This paper investigates whether the effects of weather variability in temperature and precipitation on agricultural output are short- or long-run. In fact, the study addresses two policy-relevant questions: (1) Does temperature or precipitation variability affect agricultural output, and if so,...

It is expected that production in the agricultural sector will be significantly affected by climate change. Therefore, it is projected that countries with extreme climatic conditions will suffer a long-term decline in agricultural productivity beyond the short-term loss of production. Given the...

Given the increasing importance of the mining sector in developing countries, an understanding of their level of environmental efficiency is useful, both to the industry itself and to policymakers. Environmental problems introduced by the sector are attracting extensive attention, so...

This study evaluates the environmental performance of large gold-mining operations by applying a by-production model that specifies emission-generating technology, while incorporating a four-way error approach that captures mine-size heterogeneity, transient and persistent technical efficiency,...

Recent scientific literature shows that in many developing countries, variability in rainfall and temperature in growing season has distortional effects on agricultural output, especially when the variability is high. At what degree or threshold are these variabilities harmful to agricultural...
