Robert "Bob" Melancton Metcalfe is an American engineer and entrepreneur who contributed to the development of the internet in the 1970s. He co-invented Ethernet, co-founded 3Com, and formulated Metcalfe's law, which describes the effect of a telecommunications network. Metcalfe has also made several predictions which failed to come to pass, including forecasting the demise of the internet during the 1990s. .. more

Hannah also finds a tradeoff between schedule unpredictability and wages: when the minimum wage is increased, scheduling unpredictability increases too.

Suggests another margin that firms are able to cut costs on when minimum wages increase.

(parallels with our work on workplace injuries).

2. Firms pass demand risk onto workers: Hannah shows that on bad-weather days (when fewer people come to buy things from these retail & hospitality businesses), there are more last-minute shift cancellations.

In most jobs, the firm bears the risk of demand shocks unless extreme (-> layoffs).

1. Schedule unpredictability means you don't work full time, but can't fill the other hours.

Avg hours worked per year in hospitality is 26, compared to 35-40 in most other industries.

But workers can't fill the spare hours with another job as they don't know when they'll be scheduled to work.

Figure shows average hours worked per week by industry. It is 25.8 in leisure and hospitality, compared to an average of 34.7 for the whole private sector.

Excited to see my JMP cited in the Economist—it highlights the tradeoffs workers could face with a higher minimum wage and suggests more worker protections like Fair Workweek laws could be important alongside minimum wage increases

Great podcast on indoor air pollution by @volts.wtf. If you’re interested in a field experiment with using real-time information on changing indoor air pollution, check out our paper: bsky.app/profile/rmet...

Today on Volts: for years, I've wanted to do a podcast on indoor air quality, and I finally found the perfect guest! Dr. Lagoudas & I discuss indoor air pollutants, the policies and technologies that can control them, and the growing need to frame indoor air quality as a basic human right.

What's the deal with indoor air quality?

From CO2 monitors to better building codes, Dr. Georgia Lagoudas outlines how to clean up the spaces where we spend 90% of our lives.

The first year is the Columbia Econ sequence, but the second and third years are a lot more flexible, allowing the freedom to pursue ideas that might not necessarily be in the Econ wheelhouse. Abundant space for creativity!

We admit 5-6 students per year into a tight knit community. The placement in the past has been outstanding, and the alumni of the program is a huge added benefit.

I’m on the #EconJobMarket! I study labor, extreme weather adaptation, and inequality.

My JMP addresses an under-studied aspect of the labor market: schedule unpredictability among hourly workers in the service sector.

I'm happy to share my #JMP on the relationship between policy intensity and effectiveness!

It challenges the idea that stricter policies are always more effective by showing that policy avoidance rises with stringency during the early period of implementation.

Now that is a cool paper, on how labour markets with hourly workers/zero hour contracts push unpredictability and slow business days onto workers.

(She exploits weather and minimum wage variations.)

Two intense and inspiring months at @columbiasipa.bsky.social have come to an end!

It has been an incredibly enriching experience to immerse myself in this thriving academic community — and the kind, curious, and passionate researchers at SIPA made it easy to enjoy every day of my research stay.

This recent working paper by @rmetcalfe.bsky.social e.a. for @centrefornetzero.bsky.social shows how effective automated EV smart charging is:

"42% reduction in household electricity demand during peak hours, with 100% of this demand shifted to low-cost, low-emission off-peak periods."

Figure shows electricity consumption throughout the day for a baseline and with an EV tariff. During the off-peak period in the middle of the night, consumption is much higher with the EV tariff, while during the peak in the early evening it is much lower.

This doesn't even make sense for like 30 reasons, there's no reason to put already-existing public data on the blockchain when it already exists and is publicly accessible, it's pretty blatantly just gonna be an attempt to pump some coin
