The Story Construction Tells About America’s Economy Is Disturbing
From the New York Times, Ezra Klein’s opinion piece, The Story Construction Tells About America’s Economy Is Disturbing
Here’s something odd:
We’re getting worse at construction. Think of the technology we have today that we didn’t in the 1970s. The new generations of power tools and computer modeling and teleconferencing and advanced machinery and prefab materials and global shipping. You’d think we could build much more, much faster, for less money, than in the past. But we can’t. Or, at least, we don’t.
Throughout the 1950s and 1960s, productivity in the construction sector — how much more could be done given the same number of workers and machines and land — grew faster than productivity in the rest of the economy. Then, around 1970, it began to fall, even as economywide productivity kept rising. Today, the divergence is truly wild. A construction worker in 2020 produced less than a construction worker in 1970, at least according to the official statistics. Contrast that with the economy overall, where labor productivity rose by 290 percent between 1950 and 2020, or to the manufacturing sector, which saw a stunning ninefold increase in productivity.
In the piquantly titled “The Strange and Awful Path of Productivity in the U.S. Construction Sector,” Austan Goolsbee, the newly appointed president of the Chicago Federal Reserve and a former chairman of the Council of Economic Advisers, under President Barack Obama, and Chad Syverson, an economist at the University of Chicago’s Booth School of Business, set out to uncover whether this is all just a trick of statistics, and if not, what has gone wrong.
Their paper works by process of elimination. First, they look at whether there has been less capital investment in construction than elsewhere in the economy. Nope.
Then they examine whether we’re mismeasuring construction — which would mean that sometime starting in the 1970s we began overestimating the labor or materials the construction industry used or underestimating how much it built with them, or both. They test this a few different ways, but the most interesting is to look at how many houses were built per worker, adjusted for square footage. There, the trend looks more flat than negative, and maybe slightly positive for single-family homes, but it’s far from bringing construction productivity anywhere near level with the rest of the economy.
Adding weight to the idea that this isn’t a quirk of American record keeping is that the slowdown is international. The Organization for Economic Cooperation and Development tracked construction productivity in 29 countries between 1996 and 2019. In 40 percent of them, productivity fell during that time. Syverson sent me the underlying data, and the only countries in which productivity rose at more than two percentage points per year were the Slovak Republic, Latvia, Estonia and Lithuania — poorer countries rebuilding after the crackup of the Soviet Union and the Soviet bloc.
So if it’s not underinvestment and it’s not a statistical illusion, what is it? Here, Goolsbee and Syverson seem stumped. The Wharton School of Business, for example, tracks building regulations across cities, and Goolsbee and Syverson tested regulatory burden against construction productivity. There was a slight relationship, but nothing impressive. They looked at which states saw the highest and lowest rates of productivity increases. The worst performers, Syverson said, were Alaska, Idaho, Wyoming, Delaware and Michigan. The relative stars were Georgia, North Carolina, South Carolina, Virginia and Colorado. That doesn’t lend itself to a clean story of red states and blue states, or urban states and rural states.
Syverson, for one, is skeptical that there’s any single answer. He told me:
“I don’t know how you get 50 years of decline without having multiple problems. Everyone has their pet theory. But everyone has a different pet.”
But Goolsbee and Syverson are economists. Maybe the cause is obvious to industry insiders. I called Ed Zarenski, who worked in construction, largely as an estimator, for more than 40 years and now runs the market analysis firm Construction Analytics. Zarenski, who tracks construction costs and business volume closely, agrees that there has been a slowdown. And he agrees that there is no single cause for it. But when he thinks back on what the construction industry looked like when he began his career, and what it looks like now, the anecdotes tumble out. He told me . . .
“When I first started back in the ’70s, you did one estimate on a project. You put it in, you got your bid, and if you won, you began construction. By the time I left in 2014, you did three estimates for every job before you even put the bid in. That becomes part of the cost of the job.”
Or take the job site, he said.
