We study the impact of social capital in both simple theoretical and em- pirical model with the main assumption is the price of physical capital is a decreasing function of social capital.

We address the fundamental issues of existence and efficiency of an equilibrium in a Ramsey model with many agents, where agents have heterogenous discounting, elastic labor supply and face borrowing con- straints. The existence of rational bubbles is also tackled. In the first part, we prove...
