Marijuana on Main Street? Estimating Demand in Markets with Limited Access
研究大麻合法化对需求的影响，发现传统需求估计有偏，若合法化，30岁以下人群使用量增加28%，平均增加48%，税收政策可有效抑制使用。
Marijuana is the most common illicit drug with vocal advocates for legalization. Among other things, legalization would increase access and remove the stigma of illegality. Our model disentangles the role of access from preferences and shows that selection into access is not random. We find that traditional demand estimates are biased resulting in incorrect policy conclusions. If marijuana were legalized, those under 30 would see modest increases in use of 28 percent, while on average use would increase by 48 percent (to 19.4 percent). Tax policies are effective at curbing use, where Australia could raise AU$1 billion (and the United States US$12 billion).
