Do French low‐income GPs choose to work less?
利用1993-2004年法国自雇全科医生面板数据，通过分析其对正负需求冲击的反应，发现低收入全科医生不因需求增加而增加工作，却因需求减少而减少工作，表明其低收入源于强烈的休闲偏好。
In France, a significant number of General Practitioners (GPs) earn less than 1.5 times the French minimum salary. Using a representative panel of self-employed GPs over the years 1993-2004, this paper tests whether these low-income GPs choose to work less than all other GPs or whether they are constrained to do so. The test is based on measuring reactions to positive and negative demand shocks. As low-income GPs do not increase activity in response to a positive demand shock but decrease activity in response to a negative demand shock, it appears that their low-income status is attributable to a strong preference for leisure.
