roymurdock··on Chariot is shutting down
to see if it was a viable business and they could make the numbers work (they couldn't), to show the board and investors they were staying on top of the latest trends in "micro mobility", and to acquire the software dev and startup strategy talent which it can now put towards other efforts such as self-driving or other ride hailing efforts
roymurdock··on Family Tree of Economics
yea because Hayek wanted to create an actual viable market of competitive currencies while the vast majority of cryptocurrencies today are pump n dump schemes with little to no economic thought put into them and no long term business model. why would u want to peg and limit the value of your currency when there’s a chance you can get T-Pain to blow it up sky high on hype, you sell off and make your profit that way instead of the long term profitable way of loaning money and arbitraging interest rates the way banks do now. Hayek’s thesis is still very relevant and becoming moreso in my opinion as central banks further distort the markets through unprecedented (pre 2008) actions such as direct liquidity injections through trillions in bond purchases

check out this paper by hayek arguing for denationalization of currency. free market doesn’t mean no control over creation of currency, just that they are created and traded by private enterprise instead of gov/central banks

Bitcoin/virtual currencies are a study in Austrian economics (free market for currencies instead of state/gov/central bank control)

say i pay you $1000 in wages this month

how do you decide how to allocate it between rent, food, savings, entertainment, etc.

most rational people would use some type of internal or subconscious utility calculation to decide what how to budget their income

i dont know what marginalism is or why its useful when you can simply approximate a value by looking at the price of the good/service and use that to compare with other goods and services

roymurdock··on Why I Am Not an Austrian Economist
in econ 101 utility is measured in “utils”

eg 1 banana = 10 utils, 1 apple = 5 utils, 1 car = 100 utils, etc

utils are just a proxy for money and/or time which are interchangeable through wages paid for labor

money is our real world way of valuing the utility of goods, labor, and more generally time (the scarcest resource of them all)

utility functions will never describe an individuals preferences perfectly (hell you couldn’t perfectly describe the utility of any of the transactions you make) but they’re useful when describing and predicting aggregate behavior, especially when fed a lot of consumer data (higher confidence)

all of game theory also uses the concept of utility to weigh payoffs and there are many many real world applications of game theory

its not perfect but no models are perfect, that’s why we have statistics and probability theory to guide us as well

roymurdock··on Why I Am Not an Austrian Economist
look at all of his arguments as a framing of neoclassical (math/calculus-based econ) vs. austrian (non-continuous/messy/favoring nature/functions too complex to be described and calculated econ)

1. author argues that Rothbard's austrian "value scale" approach is unable to derive the key income and substitution effects used in neoclassical modeling, but that Rothbard adds them into his framework ad hoc without properly deriving them

this has nothing to do with the reality of modeling the utility of potatoes for individuals vs. shopping malls for society, rather deriving key properties that are used in logical predictive modeling (eg my wages increase ∴ consumption curve shifts right BY income effect)

2. yeah, not related to any precepts of austrian or neoclassical economics, more of a philosophical discussion of how preferences must be revealed by action in econ rather than introspection, freezing time, or flipping a coin every time you're indifferent. he's rejecting both of their rejections of an implication of neoclassical theory, but it's not practically important, just a reflection of caplan's beliefs

3. rothbard and mises reject the notion that preferences are continuous, which means they can't be neatly drawn on 2D graphs and used in calculus. Rothbard continues to use diagrams and calculus somewhat hypocritically, while Mises doesn't use diagrams. author thinks (as do most economists) that graphing utility and preference functions as continuous and therefore being able to do useful things such as find their intersections, take their derivatives, etc. far outweighs the utility of describing them in non-continuous terms

author thinks all austrian economists reject continuous micro functions, which is untrue (just Rothbard and Mises) but supports his larger theory that austrian economics is not as useful/actionable as neoclassical

