<p>Using the large-scale public housing program in Singapore as a quasi-natural experiment, we demonstrate that affordable public housing enhances intergenerational mobility for families of lower socioeconomic status. By matching 147,560 parent–child pairs with their housing transaction prices in 1995–2018, we identify three intergenerational mobility patterns in housing consumption: upward mobility among children from families in the bottom 50 percentile ranks, high persistence among children born to parents in the top 20 housing ranks, and downward mobility among the rest. We use the public housing supply shock to construct a difference-in-differences strategy, finding that children whose parents benefited from the affordable public housing program have a 9.5% higher likelihood of surpassing their parents in terms of housing status. Our results provide insight into a new pathway to enhance intergenerational mobility through an affordable housing program, which alleviates housing consumption budget constraints and enables parents to invest more in children’s human capital.</p>
