Supply and Demand in Relation to SSOL

The most common argument against economic intervention is that the market will correct itself: prices get too high, demand falls, competitors enter, supply expands, prices come back down. This argument is correct - for elastic markets. For inelastic markets , it is wrong, and pretending otherwise is how essential goods become unaffordable.

How market self-correction actually works

Consider the hardware store fastener aisle. Nails and screws are often sourced from a single manufacturer, yet prices remain low. That is not because of active price competition - it is because of the credible threat of competition. If the manufacturer raised prices too high, another supplier could enter the market and undercut them. Customers can wait. They can shop around. There is no urgency that hands the manufacturer permanent pricing power.

This works because fasteners are elastic. Nobody is going to pay any price for nails. If they become too expensive, people delay the project, use alternatives, or find a different supplier. The demand-side discipline is real and effective.

The threat of competition, not competition itself, is what keeps prices honest in elastic markets. The fastener manufacturer does not arbitrarily raise prices because of lack of competition - they do not raise prices because a competitor could enter if they did. That credible threat is enough. The market disciplines itself in anticipation of what would happen if it did not.

This matters for SSOL because the same logic applies in reverse. When large employers have a direct financial stake in lower housing costs, they do not need to build housing themselves. The credible threat that they will lobby for zoning changes, fund competing developers, or relocate to lower-cost markets is enough to change the political calculation for those who currently benefit from restricted supply. The possibility of lower costs changes behavior before the costs actually change.

Where self-correction fails

Now consider insulin. Three manufacturers control roughly 90% of the U.S. insulin supply. Over the past two decades, insulin prices rose by approximately 600% - not because the medication changed or became more expensive to produce, but because the manufacturers and the pharmacy benefit managers in the supply chain could raise prices without losing customers. Diabetic patients cannot wait. They cannot switch to a cheaper substitute. They pay, or they get sick, or they ration their doses and risk their lives.

The theoretical market correction - new competitors entering, generic manufacturers undercutting - was actively prevented through patent strategies, exclusivity agreements, and formulary deals that blocked lower-cost alternatives from reaching patients. The demand-side discipline did not exist. The threat of competition was neutralized. Prices went where the math allowed, unconstrained by any market force.

Housing follows the same pattern in high-demand markets. When a city has more people who need housing than there are units available, landlords do not need to compete on price. They raise rents until demand clears - meaning until some portion of renters simply cannot afford to live there and leave. The people left behind pay whatever the market requires, because the alternative is homelessness.

The supply-side solution

In an inelastic markets, the only way to bring prices down is to increase supply to the point where demand is genuinely satisfied. With ten apartments and ten renters, rents are stable. Remove one renter and the apartment owner with an empty unit drops their price - some money is better than no money, and the race to fill vacancies begins. Add one more renter and the one person without a place bids up prices for everyone else.

The math is straightforward: sufficient supply creates vacancy; vacancy creates competition among suppliers; competition disciplines prices. Insufficient supply creates scarcity; scarcity gives pricing power to suppliers; pricing power is exercised. There is no version of this where high demand and restricted supply produces affordable prices.

The supply principle: In an inelastic market, the only reliable path to lower prices is increased supply at sufficient scale to genuinely satisfy demand. Price controls suppress symptoms; supply expansion treats the cause.

Why supply does not automatically expand

If increased supply solves the problem, why does supply not increase on its own? The answer is that the parties who control supply in inelastic markets often benefit from keeping it constrained. A housing developer can build more units and accept a lower margin per unit while earning more total revenue. But existing landlords benefit directly from scarcity - their existing units appreciate in value and command higher rents when supply is tight. The incentive to restrict and the incentive to expand point in opposite directions, and the parties with the most political leverage are typically those who already own the assets.

There is currently no mechanism that overrides this dynamic in housing. Zoning laws, permitting processes, neighborhood opposition, and planning delays all operate in an environment where the political weight of existing property owners typically exceeds the political weight of future residents who do not yet exist and cannot yet vote.

How SSOL creates supply-side pressure

SSOL introduces a new actor into this dynamic: the large employer whose wage obligations are directly and quantifiably tied to the cost of housing in their market.

When SSOL is implemented, every $100 per month increase in the local rent benchmark increases the SSOL wage for every employer in the commute radius. A company with 1,000 employees at or near the wage floor sees its annual labor cost increase by $1.2 million for every $100/month rent increase. That is not an abstraction - it is a balance sheet line that the CFO reviews every quarter.

That employer now has a direct financial interest in housing supply that currently does not exist. They are not a developer and may not want to become one. But they do want lower housing costs, and they have the political standing to show up at a planning commission meeting with a very different message than a developer seeking a permit. Their message is: the housing shortage is raising our labor costs every quarter, and if this market does not resolve it, we are running the math on relocation to a market that has.

Communities that restrict housing supply choose a higher SSOL for employers in their jurisdiction. That choice has a price tag that is visible, quarterly, and quantified. The NIMBYism that currently operates as a costless political preference becomes an explicit economic decision with documented financial consequences for the largest employers in the area.

How smaller employers participate

The direct version of this mechanism works for large employers because they have enough individual market presence to move a political conversation on their own. A company with 5,000 employees in a single market showing up at a planning commission is a different conversation than a company with 30.

Small and mid-size employers do not have that individual leverage. But they do not need it, because they already operate collectively through the same organizations they use for every other shared economic interest. Chambers of commerce, industry trade groups, employer cooperatives, and business associations exist precisely to give smaller employers the collective weight they lack individually. Under SSOL, those organizations gain a specific, quantified, quarterly reason to pressure inelastic market costs on behalf of their members - because every member's wage floor moves with those costs.

The mechanism is the same. A chamber of commerce representing five hundred small businesses in a region, all of whose labor costs rise every time local housing prices climb, has more political standing on housing supply than any one of those businesses does alone. The SSOL calculation gives that argument a number. The organizations to make it already exist.

The same logic applies across all SSOL components

Housing is the most visible example, but the mechanism operates across every inelastic markets in the SSOL calculation:

In each case, SSOL does not dictate a solution. It prices the problem and aligns the financial incentive of those with market leverage with the need to solve it. The solutions emerge from whoever has the most to gain from finding them.
