The objective of this paper is to illustrate the connection existing between the asymptotic value of a certain random series and the absence of asset pricing valuation bubbles in stochastic economies with sequential markets. This series, in turn, is closely related to the one proposed by Cass to...

Necessary and sufficient conditions from optimal control theory that are typically used when studying finite and infinite horizon natural resource economics problems are stated. In the finite horizon case their use is demonstrated by deriving an explicit solution of a model describing the...

In an attempt to clean up an unruly literature, we specify the necessary and sufficient conditions for household optimality in a model where money is the only …financial asset and provide the relevant proofs. We use our results to analyse when de‡flationary bubbles can and cannot exist. Our...

In this paper, we make use of the Sobolev space W1,1(R+, Rn) to derive at once the Pontryagin conditions for the standard optimal growth model in continuous time, including a necessary and sufficient transversality condition. An application to the Ramsey model is given. We use an order ideal...

In this paper I analyze the classes of price-paths arising from a non-Ricardian fiscal monetary plan along the lines of the Fiscal Theory of the Price Level (FTPL), under a price invariant nominal money supply rule in a standard Sidrauski-Brock model. I first show that fiscalist speculative...

If average costs in a nonrenewable resource industry are U-shaped, a competitive equilibrium may not be optimal and, indeed, may not exist. Although the differential equation that describes the change in the rate of extraction is the same for planner and firm, the boundary conditions obtained...
