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...

This paper obtains monthly implied volatilities of the New York securities market from 1890 to 1934 from interest rate differentials. The implied volatilities did predict the 1929 crash but no other financial crisis. The historical implied volatilities are similar to their modern (2008-2019)...

We investigate all listed firms in Shanghai and Shenzhen stock Exchanges on extreme market movement days over 2010 to 2017, and highlight the important role of price limit on post extreme day stock returns. Utilising daily cash flow data of the largest trading group as a proxy of institutional...

The financial services industry is among the leading industries in IT-spending. Still, little research exists which investigates how IT influences the financial services sector. Against this background, we study how a technology which emerged within the last years affects securities trading:...

We use portfolio theory to quantify the efficiency of state-level sectoral patterns of production in the United States. On the basis of observed growth in sectoral value-added output, we calculate for each state the efficient frontier for investments in the real economy. We study how rapidly...
