A common claim in the nonrenewable resource literature is that improvements in technology may largely offset the effects of increasing scarcity over time. This study provides perhaps the first empirical evidence on this issue by analyzing the determinants of the average finding cost for...

This paper explores the use of low-frequency band-pass filters for describing long-run trends in real mineral commodity prices. This approach has the advantage of allowing long-run trend rates to evolve gradually over time, rather than assuming that they are constant (perhaps with occasional...

This study provides an empirical analysis of the extent to which ongoing technological change has offset the effect of ongoing depletion on the cost of finding additional reserves of natural gas. In the process, we develop a new index of technological change for exploration and development (E&D)...
