Since 1980, the aggregate income of oil-exporting countries relative to that of oil- poor countries has been remarkably constant despite structural gaps in productivity growth rates. This stylized fact is analyzed in a two-country model where resource- poor (Home) and resource-rich (Foreign)...

The theory of welfare accounting shows that comprehensive measures of net investment can be used to test whether an economy is following unsustainable paths of consumption. However, the notion of net investment used in most applied studies rules out technological progress and terms-of-trade...

We study the incentives of selfish governments to tax tradable primary inputs un- der asymmetric trade. Using an empirically-consistent model of endogenous growth, we obtain explicit links between persistent gaps in productivity growth and the observed tendency of resource-exporting (importing)...

We build a two-country model of endogenous growth to study the welfare effects of taxes on tradable primary inputs when countries engage in asymmetric trade. We obtain explicit links between persistent gaps in productivity growth and the incentives of resource exporting (importing) countries to...

Green accounting theories have shown that negative genuine savings at some point in time imply unsustainability. Consequently, recent studies advocate the use of the genuine savings measure for empirical testing: a negative index implies sustainability be rejected. This criterion is not...

This paper studies the effects of distortionary taxes and public in- vestment in an endogenous growth OLG model with knowledge trans- mission. Fiscal policy affects growth in two respects: .rst, work time reacts to variations of prospective tax rates and modi.es knowledge formation; second,...

The interaction between habit formation and pollution-type ex- ternalities modifies the social optimum through discount effects and elasticity effects. If the substitution elasticity does not exceed unity, both effects reduce optimal consumption and capital in the long run, and the optimal...

We analyze a multi-sector growth model with directed technical change where man-made capital and exhaustible resources are essen- tial for production. The relative profitability of factor-specific inno- vations endogenously determines whether technical progress will be capital- or...

This paper analyzes international status seeking in a two-country model of endogenous growth: utility of agents in developing countries is affected by con- sumption gaps with the average consumer in advanced economies. By distorting terms of trade, status seeking: (i) may compensate for...

This paper analyzes overlapping-generations models where natural capital is owned by selfish agents. Transfers in favor of young agents reduce the rate of depletion and increase output growth. It is shown that intergenerational transfers may be preferred to laissez-faire by an indefinite...
