A couple months ago, I was asked to give a talk at a TEDx event put on at Purdue University. The video is finally available online. I talked about the evolution of animal agriculture and the impacts on food prices and animal welfare, and I ended with my proposal for an animal welfare market, which I've previously written about here and here.

Agricultural Marketing and Price Analysis
About 10 years ago, Bailey Norwood and I published an undergraduate textbook entitled Agricultural Marketing and Price Analysis. The book was originally published by Prentice-Hall. Over the years, we'd considered revising and updating various portions of the book, but the publishers were never appeared interested in releasing a second edition.
Now, Waveland Press was secured the rights to publish the textbook (their site for the book is here). For now, this is just a reprint of our original version, but they've agreed to put out a new edition in the future as well. Bailey and I will probably pick up a couple co-authors who have been using the book in class. More on that in a year or two when a new edition is set to drop.
For now, you can enjoy the new cover.
Or, if you can read Greek, you can also buy that translation here.

That's the title of a new book edited by Jessica Eise and Ken Foster that was just released last week. The book is a collection of essays primarily from my colleagues in the Department of Agricultural Economics here at Purdue, but it includes contributions from Purdue faculty in other academic disciplines as well. I had the privilege of writing the afterward.

Gains to Chinese Agricultural Research and Extension
Last week, Nature published this piece on a massive study conducted by Chinese agricultural researchers. Accompanying the piece was a summary/editorial describing the study:
“Running from 2005 to 2015, the project first assessed how factors including irrigation, plant density and sowing depth affected agricultural productivity. It used the information to guide and spread best practice across several regions: for example, recommending that rice in southern China be sown in 20 holes densely packed in a square metre, rather than the much lower densities farmers were accustomed to using.
The results speak for themselves: maize (corn), rice and wheat output grew by some 11% over that decade, whereas the use of damaging and expensive fertilizers decreased by between 15% and 18%, depending on the crop. Farmers spent less money on their land and earned more from it — and they continue to do so.”
The project appears to have created substantial economic benefits. The authors of the study write:
“Direct profit, calculated from increased grain output and reduced nitrogen fertilizer use, was US$12.2 billion (Table 1), which does not include relevant environmental benefits associated with reductions in reactive nitrogen losses and in GHG emissions. On the basis of the rough estimates, the cost:benefit ratio would be 1:226. ”
The cost-benefit ratio is in some ways over- and in other ways under-estimated. The benefits are over-estimated in the sense that it does not appear it takes into consideration the fact that greater grain production will dampen prices (it is also unclear how the benefits and costs are discounted or not over time). The benefits are under-estimated because they do not include any of the environmental improvements.
It is useful to contrast these findings with the rather large research on the value of agricultural R&D and extension investments in the U.S. Jin and Huffman calculated the rate of return on spending on agricultural extension in the U.S. at 100%. More broadly, Julian Alston gave the fellow's address at this this year's AAEA meetings on precisely this topic, and his remarks were recently published in the American Journal of Agricultural Economics. He writes:
“Our estimates (Alston et al. 2010a, 2011) indicate that U.S. federal and state government expenditure on agricultural research and extension generates benefit-cost ratios of at least 10:1 (more likely 20:1 or 30:1)—evidence of a serious underinvestment. Pardey and Beddow (2017), echoing Pardey, Alston, and Chan-Kang (2013), suggested that a reasonable first step would be to double U.S. public investment in agricultural R&D—an increase of, say, $4 billion over recent annual expenditures. A conservatively low benefit-cost ratio of 10:1 implies that having failed to spend that additional $4 billion per year on public agricultural R&D imposes a net social cost of $36 billion per year”
Given the lower level of development in China, it is certainly possible to imagine that the rate of return on investments in agricultural research and extension being higher than is the case in the U.S. But, can the benefit cost ration really be 10 times higher in China than the U.S. (226:1 vs. 20:1)? One interesting thing about Chinese study in Nature is that, if I read correctly, it didn't entail development of any new genetics, pesticides, etc; rather it seemed to largely entail the application of previously developed "science" and practices to the particular geographies in question, and as such, the costs might have been much lower than in situations where new technologies are being created.
In a sense, the shows an enormously high value to "better information." This contrasts with perspectives such as this one by David Pannell, who argues that better technologies are much more impactful than "better information." One way to reconcile this seeming paradox is that that the "information" conveyed to the Chinese farmers was to use better technologies and practices that were already known to exist. Here in the developed world, the knowledge/technologies are likely already more widely dispersed.
I'll end with this quote from Alston's paper, who articulated the value of increased productivity in a createive way:
“Clearly agricultural productivity growth is enormously valuable. Of the actual farm output in 2007, worth about $330 billion, only one-third (i.e., 100/280 = 0.36) or about $118 billion could be accounted for by conventional inputs using 1949 technology, holding productivity constant. The remaining two-thirds (i.e., 180/280 = 0.64) or about $212 billion in that year alone, is attributable to the factors that gave rise to a 180% increase in productivity since 1949—including improvements in infrastructure and inputs (if not captured already in the indexes), as well as new technology, developed and adopted as a result of agricultural research and extension, and other sources of innovations.”
Understanding the Impacts of Food Consumer Choice and Food Policy Outcomes
The journal Applied Economics Perspectives and Policy just published a special issue in which agricultural and applied economists provide their thoughts on how we might help tackle some of society’s most difficult problems and challenges. I co-authored one of the articles with Jill McCluskey. Here's the abstract:
“The food consumer plays an increasingly prominent role in shaping the food and farming system. A better understanding of how public policies affect consumer choice and how those choices impact health, environment, and food security outcomes is needed. This paper addresses several key challenges we see for the future, including issues related to dietary-related diseases and the efficacy of policies designed to improve dietary choices, trust in the food system, acceptance of new food and farm technologies, environmental impacts of food consumption, preferences for increased food quality, and issues related to food safety. We also identify some research challenges and barriers that exist when studying these issues, including data quality and availability, uncertainty in the underlying biological and physical sciences, and the challenges to welfare economics that are presented by behavioral economics. We also identify the unique role that economists can play in helping address these key societal challenges.”