4. author is defending the principle of pareto efficiency, another fundamental neoclassical principle which allows economists to measure how free market distortions such as communism and rent control effect different groups within the economy. author is criticizing rothbard's framework which only allows one to call acts of government welfare "indeterminate" and thus be unable to measure their effect and get things done

5. defending the technical definition of "efficiency" again because the technical definition is needed to construct proofs and get things done

basically author is saying neoclassical is much more useful for getting things done with economics, and that rothbard and mises (who he takes to represent the whole school of austrian econ) didn't provide many useful tools from which others could predict/model/build off

roymurdock··on Detroit's Big Comeback: Out of Bankruptcy, a Rebirth
Then what, Detroit wouldn’t exist, instead we have a zombie city slowly dying and giving people the chance and time to escape at least.
roymurdock··on The Year in Math and Computer Science
Would be interested to hear the state of the art with quantum computing if anyone on HN can speak to it. Seems strange that people are getting recognized for using cryptography to ensure that some degree of “quantum ness” is being used in (quasi?) quantum computations?
roymurdock··on Portugal’s Economic Revival
How does austerity (reducing government expenditures in order to control/safeguard public-sector debt) cause the end of a recession (shift from negative to positive GDP growth rate)?

Saying austerity led to the end of a recession is like saying that cutting costs at your restaurant led to an increase in customers, or allowed you to charge higher prices for your food.

Greece and Italy are fighting austerity because they take the traditional economic stance - government needs to spend tax dollars on increasing investment, education, employment, etc. instead of cutting investment costs and ensuring tax money is channeled to interest payments.

Perhaps foreign investors saw that Portugal was taking its austerity seriously and began to increase investment, reassured their money would be relatively safe. But how could austerity lead to the boom in tourism and exports cited in the NY Times article?

roymurdock··on The vanished grandeur of accounting (2014)
Recognition of how certain roles are becoming extremely specialized, as Adam smith first set out in his division of labor thesis in the wealth of nations as a way to increase productivity, succinctly critiqued by Robert Heinlein: “specialization is for insects”

Accountants used to be merchants, businessmen, politicians, lenders, financiers, and insurers all rolled into one. Now they are (at entry level, or working for the state at least) seen as excel jockeys and bean counters enforcing some arcane business/legal code that nobody else wants to touch

And as much as I hate to bring in taleb, most accountants/auditors have no skin in the game, and therefore what they do is intriscally boring. If they stood to lose a pound of flesh as in the merchant of Venice when the businesses they oversee go bankrupt, perhaps they would be written about in Shakespearean terms today

roymurdock··on Corel confirms it has acquired virtualization specialist Parallels
Looks like Corel’s PE owner Vector Capital doing another tangentially related acquisition (jasc, winzip, intervideo, and Roxio are Corel’s other acquisitions under Vector) to bolster revenues, would be surprised if there was another more nefarious angle

roymurdock··on A $9T corporate debt bomb is 'bubbling' in the US economy
An increase in interest rates ~2% could trigger a large number of junk corporate bond defaults, according to the latest McKinsey analysis

The trigger for interest rates rising by that much in a short period of time is not apparent and/or explored in the article, and frankly I don't see one, but that would be the real worry, and would probably have a large, negative effect on junk government bonds as well

https://www.mckinsey.com/business-functions/strategy-and-cor...

roymurdock··on A $9T corporate debt bomb is 'bubbling' in the US economy
here's a much better article on the subject of corporate debt [1]

basically the total amount of corporate debt has jumped, but corporate debt defaults have also decreased sharply

aka corporate debt has become safer, and investors are buying it up because it has been relatively safe and provided attractive returns

if interest rates begin to rise, corporate debt defaults could start increasing, potentially severely. mass defaults could trigger another crisis

"New McKinsey Global Institute research finds that one-quarter of corporate bonds in Brazil, China, and India are from companies that are already at higher risk of default even at today’s low interest rates.

