Intraday liquidity management: a tale of games banks play
Over the last few decades, most central banks, concerned about settlement risks inherent in payment netting systems, have implemented real-time gross settlement (RTGS) systems. Although RTGS systems can significantly reduce settlement risk, they require greater liquidity to smooth nonsynchronized payment flows. Thus, central banks typically provide intraday credit to member banks, either as collateralized credit or priced credit. Because intraday credit is costly for banks, how intraday liquidity is managed has become a competitive parameter in commercial banking and a policy concern of ...

Conflict, evolution, hegemony, and the power of the state
In a model of evolution driven by conflict between societies more powerful states have an advantage. When the influence of outsiders is small we show that this results in a tendency to hegemony. In a simple example in which institutions differ in their ?exclusiveness? we find that these hegemonies will be inefficiently ?extractive? in the sense of having inefficiently high taxes, high compensation for state officials, and low welfare.

Illiquidity in the interbank payment system following wide-scale disruptions
We show how the interbank payment system can become illiquid following wide-scale disruptions. Two forces are at play in such disruptions-operational problems and changes in participants' behavior. We model the interbank payment system as an n-player game and utilize the concept of a potential function to describe the process by which one of multiple equilibria emerges after a wide-scale disruption. If the disruption is large enough, hits a key geographic area, or hits a "too-big-to-fail" participant, then the coordination of payment processing can break down, and central bank intervention ...

Financial matchmakers in credit markets with heterogeneous borrowers
What happens when liquidity increases in credit markets and more funds are channeled from borrowers to lenders? We examine this question in a general equilibrium model where financial matchmakers help borrowers (firms) and lenders (households) search out and negotiate profitable matches and where the composition of heterogeneous borrowers adjusts to satisfy equilibrium entry conditions. We find that enhanced liquidity causes entry by all borrowers and tends to benefit low-quality borrowers disproportionately. However, liquid credit markets may or may not be associated with higher output and ...
