Asymmetric behaviour has been documented in unemployment rates which increase quickly in recessions but decline relatively slowly during expansions. To model such asymmetric dynamics, this paper provides a rigorous derivation of the asymmetric mean-reverting fundamental dynamics governing the...

The Hong Kong Monetary Authority has completed a research study on the setting of mortgage rate by Authorized Institutions (AIs). The purpose of the project is to consider whether in an environment of intensive competition and, until recently, abundant liquidity in the banking system, the AIs...
