Effectiveness of State Reserve Requirements
In recent years many banks have withdrawn from the FRS, and the primary reason given is that they must hold a larger share of their assets in non-earning form as members than if they were nonmembers.1 The FRS has proposed to reduce member bank reserve requirements as a means of making membership more attractive. State bank regulators, however, might wish to counter this action in order to keep ...
متن کاملEnergy and Reserve Market Clearing to Consider Interruptible Loads
This paper demonstrates a method to how reserve capacity and cost allocation could be determined in a pool-based and disaggregated market model. The method considers both the spinning reserve and interruptible loads as the operating reserve services. In the proposed market, generators and consumers (including participation of interruptible loads) submit offers and bids to the independent system...
متن کاملMatching marine reserve design to reserve objectives.
Recent interest in using marine reserves for marine resource management and conservation has largely been driven by the hope that reserves might counteract declines in fish populations and protect the biodiversity of the seas. However, the creation of reserves has led to dissension from some interested groups, such as fishermen, who fear that reserves will do more harm than good. These perceive...
متن کاملA Growth Perspective of Foreign Reserve Accumulation
Based on a dynamic open-economy macroeconomic model, this paper aims at understanding the contribution of domestic financial under-development to foreign reserve accumulation in some emerging market economies, especially in China. It is argued that foreign reserve accumulation is a consequence of a growth strategy induced by strong capital investment in a financially constrained economy. It is ...
متن کاملCatastrophe Management and Inter-Reserve Distance for Marine Reserve Networks
We consider the optimal spacing between marine reserves for maximising the viability of a species occupying a reserve network. The closer the networks are placed together, the higher the probability of colonisation of an empty reserve by an occupied reserve, thus increasing population viability. However, the closer the networks are placed together, the higher the probability that a catastrophe ...
