Revisiting Fisher Equation in BRICS Countries

Understanding the Fisher Equation∗

It is argued that univariate long memory estimates based on ex post data tend to underestimate the persistence of ex ante variables (and, hence, that of the ex post variables themselves) because of the presence of unanticipated shocks whose short run volatility masks the degree of long range dependence in the data. Empirical estimates of long range dependence in the Fisher equation are shown to...

Revisiting Fisher Kernels for Document Similarities

This paper presents a new metric to compute similarities between textual documents, based on the Fisher information kernel as proposed by T. Hofmann. By considering a new point-of-view on the embedding vector space and proposing a more appropriate way of handling the Fisher information matrix, we derive a new form of the kernel that yields significant improvements on an information retrieval ta...

Stock Return Volatility Effect: Study of BRICS Countries

The present study examines the stock return volatility relationship of emerging economies from 2007 to 2013 which also includes the financial crisis of 2008 and its impact on emerging economies of the world. For the methodology, GARCH model is used to examine the impact of news coming from US which is affecting the returns of global index S&P 500 as well as the returns generated by the indices ...
