This paper systematically examines the role of fiscal policy, trade and energy taxes on environmental quality in Europe using disaggregated data for 12 European countries over the 1995-2008 period. It uses a methodology that obtains estimates mostly free of time-varying omitted variable biases....

This paper develops a model that integrates the climate and the global economy---an integrated assessment model---with which different policy scenarios can be analyzed and compared. The model is a dynamic stochastic general-equilibrium setup with a continuum of regions. Thus, it is a full...

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...

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...

This paper proposes a new approach for modeling investor fear after rare disasters. The key element is to take into account that investors' information about fundamentals driving rare downward jumps in the dividend process is not perfect. Bayesian learning implies that beliefs about the...

This paper considers a general class of nonlinear rational-expectations models in which policymakers seek to maximize an objective function that may be household expected utility. We show how to derive a target criterion that is: (i) consistent with the model's structural equations, (ii) strong...

We model the motives for residents of a country to hold foreign assets, including the precautionary motive that has been omitted from much previous literature as intractable. Our model captures many of the principal insights from the existing specialized literature on the precautionary motive,...

The theory of monotone comparative statics and supermodular games is presented as the appropriate tool to model complementarities. The approach, which has not yet been fully incorporated into the standard toolbox of researchers, makes the analysis intuitive and simple, helps in deriving new...

We reconsider the optimal taxation of income from labour and capital in the stochastic growth model analysed by Chari et al. (1994, 1995), but using a linear-quadratic (LQ) approximation to derive a log-linear approximation to the optimal policy rules. The example illustrates how inaccurate...

This Paper examines characterizations of the dynamics for first and second moments of the one-month interest rate, the 12-month excess bond return and exchange rates. The countries considered are the US, Germany, Japan and the UK. Our tests are based on the implications of multi-country versions...
