This chapter studies the e¤ect of consumption externalities on stability properties of a Ramsey model with heterogeneous agents and borrowing constraints. Agents di¤er in their initial wealth, felicity functions and discount factors. For simplicity, heterogeneity is reduced to two groups....

This paper studies the e¤ect of consumption externalities in a Ramsey model with heterogeneous agents and borrowing constraints. We consider two types of agents who di¤er in their initial wealth and discount factors. Further, we leave open the possibility of increase in consumption of one...

This chapter examines the e¤ect of leisure externalities on the ap- pearance of local indeterminacy in a two-period overlapping generations economy with capital accumulation. Households work and consume in both periods of their life. Labor supply is elastic for young while inelastic for adult....

We consider a Ramsey model with heterogeneous agents and borrow- ing constraint. Heterogeneity across agents stems from di¤erent initial capital endowment, labor supply, felicity function and discount rate. For simplicity, heterogeneity is reduced to only two groups of agents where they are...

In this paper, we study the effects of collaterals on business cycles and growth in monetary economies with credit market imperfections. We consider an endogenous growth model with a partial cash-in-advance constraint and inelastic labor supply. We assume that the share of consumption purchases...
