The financial crisis that surfaced in 2007 has stressed the need to identify the ultimate sources of the incentives that were behind the preceding credit and housing bubbles. To lower the likelihood of future financial collapses, prudent economic policies as well as an adequate regulatory and supervisory framework for financial institutions are required. Monetary policy, in turn, should be dire...

Portfolio credit risk models as well as models for operational risk can often be treated analogously to the collective risk model coming from insurance. Applying the classical Panjer recursion in the collective risk model can lead to numerical instabilities, for instance if the claim number distribution is extended negative binomial or extended logarithmic. We present a generalization of Panjer...

Any absolutely continuous, piecewise smooth, symmetric two-player game can be extended to define a population game in which each player interacts with a large representative subset of the entire population. Assuming that players respond to the payoff gradient over a continuous action space, we obtain nonlinear integro-partial differential equations that are numerically tractable and sometimes a...

The Basel Committee on Banking Supervision (BCBS), in response to the recent financial crisis, has developed new stability rules aimed at preventing financial crises in the future. This paper uses the new Liquidity Ratio (LCR) and attempts to determine the impact of this ratio on the stability of the banking system. The objective of the LCR is to promote the short-term resilience of the liquidi...

This paper studies the interaction between monetary and macro-prudential policies in a simple model with both nominal and financial frictions. The nominal friction gives rise to a conventional monetary policy objective emphasized in the New Keynesian literature. The financial friction, in the form of an occasionally binding collateral constraint, gives rise to a financial stability objective. ...

It is an issue that is both important and timely. Important, because we need to ensure that arrangements for the pursuit of price stability do not inadvertently endanger the stability of the financial system. And we need to ensure that financial system weaknesses do not impede the effective operation of monetary policy. Timely, because the new Basel Capital Accord is focussing additional attent...

This paper studies stability and hybrid synchronization of a time-delay financial hyperchaotic system. Based on Lyapunov stability theorem and differential inequalities, stability is obtained by intermittent linear state feedback control. Furthermore, hybrid synchronization method is firstly proposed to synchronize a financial hyperchaotic system and globally synchronization is obtained by prop...

Analyzing central bank communication during financial crises, we draw on a surprisingly informative parallel between management of natural disasters such as earthquakes on one hand, and the corresponding communication infrastructure and social interaction during financial turmoil, on the other. The role of social and emotional behavior thereof points to the importance of interpersonal comm...
