This paper constructs a two-country stochastic growth model in which neutraland investment-specic technology shocks are nonstationary but cointegrated acrosseconomies. It uses this model to interpret data showing that while real investmenthas grown faster than real consumption in the United...

We construct and estimate a unified model combining three of the main sources of cross-country income disparities:[...]

This paper provides a unified theory of the economic and demographic transition. Individualsmake optimal decisions about fertility, education of their children and the type and intensity ofthe investments in their own education. These decisions are affected by different dimensionsof mortality...

In an inuential article Tornell and Lane (1999) considered an economy populatedby multiple powerful groups in which property rights in the formal sectorof production are not protected. They obtained conditions under which thegroups appropriate output from the formal sector in order to invest it...

In this paper, I present a theory of dynamic economic growth, business cycles, and asset pricing that integrates (1) Marx's idea (and emphasized by Klein) of a two-class heterogeneity of the ownership structure of physical capital and human capital in a capitalist society, (2) Keynes' idea of...

This paper studies the Cass-Koopmans-Ramsey model of optimal economic growth with a representative agent whose preferences for consumption can be gradually varied between the standard CES case and Kahneman and Tversky's prospect utility. The numerical analysis of a specific parametrization shows...

We compare the optimal capital stock accumulation in a classical Ramsey model with production shocks for a risk neutral expected utility maximizer and a loss averse prospect theory maximizer. It is shown that in the expected utility case the capital stock is on average the same as in the...

The aim of this paper is to account for both the short-run uctuations and thevery-long run transformations induced by technological change in analysing long-rungrowth patterns. The paper investigates the possible imprint left by short-run uctuationson the long run dynamics by aecting the...

This paper introduces a democratic voting process into an OLG economyin order to analyze the effects of a rising old-age dependency ratio on the composition ofgovernment spending and endogenous economic growth. Forward-looking agents vote eachperiod on the public policy mix between productive...

In a neoclassical economy with endogenous capital- and labor-augmentingtechnical change the steady-state growth rate of output per worker is shown to increasein the elasticity of substitution between capital and labor. This conrms theassessment of Klump and de La Grandville (2000) that the...
