We examine the relationship between broker network connectivity and stock returns in an order-driven market.

We derive the theoretical hitting probability distribution for the long-until-barrier strategies and the conditions for statistical arbitrage. We...

We propose an extended SVAR model to investigate the responses of the macroeconomic volatility to financial uncertainty shocks. The empirical model features the time-varying stochastic volatility-in-mean process where parameters allow for (i) the bilateral simultaneity between the shocks hitting...