If interest rates were to rise by 200 basis points [2%], that share could rise to as much as 40 per cent. In advanced economies, most corporate borrowers are in good financial shape, but there are pockets of acute vulnerability, for instance, among speculative-grade borrowers, and in certain sectors like energy and retail...

Is the next global financial crisis at hand? We do not think so. Unlike the subprime mortgages that sparked the previous financial crisis, defaults in the corporate bond market are unlikely to have significant ripple effects across the system.

While mortgages were packaged into securitised assets and multiple layers of synthetic securities were built upon them, the same is not true of corporate bonds. Losses will therefore be sustained by the direct bond owners, but the systemic risks seen in the previous crisis are minimal."

i agree, and a 2% increase in interest rates doesn't seem anywhere near possible with today's current combination of low productivity growth, low global capital demand, and easy liquidity (granted QE is starting to wrap up in the EU at least and the US is toying with the idea of raising rates against Trump's will)

of course this is a McKinsey economist/investment manager somewhat talking their book, so draw your own conclusions, but the FT article on the state of the corporate debt is much more well-researched and written

PS subscribe to and read the FT, you won't regret it. this CNBC coverage is complete garbage

roymurdock··on Introduction to Applied Linear Algebra: Vectors, Matrices, and Least Squares
Thanks for sharing, good luck on your journey
roymurdock··on Snowboarding for Geeks
wrist guards and butt pads are very underrated. you'll be spending a lot of time falling on your ass and instinctively reaching your arms out to cushion the fall. saved me a few sprained wrists and sore cheeks when i was learning
roymurdock··on Introduction to Applied Linear Algebra: Vectors, Matrices, and Least Squares
Would be interested to hear why you’re studying machine learning. Do you see important problems you think it can solve, are you looking to make more $$ as an ML data scientist, or just generally interested in stats/data?
roymurdock··on Kelly Slater’s Shock Wave
i surf down by tower 26 occassionally and live near venice. old school beach bums are a dying breed. given the rent in venice/SM the new crowd of people moving in is all silicon beach residents/young professionals/influencers. maybe i'll see you down there some day ;)
roymurdock··on Kelly Slater’s Shock Wave
surfing culture has changed a lot...kelly slater's participation led to a big part of the change. i watched him give interviews in a recent andy irons documentary touched by god and the man is a pure machine - there's nothing laid back or surfer-like about him at all. you respect him for his complete dedication to the craft and willpower to rise to the top of the surfing world no matter what, not for his carefree, anti-corporate, all-too human personality (personified by andy irons and his tragic relapses in/out of drugs while still competing at top surfing competitions)

guaranteed if you go out to your local beach and poll the surfers, 50%+ are well-paid workers in corporate america, otherwise they wouldn't have the means and time to buy all the gear needed and live close enough to the beach to surf as a hobby

the wave machine is perfect for practicing, showing off, and competing for a televised audience, which will bring in more sponsors and of course put more money/attention into the sport. the surf you know is mostly dead [1], which isn't necessarily a bad thing, everything changes

roymurdock··on Amazon, Amid Crackdown on Seller Scams, Fires Employees Over Data Leak
neither of those examples are negative externalities

the heart and core of each company is just more efficient matching with less regulation and more technology between renters and owners of capital

