Default risk in equity returns can be measured by structural models of default. In this paper we propose a credit warning signal (CWS) based on the Merton default risk (MDR) model and a Regime-switching default risk (RSDR) model. The RSDR model is a generalization of the MDR model, comprises...

This paper examines the trading behavior of individual investors using a proprietary intraday dataset of a large pool of retail investor aggregate (minute by minute) long and short positions in EUR/USD for the period July 2014 to April 2016. Standard event study analysis shows no significant...

Mortality dynamics are characterized by changes in mortality regimes. This paper describes a Markov regime switching model which incorporates mortality state switches into mortality dynamics. Using the 1901-2005 US population mortality data, we illustrate that regime switching models perform...

We investigate the risk choices of risk averse CEOs. Following recent theoretical work, we expect CEO risk aversion to be more pronounced in firms with high leverage, or high default probability. We find that the CEOs of these firms reduce firm risk, even in the presence of strong risk taking...

The Cypriot banking system has suffered a severe blow last Friday night, after the results of the Eurogroup meeting were announced. Life in the banking system is different since Saturday morning: solutions that were feasible until last Friday (e.g. bank resolutions) might not be feasible this...

We examine which firms are targets of cyberattacks and how they are affected. We find that cyberattacks cause firms to reassess the risks that they are exposed to and their consequences, so that they have real effects on firm policies even when targets are not financially constrained....

We test for the causal impact of analyst coverage on corporate risk-taking in the property and casualty insurance sector, using the exogenous change in analyst coverage introduced by broker closures and mergers. We find that a decrease in analyst coverage promotes an increase in insurers’...
