*We discuss the 2 equilibrium concepts which yield a Pareto optimal allocation on a public goods game; Lindahl equilibrium and Kantian equilibrium. Kantian equilibrium is based on the universal ethical codes of conduct, whereas Lindahl equilibrium is defined by the personalized prices of public goods. First, we prove the existence of a Lindahl equilibrium in a general public goods framework where the action of each player has a heterogeneous positive externality, and where the consumer may consume a different amount of public good. Second, we explore how to construct a Kantian equilibrium from the Lindahl equilibrium of the auxiliary game, and to compute a function which represents the moral equivalent actions between players.

**In France, the gender wage gap for the 20% of the workforce living in the denser locations is 22% lower than that for those living in the bottom 20% of the density distribution, indicating that women benefit more from density than men. This paper explores the importance of geographical location for understanding the gender wage gap. Following the recent literature on economic geography that takes into account the endogeneity of location, we estimate the difference in the returns to urban density across genders. Results show that the elasticity of the wage premium increases with density for both men and women, with a significantly higher female urban wage premium. We consider different mechanisms to explain this pattern, such as the difference in returns to experience, the importance of the spatial dimension and the childcare facilities.
