gravity recovery and climate experiment (grace) satellite gravimetry mission launched in march 2002 based on its twin gravimetric satellites makes application of both high-low (hl) and law-low (ll) gravimetric techniques possible. the ll is based on satellite-to-satellite tracking (sst) via the one way two frequencies k-band-ranging between the two grace satellites. as a result of combination o...

We handle two major issues in applying extreme value analysis to financial time series, bias and serial dependence, jointly. This is achieved by studying bias correction method when observations exhibit weakly serial dependence, namely the β−mixing series. For estimating the extreme value index, we propose an asymptotically unbiased estimator and prove its asymptotic normality under the β−mixin...

In developing countries, weak institutional quality can increase the probability of applying discretionary policies and can have a great impact on their double-digit inflation. Surico (2008) calculated inflation bias, but he considered just monetary policy and he did not pay attention to the institutions. Therefore, we design a model which considers the discretion in monetary and fiscal policie...
