We present a state-dependent pricing model that generates inflation fluctuations from idiosyncratic shocks to the cost of price changes of individual firms. A firm's nominal price increase, lowers other firms' relative prices, thereby inducing further nominal price increases. This snow-ball...

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....

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...
