Market Power and Shadow Prices for Nonrenewable Resources: An Empirical Dynamic Model AgEcon
Lin, C.-Y. Cynthia; Zhang, Wei.
This paper estimates a dynamic model of the world market for nine nonrenewable resources over the period 1970-2004, and tests whether the countries supplying a nonrenewable resource behaved as price-takers or oligopolists. The model generates estimates of the shadow price of the nine minerals with minimal functional form assumptions. The results show that the countries supplying hard coal, lead, and oil behaved as oligopolists during the study period, while the world market for other nonrenewable resources could be characterized as perfectly competitive. The shadow prices do not increase monotonically, which is evidence for stock effects in extraction costs. The shadow prices of most minerals peaked between 1970 and 1980.

Green Technologies for a More Sustainable Agriculture AgEcon
Hrubovcak, James; Vasavada, Utpal; Aldy, Joseph E..
For U.S. agriculture to continue along a sustainable path of economic development, further production increases must be generated by technologies that are both profitable and more environmentally benign. In this context, we assess the role of these green or sustainable technologies in steering agriculture along a more sustainable path. However, the lack of markets for the environmental attributes associated with green technologies can limit their development. In addition, simply making a technology available does not mean it will be adopted. Experience with green technologies such as conservation tillage, integrated pest management, enhanced nutrient management, and precision agriculture demonstrates that even when technologies are profitable, barriers to...

On the existence and optimality of competitive equilibria in nonrenewable resource industries AgEcon
Fisher, Anthony C.; Karp, Larry S..
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 from the transversality conditions for the respective problems (for planner and firm) will not, in general, be the same. If costs are convex, or if there exists a backstop technology which can produce the resource services at sufficiently low cost, the boundary conditions are, however, the same.

How many cake-eaters? Chouette, on a du monde a diner! AgEcon
Favard, Pascal; Karp, Larry S..
We use a cake-eating model with a non-renewable resource and a backstop technology to describe the effect of migration of poor workers into a rich country with surplus labor. Migrants receive a large transfer from natives. If future migration is anticipated, natives' flow of utility increases discontinuously at the time of migration. Migration at time 0 may cause the initial flow of natives~ utility to be higher. However, the present discounted value of the stream of per capita utility falls. Thus, when migration occurs, it may benefit the current generation of natives, although it harms other generations.
