Filtration enlargement‐based time series forecast in view of insider trading
Journal of Economic Surveys, Volume 37, Issue 1, Page 112-140, February 2023., 2023 Abstract This survey reviews filtration enlargement models in view of insider trading. Although filtration enlargement aptly models insiders' informational advantage, the theoretical results have not attracted the attention of the empiricists, owing mainly to the lack of a bridge transforming the results to testable hypotheses, and/or the absence of ...
