more positive views on the alternative in some dimensions such as environment and animal welfare. I say “interesting” because the start-ups seem to prefer “cell cultured” over “lab grown.”

This is the last edition of Consumer Food Insights I will be directly leading. I look forward to see the excellent work continue from the team at the Center for Food Demand Analysis.

Research Reports on Soy-based Food Demand

With the Center for Food Demand Analysis and Sustainability (CFDAS) at Purdue, we’ve been working on a project funded by the United Soybean Board and the Foundation for Food and Agricultural Research to explore the impacts of various investment alternatives on soy farmer profitability. To undertake the economic modeling, we need to understand consumer demand for a variety of soy-based foods, and the extent to which consumers are willing to substitute between soy-based foods and other products.

We’ve now released three short research reports on consumer demand for:

There is a lot of interesting material in each report. For example, here are a couple graphs showing trends in the milk and milk-alternative markets. The big story here is the rise of oat milk, which has cut into sales of other milk-alternatives.

Another interesting finding from the meat and meat-alternatives paper that is consistent with prior research is the low degree of substitutability between conventional meats and the new meat alternatives. In fact, the estimates suggest chicken is a weak complement with (rather than a substitute to) meat alternatives.

Some Career News

I’m excited to announce that I will serve as the next Vice President and Dean of the Division of Agricultural Sciences and Natural Resources at Oklahoma State University, beginning early August.

It has been an honor and privilege to serve as the head of the Agricultural Economics Department at Purdue University, and I will miss my friends and colleagues in West Lafayette. Now it’s time for a new challenge.

There are many exciting things happening at Oklahoma State University, including the near completion of the New Frontiers campaign and building, a new University strategic plan that has clear emphasis on agriculture and the Land Grant mission, and the opportunity to work with the faculty and staff to identify some key strategic opportunities to raise the impact of the Division.

I can’t promise a lot of blog output in the coming months, but I will be looking for opportunities to highlight the excellent work at Oklahoma State and to ensure the Division is actively engaged in important conversations around food, agriculture, environment, and natural resources.
