• A Distributional Approach to Realized Volatility

  Staff Working Paper 2013-49 Selma Chaker, Nour Meddahi

  This paper proposes new measures of the integrated variance, measures which use high-frequency bid-ask spreads and quoted depths. The traditional approach assumes that the mid-quote is a good measure of frictionless price.

• Volatility Forecasting when the Noise Variance Is Time-Varying

  Staff Working Paper 2013-48 Selma Chaker, Nour Meddahi

  This paper explores the volatility forecasting implications of a model in which the friction in high-frequency prices is related to the true underlying volatility. The contribution of this paper is to propose a framework under which the realized variance may improve volatility forecasting if the noise variance is related to the true return volatility.
