Larry Summers' Martin Feldstein Speech
The latest NBER Reporter has the vox communication Larry Summers gave at the annual NBER "summer camp" for economists. As yous would expect, in that location are some actually interesting bits, which provoked a goodness lunchroom discussion. To my take away heed it (and this weblog post) gets much amend toward the end.
The organizing thread is Larry's worries nearly long term trends inwards work as well as income distribution, as well as how trends inwards productivity as well as conception touching on it. If the tidings did non have got negative connotations, I mightiness term the speak "neo-Luddite," the worry that this time, dissimilar all the others, technical change, primarily data technology, volition live actually bad for workers.
Ouch. "Unemployment" figures inwards the pop press, but it is the fraction of people actively looking for jobs. The far bigger worry amid many economists is the rising inwards "non-employment." One inwards x men, 25-50, are merely non working at all or fifty-fifty looking for work.
Casey Mulligan mightiness signal out that Social Security disability is entirely ane of hundreds of distortions as well as punitive marginal effective taxation rates pushing people out of work.
And what does that terminal judgement mean? "Technological as well as social changes" are non disabling millions of people -- function is physically safer than ever. Does he hateful that SSDI is a desirable ruse for our authorities to surrender as well as pay people to non function whose productivity has fallen below a sure threshold?
Anyway, for the residual of Larry's speak he focuses on depression wages, which is the deeper driving question. In measure economic science Y=AF(K,L), either to a greater extent than engineering scientific discipline H5N1 or to a greater extent than working capital missive of the alphabet K enhance the marginal production of undertaking as well as hence wages. So why are nosotros at nowadays suspecting that technological progress is reducing wages?
Larry position upwards a suggestive production component Y = F(βK, L + λ(1 ‒ β)K) inwards which to a greater extent than working capital missive of the alphabet is supposed to lower wages. I spent a few hours trying to function out his "moment's thought," but was unable to verify its conjectured properties. This looks similar a goodness job laid for a micro story or a blogger amongst to a greater extent than fourth dimension on his hands.
Next, as well as getting to a greater extent than interesting, he position upwards this tabular array of CPI values
The issue: Are "stagnant wages" actually stagnant inwards existent terms? Well, measured inwards terms of toys or televisions, non at all. In terms of, say, tuition at Harvard as well as Chicago, yep indeed.
About televisions,
The job is, early on adopters are willing to pay a large premium for novel goods. I'm non an skilful on hedonic adjustment, but ane wonders how it corrects for early-adopter toll discrimination.
But on to the existent point, actually the most interesting of the talk. However measured, "things" have got gotten actually cheap. They've likewise gotten a lot better. Many things have got gotten so inexpensive that they are modest fractions of our budgets, so farther productivity improvement does non present upwards inwards cost of living measures. Many services have got non gotten cheaper. We count on productivity growth to enhance living standards, so the large number is actually productivity growth inwards services:
And yous larn some other component of the picture. The large toll growth, as well as the large work growth, are happening inwards heavily authorities run or authorities influenced sectors. Like wellness care.
Blog readers volition know where I stand. Sectors similar wellness assist tin give notice have got huge productivity improvements if governments travel out of them. Services similar airlines, parcel delivery, as well as telecommunications, have got all seen huge productivity improvements when governments got out of them. Service sector similar retail that our authorities never was inwards (other than to tiresome downwards low-cost entrants that serve poor people, from A&P to Wal-Mart) have got seen huge productivity gains.
Those improvements benefited the denominator of consumer's existent wages, as well as lowered the numerator of income inequality -- pilots don't larn paid what they used to. As Larry points out, the burden of taxation goes amongst the foursquare of the taxation rate, so every bit the economic scheme shifts to services it is merely impossible for the authorities to decease along expanding. But his (to me) depressing forecast of where nosotros are going remains (to me) sadly true.
Larry closes amongst the deepest sentiment of all.
The origin inquiry is, what distinguishes these novel "service" transactions from "widgets?" Larry's listing is, from above, "issues of key scarcity: energy, the solid soil nether the houses nosotros buy, as well as goods as well as services that are produced inwards complicated, heavily public-sector-inflected ways," as well as afterwards "sectors where belongings rights, scarcities, intellectual property, as well as the similar are of key importance."
One describe of reasoning looks for a Definition past times going at ane time to world choice, as well as focuses on public-sector-influenced. This does non boom me nevertheless to live peculiarly correlated amongst widget vs. non-widget. Yes, our authorities has become, inwards the apocryphal quote, an insurance fellowship amongst an army. But other governments have got run steel companies, locomotive factories, as well as fossil oil drilling as well as refining operations amongst much the same productivity results every bit nosotros are seeing inwards government-provided services.
