Testing for the Diffusion Matrix in a Continuous-Time Markov Process Model with Applications to the Term Structure of Interest Rates Staff Working Paper 2015-17 Fuchun Li The author proposes a test for the parametric specification of each component in the diffusion matrix of a d-dimensional diffusion process. Overall, d (d-1)/2 test statistics are constructed for the off-diagonal components, while d test statistics are constructed for the main diagonal components.

Persistent Leverage in Portfolio Sorts: An Artifact of Measurement Error? Staff Working Paper 2014-55 Michael Mueller Studies such as Lemmon, Roberts and Zender (2008) demonstrate how stable firms’ capital structures are over time, and raise the question of whether new theories of capital structure are needed to explain these phenomena.

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.
