We propose to model the joint distribution of bid-ask spreads and log returns of a stock portfolio by using Autoregressive Conditional Double Poisson and GARCH processes for the marginals and vine copulas for the dependence structure. By estimating the joint multivariate distribution of both...

We analyze the effect of bank capital, regulation, and supervision on the annual stock performance of global banks during the period of 1999-2012. We study a large comprehensive panel of international banks and find that higher Tier 1 capital decreases a bank's stock performance over the whole...

We characterize co-movements in investor attention by modeling multivariate internet search volume data. Using a variety of copula models that can capture both asymmetric and skewed dependence, we find empirical evidence of strong non-linear and asymmetric dependence in the attention investors...

Using search volume data on crisis-related queries from Google Trends, we estimate three different measures of market-level and individual crisis sentiment. We find that the stock performance of international banks during the period Q1 2004 to Q4 2012 was significantly driven by investors'...