I detect it to a greater extent than interesting to call upwards nearly the someone sector part. What distinguishes medical assist (ok, vet, lasik, as well as plastic surgery; let's call upwards nearly marketplace economics) as well as software evolution from widgets?
I don't call upwards "fundamental scarcity" is it. Energy is turning out non to live fundamentally scarce after all. The long-run provide bend is really elastic. Land inwards mid-town Manhattan, or inwards the parts of the San Francisco peninsula permitted for construction past times zoning laws is indeed scarce. Land on the outskirts of Las Vegas is cheap.
That leaves "property rights, scarcities" -- scarcity of people amongst desired skills -- as well as "intellectual property." To which I mightiness add together data as well as expertise.
So how attain nosotros call upwards of a the world where things are gratis as well as economical transactions consist of performing services for each other -- services that require fourth dimension (substituted for past times software) expertise, as well as substantial human capital? That does boom me every bit the of import Big Question. Maybe Larry's production component is a house to start.
This gets us far away from Larry's neo-Luddite worries. Which I don't hateful to denigrate. But nosotros kind of know the answer. The returns to science volition live large. The fascinating inquiry is why, after xxx years of a rising science premium, the production of science seems non to have got flooded the market, driving downwards that premium? Are the authorities involvement inwards education, as well as the disincentives to function Larry mentions maybe fifty-fifty to a greater extent than powerful disincentives to human working capital missive of the alphabet accumulation than they are to getting upwards to decease to a poor minimum-wage job?
The organizing thread is Larry's worries nearly long term trends inwards work as well as income distribution, as well as how trends inwards productivity as well as conception touching on it. If the tidings did non have got negative connotations, I mightiness term the speak "neo-Luddite," the worry that this time, dissimilar all the others, technical change, primarily data technology, volition live actually bad for workers.
Ouch. "Unemployment" figures inwards the pop press, but it is the fraction of people actively looking for jobs. The far bigger worry amid many economists is the rising inwards "non-employment." One inwards x men, 25-50, are merely non working at all or fifty-fifty looking for work.
And every bit yous would expect, these patterns are substantially to a greater extent than pronounced if yous are less educated. They are substantially to a greater extent than pronounced if yous are inwards a disadvantaged grouping than if yous are inwards an advantaged group.Larry treads lightly, I think, around the number non-employment raises. If our economic scheme has a rising "skill premium," inwards economist language, or "doesn't provide goodness steady jobs to high schoolhouse grads similar it used to," inwards the to a greater extent than colorful Grease-era nostalgia of, say, the New York Times, or fifty-fifty if the haves are exploiting greater "power" against the have-nots, yous would facial expression to see, as well as worry about, wages of low-skill people. But yous would non facial expression to run into an regular army of 25-54 twelvemonth former men not working at all. Wages inwards People's Republic of Bangladesh are really low. And 25-54 twelvemonth former men function actually hard. Wages inwards the U.S. of A. inwards 1910 were actually low, as well as 25-54 twelvemonth former men worked actually hard. If they didn't, they as well as their families didn't eat. Which, to live clear, I am non applauding. We're merely trying to sympathise a phenomenon. How attain poor opportunities (if that's the problem) inwards the U.S. of A. interpret into non working rather than working at depression wages? Larry:
This is associated amongst what is likewise a defining characteristic of our time. In the U.S. of A. today a higher fraction of the workforce receives disability insurance than does production function inwards manufacturing...
These phenomena are related. No ane could give a Feldstein lecture without recognizing the possibility that a social insurance computer programme had a distorting disincentive number as well as that is sure the instance amongst honour to disability insurance. But I call upwards it is likewise fair to state that the evolution as well as growth of disability insurance is substantially driven likewise past times the technological as well as social changes that are leading to a smaller fraction of the workforce working.
And what does that terminal judgement mean? "Technological as well as social changes" are non disabling millions of people -- function is physically safer than ever. Does he hateful that SSDI is a desirable ruse for our authorities to surrender as well as pay people to non function whose productivity has fallen below a sure threshold?
Anyway, for the residual of Larry's speak he focuses on depression wages, which is the deeper driving question. In measure economic science Y=AF(K,L), either to a greater extent than engineering scientific discipline H5N1 or to a greater extent than working capital missive of the alphabet K enhance the marginal production of undertaking as well as hence wages.

