<p>The problem with your argument is it's whataboutism. Your argument's conclusion should be that even prescription drugs aren't necessarily good.<p>Really what is wrong is that most prescription drugs do show less tolerance. Yes, prescription drugs have tolerance, but not as fast as recreational drugs taken at recreational doses.</p>

<p>Pretty much although it's less about majority/minority preference and more about utilitarianism and economics.<p>It's possible a majority of pofeople would have been marginally happier with betamax than vhs. Even in that case, vhs can still win because a minority of people had a strong, stubborn preference for it, even if a majority of people had a weak preference for betamax.<p>If 1,000,000 people are willing to pay $5 more for video quality but 800,000 people are willing to pay $8 more for longer recording, which wins out?<p>Not to mention savings on the producer side are relevant too, not just consumer side.<p>I'm not saying the above is necessarily the case. Just pointing out that markets aren't majoritarian, they're utilitarian.</p>

<p>Kinda agree. Training the network with RL instead and penalizing collisions and rewarding collecting something like food would be interesting.<p>As long as the birds can't change direction too quickly (e.g. output acceleration, not velocity) I'd guess you get flocking.</p>

<p>Viruses get less dangerous over time. Hospitals absolutely were overwhelmed back then, and anything to reduce spread helped.<p>Virus spread follows exponential/logistic growth. Something could reduce spread 5% per month and that would still have an extremely big impact in a pandemic that lasted years. It's not necessary for any of the precautions to have been remotely close to 100% effective to argue they were helpful and important.</p>

<p>If demand increases for PPE (e.g. a righward shift of the demand curve) because of a pandemic, then prices increase but quantity demanded increases as well.<p>They may have existing futures contracts at the prior price and quantity but if quantity demanded has increased, then that means there are new orders as well that would be at the new, higher, market price.<p>The article is about them increasing their output. They could have sold the factories <i>previous expected</i> output via a futures contract. That doesn't stop them increasing output and selling in excess of any futures contracts.</p>

<p>No, that's not what is happening. From the paper:<p>>The reason is that markups along the chain of intermediation between importer and consumer can scale up the percent pass-through in
tariff costs, cumulating over distribution stages and resulting in a direct dollar impact on prices
to be greater than tariffs paid, even though the percent change in consumer price is less than the
tariff ad-valorem rate.<p>The retailer is paying more for its stock. Everyone loses despite higher prices.</p>

<p>This doesn't increase their profits because, consistent with economics, increasing prices reduces quantity. Profit depends on the amount you sell, not just the price.</p>

<p>Wages also changed since then. During COVID food outpaced wages. Since then, wages have outpaced food. Maybe not for you but on average.<p>Just like food prices didn't just jump one day, they won't just drop one day. We target 2% inflation, so they'll still go up, but slower.<p>Going up slower than wages means better affordability.</p>

<p>Retailer profits from foreign wine decreased because of reductions in sales (~12% iirc). This is textbook econ 101, profit maximization of a firm, supply and demand etc.<p>Taxes make after tax prices go up and reduce profits due to reduced quantity.<p>No reason to go searching for a "plausible excuse" or some greater  critique of culture.</p>

<p>Nobody is "trying to soften the impact of tariffs". Everyone was and is trying to maximize profits. Who ends up paying has to do with "elasticity" which roughly is about how much the tax actually impacts you.<p>In this case, it ended up that the retailer raised prices, probably because the retailer can just sell domestic wine for cheaper (close substitute). Retailer profits still didn't increase because of reductions in sales (~12% iirc) and increase in <i>after-tariff</i> inventory prices. This is textbook econ 101. Substitute, profit maximization of a firm, supply and demand etc.<p>You're confusing exporter and importer lowering prices with the retailer facing lower <i>after-tariff</i>  inventory costs. Inventory costs still went up.</p>

<p>> The seller might use this to reduce prices for their customers, but probably won't.

<p>Building apartments where people want to live generally reduces commute time. The same people need to get to the same place but usually you're letting people start closer. The same people driving less distance means less traffic, not to mention, you might even get people out of cars. Taking transit or walking are dependent on living close enough to where you want to go. Transit funding is also dependent on density.</p>

<p>Classic slam dunk on economists, except I think it's a bit of a miss. They're a classic scapegoat and punching bag but there's tons of economics research on community.<p>Saying economics doesn’t model community is a bit like saying physics doesn’t model color because some models ignore wavelength variation. It depends which models you’re looking at and what their purpose is.
There is substantial economic research on:
Social capital (e.g., Putnam, though he’s political science adjacent; economists like Glaeser formalize it)
Network effects and network structure
Repeated games and reputation
Religious participation and club goods (Iannaccone’s work is central here)
Identity economics (Akerlof & Kranton)
Trust and informal institutions
Household bargaining models
Matching theory, where who you match with specifically matters<p>I think the fact that communities are not fungible is frankly obvious. Fact is communities do die, and sometimes there are long run benefits to consider.<p>The challenge is actually nurturing and valuing community which this post doesn't actually grapple with.<p>E.g. the problem with Robert Moses wasn't just development. It was the style of development which was inherently anti-community. Nurturing a community requires common space where people bump into each other harmlessly. Highways dividing neighbourhoods, for people in their private cars to get to neighbourhoods with no commercial life and large setbacks between homes.<p>It's not that Robert Moses didn't realize community isn't fungible. It's either that he didn't realize how bad it would be for community or that he just didn't value community in the first place.</p>
