Breaking bad habits by education - smoking dynamics among Swedish women
研究瑞典女性吸烟行为，发现教育水平越高，过去吸烟对当前是否吸烟的影响越小，即高学历者状态依赖更弱，但教育对吸烟量无类似影响。
In a dynamic Two-Part Model (2 PM), we find the effect of previous smoking on the participation decision to be decreasing with education among Swedish women, i.e. more educated are less state dependent. However, we do not find an analogous effect of education on the conditional intensity of consumption.
