We introduce heterogeneity in investors’ ability to borrow from collateral in a Kiyotaki–Moore style macro model, calibrated to the quintiles of the leverage-ratio distribution of US non-financial firms. Financial amplification intensifies, because of stronger asset price reactions of highly...

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...

TWe allow for heterogeneity in investors' ability to borrow from collateral in a Kiyotaki-Moore style macro model. We calibrate the model to match the quintiles of the distri- bution of leverage ratios of US non-financial firms. We show that financial amplification of the model with...

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...

Using a stylized two period model we obtain portfolio solutions from two solution approaches that belong to the class of local approximation methods – the approach of Judd and Guu (2001, hereafter ’JG’) and the approach of Devereux and Sutherland (2010, 2011, hereafter ’DS’) – and...

Using a stylized two-period model we compare portfolio solutions from two local solution approaches - the approach of Judd and Guu (2001) and the approach of Devereux and Sutherland (2010, 2011) - with the true nonlinear portfolio solution.

Differences in financial systems are often named as a prime candidate for the current state of global imbalances. This paper focuses on cross-country heterogeneity in access to international financial markets that derives from the presence of capital controls and argues that the process of...
