The evidence for the United States points to balanced growth despite falling investment-good prices and an elasticity of substitution between capital and labor less than one. This is inconsistent with the Uzawa Growth Theorem. We extend Uzawa's theorem to show that the introduction of human...

We study the politics of intergenerational redistribution in an overlapping generations model with short-lived governments. The successive governmentsþwho care about the welfare of the currently living generations and possibly about campaign contributionsþare unable to pre-commit the future...

This paper develops a simple approximation method for computing equilibrium portfolios in dynamic general equilibrium open economy macro models. The method is widely applicable, simple to implement, and gives analytical solutions for equilibrium portfolio positions in any combination or types of...

We investigate the choice of exchange-rate regime fixed or floating in a dynamic, intertemporal general equilibrium framework. Our framework extends Devereux and Engel (1998) by investigating the implications of internationalized production. We examine the role of price-setting -- whether prices...

We construct a model of growth based on endogenous technological change in a small, open economy. Entrepreneurs develop new intermediate products whenever the present value of potential profits exceeds the cost of R&D. Diversity of intermediates contributes to total factor productivity in the...

Recent macroeconomic experience has drawn attention to the importance of interdependence among countries through financial markets and institutions, independently of traditional trade linkages. This paper develops a model of the international transmission of shocks due to interdependent...

A basic prediction of effcient risk-sharing is that relative consumption growth rates across countries or regions should be positively related to real exchange rate growth rates across the same areas. We investigate this hypothesis, employing a newly constructed multi-country and multi-regional...

With integrated trade and financial markets, a collapse in aggregate demand in a large country can cause 'natural real interest rates' to fall below zero in all countries, giving rise to a global 'liquidity trap'. This paper explores the policy choices that maximize the joint welfare of all...

Jagdish Bhagwati coined the phrase quid pro quo foreign investment to describe international investments made in anticipation of host country trade policy and perhaps with the intention of defusing a protectionist threat. We apply Bhagwati's notion to situations where (i) foreign investment is...

The 'International Policy Trilemma' refers to the constraint on independent monetary policy that is forced on a country which remains open to international financial markets and simultaneously pursues an exchange rate target. This paper shows that, in a global economy with open financial...
