Why Has Gotham Been in a “Housing Emergency” for 80 Years? (Part II)
Jason M. Barr March 6, 2025
New York’s rental housing vacancy rate is 1.4%—the lowest since 1969. The lack of available housing means that Gotham remains in a “housing emergency”—defined, by law, when the vacancy rate is below 5%. Why has the city’s vacancy rate never risen above 5% in over 80 years, and what will it take for New York to free itself from this emergency? This post does a deep dive into the data. Read More »

Jason M. Barr July 15, 2024
In January 2022, I proposed expanding Manhattan 2.5 miles into New York Harbor to protect Lower Manhattan from storm surges and to build 180,000 new housing units.

This blog post chronicles how he succeeded in his quest. Read More »

Left Hand Meet the Right Hand: New York’s Failure to Implement Transit-Oriented Development
Jason M. Barr January 17, 2023
Gotham has a housing affordability problem. Gotham has a transit problem. There’s a simple solution to help both.

Why do developers add extra architectural elements—like spires—to the top of their buildings?

Why Doesn’t New York Construct the World’s Tallest Building Anymore?
Jason M. Barr December 23, 2020

Jason M. Barr and Gabriel Ahlfeldt August 17, 2020
When the Empire State Building opened during the Great Depression in 1931, critics called it the Empty State Building.

This blog post shows that, first, in August 1929, when the plans were being made, the building had a strong economic rationale. And second, its long-run returns have been quite strong. Read More »

The Technology of Tall (Part III): Getting to the Core
Jason M. Barr October 23, 2019
A skyscraper’s core–the non-income generating parts used for elevators, stairwells, and plant and equipment–can take up a significant portion of a building’s total area.

The New York City transportation system has not grown in over half a century. Today, commuters are traveling on virtually the same roads as when Richard Nixon was president.

Why is housing so expensive today? To answer this we need to go back to 1916, when New York City enacted the nation’s first comprehensive zoning ordinance.

Jason M. Barr October 19, 2018
Globalization offers the promise of prosperity for humanity. But technological innovations designed to increase economic growth and the quality of life are, for a growing segment of the American workforce, having the opposite effect. As a result, many are seeking comfort in tribe, as a backlash against the perceived unfairness of the rising global marketplace. Read More »
Fire and Ice: Lessons from Historical Conflagrations for Cities Today
Jason M. Barr October 2, 2018
Throughout history, large urban fires, in cities like New York, Chicago, and Boston, were an ever-present fear and source of great suffering and damage. Recent research in economics, however, shows they had unintended benefits, and provides lessons for cities today. Read More »

In 1961, Jane Jacobs published her seminal book, The Death and Life of Great American Cities. In it, she decries large-scale interventions by the government, and promotes small-scale ideas to create diverse and vibrant neighborhoods. This blog post argues, however, that truly implementing her ideas would require something of a revolution–a revolution that even her most devout followers would not be willing to do in today’s world. Her words are used to frequently justify actions that are the opposite of what she advocated for. Read More »

