Employment in a one-industry town falls 20%. Through what mechanism does housing demand contract?
Correct Answer
B) Household formation and purchasing power shrink together
Why this is correct: Housing demand is derived from employment and household income. A 20% job loss reduces in-migration, household formation, and the purchasing power of remaining residents, contracting demand. Why the other choices are wrong: Construction costs may decline, but that's a supply factor. Physical deterioration is not directly accelerated by job loss. Interest rates are set by broader monetary policy, not local job changes. Exam tip: Jobs and income drive housing demand.
Why This Is the Correct Answer
Option B names both channels through which the shock reaches housing, which are the count of households and the purchasing power behind each one. Household formation falls as out-migration rises and as young workers postpone forming separate households, so the quantity of demand shrinks. Purchasing power falls with lost wages and tightened credit, so the price each remaining household can support also shrinks. Because demand for housing is derived from employment and income, this pairing is the direct and complete answer rather than one of several partial contributors.
Why the Other Options Are Wrong
Option A: Construction costs decline alongside wages
Construction costs are a supply-side variable, and even if local labor rates soften after layoffs, materials pricing is set regionally or nationally and would not move much. More to the point, a change in the cost of producing new housing does not explain why fewer people want housing. The option answers a question about supply when the stem asks about demand.
Option C: The housing stock physically deteriorates much faster
Buildings deteriorate at rates driven by age, construction quality, climate, and maintenance, none of which change the day employment falls. Deferred maintenance may increase over several years as owner incomes fall, but that is a slow secondary consequence rather than the mechanism by which demand contracts. The option confuses a possible later symptom with the cause.
Option D: Interest rates automatically rise in response
Mortgage interest rates are set in national capital markets by monetary policy and investor demand, and no single local labor market moves them. Local lenders may tighten underwriting standards in a weakening market, which is a credit availability effect rather than a rate effect, and it still is not automatic. The option assumes a feedback loop from local employment to interest rates that does not exist.
Jobs Bring Buyers
Housing demand is downstream of paychecks. Take away the paychecks and two things go at once: the number of households, because people leave or never form one, and the size of the check each remaining household can write. Everything else about a downturn is a consequence of those two.
How to use: For any question about a local economic shock, first ask whether the choice describes demand or supply. Then look for the answer naming households and income together, because a single-channel answer is usually incomplete.
Exam Tip
Sort every market analysis choice into demand or supply before evaluating it. Roughly half the distractors in this question type are true statements about the wrong side of the market.
Common Mistakes to Avoid
- -Answering with a supply-side factor such as construction cost when the question asks about demand
- -Continuing to apply a positive market conditions adjustment after the employment base has turned
- -Treating a one-employer town as stable because current occupancy and rents still look healthy
Concept Deep Dive
Analysis
This item asks for the transmission mechanism between an employment shock and housing demand, which is a market analysis question rather than a valuation calculation. Housing demand is derived demand: nobody wants a house for its own sake, they want it because they live and work somewhere, so demand traces back to jobs and the income jobs produce. In a one-industry town the export base is concentrated in a single employer or sector, so a twenty percent employment decline strikes the basic sector directly and then multiplies through the non-basic sector that served those workers. Two effects run in parallel: fewer households form or remain, because laid-off workers leave the area, delay independent living, or double up, and the households that stay have less income and less ability to qualify for financing. Together those reduce the number of buyers and renters and the price each can pay, which shows up as longer marketing times, rising vacancy, and softening rents and prices.
Background Knowledge
You need the concept of derived demand, meaning that real estate demand follows from the economic activity that occupies space, and the basic and non-basic split of an economic base with its employment multiplier. You should know the demand indicators used in market analysis, including population, household formation, household income, and employment by sector, and that concentration in one employer creates a stability risk regardless of current performance. You also need to recognize the supply-side variables, such as construction cost, permits, and inventory, so you can tell which side of the market a question is about.
Real-World Application
After a paper mill announces a shutdown in a small town, an appraiser reviewing recent sales sees listing inventory climbing, days on market lengthening, and two closed sales with seller concessions. The market analysis section documents the employment loss, the resulting migration and income effects, and concludes that market conditions are declining, which changes both the time adjustment and the exposure time estimate in the report.
