In this article, the Universal Approximation Theorem of Artificial Neural Networks (ANNs) is applied to the SABR stochastic volatility model in order to construct highly efficient representations. Initially, the SABR approximation of Hagan et al. [2002] is considered, then a more accurate...

We analyze a comprehensive sample of more than 10,000 U.S. OTC stocks. We first show that the OTC market is a large, diverse, and dynamic trading environment with a rich set of regulatory and disclosure regimes, comprising venue rules and state laws beyond SEC regulation. We then exploit this...

In this paper we note that unrelated research in the management and finance fields, if combined, makes predictions concerning board reforms in emerging countries. Specifically, outside directors' demographic characteristics that are salient to foreign investors should reduce stock price...

Studying a comprehensive sample of stocks from the U.S. OTC market, we show that this market is a large and diverse trading environment with a rich set of regulatory and disclosure regimes, comprising venue rules and state laws beyond SEC regulation. We exploit this institutional richness to...

Utilizing VAR-DCC-MVGARCH model and volatility spillover index, we examine international spillovers and spillbacks between SMICs and the U.S. Results show that SMICs and the U.S. present dynamic and asymmetric volatility spillovers and spillbacks during and beyond financial crisis. The effects...

We use weekly data on returns and range-based volatility over 2005-2017 to examine the degree of interconnectedness in financial markets of eleven MENA and four Western economies using the methodology proposed by Diebold and Yilmaz (2009, 2012, 2014). Our findings suggest (a) similar patterns of...

We propose a simple metric to measure two aspects of market integration, namely economic integration (defined as a common cash flow dynamic) and financial integration (defined as a common risk pricing dynamic) and then examine their evolution through time while controlling for volatility. We...

This paper examines the impacts of dividend policy and ownership structure on stock price volatility in the Vietnamese market. The study also tests for the moderating effect of foreign/state ownership on the dividend policy–price volatility relation. The authors use a comprehensive panel...

The purpose of this paper is to investigate the relationship between the share price volatility in Pakistan and their dividend policies which affect the share price. We use dividend yield and dividend payout as proxies of dividend policy, and regress these ratios together with other control...

We analyze the puzzling behavior of the volatility of individual stock returns over the past few decades. The literature has provided many different explanations to the trend in volatility and this paper tests the viability of the different explanations. Virtually all current theoretical...
