Tax Subsidies and Household Saving: Evidence from Canada
利用加拿大取消注册购房储蓄计划（RHOSP）这一外生政策变化，发现该税收补贴对家庭储蓄有显著促进作用：每1美元补贴分别带来56-93美分的新增家庭储蓄和20-57美分的新增国民储蓄。
Targeted tax-based saving incentives can be a powerful tool for promoting household and national saving. This study examines the effect of the cancellation of the Registered Home Ownership Savings Plan (RHOSP), a Canadian tax-subsidized saving program, on household saving. The cancellation provides exogenous variation in eligibility for the subsidy that is uncorrelated with householdspecific heterogeneity in saving behavior. The empirical analysis suggests that the subsidy had a substantial impact on saving: each dollar contributed to the program represented 56-93 and 20-57 cents of new household and national saving, respectively.