“The safety features on jobs when I started in the industry were not even noticeable. Safety on a job today is incredibly different.
You don’t walk across a beam, you walk around on a pathway marked for you to stay safe so you don’t fall off the side of the building. By the time I retired, one thing that took place every day, on every job site, was a mandatory 15 minutes of calisthenics before you start your workday. That’s totally nonproductive, but it led to fewer work site injuries during the day.”
And behind all that is paperwork, and paperwork, and more paperwork.
“The work we do today takes hundreds more people in the office to track and bring to completion. The level of reporting that you have to send to the government, to the insurance companies, to the owner, to show you’re meeting all the requirements on the job site, all of that has increased. And so the number of people you need to produce that has increased.”
Zarenski’s point isn’t that any of this is bad. If 15 minutes of daily calisthenics helps prevent a lifetime of back problems, it’s well worth it. The problem is that there’s more work at every level of the process, from the analyses done in the back office to the rules followed on-site.
Talking to Syverson and Zarenski left me thinking about Mancur Olson’s famous 1982 book, “The Rise and Decline of Nations.” Olson’s book begins with its own productivity mystery: After World War II, Germany’s and Japan’s cities were bombed out, their people dispirited, their economies wrecked. The question of the age, Olson writes, was “whether these abjectly defeated societies would be able to provide themselves with even the rudiments of survival.” Instead, West Germany and Japan thrived, growing far faster in that era than Britain, which had emerged victorious from the war.
Olson, an economist, was known for seminal work on the conditions under which groups would, and would not, cooperate. Here, he turned it into a theory for why nations often stagnate amid affluence and thrive in the aftermath of chaos.
His key insight is that it’s not easy for groups capable of collective action to emerge. But once they do emerge, they tend to stick around. And so, Olson suggests,
“if organizations and collusions for collective action usually emerge only in favorable circumstances and develop strength over time, a stable society will see more organization for collective action as time passes.”
The more organized groups you have, Olson thinks, the more fights over distribution you’ll have, the more lobbying and complex regulation you’ll have, the more intergroup bargaining and negotiation you’ll have, the more complexity you’ll have. Or as he puts it,
“special-interest organizations and collusions reduce efficiency and aggregate income in the societies in which they operate and make political life more divisive.”
“The Rise and Decline of Nations” is a classic economics text, but that’s not to say it’s correct. Japan, for instance, has gone from economic poster child to growth laggard. Olson’s argument would seem to imply that the United States, with its geographic protection against invasion and its long history of continuity, would be far more sclerotic than Germany, but that’s not the case. And Olson has no real answer for why so few countries that fall into crisis subsequently grow into affluence.
But Olson’s biggest miss, in my view, is his assumption that groups organize around redistribution. Olson almost completely missed the post-materialist turn in the politics of affluent countries. Some groups organize to get more of the pie, but many others organize to protect the environment, or to increase safety standards, or to preserve the feel of their communities, or to express their values. And much of this is good. It’s a gift of affluence, not a disease of affluence.
But Olson, who died in 1998, is right when he tells us that this gift comes with costs. And those costs concentrate in the areas of the economy in which the number of groups that have to be consulted mount. From this perspective, the productivity woes in the construction industry don’t seem so puzzling. It’s relatively easy to build things that exist only in computer code. It’s harder, but manageable, to manipulate matter within the four walls of a factory. When you construct a new building or subway tunnel or highway, you have to navigate neighbors and communities and existing roads and emergency access vehicles and politicians and beloved views of the park and the possibility of earthquakes and on and on. Construction may well be the industry with the most exposure to Olson’s thesis. And since Olson’s thesis is about affluent countries generally, it fits the international data, too.
I ran this argument by Zarenski. As I finished, he told me that I couldn’t see it over the phone, but he was nodding his head up and down enthusiastically.
“There are so many people who want to have some say over a project. You have to meet so many parking spaces, per unit. It needs to be this far back from the sight lines. You have to use this much reclaimed water. You didn’t have 30 people sitting in a hearing room for the approval of a permit 40 years ago.”
