In this study, we document a strong positive relation between pre-crisis managerial ability and corporate investment during the crisis period, which remains robust in the presence of a large array of control variables capturing corporate governance attributes, executive compensation incentives and CEO characteristics.
Banks that follow conditional conservatism in their loan loss accounting treatments benefit from a reduction in crash risk. The key discretionary loan loss accounting channels are provisions and allowances.
56 Pages · Posted: 6 Mar 2017 · Last revised: 4 Aug 2019 | We estimate the term structures of risk-neutral forward variance and skewness, and examine their predictive power for equity market excess returns and variance. We use Partial Least Squares to extract a single predictive factor from each term structure that is motivated by the theoretical implications of affine no-arbitrage models.
When a sole individual acts as both CEO and chair of the board of a firm, the resulting CEO duality creates one of the most contentious issues in the field of strategic leadership (Dalton et al., 2007; Finkelstein et al., 2009).
38 Pages · Posted: 7 Nov 2016 · Last revised: 28 Nov 2017 | This study examines the impact of CEO duality on firms’ internal capital allocation efficiency. We observe that when the CEO is also chair of the board, diversified firms make inefficient investments, as they allocate more capital to business segments with relatively low growth opportunities over segments with high growth opportunities.

13 Pages · Posted: May 2006 · Citations: 17 | The option pricing ability of Robust Artificial Neural Networks optimised with the Huber function is compared against those optimised with Least Squares. Comparison is in respect to pricing European call options on the S&P 500 using daily data for the period April 1998 to August 2001.
We combine parametric models and feedforward artificial neural networks to price and trade European S&P500 Index options. Artificial neural networks are optimised on a hybrid target function consisted by the standardised residual term between the actual market price and the option estimate of a certain parametric model.
In this paper we compare the predictive ability of the Black-Scholes Formula (BSF) and Artificial Neural Networks (ANNs) to price call options by exploiting historical volatility measures.
