We compare the performance of the perturbation-based (local) portfolio solution method of Devereux and Sutherland (2010a, 2011) with a global solution method. We find that the local method performs very well when the model is designed to capture stylized macroeconomic facts and countries/agents...

We propose a new welfare criterion that allows us to rank alternative financial market structures in the presence of belief heterogeneity. We analyze economies with complete and incomplete financial markets and/or restricted trading possibilities in the form of borrowing limits or transaction...

We study an economy in which two types of agents have diverse beliefs about the law of motion for an exogenous endowment. One type knows the true law of motion, and the other learns about it via Bayes's theorem. Financial markets are incomplete, the only traded asset being a risk-free bond....

Substantial progress has been made in recent years in integrating optimal portfolios into (open macro) general equilibrium models using standard local approximation (perturbation) methods. We compare these perturbation-based portfolio solution methods with a global portfolio solution method to...

I solve for the optimal (state-contingent) contract and find that moral hazard friction is sufficient to explain capital outflows in low output states –- a defining feature of the emerging markets business cycles. On the other hand, the model that also includes limited enforcement is...

We develop an envelope condition method (ECM) for dynamic programming problems –a tractable alternative to expensive conventional value function iteration. ECM has two novel features: First, to reduce the cost, ECM replaces expensive backward iteration on Bellman equation with relatively...
