According to “Hotelling rule” price of an “exhaustible resource” exceeds its marginal cost of production in perfect competition equilibrium by amount equal to the opportunity cost of depleting the resource now rather than next periods. This cost is called “scarcity rent”. Oil price exceeds its marginal extraction costs significantly. This can be attributed two different sources: effect of scarc...

There are warning signs for impending scarcity of certain technology metals that play a critical role in high-tech products. The scarce elements are indispensable for the design of modern technologies with superior performance. Material scarcity can restrain future innovations and presents therefore a serious risk that must be counteracted. However, the risk is often underrated in the pursuit o...

Abstract Climate change and global warming are often considered the main reason for water scarcity in Iran. However, there is little evidence showing that arid/wet regions get drier/wetter due to climate change. Some researchers believe parts of challenges Iran arise from bad governance mismanagement resources. To address role on scarcity, this study aims detect drought trends southeast investi...

The Water Poverty Index WPI was created as an interdisciplinary indicator to assess water stress and scarcity, linking physical estimates of water availability with the socioeconomic drivers of poverty. This index has found great relevance in policy making as an effective water management tool, particularly in resources allocation and prioritization processes. Two conceptual weaknesses exist in...
