Abstract: Spectrum auctions are the primary mechanism through which governments allocate scarce radio frequencies, with outcomes that shape competition, coverage, and innovation in telecommunications markets. While traditional models of spectrum auctions often rely on strong equilibrium assumptions, we take a more parsimonious approach by modeling bidders as myopic and straightforward: in each round, firms simply demand the bundle that maximizes their utility given current prices. Despite its simplicity, this model proves effective in predicting the outcomes of Canada's 2023 auction of 3800 MHz spectrum licenses. Using detailed round-by-round bidding data, we estimate bidders' valuations through a linear programming framework and validate that our model reproduces key features of the observed allocation and price evolution. We then use these estimated valuations to simulate a counterfactual auction under an alternative mechanism that incentivizes deployment in rural and remote regions, aligning with one of the key objectives set out in the Canadian Telecommunications Act. The results show that the proposed mechanism substantially improves population coverage in underserved areas. These findings demonstrate that a behavioral model with minimal assumptions is sufficient to generate reliable counterfactual predictions, making it a practical tool for policymakers to evaluate how alternative auction designs may influence future outcomes. In particular, our study demonstrates a method for counterfactual mechanism design, providing a framework to evaluate how alternative auction rules could advance policy goals such as equitable deployment across Canada.

Future Plans:
I have like ten years of data in my log, converted from those prior prototypes. I will be adding ways to more usefully compare and analyse data going this far back.
It could maybe use a milestone function, to track singular events which don't take actual time so don't spread on the grid. Snack tracking and the like.
It could likely use a flashcard system, with spaced repetition to review the flashcards, for better memory and recall.
Synching between devices might be nice, and lots will suggest doing that through Nostr, but Nostr is a bit public. Would need an encryption layer. Do nostr relays want to relay encrypted data from one user to themselves I suspect Veilid ( https://veilid.com/ ) would be a better option. The "no servers" ethos probably includes nostr relays.
Mostly I plan just more and better ways to view the ten years and growing of data I already have. And to do some other things for a bit so my log isn't just full of "Vibecoding Exocortex" like it is the last two weeks 😉

One of the strongest factors in building and motivating an organization as a leader is saying out loud regularly that you care about people.
As Alicja frames, it's the difference between knowing what ice cream tastes like and actually eating ice cream.
It is so SO meaningful to tell people that you care about them, that you value their expertise and work, that they deserve to be respected and supported, and so on. Customize it to the individual situation: identify what someo…
