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 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 examines the dynamic interactions between the government bond yields of Germany, Japan and the US and their exchange rate expectations anticipated in the currency options, i.e., risk reversals (put premia) of the US dollar versus the yen and euro. Short-term, one-way information flow...

A sign of emerging downward trends in the carbon intensity of energy (CO2 intensity) is an early indicator of progress in transitioning to low-emission energy. To trade off the obligation of reducing carbon emissions against the cost saving benefits of using fossil fuels, a country may choose an...

Using a non-Gaussian affine term-structure model, this paper evaluates the effectiveness of the date-based forward guidance at the zero lower bound. The model extracts the expected dynamics of two state variables (the short-term interest rate and its mean) embedded in the entire Treasury yield...

The large presence of global banks in Hong Kong offers a well suited empirical setting to study the capital management of foreign bank subsidiaries from a host country perspective. Specifically, this paper uses the trade-off theory of leverage to investigate whether the leverage dynamics of...
