An example of asking generative AI to examine housing affordability problems via the critical realism lens: for Housing Studies students
Suggest 3 main housing affordability problems facing the
Hong Kong middle-class families in 2026, based on the Hong Kong public
media-reported issues.
Three housing
affordability problems stand out for Hong Kong middle-class families in 2026:
private home prices are still far beyond household incomes, rents are consuming
a very large share of pay, and many “sandwich class” households are stuck
between not qualifying for public housing and not being able to afford private
housing.
1) Private home ownership is still out of
reach
Public reporting
in 2026 says a mid-sized private flat can cost more than 18 years of an average
household’s combined income, showing that ownership remains structurally
unaffordable even after some price declines. Reports also note that Hong Kong
remains one of Asia’s least attainable housing markets, with a price-to-income
ratio far above the common affordability benchmark. For middle-class families,
this means saving for a down payment and meeting mortgage requirements is still
extremely difficult.
2) Rents are rising faster than incomes
Media coverage
shows that average rents now absorb around 72% of median monthly income, which
leaves little room for family spending or savings. This is especially painful
for middle-class households that cannot buy yet also do not qualify for
subsidised housing, so they remain exposed to the rental market. The result is
a squeeze on day-to-day living standards and on the ability to save for a
future home.
3) The middle class is squeezed out of policy
support
A recurring issue
in Hong Kong media is the “sandwich class” problem: many middle-income families
earn too much for public housing but too little to buy privately without severe
hardship. Public reports also describe strict income and asset tests, which
make it hard for families to move up from subsidised housing into private
ownership. That leaves them in a long-term affordability trap rather than a
clear path to stable housing.
A concise way to
frame it in your dissertation or notes is: price, rent, and policy-gap.
Suggest 3 causal mechanisms that produce the three
problems raised above from the critical realism (notably the real layer)'s
perspective.
From a critical realism perspective, the three problems
can be explained by three deeper real-layer mechanisms that generate the
visible affordability crisis.
1) Land-supply
constraint mechanism
Hong Kong’s highly
constrained land supply, together with planning and development bottlenecks,
pushes the housing system toward chronic scarcity. In critical realist terms,
this is a generative mechanism because it continuously reproduces high prices
and rents even when demand weakens temporarily. This mechanism helps explain
both the unaffordable purchase market and the persistent rent burden on
middle-class families.
2) Asset-speculation
mechanism
Housing in Hong Kong
functions strongly as a financial asset, so price formation is driven not only
by shelter need but also by investment demand, capital flows, and expectations
of future gains. This mechanism inflates purchase prices faster than household
incomes and also supports landlord pricing power in the rental market. In other
words, homes are treated as stores of value, which makes the market
structurally hostile to ordinary wage earners.
3) Stratified-tenure
exclusion mechanism
The housing system is
segmented into private, subsidised, and public sectors, but middle-income
households often fall between the eligibility thresholds. That creates a
mechanism of exclusion: they are not poor enough for public assistance and not
wealthy enough for market entry, so they remain trapped in expensive renting or
prolonged saving. This also reproduces the “sandwich class” problem and
explains why housing stress persists across generations rather than being
resolved by income growth alone.
How the mechanisms map
·
Unaffordable ownership is mainly produced
by land scarcity plus speculation.
·
Rising rent pressure is mainly produced
by asset-driven landlord pricing within a scarce market.
·
Policy exclusion of middle-class families is mainly produced
by tenure stratification and eligibility gaps.
If you are writing this
in dissertation style, you can frame them as: structural scarcity, financialization, and tenure stratification.
Describe four main characteristics of causal mechanisms
in critical realism.
Four main characteristics of causal
mechanisms in critical realism are as follows.
1) Generative, not just correlational
Causal mechanisms
do not merely sit beside repeated patterns; they generate events by producing
outcomes when activated in the right conditions. This is why critical realism
distinguishes causal explanation from simple statistical association.
2) Real but often unobservable
Mechanisms belong
to the real layer: they exist whether or not we directly
observe their effects. Researchers usually infer them indirectly from patterns,
events, and context rather than seeing them straight away.
3) Conditional and contingent
A mechanism may
have causal power yet fail to produce an outcome if other mechanisms intervene
or if the conditions are not favourable. In critical realism, causation is
therefore not deterministic in a simple one-cause-one-effect sense.
4) Context-dependent and layered
Mechanisms operate
in open systems, so their effects depend on interactions across different
levels and with other mechanisms. This means the same mechanism can produce
different outcomes in different social or institutional settings.
A compact
dissertation-ready formulation is: causal mechanisms in critical realism
are generative, real, contingent, and context-dependent.
