From the article:

>That said, he warns that a bid too precise may make the bidder look suspicious, or even ridiculous, to the recipient. Bidding $1.03 million for a house is one thing. Bidding $1,033,235.83 is another.

>If a bid is too precise, it may strike as strategic to the recipient, rather than being driven by superior information,” Keloharju says. “This may lead the recipient to rethink whether the bid is really informed.”

So I think $153k is an ok level of precision. $153,900 is starting to be “too precise”. $150k is definitely too round. It’s all a personal judgement call on how precise one should go but I think it’s easy to see what is too extreme (with cents in it in this case).

That extra $0.64 could lose you the job, because you'd appear to be insane and obsessed with tiny unimportant details

Not with that exact number, but on my last job change my demand was equally precise. Although we reached an agreement, my new boss said that this was "an oddly specific number" and she'd never experienced that before.

Not to the penny, but usually to a non-normative hundred. So maybe something like $153,800 instead of $150k. That has worked surprisingly well for me (someone who didn't know how to negotiate well early in my career and it probably set me back quite a bit).

Not quite,but after reading about this effect years ago I started asking for $153,000 instead of $150,000 or $155,000. I can never know for sure that this is the reason I got what I asked for, but I've always gotten what I asked for.

add one more digit. Every ten years they need to pay another cent.
