Two novel papers on housing restrictions are noteworthy, Housing Constraints in addition to Spatial Misallocation yesteryear Chang-Tai Hsieh in addition to Enrico Moretti, in addition to The Economic Implications of Housing Supply yesteryear Ed Glaeser in addition to Joe Gyourko.
Readers of this spider web log volition non move surprised at the watch that zoning in addition to other restrictions drive upward the cost of housing, in addition to that this has many bad consequences on economical growth in addition to inequality. The papers are especially noteworthy for much deeper implications.
Hsieh in addition to Moretti:
But how produce nosotros displace yesteryear anecdote? How to nosotros come upward up amongst "regulation is costing the economic scheme x pct points of growth?" Our statistical measuring system, GDP, unemployment, inflation, in addition to and thus on, was beautifully designed inwards the 1940s to mensurate real Keynesian need concepts. It isn't designed to respond the inquiry of our time, how much growth is rule costing us? We are flight inwards the dark. And Europe, perpetually inwards an Augustinian minute -- Lord, grant me structural reform, simply non yet--is also.
Well, Hsieh in addition to Moretti are doing it, in addition to yesteryear doing in addition to thus showing 1 path to answering the larger question.
Half of all the States growth for a one-half century is an astounding amount. 1964: $3,734 trillion; 2009: $14,419 Trillion. Growth = 3.05% per year. At 6.1% per year, $3734 x (1.061)^(2009-1964)=$53.6 trillion dollars!
OK, possibly that's besides huge. Well, read the newspaper in addition to encounter how they came upward amongst the number. If yous don't similar their assumptions brand unlike ones. More of import than this number is how they are coming upward amongst answers to this, the most of import inquiry of economics.
2) Models in addition to micro vs. macro
So how produce they brand the calculation? Roughly, they mensurate productivity inwards cities. They assume that people teach higher reward inwards San Francisco because at that topographic point are some real high productivity activities that withdraw maintain to move done here. They assume that business organisation could expand in addition to shape here, in addition to workers could displace hither in addition to bring together inwards those high productivity activities, both earning higher reward in addition to making to a greater extent than in addition to improve materials for the balance of us. But those workers can't move, in addition to businesses can't expand in addition to form, because housing furnish is restricted.
You tin encounter grounds for objection.
Housing costs are high inwards places similar Carmel (I think) because retired rich people similar to alive there, together amongst restricted furnish -- the amenity theory of housing cost. Workers moving at that topographic point would non earn a lot more. Maybe people alive inwards tiny apartments inwards San Francisco because they prefer it, in addition to thus restricted housing furnish is non restricting productive activity. Well come upward up amongst your ain model, in addition to cheque it out inwards the micro information equally Hsieh in addition to Moretti do. Every model has assumptions. To calculate a counterfactual -- how much would people earn in addition to businesses brand if they could displace to San Francisco -- yous withdraw maintain to produce that. It takes a improve model to rhythm out a model.
But at that topographic point is a deep lesson inwards their style of modeling: Heterogeneity. Misallocation. Dispersion. Inequality. The fundamental lesson is non that "regulation is killing the States firms on average." The the States equally a whole is doing badly because firms are inwards the incorrect identify -- misallocation. Each private business solid may experience it's doing fine. It mightiness consider moving to San Francisco, but enjoin "well, nosotros mightiness move to a greater extent than productive there, but reward are much higher because yous withdraw maintain to pay people plenty to purchase a house, in addition to thus nosotros wouldn't brand whatever to a greater extent than coin if nosotros were there." More to the point, a novel business organisation that would embody the higher productivity, teach workers to move, in addition to lay the former unproductive business organisation out of business organisation can't start.
Macroeconomics in addition to our numbers are designed unopen to the "representative firm" in addition to the "representative worker." But yous are seeing hither the macroeconomic effects of microeconomic distortion, in addition to exclusively visible inwards the amazingly large, widening in addition to persistent differences inwards productivities, wages, in addition to incomes across areas in addition to companies.
(Random additional examples: The Allocation of Talent in addition to U.S. Economic Growth, Chang-Tai Hsieh Republic of Chad Jones Erik Hurst in addition to Pete Klenow; "About one-quarter of growth inwards aggregate output per individual [from 1960 to 2010] tin move explained yesteryear the improved allotment of talent," talented african-americans in addition to women moving inwards to occupations from which they had been excluded. See inwards a higher identify middle popping numbers.; Chang Tai Shieh in addition to Pete Klenow, Misallocation in addition to Manufacturing inwards China in addition to India, or continue browsing all these authors' websites.)
3) Regulation again. There is a deeper lesson inwards this story for my telephone phone to mensurate the cost of regulations. The commons measures -- hours spent filling out forms, costs of activities required yesteryear regulators, reward of compliance employees in addition to lawyers -- are completely meaningless. Suppose that getting a edifice permit inwards the Bay Area took five minutes. (It doesn't. It's an amazingly wasteful in addition to fourth dimension consuming process. But suppose it did.) But they simply enjoin no. Well, the cost of rule measured that agency would move zero. Businesses would respond surveys, "Regulations? They aren't a problem. It's simply besides darn expensive here." Economics is e'er virtually the unseen.
The cost of rule is inwards the higher prices it imposes, the businesses that don't teach started, the people who can't displace hither to earn the high reward that high productivity brings, the higher revenue enhancement rates nosotros all must pay to bail out social safety medicare in addition to pensions because the revenue enhancement base of operations is one-half equally large equally it should be, the personal social in addition to authorities costs of the islands of poverty nosotros withdraw maintain created away from the productive cities, in addition to and thus on.
Glaeser in addition to Gyourko is a neat readable summary of broader issues inwards housing economics. This is going on a bit, in addition to thus I'll laissez passer on yous 1 quote in addition to salve the balance for some other day
Update: See also "Tarnishing the Golden State: Regulations in addition to the the States Slowdown" yesteryear Kyle Herkenho , Lee Ohanian in addition to Ed Prescott. From the abstract, the finding,

