In a target-zone exchange rate system, both fundamentals and exchange rate expectations, reflected in interest rate differentials between the domestic and anchor currency, determine the exchange rate. However, the scope to capture exchange rate expectations is limited when policy rates are close...

We present an exchange rate model in which a currency's exchange rate is confined in a wide moving band and a currency crash occurs when the rate breaches the lower boundary. A solution is derived from the standard log exchange rate equation for the model with a smooth-pasting condition at the...

When a currency’s appreciation expectation cannot be offset by lower interest rates which have fallen to the zero lower bound, the monetary authority needs to intervene to prevent currency appreciation due to capital inflows and resulting in foreign reserve accumulation. Based on a standard...

This paper develops a model based on a target-zone approach in which the dynamics of government bond yields follow a quasi-bounded process, such that the zero lower bound (ZLB) can be breached if the probability leakage condition of the dynamics is met. A one-sided U-shaped bond yield...

This paper develops a corporate bond pricing model following the structural approach in which the dynamics of the instantaneous risk-free interest rate are governed by a double square-root (DSR) process. Credit spreads generated from this pricing model depend explicitly upon the levels of...

Our paper presents a crude oil price model in which the price is confined in a wide moving band. A price crash occurs when the price breaches the lower boundary where a smooth-pasting condition is imposed. Using an asymmetric mean-reverting fundamental (supply/demand) shock, the solution derived...

Despite Krugman's (1991) model being a benchmark for modelling target zones, empirical support has been sparse due to the subtle non-linear relationship between the observable exchange rate and underlying unobservable fundamental. This paper provides an alternative approach to derive explicit...

This paper identifies major determinants of mutual fund flows to Hong Kong equities, which is essential for financial regulators and investors to understand potential sources of instability in domestic financial markets. We find that fund flows to global equities outweigh other fund-specific...

This paper assesses whether long-term institutional investors help stabilise or destabilise Hong Kong and international stock markets. We use a novel dataset based on individual funds issued by insurance companies and pension funds worldwide. This allows us to examine each economic region in...

Periodically a major financial innovation creates a new product class that changes the financial landscape. Examples include junk bonds that enabled leveraged buyouts, securitization that stimulated off balance sheet growth in banks, and credit default swaps that offered pure trading in credit...
