In this paper we estimate production functions for surface and underground coal mines. These production functions are then used to estimate individual mine productivity, to explain productivity differentials across mines, and to assess the importance of several assumed sources of productivity decline in this industry. For readers not familiar with coal-mining operations, we first present a summary discussion of coal-mining technology.
