Stock Externality vs. Symbiosis in a Forest-Air System

Stock externalities and ecological interaction have similar equilibrium effects. The influence on the dynamics of an ecosystem, however, is quite different. The different effects are laid out theoretically in the context of a forest-air model. We compare a centralized, welfare-maximizing policy and decentralized policies. Finally, we numerically simulate the dynamic differences between stock externalities and ecological interaction.     

Depositors Discipline through Interest Costs during Good and Bad Times: the Role of the Guarantor of Last Resort<Superscript>1</Superscript>

We investigate whether the public sector’s ability as the guarantor of last resort (GLR) to help banks or to guarantee banks’ liabilities affects the sensitivity of interest costs to bank fundamentals. We use a global bank sample and find that the sensitivity is an increasing function of GLR risk, regardless of the method applied to describe this risk. Therefore, our results indicate that increased levels of GLR risk might foster market monitoring by depositors.     

A Review of the Review

In 1997 a process started to review the 1988 Basel I Accord, which ultimately led to the Basel II Accord of June 2004. In this paper Sir Howard Davies, Director of the London School of Economics and Former Chairman of the Financial Services Authority, provides an analysis of this review process. Several issues related to the complexity and implementability of the Accord are discussed. Although the author thinks that Basel II has many appealing aspects (such as the three‐pillar framework), he argues that the outcome is very complicated, it took a very long time, and needs to be adapted in ways not originally envisaged. He calls for a "Review of the Review" to see what lessons can be learnt from the review process which might be helpful for the future.
