In a seminal study Hodrick et al. (1991) evaluate the ability of a simple cash-credit model to produce realistic variability in consumption velocity while at the same time successfully explaining other key statistics. Sufficient variability in the latter is found to be associated with far too...

We propose a theory of low-frequency movements in unemployment based on downward real wage rigidities. The theory generates two main predictions: long-run unemployment increases with (i) a fall in long-run productivity growth and (ii) a rise in the variance of productivity growth. Evidence based...

A widely cited failing of real business cycle models is their inability to account for the cyclical patterns of ?nancial variables. Perhaps less well known is the fact that the return to capital and equity are identical in the neoclassical growth model. This paper constructs a measure of the...

Firms in emerging markets are exposed to severe financial frictions and credit constraints, that are exacerbated by the sudden stop of capital inflows. Can monetary policy offset this external credit squeeze? We show that although this may be the case during moderate contractions (or in partial...

This paper analyzes the effects of business cycle volatility on measures of subjective well-being, including self-reported happiness and life satisfaction. I find robust evidence that high inflation and, to a greater extent, unemployment lower perceived well-being. Greater macroeconomic...

Purpose - The purpose of this paper is to examine the effect of economic policy uncertainty (EPU) of China on investment opportunities in five ASEAN economies. Design/methodology/approach - This paper employs advanced empirical approaches, such as Multivariate DCC-GARCH and Continuous Wavelet...

We present a theory of homogeneous volatility bridge estimators for log-price stochastic processes. The main tool of our theory is the parsimonious encoding of the information contained in the open, high and low prices of incomplete bridge, corresponding to given log-price stochastic process,...

In this paper, we present our study on using the GPU to accelerate the computation in pricing financial options. We first introduce the GPU programming and the SABR stochastic volatility model. We then discuss pricing options with quasi-Monte Carlo techniques under the SABR model. In particular,...

This study tests the theory that currency crises are associated with sudden large changes in the structure of foreign exchange market volatility. Due to increases in market uncertainty, crisis periods exhibit abnormally high levels of volatility. By studying short-term changes in volatility...