Some of this is expressed through regulation. Anyone who has tracked housing construction in high-income and low-income areas knows that power operates informally, too. There’s a reason so much recent construction in Washington, D.C., has happened in the city’s Southwest, rather than in Georgetown. When richer residents want something stopped, they know how to organize — and they often already have the organizations, to say nothing of the lobbyists and access, needed to stop it.
This, Syverson said, was closest to his view on the construction slowdown, though he didn’t know how to test it against the data. “There are a million veto points,” he said. “There are a lot of mouths at the trough that need to be fed to get anything started or done. So many people can gum up the works.”
This also helps explain the curious finding that ends Syverson and Goolsbee’s paper. After looking at the states with the highest construction productivity, they note that the more productive states don’t seem to gain market share in the construction industry. That doesn’t make much sense if you assume that the difficulties of construction are primarily the organization of manpower and materials. It makes more sense if you assume that the frictions are in navigating local regulations, community considerations, neighbors’ qualms and politicians’ interests.
In the cities where I’ve covered politics closely, developers are fixtures in the local political scene. They have to be.
“My feeling is the guys that know the system have a much easier time getting through the system,” Zarenski said. “They know ahead of time what they have to come into the party with and how to speak to those people and how to satisfy them, and so it goes a lot smoother for them.” But a thorough knowledge of one city or state, and establishing relationships with its key stakeholders and decision makers, won’t necessarily translate to success in another.
How do we get construction productivity rising again? I have no idea. Construction should become safer, more respectful of community concerns, and more environmentally sustainable as countries become richer and less desperate for growth. But it’s also true that many of the problems America faces — from decarbonization to affordable housing — would be a lot easier to solve if we were getting better at building, rather than worse.
There is no question that there is plenty of room for improvement in construction productivity, not least in rationalization of construction codes to acknowledge new techniques; but a large component of increased construction cost is actually a good thing. It reflects required avoidance and/or assumption of externalities that have previously been borne by people whose interests were ignored or crushed by corporate power.
Living here in the exurbs one recognizes a feature to continued construction expansion not mentioned above. Everything built new here is further from transportation and supply centers and the land upon which footings are poured and foundations built is less perfect than land formations that were selected early to become the centers for development. Living here I feel fortunate that my 1959 solid brick home does not have any settling cracks, which would not even have been a concern back in the city built above solid bedrock. On a brighter note yet, these concerns appear to be thwarting the developer that bought up the 20 acres surrounding my home.
Back in the city then urban redevelopment has its own problems, which mostly fall under the scope of this article. Demolition is more costly than clearing forest and more likely to have neighborly concerns than squirrels or even spotted owls.
Hopefully you can get into this and read about what is happening in Maricopa AZ.

Sorry, but I have not joined Nextdoor yet and am going to put that off for a couple more years until after my next platform change when I will move to Norton VPN and Lifelock. McAffee came preinstalled on my current laptop which I procured and set up in rush after spilling water on the keyboard of its predecessor.
Thanks anyway. Locally I am very plugged into our development issues via longstanding contacts in both the residential and commercial space.
I thought you may be able to still access it without joining. The complaints about builders here are extensive.
Three different builders in this comment
The conventional wisdom in these parts (central VA) is that poor construction quality goes hand in hand with lower costs and less restrictive zoning and kick backs taken by building inspectors, zoning commissions, and even elected politicians. Geographically, then this means that homes built north of the James River are of superior quality to those built south of the James River. If regulatory conditions were different here in eastern Henrico County, then construction quality would be quite poor here, but instead developers stall when they realize what it would require for them to complete their planned projects. Across the river in Chesterfield County they have far less low country to deal with and very rapid construction.
The general RoT is that there are three kinds of work; good, fast, and cheap. One can have any two of those.
I can not get you to go there. This is a small portion of the Builder Issues around us in Maricopa AZ,
We might need to reassess the term “productivity” as well. Producing what? Producing a lot of garbage houses at a fast clip may be “productive”, and then you have the “productivity” of fixing these garbage houses?
