I’ve created a new website that aims to make agricultural data easily accessible to researchers and the public. All graphs and maps are downloadable as images. https://t.co/vOhasQG7iC (1/10)

Hal White was a man before his time. He is chronically under appreciated. He wrote one of the most highly cited papers in the history of economics (White (1980)). Absolute lock for the Nobel if he had lived longer.

Xiaohong Chen (Yale) presented “Neural Networks for Economics: Theory & Inference”. Long before today’s AI boom, econometricians (Chen, White, and others) built foundations for neural nets as sieves. These tools are now crucial for NN-based estimation and inference in economics.

Nowadays, dystopically: Professor stands at the front of a dimly lit room and talks through slides projected onto a giant screen, occasionally writing on a whiteboard with pens that don’t work. A small number of students stare blankly at their laptops or phones.

[Aaron Smith @ASmithUCB]

In this week's Ag Data News, I wrote about teaching large classes in the age of AI.

The old days, nostalgically: Professor stands at the front of the room and talks while writing feverishly on the chalkboard. Riveted students take detailed notes and ask incisive questions. If they have to miss class, they borrow a friend’s notes and transcribe them to keep up.

[Aaron Smith @ASmithUCB]

Most of the class didn’t show up. They told themselves they would download the slides and watch a recording of the lecture later, but they probably won’t because ChatGPT will do their homework.

In reality, things aren’t that dystopian, and the old days weren’t quite that good.

Please join us for an in-person workshop on the land-use effects of biofuels on May 28 at UC Berkeley.

There is little consensus on this topic. This conference will bring together researchers with a range of perspectives to hash it out.

Today, I responded to some critiques of our analysis. In short, our analysis did not contain faulty assumptions or facts. https://t.co/PCdJQVrAKh

California Governor Gavin Newsom has proposed a new tax credit that would allow oil companies that pay diesel taxes to reduce their tax bill if they also produce sustainable aviation fuel.

[Aaron Smith @ASmithUCB]

Last month, my co-authors and I showed that it would reduce road funding, raise gasoline and diesel prices, and deliver expensive small carbon emissions reductions. https://t.co/RnEkRdtpAa

@dunnde Just saw D4 jumped last two days.

[Aaron Smith @ASmithUCB]

@dunnde Anticipating this could be one reason D4 barely declined as fossil diesel prices increased in the last month. Maybe.

“While using 20 year warming instead of 100 year warming has been a convenient way for opponents of natural gas to inflate the impact that natural gas has on the warming of the planet, it also makes a mockery of the notion that climate change is centrally an issue of intergenerational equity.”

Farmer pays $5–$8 per cow per month.

A New Zealand company puts a solar-powered smart collar on cows.

It tracks location 24/7, health, temperature, chewing activity, breeding.

Farmer just opens a simple app and draws a line on the map.
That line becomes the fence.

As cows approach the boundary, the collar beeps and vibrates.

With one tap, the whole herd moves to fresh grass or the milking shed.

No physical fences. Less labor. Huge cost savings for farmer.

Already on 700k cows across New Zealand, Australia, and the US.

and now in talks to raise at a $2B valuation led by Peter Thiel.

[Aaron Smith @ASmithUCB]

People, it's daylight saving not daylight savings.

And it's a good system.

[Aaron Smith @ASmithUCB]

@asymmetricinfo Very real. Expensive, so currently used only in crops with few herbicide alternatives, such as onions or anything organic. The laser weeder is best at killing really tiny weeds (1mm). Other tech uses spray instead of lasers, is better for larger weeds. https://t.co/6lnOshN0At

[Aaron Smith @ASmithUCB]

This week in Ag Data News (cross posted in EI Blog), California now allows more ethanol in gasoline — is this going to save drivers money?

Short answer: No

@dunnde @OilandGibbs @ScottIrwinUI @CCapLP @JarrettRenshaw Well, nerds like me will advocate for higher ILUC values or some other way of dealing with LUC.

In LCFS: biogas, electricity and others benefit from higher credit prices. One way to raise credit prices is to limit liquid biofuel credit values by imposing higher ILUC.
