We present a consistent neural network based calibration method for a number of volatility models-including the rough volatility family-that performs the calibration task within a few milliseconds for the full implied volatility surface.The aim of neural networks in this work is an off-line...

Purpose This paper discusses the effects of enabling conditions of project knowledge management in building volatile organizational memory. The theoretical rationale underlies a recursive relationship among enabling conditions of project knowledge management, organizational learning and memory....

Common measures of cultural attitudes, such as those constructed from the World Values Survey, are characterized by substantial within-country volatility. This volatility is at odds with the notion of culture adopted in economics: a set of slow-moving traits that determine preferences and...

We lay out an empirical and a theoretical model to analyze the effects of non-fundamental exchange rate volatility on economic activity and welfare. In the first part of the paper, the GARCH-SVARmodel is applied to measure empirically the effect of the conditional exogenous exchange rate...