Larry position upwards a suggestive production component Y = F(βK, L + λ(1 ‒ β)K) inwards which to a greater extent than working capital missive of the alphabet is supposed to lower wages. I spent a few hours trying to function out his "moment's thought," but was unable to verify its conjectured properties. This looks similar a goodness job laid for a micro story or a blogger amongst to a greater extent than fourth dimension on his hands.
Next, as well as getting to a greater extent than interesting, he position upwards this tabular array of CPI values
| Good or Service | September 2012 CPI Value (1982-4 = 100) |
| College Tuition as well as Fees | 706 |
| Medical Care Services | 445 |
| Medical Care | 419 |
| Services | 272 |
| Energy | 258 |
| Food | 234 |
| All Items | 231 |
| Housing | 223 |
| Transportation | 224 |
| Apparel | 127 |
| Durables | 112 |
| Toys | 53 |
| Televisions | 5 |
The issue: Are "stagnant wages" actually stagnant inwards existent terms? Well, measured inwards terms of toys or televisions, non at all. In terms of, say, tuition at Harvard as well as Chicago, yep indeed.
About televisions,
Television sets at v stand upwards out. That is land a reflection of a rather energetic hedonic endeavour past times the Bureau of Labor Statistics.This is an interesting side Federal Reserve notation on measurement. Do televisions actually cost 1/20th of what they cost inwards 1980? H5N1 TV inwards 1980 cost nearly $500. H5N1 TV at nowadays costs nearly $500. Every reckoner I have got bought since 1982 has cost $2,000. What's going on? Televisions at nowadays are much amend than televisions dorsum then. The BLS accounts for this fact past times comparison televisions when a novel model comes in. Suppose an former underground TV is selling for $500. The origin LCD tv set comes inwards as well as sells for $5,000, as well as a few hedge fund managers purchase them. The BLS figures that the LCD TV is the same every bit 10 former fashioned TVs. LCD TV prices driblet to $500, as well as nobody buys underground TVs whatsoever more.The BLS figures that LCD TVs are silent the same every bit 10 underground TVs, so the toll of all TVs has gone downwards past times a component of 10, exactly every bit if yous could purchase a underground TV for $50.
The job is, early on adopters are willing to pay a large premium for novel goods. I'm non an skilful on hedonic adjustment, but ane wonders how it corrects for early-adopter toll discrimination.
But on to the existent point, actually the most interesting of the talk. However measured, "things" have got gotten actually cheap. They've likewise gotten a lot better. Many things have got gotten so inexpensive that they are modest fractions of our budgets, so farther productivity improvement does non present upwards inwards cost of living measures. Many services have got non gotten cheaper. We count on productivity growth to enhance living standards, so the large number is actually productivity growth inwards services:
In those parts of the economic scheme that are good modeled past times the introductory economic science textbook handling of widgets - firms producing a thing amongst workers amongst increasing marginal costs inwards a somewhat competitive industry, such every bit durables, clothes, as well as cars - we've seen continuing, really substantial growth inwards existent reward every bit measured past times the purchasing powerfulness of things that our economic scheme produces. The argue that [measured] existent reward inwards aggregate have got stagnated is that much of what people purchase are things where in that location are issues of key scarcity: energy, the solid soil nether the houses nosotros buy, as well as goods as well as services that are produced inwards complicated, heavily public-sector-inflected ways. Medical assist as well as educational services are examples of the latter category....Larry puts upwards a nautical chart of where the jobs are going to live inwards the future,
And yous larn some other component of the picture. The large toll growth, as well as the large work growth, are happening inwards heavily authorities run or authorities influenced sectors. Like wellness care.
As a society, nosotros are going to demand to come upwards to grips over the side past times side pair of decades with..the propensity for the slow-growing [and fast-inflating!] sectors to halt upwards inwards the world sector...
Whether the expansion of those sectors every bit a part of the economic scheme necessitates a growing part of the world sector inwards the economy, or whether the part of healthcare as well as instruction that takes house inwards the world sector should turn down volition live a affair of keen world debate. As a country, as well as non without controversy, nosotros attain non seem to live moving toward a smaller world role inwards healthcare. Nor attain other countries inwards the world. But that will, perhaps, modify over time.sIndeed. One decision [not Larry's!] yous tin give notice describe is that greater authorities involvement has caused lack of competition, innovation, productivity growth as well as toll increase inwards the sectors it has come upwards to dominate, as well as so is a large component of the motility of stagnant existent reward measured past times CPI. I don't have got whatsoever sentiment past times what economical or political strength Larry imagines larger shares of whatsoever manufacture "necessitate" authorities involvement.
