We set up an endogenous growth model in which the efficiency of both capital and fossil energy can be improved, whereas the efficiency of one alternative energy source is limited. With capital and energy as complements, there exist two steady states: one stagnant where energy is fully derived...

How do markets economize on scarce natural resources? With an application to fossil energy, we emphasize technological change aimed at saving on the scarce resource. We develop quantitative macroeconomic theory as a tool for interpreting the past and thinking about the future. We argue, first,...

This paper analyzes the interaction between oil prices and macroeconomic outcomes by incorporating oil as an input in production alongside a precautionary motive for holding oil in a real-business-cycle model. The driving forces are factor-specific technology shocks and supply shocks that can be...

This paper discusses how price stability can be defined and how price stability can be maintained in practice. Some lessons for the Eurosystem are also considered. With regard to defining price stability, the choice between price-level stability and low (including zero) inflation and the...

We construct an integrated assessment model with multiple energy sources - two fossil fuels and "green energy" - and use it to evaluate ranges of plausible estimates for the climate sensitivity as well as for the sensitivity of the economy to climate change. Rather than focusing on uncertainty...

To what extent is the international business cycle affected by the fact that an essential input (oil) is traded on the world market? We quantify the contribution of oil by setting up a model with separate shocks to efficiencies of capital/labor and oil, as well as global shocks to the oil...

What are the real and nominal implications of a green transition to a state with sustainable energy production, and how should monetary policy react during such transition? Using a New-Keynesian model with an energy and a goods sector, we show that a green transition requires the relative price...

This paper specifies a new convenient algorithm to construct policy projections conditional on alternative anticipated policy-rate paths in linearized dynamic stochastic general equilibrium (DSGE) models, such as Ramses, the Riksbank's main DSGE model. Such projections with anticipated...

Optimal taxes for Europe and the U.S. are derived in a realistically calibrated model in which agents buy consumption goods and services and use home capital and labor to produce household services. The optimal tax rate on services is substantially lower than the tax rate on goods. Specifically,...

The purpose of the paper is to survey and discuss in ation targeting in the context of monetary policy rules. The paper provides a general conceptual discussion of monetary policy rules, attempts to clarify the essential characteristics of in ation targeting, compares in ation targeting to other...