roymurdock··on Amazon, Amid Crackdown on Seller Scams, Fires Employees Over Data Leak
nah i wouldn't go that far, banking employees and shareholders of recapitalized companies in 2007/2008 privatized gains and socialized losses when they were mostly bailed out with taxpayer money/federal reserve credibility instead of going under, but uber/airbnb/aws are pure efficiency plays. they increase the utilization of (what used to be) private cars, real estate, and servers respectively. there are trade offs between renting and buying, and we are moving more towards a rental economy mostly because it's more efficient in many cases to just rent what you need when you need it (opex) rather than spending big on a depreciating asset (capex)
roymurdock··on Amazon, Amid Crackdown on Seller Scams, Fires Employees Over Data Leak
problem with uber from a customer perspective is if you are a single woman taking a ride, the drivers are not full time cab employees that can possibly be fired/lose their cab medallion/permits. some women i know are considering switching to licensed cabs due to the harassment they get from uber drivers with no good mechanism to report and avoid those drivers aside from never traveling alone. as a guy, i've only had good experiences (except for the opaque surge pricing which always feels extortionate)
roymurdock··on Amazon, Amid Crackdown on Seller Scams, Fires Employees Over Data Leak
cost savings/increased efficiency is the name of the game, and first world regulations are costs SV can ignore. sometimes the quasi employees suffer the burden (but get increased flexibility), sometimes the consumer suffers (lower price but increased variance in quality of goods/service)
roymurdock··on Verizon says to shed 10,400 jobs by mid next year
Healthcare + low skilled, low wage jobs (EMS, manufacturing, parcel delivery, warehouse work) are taking a lot of slack out of the employment market

Check out where job gains in the US were in November: https://www.bls.gov/news.release/pdf/empsit.pdf

Healthcare added +32k jobs, the majority of which were ambulance drivers/EMS jobs

Manufacturing added +27k jobs, mainly in chemicals and heavy metals

Transportation and warehousing added + 25k jobs, mainly in package delivery and warehouse work

Business services added +32k jobs

All other sectors remained largely unchanged

I don't think a 50YO radio engineer at Verizon is going to be happy retraining to be an EMS or package delivery courier. Labor, especially older and higher paid (non management) positions, is not in the best position right now despite the record low unemployment rate

roymurdock··on Verizon says to shed 10,400 jobs by mid next year
Judging by the posts on this layoff board, most of the layoffs are older, more expensive folk, so it seems like Verizon is going to bring on younger cheaper labor just ahead of its rollout of 5G...we'll see how that plays out. Also it sounds like 44k people were offered the voluntary severance package and 10k accepted...almost 1/3 of the organization was offered a VSP? Insane:

roymurdock··on Group led by Thomas Piketty presents plan for ‘a fairer Europe’
what do you mean, no one will do anything

the yellow jackets are out rioting, killing, and dying to protest what they see as unfair

the prime minister has already agreed to suspend the gas tax for 6 months, and will need to make further concessions or else risk being ousted/replaced

roymurdock··on Group led by Thomas Piketty presents plan for ‘a fairer Europe’
you missed, the other side of the equation, the yellow jackets are also fed up because they perceive the gas taxes (along with tax after tax after tax under macron) to miss the upper classes and hit the lower classes disproportionately which are already struggling on a median $30k/yr income

the carbon taxes should be levied on large corporations and their shareholders rather than than low income individuals and employees

roymurdock··on Group led by Thomas Piketty presents plan for ‘a fairer Europe’
all of these fiscally conservative moves would be met with massive backlash in france, italy, the UK, and other parts of Europe, where spending on social welfare programs is a relatively large percent of the federal budget and a point of pride for many

furthermore you would be met with a huge backlash from wealthy center/progressive proponents over your anti-immigrant policy. many in power are wealthy enough to see anti-immigrant sentiment as racism rather than an economic necessity (unlike the yellow jacket protestors who are probably making around 30k euro per year - the median in france, and for whom a 25c/gallon increase in gas prices is catastrophic)

i'd be interested to hear your ideas for fiscal expansion - what should the government be prioritizing spending on to increase economic growth, rather than simply making the cuts you've suggested

roymurdock··on Group led by Thomas Piketty presents plan for ‘a fairer Europe’
show the population your plan is working by broadly improving the population's standard of living

this is currently working in both russia and china to the point where many are content with quasi-dictatorships because they've seen such a vast improvement in their quality of life through improved economies

at the end of the day more food on your table and more money in your bank account speaks volumes louder than having an infinitesimal say in who represents your interests in an increasingly dysfunctional local and federal government
