Declining discount rates in Singapore's market for privately developed apartments
利用新加坡私人开发公寓产权期限的准实验差异，估计出随时间递减的贴现率，到第400年降至0.5-1.5%年化，表明家庭并未完全贴现数百年后的收益，对评估气候变化投资有参考价值。
Summary Singapore's market for new privately developed apartments exhibits wide quasi‐experimental variation in ownership tenure. We develop an empirical model in which prices are decomposed into the utility of housing services and a factor that shifts with asset tenure and the discount rate schedule, which we discipline to vary smoothly over time. We estimate discount rates that decline over time and, to accommodate the observed price differences, fall to 0.5–1.5% p.a. by year 400. The finding that households making sizable transactions do not entirely discount benefits accruing centuries from today is relevant, with the appropriate risk adjustment, for evaluating climate‐change investments.
