Bootstrap Tests of Mean-Variance Efficiency with Multiple Portfolio Groupings Staff Working Paper 2014-51 Sermin Gungor, Richard Luger We propose double bootstrap methods to test the mean-variance efficiency hypothesis when multiple portfolio groupings of the test assets are considered jointly rather than individually.

Predicting Financial Stress Events: A Signal Extraction Approach Staff Working Paper 2014-37 Ian Christensen, Fuchun Li The objective of this paper is to propose an early warning system that can predict the likelihood of the occurrence of financial stress events within a given period of time. To achieve this goal, the signal extraction approach proposed by Kaminsky, Lizondo and Reinhart (1998) is used to monitor the evolution of a number of economic indicators that tend to exhibit an unusual behaviour in the periods preceding a financial stress event.

Removal of the Unwinding Provisions in the Automated Clearing Settlement System: A Risk Assessment Staff Discussion Paper 2014-4 Nicholas Labelle, Varya Taylor A default in the Automated Clearing Settlement System (ACSS) occurs when a Direct Clearer is unable to settle its final obligation.

Sheep in Wolf’s Clothing: Using the Least Squares Criterion for Quantile Estimation Staff Working Paper 2014-24 Heng Chen Estimation of the quantile model, especially with a large data set, can be computationally burdensome. This paper proposes using the Gaussian approximation, also known as quantile coupling, to estimate a quantile model.

Monetary Policy Transmission during Financial Crises: An Empirical Analysis Staff Working Paper 2014-21 Tatjana Dahlhaus This paper studies the effects of a monetary policy expansion in the United States during times of high financial stress. The analysis is carried out by introducing a smooth transition factor model where the transition between states (“normal” and high financial stress) depends on a financial conditions index.

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.

The Common Component of CPI: An Alternative Measure of Underlying Inflation for Canada Staff Working Paper 2013-35 Mikael Khan, Louis Morel, Patrick Sabourin In this paper, the authors propose a measure of underlying inflation for Canada obtained from estimating a monthly factor model on individual components of the CPI. This measure, labelled the common component of CPI, has intuitive appeal and a number of interesting features.

Volatility and Liquidity Costs Staff Working Paper 2013-29 Selma Chaker Observed high-frequency prices are contaminated with liquidity costs or market microstructure noise. Using such data, we derive a new asset return variance estimator inspired by the market microstructure literature to explicitly model the noise and remove it from observed returns before estimating their variance.

Multivariate Tests of Mean-Variance Efficiency and Spanning with a Large Number of Assets and Time-Varying Covariances Staff Working Paper 2013-16 Sermin Gungor, Richard Luger We develop a finite-sample procedure to test for mean-variance efficiency and spanning without imposing any parametric assumptions on the distribution of model disturbances.
