A Fuzzy Framework for Realized Volatility Prediction: Empirical Evidence From Equity Markets
Journal of Forecasting, EarlyView.ABSTRACT This study introduces a realized volatility fuzzy time series (RV‐FTS) model that applies a fuzzy c‐means clustering algorithm to estimate time‐varying c$$ c $$ latent volatility states and their corresponding membership degrees. These memberships are used to construct a fuzzified volatility estimate as a weighted average of cluster centroids.

The Case of Fleeting Orders and Flickering Quotes
Journal of Futures Markets, EarlyView.ABSTRACT The literature controversially discusses the ambiguous motives and driving forces behind quickly cancelled limit orders (fleeting orders), which are characteristic of high‐frequency markets. In particular, manipulative and dysfunctional characteristics are feared. We analyze top‐of‐book fleeting orders—so‐called flickering quotes—and show with

Rural–Urban Digital Divide: Evidence From Indian States
International Journal of Finance &Economics, EarlyView.ABSTRACT The Indian economy has achieved significant progress in recent years, with the country expected to contribute about 16% of the global growth. However, at the sub‐national level, economic development has been quite disparate over the decades, with widening inequality between the richer western and southern states and other parts of the country.
