We build a new asset pricing framework to study the effects of aggregate illiquidity on asset prices, volatilities and correlations. The Black-Scholes economy is obtained in our framework as the limiting case of perfectly liquid markets. The model is consistent with empirical studies on the...

This paper develops a model which is able to forecast exchange rate turmoil. Our starting point relies on the empirical evidence that exchange rate volatility is not constant. In fact, the modeling strategy adopted refers to the vast literature of the GARCH class of models, where the variance...

We apply network analysis to trace patterns of information transmission in an electronic limit order market. If market orders or large executable limit orders are submitted by informed traders, then resulting star-shaped or diamond-shaped patterns ndash; or trading networks ndash; should be...
