Characterizing the Sustainability Problem in an Exhaustible Resource Model

Mitra, Tapan; Asheim, Geir B.; Buchholz, Wolfgang; … - 2021

The Dasgupta-Heal-Solow-Stiglitz model of capital accumulation and resource depletion poses the following sustainability problem: is it feasible to sustain indefinitely a level of consumption that is bounded away from zero? We provide a complete technological characterization of the...

Regime Shifts and Uncertainty in Pollution Control

Zeeuw, Aart de; Zemel, Amos - 2021

We develop a simple model of managing a system subject to pollution damage under risk of an abrupt and random jump in the damage coefficient. The model allows the full dynamic characterization of the optimal emission policies under uncertainty. The results, that imply prudent behavior due to...

Value Function Iteration as a Solution Method for the Ramsey Model

Heer, Burkhard; Maußner, Alfred - 2021

Value function iteration is one of the standard tools for the solution of the Ramsey model. We compare six different ways of value function iteration with regard to speed and precision. We find that value function iteration with cubic spline interpolation between grid points dominates the other...

Private Provision of Public Goods and Information Diffusion in Social Groups

Scharf, Kimberley A. - 2021

We describe a dynamic model of costly information sharing, where private information affecting collective-value actions is transmitted by social proximity. Individuals make voluntary contributions towards the provision of a pure public good, and information transmission about quality of...

Forecasting Exchange Rates : An Investor Perspective

Melvin, Michael - 2013

The popular scholarly exercise of evaluating exchange rate forecasting models relative to a random walk was stimulated by the well-cited Meese and Rogoff (1983) paper. Practitioners who construct quantitative models for trading exchange rates approach forecasting from a different perspective....