Today, Jane Jacobs is revered as the “Patron Saint of Livable Cities.” In her 1961 classic book, The Death and Life of Great American Cities, she provides the key ingredients for vibrant, safe, and diverse city neighborhoods. Yet, her economic philosophy appears to bear a strong resemblance to modern libertarianism. This blog post discusses in what ways her thinking is similar. Read More »
The “Parabox”: Glass Skyscrapers and the City
Jason M. Barr July 25, 2018
Glass covered skyscrapers are generally considered to be bad for cities (and are energy inefficient); yet their numbers around the world continue to increase. This has created the glass box paradox (or “parabox”): glass skyscrapers are good for their occupants, but are likely bad for urban life. This blog post discusses the reason for “parabox,” and how it might be resolved. Read More »
The Manhattan Skyline during the Roaring Twenties
Jason M. Barr July 10, 2018
The Roaring Twenties remains a mythical time in American culture—an age of danger, of heroes, of unrestraint. During the period, Manhattan skyscrapers shot upwards to the heavens, and the world record for the tallest building was shattered three times in one year. From this, comes the belief that the rise of the skyline was due to the irrational euphoria of the age. This belief is wrong. Read More »
Zoned Out: Building Regulations and Housing Affordability
Jason M. Barr June 18, 2018
Have you heard the old joke about gravity—it’s not just a good idea, it’s the law! Ignore the law—say by jumping off a cliff in an attempt to fly—and suffer the consequences. The same can be said about supply and demand in economics—supply is not just a good idea, it’s the law. Evidently, when it comes to housing affordability, cities and nations world over are trying to ignore it at their own peril. Why is this so and what can be done about it? Read More »
Building Height and Greenhouse Gas Emissions: The Case of New York City
Jason M. Barr May 31, 2018
What is the effect of building height and size on greenhouse gas emissions? Analyzing data provided by New York City, this blog post discusses how tall buildings impact CO2 production. Are skyscrapers better for the environment? Read More »
Ugly Architecture: 130 Years of Manhattan Skyscraper Complaints
Jason M. Barr May 10, 2018
Critics of Manhattan’s new supertall buildings have a laundry list of complaints; one is that they are ugly and out of scale with their surroundings. Today’s beefs continue a 130-year tradition of grousing about skyscrapers. Some of New York’s most revered skyscrapers were originally reviled. Find out which ones. Read More »
Cities and CO2: What Can be Done?
Jason M. Barr April 10, 2018
Carbon Dioxide is the mother of all externalities. Most of us give little thought that every day we produce an odorless, invisible gas which is destabilizing the Earth’s climate. This blog post offers a politically feasible way for homeowners to begin paying for their carbon emissions based on how much they emit at home. Read More »
Incentivizing YIMBY: Greasing the Wheels to Improve Cities and Happiness
Jason M. Barr March 26, 2018
There are many local policies that cities and states can implement to increase happiness and well-being, such as improving urban transportation, promoting mixed-use neighborhoods, and redesigning streets and blocks to encourage walking and social interactions. These policies, however, are doomed to remain simply good ideas until cities can incentivizes residents to switch their positions from “Not in my backyard!” to “Yes!, in my backyard.” Read More »
Working High: Who’s on Top in Office Buildings?
Jason M. Barr March 8, 2018
Imagine that one day, walking through a crowded business district, you discover that you have a new power: you can see directly inside a skyscraper office building, as if one of the glass facades had just been removed. Before you is your very own ant farm.
Who goes where? Do different types of businesses sort themselves on different floors? If so, what might be driving this sort on high? Read More »
Name that Index! Land, Labor, or Capital?
Jason M. Barr February 20, 2018
One of the most pressing issues today is that of income inequality. What has been causing it to increase over the last few decades? To that end, we are going to play a game: Name that Index! Here we view the relative prices of different types of inputs–land, labor, and capital–over the long run and see what they suggest about our access to vital economic resources. The answers might surprise you. Read More »
The High Life? On the Psychological Impacts of Highrise Living
Jason M. Barr January 31, 2018
As the income of Planet Earth continues to rise, the construction of tall buildings proceeds apace. Many cities around the world are increasingly housing their residents in highrises. Yet, what does the research say about the impacts of highrise living on mental health, especially among the poor? Read More »
Manhattan Profits (Part III): Are Superslims Good or Bad for New York?
Jason M. Barr January 15, 2018
In the last decade, New York has seen the emergence of a new skyscraper type—supertall, superslim, ultra-luxury residential condominiums. As discussed in previous posts, the combined forces of new technology and economic demand have made them profitable projects.
However, they have attracted their share of controversy, riling up feelings of anger and frustration in certain quarters. Are they good or bad for New York City? Read More »