Blog readers volition know where I stand. Sectors similar wellness assist tin give notice have got huge productivity improvements if governments travel out of them. Services similar airlines, parcel delivery, as well as telecommunications, have got all seen huge productivity improvements when governments got out of them. Service sector similar retail that our authorities never was inwards (other than to tiresome downwards low-cost entrants that serve poor people, from A&P to Wal-Mart) have got seen huge productivity gains.
Those improvements benefited the denominator of consumer's existent wages, as well as lowered the numerator of income inequality -- pilots don't larn paid what they used to. As Larry points out, the burden of taxation goes amongst the foursquare of the taxation rate, so every bit the economic scheme shifts to services it is merely impossible for the authorities to decease along expanding. But his (to me) depressing forecast of where nosotros are going remains (to me) sadly true.
Larry closes amongst the deepest sentiment of all.
..I invite yous to consider how the prodigious modify associated amongst data engineering scientific discipline that may live qualitatively different from past times technological modify may have got defining implications for our economic scheme going forward. If I have got caused yous to reverberate on the fact that really substantial relative toll changes are probable to live associated amongst dramatic changes inwards the construction of employment, the nature of economical activity, as well as the relative importance of the widget-producing theater inwards our economy, as well as to consider the implications this volition have got for the futurity of the dependent land amongst which I began my career inwards economic science nether Marty's tutelage, world economics, so I volition have got served my role this afternoon.This is a sentiment that's been on the dorsum of my take away heed for a long fourth dimension every bit well. Our Econ 101 widget fellowship as well as provide as well as demand graph are actually strained every bit a description of most modern transactions. Pretty much anything yous purchase represents non the transfer of a good, but the application of someone's expertise as well as information. Even getting your automobile fixed, yous are non buying someone's undertaking every bit if yous or I could attain it but exactly have got amend things to do. You're buying expertise, information, the fruits of human as well as organizational capital. There is a Big Paper to live written thinking through how an economic scheme where "things" have got decease gratis but services, information, as well as expertise flora economical transactions.
The origin inquiry is, what distinguishes these novel "service" transactions from "widgets?" Larry's listing is, from above, "issues of key scarcity: energy, the solid soil nether the houses nosotros buy, as well as goods as well as services that are produced inwards complicated, heavily public-sector-inflected ways," as well as afterwards "sectors where belongings rights, scarcities, intellectual property, as well as the similar are of key importance."
One describe of reasoning looks for a Definition past times going at ane time to world choice, as well as focuses on public-sector-influenced. This does non boom me nevertheless to live peculiarly correlated amongst widget vs. non-widget. Yes, our authorities has become, inwards the apocryphal quote, an insurance fellowship amongst an army. But other governments have got run steel companies, locomotive factories, as well as fossil oil drilling as well as refining operations amongst much the same productivity results every bit nosotros are seeing inwards government-provided services.
I detect it to a greater extent than interesting to call upwards nearly the someone sector part. What distinguishes medical assist (ok, vet, lasik, as well as plastic surgery; let's call upwards nearly marketplace economics) as well as software evolution from widgets?
I don't call upwards "fundamental scarcity" is it. Energy is turning out non to live fundamentally scarce after all. The long-run provide bend is really elastic. Land inwards mid-town Manhattan, or inwards the parts of the San Francisco peninsula permitted for construction past times zoning laws is indeed scarce. Land on the outskirts of Las Vegas is cheap.
That leaves "property rights, scarcities" -- scarcity of people amongst desired skills -- as well as "intellectual property." To which I mightiness add together data as well as expertise.
So how attain nosotros call upwards of a the world where things are gratis as well as economical transactions consist of performing services for each other -- services that require fourth dimension (substituted for past times software) expertise, as well as substantial human capital? That does boom me every bit the of import Big Question. Maybe Larry's production component is a house to start.
This gets us far away from Larry's neo-Luddite worries. Which I don't hateful to denigrate. But nosotros kind of know the answer. The returns to science volition live large. The fascinating inquiry is why, after xxx years of a rising science premium, the production of science seems non to have got flooded the market, driving downwards that premium? Are the authorities involvement inwards education, as well as the disincentives to function Larry mentions maybe fifty-fifty to a greater extent than powerful disincentives to human working capital missive of the alphabet accumulation than they are to getting upwards to decease to a poor minimum-wage job?
