The observed two-part tariff price structure (consisting of a lump-sum price and a linear marginal price) for drinking water in Germany does not reflect the cost structure reported in the literature. Recovering marginal costs from a sample of 251 German counties, we see that there are positive...

The thesis discusses the importance of sustainable urban management, considering the expected increase in urban populations to 70% by 2050. This growth will lead to greater land use and emissions, adversely affecting ecosystems and human health. Sustainable urban management should adopt a...

Economic growth requires growth of energy consumption. In the second half of the twentieth century energy consumption began to outgrow its production and the United States. Consequently, we observe growing dependence of the U.S. economy on energy imports which is causing political and economic...

With a growing population of one hundred twenty-six million (World Bank, 2018), Mexico is accountable for one hundred thirty-one thousand metric tons of CO2 emissions annually, which makes the country 13th largest producer of fossil-fuel CO2 emissions (Boden et al., 2017). Moreover, Mexico's...

The spiral of higher oil prices that is occurring currently is mostly caused not by the lack of reserves, but by increasing demand on the existing supply. However, increase of supply would only temporarily attenuate the issue, as demand is expected to continue to soar and eventually outstrip the...
