This paper examines the impact of futures introduction on Bitcoin price crash risk. Using the difference-in-difference (DID) approach, we find that the crash risk of Bitcoin, proxied by negative coefficient of skewness (NCSKEW) and down-to-up volatility (DUVOL) of the five-minute intra-daily...

This research paper is aimed at diagnosing the pricing inefficiencies prevailing in the Indian index options market. The inefficiencies are being revealed by testing the rational expectations hypothesis on the term structure of implied volatilities of index options. In the paper, an effort has...

We propose a new long-memory model with a time-varying fractional integration parameter, evolving non-linearly according to a Logistic Smooth Transition Autoregressive (LSTAR) specification. To estimate the time-varying fractional integration parameter, we implement a method based on the wavelet...

This paper examines the forecast power of subsets of the option-implied interest rate derivatives’ expectations. We use a string market model with three factors to extract the implied risk-neutral volatility of the short-end interest rate term structure. Using data from the Brazil derivatives...

Zur Modellierung des VDAX-Volatilitätsindexes In dieser Arbeit werden zwei verwandte Ansätze zur Modellierung des VDAX-Volatilitätsindexes anhand einer historischen Zeitreihe verglichen. Der Standardansatz ist das weitverbreitete "Mean Reverting Diffusion"-Modell. Die Alternative besteht in...

In continuous time specifications, the prices of interest rate derivative securities depend crucially on the mean reversion parameter of the associated interest rate diffusion equation. This parameter is well known to be subject to estimation bias when standard methods like maximum likelihood...

This paper proposes a nonparametric regression using asymmetric kernel functions for nonnegative, absolutely regular processes, and specializes this technique to estimating scalar diffusion models of spot interest rate. We illustrate the advantages of asymmetric kernel estimators for bias...

The purpose of the paper is twofold. First, it aims at identifying when UK and European (France, Germany, Italy and Spain) Credit Default Swaps(CDSs) exhibit explosivity with respect to their past behaviors. Second, it seeks to quantify the dynamics of CDS volatility spillover effects...

This paper motivates and introduces a two-stage method for estimating diffusion processes based on discretely sampled observations. In the first stage we make use of the feasible central limit theory for realized volatility, as recently developed in Barndorff-Nielsen and Shephard (2002), to...
