We study the optimal loan-to-value (LTV) ratio in a monetary general equilibrium model with heterogeneous agents, collateral default, production and a banking sector. We find that the welfare of the debtor is not monotonically increasing in the LTV ratio, i.e. tighter financing constraints can...

We present the optimal consumption and investment strategy for an investor, endowed with labor income, searching to maximize utility from consumption and terminal wealth when facing a binding capital constraint of a European (constraint on terminal wealth) or an American (constraint on the...

In this paper, we address the stability issue, stressing the role of labor supply, in a Ramsey model with heterogeneous households subject to borrowing constraints. Making labor supply endogenous leads us to prove the existence of two kinds of steady state : the one where everybody supplies...

A model that allows for inter vivos intergenerational transfers in a booming housing market is developed. The model is used to explain how transfers effect the first-time homebuyer’s consumption and housing decisions by alleviating borrowing constraints. The general implications of the model...
