Supply, Demand, and Government Policies

Economists function as policy analysts and advisers by applying theoretical frameworks to improve real-world outcomes.
Policies can have unintended or unanticipated results that modify private market outcomes, leading to the imposition of price controls and taxes.

Scenario: The Muffin Buyers’ Association advocates for a price ceiling.
- Price Ceiling Set at $5:
- Outcome: Non-binding as equilibrium price ($3) is below $5.
- Quantity demanded (Qd) = 15.
- Quantity supplied (Qs) = 15.
- Price Ceiling Set at $2:
- Outcome: Binding; the market price cannot exceed $2.
- Qd = 18 muffins, Qs = 10 muffins.
- Resulting shortage = 8 muffins (Qd - Qs).

Price ceilings do not necessarily lower the cost for consumers but can lead to:
- Queuing: A shift from financial costs to time costs as consumers wait for goods.
- Secondary Markets: Scalpers may appear in a market where prices are artificially low to benefit from selling goods at a higher price.
- Bypass Restrictions: Example includes bundling services, such as overnight parking, to avoid control restrictions.

Example: Local ordinances have shown a mixed impact on affordable housing.
- Rent controls can lead to a reduced quantity of housing units as owners find less incentive to maintain or add rental properties.
- Potential deterioration in the quality of existing rental housing units.
- Results in wasteful demand where current tenants hold onto controlled apartments instead of moving.

The 2010s recorded the lowest number of housing starts in history with a significant decline in new privately-owned housing units.
Analysis shows that institutional investors play a minor role overall in housing but draw attention because of localized concentration in major markets.

Effective strategies to improve housing affordability include:
- Streamlining building permit processes.
- Changing zoning laws to support higher density housing developments.
- Encouraging investments in construction to increase supply.

A price floor can lead to a surplus in the market.
- Not Binding: A price floor set below equilibrium has no effect on the market.
- Binding: A price floor above equilibrium results in a surplus because the quantity supplied exceeds the quantity demanded.

Scenario by Muffin Sellers’ Association:
- A price floor of $1:
- Outcome: Not binding since equilibrium price ($3) is above $1.
- A price floor of $4:
- Outcome: Binding, leading to higher prices with a corresponding surplus of muffins (Qs=20, Qd=12, Surplus=8).

Minimum wage is a commonly debated price floor in labor markets:
- The current US federal minimum wage is $7.25 per hour with variations across states.
- Increase debates arise around potential unemployment impacts among low-skilled workers, particularly teenagers.
- Short-run estimates suggest a 10% rise in minimum wage could reduce employment by 1-3% among teenagers.
- Long-run impacts are uncertain, and higher elasticity suggests larger displacement effects over time.

Advocates:
- Argue it is a humane solution to raise living standards among low-wage earners.
Opponents:
- Critique potential job losses and market inefficiencies caused by poorly targeted wage policies.
- Propose alternatives like the Earned Income Tax Credit (EITC) for more effective poverty alleviation.

Economists generally oppose price controls, arguing they disrupt the natural balance of supply and demand.
Instead, alternative measures such as direct subsidies or tax credits may provide less harmful support to vulnerable populations.

Tax incidence refers to how the burden of taxation is shared between buyers and sellers.
- When a tax is levied, the market equilibrium changes, causing the equilibrium quantity to decrease.
- The determination of tax incidence is more related to the price elasticities of supply and demand than to the statutory imposition of the tax.
- Buyers and sellers within a market share the burden based on their relative elasticities: the less elastic side bears a greater share of the burden.
