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.

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...

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...

This thesis deals with a number of different topics in the field of international macroeconomics. It proposes theoretical models of the open economy to think about and analyze questions such as the effects of financial globalization, countries' external adjustment mechanism, international...

How much additional tax revenue can the government generate by increasing labor income taxes? In this paper we provide a quantitative answer to this question, and study the importance of the progressivity of the tax schedule for the ability of the government to generate tax revenues. We develop...

Americans work more than Europeans. Using micro data from the U.S. and 17 European countries, we study the contributions from demographic subgroups to these aggregate level dierences. We document that women are typically the largest contributors to the discrepancy in work hours. We also document...

The recent public debt crisis in most developed economies implies an urgent need for increasing tax revenues or cutting government spending. In this paper we study the importance of household heterogeneity and the progressivity of the labor income tax schedule for the ability of the government...
