Giansante, S., Chiarella, C., Sordi, S. and Vercelli, A., 2012. Structural contagion and vulnerability to unexpected liquidity shortfalls. Journal of Economic Behavior and Organization, 83 (3), 558–569.
This paper assumes that financial fluctuations are the result of the dynamic interaction between liquidity and solvency conditions of individual economic units. The framework is an extention of Sordi and Vercelli (this issue) designed as an heterogeneous agent model which proceeds through discrete time steps within a finite time horizon. The interaction at the micro-level between economic units monitors the spread of contagion and systemic risk, producing interesting complex dynamics. The model is analyzed by means of numerical simulations and systemic risk modelling, where local interaction of units is captured and analysed by the bilateral provision of liquidity among units. The behavior and evolution of economic units are studied for different parameter regimes in order to investigate the relation between units' expectations, liquidity regimes and contagion. Liquidity policy implications are briefly discussed.