Why Was 2017 Another Record-Breaking Year for Skyscrapers?
Jason M. Barr January 2, 2018
The Council on Tall Buildings and Urban Habitat (CTBUH) recently issued its 2017 Year in Review for skyscraper construction around the world. As in prior years, the report has lead to a flurry of excited headlines. From The Times UK: “Taste for High Life Gives Rise to More Skyscrapers”; from ArchDaily.com: “The Results Are In: 2017 Was Another Record-Breaking Year for Skyscrapers,” and from CNN: “World Skyscraper Construction Hits All-time High.”
By why are so many skyscrapers being built each year? What is generating such dynamic growth in the world’s skylines? Read more.
Book Review: Trekonomics: The Economics of Star Trek by Manu Saadia. Pipertext, 2016
Jason M. Barr December 17, 2017
“To boldly go where no one has gone before” is, at its heart, a call for humanity to explore itself, and seek what might be possible for our modern society a century or two hence. But, lest we forget, utopia requires an economic system: a means by which goods and services are allocated in a way that frees us from harmful competition and the drudgery of the rat race.
Enter Trekonomics, a book about the underlying economics of the Star Trek universe. It nicely parts the curtain, if you will, and shows the economic superstructure of this future. As such, it offers a lighthearted challenge for us to wrestle with the economic elements that will one day make up our future, and some of which are already here. Read More.
Skyscrapers and Happiness: An International Comparison (Part I)
Jason M. Barr December 10, 2017
While skyscrapers are primarily built for their occupants, they, perforce, impose themselves on the urban fabric. We can, for example, look at the prices that people pay to rent or buy space within them to estimate their value to the tenants. However, what measures do we have about how they affect citizens more broadly?
It is important to know how skyscrapers contribute to the quality of life and our sense of well-being. Do they make us happy? While there are many angles to approach this question, the goal here is to take a “satellite view” and look at skyscrapers and the happiness of nations. Read More.
Manhattan Profits (Part II): Return on Investment for a Superslim Skyscraper
The Manhattan skyline was created by developers seeking their fortunes. Skyscraper heights, frequencies, types, and locations are based on the profits they generate. Today, the princes of height are the superslim luxury residential towers, such as 432 Park Avenue, 225 West 57th Street/Central Park Tower, and 111 West 57th Street/Steinway Tower.
These towers, like all supertalls before them, are controversial. To understand a bit more about them, however, it might be of interest to play developer, and estimate the profits to constructing one. To do this I have created plans for a hypothetical 80-story superslim condo—the Barr Tower—on 57th Street. Read more.
Manhattan Profits (Part I): The Economics of the Superslim
By Jason M. Barr November 19, 2017
In the last decade, New York has seen a resurgence of skyscrapers. In particular, has been the rise of the superslims—super-tall, ultra-thin luxury apartment buildings.
The definition of a superslim comes from the ratio of the building’s ground floor width to its height. The Empire State Building, for example, is relatively chunky, with a base-to-height ratio of 1:3. On the other hand, 432 Park Avenue has a slenderness ratio of 1:15; 53 West 53rd Street (the MoMA Tower) is 1:12; and 111 West 57th Street (the Steinway Tower), when completed, is to have a record-breaking ratio of 1:24. 1:10 is the benchmark for a slim tower.
Why are so many being built? Read more…
Broken Clockism: The “Skyscraper Curse” is Bogus
By Jason M. Barr November 5, 2017
In 1999, an economist named Andrew Lawrence thought he saw a relationship between the business cycle and skyscrapers; he dubbed this the “Skyscraper Index,” and it purports to demonstrate the “Skyscraper Curse,” which is,
an unhealthy correlation between construction of the next world’s tallest building and an impending financial crisis: New York 1930, Chicago 1974; Kuala Lumpur 1997 and Dubai 2010. Yet often the world’s tallest buildings are simply the edifice of a broader skyscraper building boom, reflecting a widespread misallocation of capital and an impending economic correction.
It has proven a very seductive idea, and the media and public have glommed onto it as some kind of infallible truth. But the idea that the construction of the world’s tallest building is a harbinger of economic doom is specious. Read more…
Growing Up: Skyscraper Heights over the 20th Century
By Jason M. Barr October 20, 2017
In the year 1848, a stroll down lower Broadway in Manhattan would have revealed a decidedly low-rise town. The reason was simple: the only way to get to the top floor was to climb the stairs. Humans, unlike birds, do not have the anatomy to defy gravity (what would offices for birds look like anyway?). As a result, property owners had no incentive to build taller, since few would pay to be on higher floors. Read more…
The Birth of Height: The World’s First Skyscraper
By Jason M. Barr October 7, 2017
What was the world’s first skyscraper? If you do have an answer, you would be, most assuredly, wrong (sorry). Any skyscraper that we claim as the “first” is merely a convenience—a social convention to provide a simple answer to a complicated question.
But why would it be wrong? For two reasons…Read more...
