The effects of resource depletion on coal mining productivity

Abstract

D De ep pa ar rt ta am me en nt to o d de e E Ec co on no om mí ía a U Un ni iv ve er rs si id da ad d d de e O Ov vi ie ed do oAbstract: Production risk has generally not been taken into account when measuring productivity growth and traditional productivity indices thus provide an incomplete picture of producer performance and welfare when risk matters. Using standard concepts from the literature on uncertainty we introduce a measure of total factor productivity growth, defined in physical terms, which takes risk considerations into account. This measure is decomposed in order to identify the relative importance of the factors contributing to risk. The measure is illustrated using data from Spanish dairy farms.

Global coal production outlooks based on a logistic model

“…In addition, better extraction technologies have been found to be largely obscured by decreasing reserve levels as the coal becomes increasingly complicated to mine, effectively meaning that depletion has been able to offset many of the gains from new technology [18,19]. This is in line with the explanations provided by Bardi and Lavacchi [14].…”

Energy Return on Investment for Norwegian Oil and Gas from 1991 to 2008

“…The question of which is "winning" cannot be answered theoretically, but must be addressed empirically [26,27]. We do this by assessing the time trends in the efficiency (i.e., EROI) with which we produce oil and gas.…”

Evaluating and modeling ecosystem service loss of coal mining: A case study of Mentougou district of Beijing, China

“…Sulfur in coal dust affected the respiration of the crops. If it reacts with dew and rainwater, it will produce the acidic compound which wound burn the crop lamina and reduce the photosynthesis activity and crop outputs (Rodríguez and Arias, 2008). …”