Hsieh in addition to Moretti:
...high productivity cities similar New York in addition to the San Francisco Bay Area withdraw maintain adopted stringent re- strictions to novel housing supply, effectively limiting the number of workers who withdraw maintain access to such high productivity. Using a spatial equilibrium model in addition to information from 220 metropolitan areas nosotros honor that these constraints lowered aggregate the States growth yesteryear to a greater extent than than 50% from 1964 to 2009.1) The costs of regulation. The biggest job inwards economic science correct straight off (yes, I hateful that) is, How produce nosotros mensurate the growth consequences of regulation? Looking at the Western world's sclerotically dull growth rate, in addition to listening to many anecdotes, it seems at to the lowest degree plausible that productive conception is beingness strangled yesteryear byzantine bureacracy, captured yesteryear rent-seeking in addition to anti-competitive forces. (Your other choices are, nosotros simply ran out of ideas, or some form of endless "lack of demand.")
But how produce nosotros displace yesteryear anecdote? How to nosotros come upward up amongst "regulation is costing the economic scheme x pct points of growth?" Our statistical measuring system, GDP, unemployment, inflation, in addition to and thus on, was beautifully designed inwards the 1940s to mensurate real Keynesian need concepts. It isn't designed to respond the inquiry of our time, how much growth is rule costing us? We are flight inwards the dark.

Glaeser in addition to Gyourko is a neat readable summary of broader issues inwards housing economics. This is going on a bit, in addition to thus I'll laissez passer on yous 1 quote in addition to salve the balance for some other day
In some parts of America, at that topographic point has been a revolution inwards the rule of domicile edifice over the yesteryear 50 years (Glaeser, Gyourko in addition to Saks, 2005). For most of U.S. history, local economical booms were met amongst local edifice booms, in addition to thus project could follow shocks to local productivity. However, betwixt the 1960s in addition to the 1990s, it became far to a greater extent than hard to construct inwards the nation’s most desirable locations, especially those along the coasts. Higher economical productivity inwards San Francisco straight off leads to higher prices, non to a greater extent than homes in addition to to a greater extent than workers (Ganong in addition to Shoag, 2013). This alter has both led to a transfer of wealth to a few lucky homeowners in addition to to a distorted project marketplace where people displace to regions such equally the Sunbelt that displace into specially slow to construct (Glaeser in addition to Tobio, 2008).(YIMBY stands for yeah inwards my backyard, a novel displace that fifty-fifty hither inwards the Bay expanse recognizes that letting people construct houses in addition to apartments mightiness lower housing costs.)

Deregulating existing urban the world from 2014 restriction levels dorsum to 2000 restriction levels would growth the States gross domestic product growth yesteryear nearly .5% per annum from 2000 to 2014, bringing output in addition to TFP growth roughly inwards line amongst their historical trends. The most important expanding regions from these hypothetical deregulations are California, New York, in addition to the Mid-Atlantic.Influenza A virus subtype H5N1 one-half pct scream for of growth is nonetheless huge. What's the logic? As inwards Hsieh in addition to Moratti, counterfactuals must come upward from a model
We role a diversity of state-level information sources, including the USDA, the Census in addition to the BEA to develop a full general equilibrium spatial model of the the States states
... full general equilibrium congestion forces inwards the marketplace for housing in addition to the world offset some of the gains from deregulationI teach an inkling hither that at that topographic point is a production component amongst decreasing returns to scale, in addition to thus non everyone tin displace tomorrow to SF (if they had a identify to live) in addition to earn currently high salaries. Just how many to a greater extent than people could produce goodness from whatever is the local magic is of course of report the fundamental question.
