This paper estimates the degree of wage and price flexibility of the Hong Kong economy with the use of a stylised dynamic stochastic general equilibrium (DSGE) model developed for the Hong Kong economy. It also studies the factors contributing to deflation in Hong Kong following the Asian...

We present a microfounded two-country model of global imbalances and debt deleveraging. A sustained rise in saving in one country can lead to a worldwide fall in interest rates and an accumulation of debt in the other country. When a subsequent deleveraging shock occurs, interest rates are...

This paper studies a chained credit contract based on Hirakata et al. (2013) in which investors lend funds to banks and banks lend to entrepreneurs in an imperfect financial market. We show that the optimality condition of this contract has a simple, symmetric structure analogous to the one in...

In shaping the evolution of the global financial system in the decade ahead, few events will likely be more significant than capital account liberalisation in China and the internationalisation of the renminbi. This paper provides a theory-based enquiry into the contours of China's international...

The use of international currencies in the global financial system is not symmetric: while a few currencies have been primarily used as investing currencies, a few others have mostly served as funding currencies; only a handful have a better balance functioning as both investing and funding...

This paper uses a New Keynesian framework to study the coordination of fiscal and monetary policies, in response to an inflation shock when the policymaker acts with commitment. We first show that, in the simplest New Keynesian model, fiscal policy plays no part in the optimal policy response,...

This paper studies a simple New-Keynesian model of fiscal and monetary policy coordination when the policymaker acts under commitment. With a New Keynesian Phillips curve it is optimal to control inflation only through the use of monetary policy. But, when price-setters use a Steinsson (2003)...
