We use the Euler equation to put forward a back-on-the-envelope rule for the global carbon tax based on a two-box carbon cycle with temperature lag, and a constant elasticity of marginal damages with respect to GDP. This tax falls with time impatience and intergenerational inequality aversion...

Climate change must deal with two market failures, global warming and learning by doing in renewable use. The social optimum requires an aggressive renewables subsidy in the near term and a gradually rising carbon tax which falls in long run. As a result, more renewables are used relative to...

Unilateral second-best carbon taxes are analysed in a two-period, two-country model with international trade in final goods, oil and bonds. Acceleration of global warming resulting from a future carbon tax is large if the price elasticities of oil demand are large and that of oil supply is...

Many countries have failed to use natural resource wealth to promote growth and development. They have been damaged by volatility of revenues, have failed to save a sufficiently high proportion of their resource revenues and failed to make high return investments to support diversification of...

We investigate the Hartwick rule for saving of a nation necessary to sustain a constant level of private consumption for a small open economy with an exhaustible stock of natural resources. The amount by which a country saves and invests less than the marginal resource rents equals the expected...

This paper investigates the implications of budgetary policies for consumption and economic growth. We present a model that combines the Arrow-Romer endogenous growth model with the Blanchard-Yaari overlapping-generations model. We show that a rise in government debt, financed by lump-sum taxes,...

This paper analyses some of the implications of the proposals of the Delors Committee for monetary and fiscal policies in Europe. The merits of an independent ESCB are discussed. We offer four reasons why, in the absence of European coordination of budgetary policies, the size of the public...

The political distortions in public investment projects are investigated within the context of a bipartisan political economy framework. The role of scrapping and modifying projects of previous governments receives special attention. The party in government has an incentive to overspend on large...

We investigate the effects of budgetary policies on growth rates, external debt, real interest rates and the stock market valuation of capital in a two-country, overlapping-generations model of endogenous growth. A worldwide rise in the public debt/GDP ratio, or the share of government...

Many resource-rich countries have poor economic performance and suffer from negative genuine saving rates, especially if they have many rival factions and badly functioning legal systems. We attempt to shed light on these stylized facts by analyzing a power struggle about the control of natural...
