We introduce public debt in a Ramsey model with heterogenous agents and a public spending externality a ecting utility which is nanced by income tax and public debt. We show that public debt considered as a xed portion of GDP can have a stabilizing or destabilizing e ect depending on some...

We address the issues of existence of Ramsey equilibrium under bor- rowing constraints and occurrence of rational bubbles. First, we consider a time-truncated economy. Since the feasible allo- cations sets of our economy are uniformly bounded, we prove that there exists an equilibrium in a...

We introduce public spending, financed through income taxation, in the Ramsey model with heterogeneous agents. Public spending as a source of welfare generates more complex dynamics. In contrast to previous contributions focusing on similar models but with wasteful public spending, limit cycles...

We develop a two-period trade-theoretic model for a recipient country with credit constraints and develop a necessary and sufficient condition for replacing foreign aid by credit to be welfare improving.

Earlier research have concluded that high house prices, relative to household income and wealth, and a tax on imputed rent are the most important causes of a countries low ownership rate. Given these findings, it is challenging to apply a similar analysis to a housing market characterized by...

We study the existence of equilibrium and rational bubbles in a Ramsey model with heterogeneous agents, borrowing constraints and endogenous labor. Applying a nonstandard fixed-point theorem by Gale and Mas-Colell's (1975), we prove the existence of equilibrium in a time-truncated bounded...