This old house (of mine) has good bones, but not much insulation. Locally there is an emerging paradigm shift away from subdivisions of single family homes except for the top 10% of homes by cost and those new homes tend to be in locations with golf courses and marinas. For ordinary working folk new means either townhouses or big in-town apartment buildings. Families are moving away from private yards unless they can afford a lawn service. In-town refurbished row houses are a popular used home alternative.
The family car is going electric, which is both unavoidable and tightly coupled with environmental consequences from decades of denial that will affect all large applications of energy.
I agree mostly. There are many things which are thrown together, missed, and purposely ignored in the construction of a house. The repairs to fix the issues afterwards are bandaids and not permanent. Hope you read my comment at 10 AM on the 9th. Some complaints by homeowners.
A close friend has been in the construction equipment business for decades. New machines are much safer than machines from when he started in the 1980s, but they are not a lot more productive as far as construction tasks go is his view. Safety is very important, but if it is not somehow in the productivity metric, then a lot of the emphasis in the construction industry around safety (highlighted in the post by an insider) just does not show up. It is more complex to operate the excavator, but the volume of dirt per operation is not different and the time between scoops isn’t much different either. The dump truck that gets loaded with the diggings has the same capacity, but is much safer on the road. Rule of thumb with a lot of things is you trade safety for speed and few make that trade anymore.
Construction – getting the project from start to finish – and construction – the erection of buildings – two different things. The actual building stuff we do better and faster. All of the other things that affect the actual building stuff, not so much.
60 years ago watching a housing tract go up was like watching a python digest a deer, now it is more like watching a ball bounce down a very long flight of stairs. In my job we called it hurry up and wait. There are a lot of things that can be done faster but don’t seem to really speed things up overall because of additional delays between the steps.
You stumbled on where I was going to go with this story as submitted by Dan.
Just like manufacturing there are a series of operations to be completed in an order which promotes the greatest efficiency and the least waste. It is apparent building a house may need to catch up.
There are many operations to be done, occurring one after another, before a house is complete. Each operation contributes to the erection of the house or building. Each operation has a time period based upon the product being constructed, A smaller home on a standard lot will go up faster than a larger home on a similar lot. Lots with varying degrees of difference may require longer time to complete. Slopes versus flat, soil differences, etc. Soil plasticity (AZ) is one I can think of right now.
How is building a house any different than building a house? You have a frame or a foundation. You add parts to each as done by various inputs of labor which have periods of time to complete. The materials for each arrive before the work is to be done. etc.
When I walk through an efficient factory, I see flows of materials, labor, and product.
When I walk through a construction site, I see dumpsters dropped on sidewalks cracking them, unused nails scattered all over, insulation and other materials blowing around, materials stacked on roof tops, incomplete houses open to the weather, etc. The latter being for long periods of time.
How do you build a house? What is the pattern and flow of materials? Safety may slow down the construction of housing so will injuries, etc, when OSHA comes out to inspect. Using Safety as an excuse, or public meetings pre-inspections as an excuse for the delays in manufacturing is rather weak.
Especially when you see the stops and goes in the construction. This is not different than manufacturing. Materials are the big costs, Overhead is next, labor is the low cost. With prefabbed parts of the house are done offsite and delivered to the site, I find the arguments being made by builders about safety, public meetings, etc, to be rather weak. They are pointing to issues which have been resolved.
“looking at the states with the highest construction productivity, they note that the more productive states don’t seem to gain market share in the construction industry.”
Which states? What populations, and what characteristics?
What are the consequences of lax controls?
For one: Onondaga Lake, Syracuse, NY. The second most polluted lake in the world. Chemical pollution in the form of heavy metals and toxic waste by the Allied Chemical Corporation continued up until 1986. An estimated 165000 pounds of mercury were dumped in the lake during the company’s operations.
This may be beyond what you expected as an answer.
