Strategic considerations of exploration and extraction are investigated in a two-player, two-period, two-stage perfect equilibrium framework. Relative to two "plant" monopoly, the duopolists explore more and extract more period by period. A mixed game in which there is cooperation "upstream" in...

We consider a competitive extraction industry comprising many small firms, each with a slightly different quality of mineral holdings. With "rapidly" declining quality of holding per firm, we observe rent declining over an interval. We then take up the familiar planning model and isolate the tax...

Each extractor has a distinct quadratic extraction cost and faces a linear industry demand schedule. We observe that the open loop and closed loop solutions are the same if initial stocks are such that each competitor is extracting in every period in which her competitors are extracting.

A group of firms issuing equity claims on its capital stock have all capital as an exhaustible resource. We introduce such firms into the set of n firms who have issued equities in the Capital Asset Pricing Model (CAPM) and observe how the interaction of demand for oil by users and demand for...

We set out a small, open economy model of a city, one with local housing, government production and a non-traded good. We observe that a positive shift in labor productivity in the export sector generally results in a larger, higher-wage and more densely settled city. Production of the local...

We introduce decay in produced capital and exogenous technical progress to the recent "Solow Model" of Asheim et al. with population growth and observe the possible collapse of the economy given too high a rate of decay. "Enough" technical progress can restore sustainable per capita consumption.
