“Itô's Lemma” and the Bellman Equation for Poisson Processes: An Applied View

Using the Hamilton-Jacobi-Bellman equation, we derive both a Keynes-Ramsey rule and a closed form solution for an optimal consumption-investment problem with labor income. The utility function is unbounded and uncertainty stems from a Poisson process. Our results can be derived because of the proofs presented in the accompanying paper by Sennewald (2006). Additional examples are given which highlight the correct use of the Hamilton-Jacobi-Bellman equation and the change-of-variables formula (sometimes referred to as ``Itô's Lemma'') under Poisson uncertainty.     

World Oil Depletion Models: Price effects compared with strategic or technological interventions

World oil depletion, including natural gas liquids, was modelled in the past by many authors. Recently, Guseo and Dalla Valle have introduced and Guidolin has applied a new approach following perturbed life-cycle diffusion models. Here we examine joint effects of economic and strategic or technological interventions using a Generalized Bass Model (GBM). Statistical analysis takes into account three different hierarchical levels: natural diffusion, long memory interventions and stochastic components. The main results confirm the statistical significance of historical 1970s shocks and highlight a strong long memory effect due to an increase in oil production after World War II. The estimated peak-date, 2007, and the 90% depletion time, 2019, are determined under an equilibrium intervention hypothesis.     

Environmental Policy in Open Economies and Monopolistic Competition

This paper analyses the implications of international trade for non-cooperative environmental policy in the case of local production externalities. A particular focus is on the potential effects of regulations on the variety of goods and the resulting international spillover caused by trade. A tougher domestic standard negatively affects the utility of the households abroad, since such a policy reduces their variety of imports (due to fewer domestic product inventions) or their consumption of each imported brand (due to higher import prices). Ignoring the negative spillover, non-cooperative governments implement inefficiently strict standards in equilibrium. In contrast to this clear-cut inefficiency result, the impact of international trade on the state of the environment is ambiguous.
