Staff Analytical Note 2018-41 Bo Young Chang, Jun Yang, Parker Liu
This note examines the costs of the Government of Canada bond buyback and switch programs between 1998 and 2016. Our analysis indicates that the auction design of the buyback program was effective in retiring government debt with minimal costs resulting from bid shading in auctions and price impact.

Staff Working Papers

Equity Option-Implied Probability of Default and Equity Recovery Rate

Staff Working Paper 2016-58 Bo Young Chang, Greg Orosi
There is a close link between prices of equity options and the default probability of a firm. We show that in the presence of positive expected equity recovery, standard methods that assume zero equity recovery at default misestimate the option-implied default probability.

Measuring Uncertainty in Monetary Policy Using Implied Volatility and Realized Volatility

Staff Working Paper 2013-37 Bo Young Chang, Bruno Feunou
We measure uncertainty surrounding the central bank’s future policy rates using implied volatility computed from interest rate option prices and realized volatility computed from intraday prices of interest rate futures.
