In a dynamic general equilibrium model we explictly consider the relationship between the product attributes ’durability’ and ’recyclability’. Both efficiency and sustainability aspects are taken into account. It turns out (a) that durability may be inefficient even in a perfectly competitive economy in which environmental externalities are absent, (b) that in case where markets for product des...

This paper examines information sharing between governments in an optimal taxation framework. We present a taxonomy of alternative systems of international capital income taxation and characterize the choice of tax rates and information exchange. The model reproduces the conclusion of the previous literature that integration of international capital markets may lead to the under-provision of pu...

We utilise repeated cross sections of micro data from several countries, available from the Luxembourg Income Study, LIS, to estimate labour supply elasticities, both at the intensive and extensive margin. The benefit of the data is that it spans over four decades and includes a large number of tax reform episodes, with tax rate variation arising both from cross-sectional and country-level diff...

In this article, the joint use of an income tax and public provision of education as instruments to achieve the government’s distributional objectives is considered. Individuals differ in innate labour productivity and in aptitude to acquire skills through education. Actual labour productivity depends on both innate skill and the amount of education received. Using a generalized version of the ...

We assessed the uptake rates of nitrate by the scleractinian coral Stylophora pistillata by following 15N from seawater into the coral tissue. Two sets of corals were first prepared, with ‘‘nitrate-enriched’’ corals grown in 5 mmol L21 NO and control corals grown in #1 mmol L21 NO . Uptake rates at 0.3 and 3 mmol L21 [15N]NO 2 2 2 3 3 3 were then measured. Most of the %15N enrichment occurred i...

In an integrated dynamic general equilibrium model of the economy and the ecosystem humans and other species compete for land and prey biomass. Each submodel exhibits a price-driven competitive allocation mechanism, and the endogenously determined habitat is either openly accessible or privately owned. In both scenarios specific corrective taxes or subsidies are needed to internalize ecosystem ...

We compare the effects of taxes and quotas for an environmental problem where the regulator and polluter have asymmetric information about abatement costs, and environmental damage depends on pollution stock. An increase in the slope of the marginal abatement cost curve, or a decrease in the slope of the marginal damage curve, favors taxes. An increase in the discount rate or the stock decay ra...

We show that in models in which labor services are supplied jointly with human capital, the Chamley and Judd result on zero capital income taxation in the limit extends to labor taxes as long as accumulation technologies are constant returns to scale. Moreover, for a class of widely used preferences, consumption taxes are zero in the limit as well. However, we show by the construction of two ex...

This paper explores the rationale for unemployment beneÞts as a complement to optimal non-linear income taxation. High-skilled workers and low-skilled workers face different exogenous risks of being unemployed. As long as the low-skilled workers face a higher unemployment risk, we Þnd that there is a case for over-insuring the lowskilled, hence the unemployment beneÞts of the low-skilled should...
