The impact of new housing supply on the distribution of rents

I estimate the impact of new housing supply on the local rent distribution, exploiting delays in housing completions caused by weather shocks. A 1% increase in new supply (i) lowers average rents by 0.19%, (ii) effectively reduces rents of lower-quality units, and (iii) disproportionately increases the number of second-hand units available for rent. Moreover, the impact on rents is equally strong in high-demand markets. Employing a quantitative model, I explain these results by second-hand supply: New supply triggers moving chains that free up units in all market segments. The estimate translates into a short-run demand price elasticity of −0.025.
