Time Preferences Across Language Groups: Evidence on Intertemporal Choices from the Swiss Language Border
研究瑞士双语城市中法语和德语使用者的时间偏好，发现法语群体比德语群体更缺乏耐心，尤其在涉及当前支付时差异显著，并量化了现时偏向和长期贴现因子的差异。
Abstract Differences in patience across language groups have recently received increased attention in the literature. We provide evidence on this issue by measuring time preferences of French and German speakers from a bilingual municipality in Switzerland where institutions are shared and socio-economic conditions are very similar across the two language groups. We find that French speakers are significantly more impatient than German speakers, and differences are particularly pronounced when payments in the present are involved. Estimates of preference parameters of a quasi-hyperbolic discounting model suggest significant differences in both present bias (β) and the long-run discount factor (δ) across language groups.
