We introduce external risks, in the form of shocks to the level and volatility of world interest rates, into a small open economy model subject to the risk of sudden stops—large recessions together with abrupt reversals in capital inflows| and characterize optimal macroprudential policy in...

Chinese real business cycle (RBC) exhibits a unique pattern, which is characterized by moderate consumption volatility, substantially low investment volatility, and acyclical trade balance. These features are quite different from business cycles in other emerging markets and cannot be explained...

Standard sticky information pricing models successfully capture the sluggish movement of aggregate prices in response to monetary policy shocks but fail at matching the magnitude and frequency of price changes at the micro level. This paper shows that in a setting where firms choose when to...

We present a model in which temporary shocks can permanently scar the economy's productive capacity. Unemployed workers lose skill and are expensive to retrain, generating multiple steady state unemployment rates. Large temporary shocks push the economy into a liquidity trap, generating...

We present an incomplete markets model to understand the costs and benefits of increasing government debt in a low interest rate environment. Higher risk increases the demand for safe assets, lowering the natural rate of interest below zero, constraining monetary policy at the zero lower bound,...

This paper analyses the implications of the evidence on micro price setting gathered by Price-setting Microdata Analysis Network (PRISMA) for inflation dynamics and monetary policy, relying on calibrated models and direct empirical evidence. According to models calibrated to the euro area micro...

This paper documents five stylised facts relating to price adjustment in the euro area, using various micro price datasets collected in a period with relatively low and stable inflation. First, price changes are infrequent in the core sectors. On average, 12% of consumer prices change each...

This paper uses the factor-augmented VAR (FAVAR) framework to study the impact on the Hong Kong economy of the diverging monetary policies by the Fed, ECB and BoJ as well as the Mainland economy slowdown. The empirical results show that changes in US monetary policy mainly affect interest...

This paper examines Deflationary dynamics in Hong Kong with a linear and a nonlinear neural-network regime-switching (NNRS) model. The NNRS model is superior to the linear model in terms of in-sample specification tests as well as out-of-sample forecasting accuracy. As befitting a small and...

This paper formulates and estimates a three-shock US business cycle model. The estimated model accounts for a substantial fraction of the cyclical variation in output and is consistent with the observed inertia in inflation. This is true even though firms in the model reoptimize prices on...
