We set out a model of a small open economy exporting oil and a traditional exportable in return for produced capital. The small open economy also has local production of a non-traded good. We first observe that the size of the traditional export sector declines with an exogenous increase in the...

We set out dollar-valued net national product for an economy with a wasting essential stock (oil deposit). We take up `maintaining capital intact' and locally unchanging consumption. The percentage change in `net investment' or `genuine savings,' relative to the market rate of interest, denotes...

We set out a model of a two-good, small open economy exporting a traditional exportable in order to …finance capital goods rental payments. We observe that the traditional export sector declines with an exogenous increase in the country's oil export earnings, while the local goods sector...

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...

Poor farmers in developing countries need access to affordable high-quality seed of improved crop varieties to improve their incomes and reduce malnutrition. Vegetables are vital for balanced nutrition, particularly in Africa, where production has been almost static for decades, per capita...

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.
