Current Working Papers

1. Another Look at Great Moderation: The Changes in the Dynamics of Consumption and Output" with Chang-Jin Kim and Chunji Xuan, Revised on March 13, 2015

This paper investigates new implication of Great Moderation in the context of the changes in the dynamics of consumption and output. Since 1984, the volatility of the U.S. real GDP has reduced significantly and has become known as the Great Moderation. However, even though a great deal of literature have addressed the sources of the Great Moderation, no previous study has focused on the relationship between the Great Moderation and the dynamics of macro variables. This paper finds that the reduction in precautionary savings due to lower income uncertainty has both weakened the negative correlation between permanent income and transitory consumption and lowered the persistence of transitory consumption; these have resulted in faster consumption adjustment to long-run level of income. Furthermore, we find that the lower persistence of transitory output due to the improvement in the information technology industry has contributed to the faster adjustment of output to its new long-run level and this result may be related to faster technology diffusion processes. Our results suggest that the Great Moderation has resulted in a change in the dynamics of consumption and output and future research should investigate the role of the change in the dynamics of consumption and output in explaining the source of the Great Moderation.

2. A Flexible Nonlinear Inference with Endogenous Explanatory Variables, Revised on July 3, 2015

Hamilton's (2001) flexible nonlinear inference is not valid in the case of endogenous explanatory variables. This paper proposes a framework for dealing with endogeneity problems in the flexible nonlinear inference. We develop two estimation procedures: a joint estimation procedure and a two-step estimation procedure. The parameters in both models can be estimated by maximum likelihood or numerical Bayesian method. Our approach would be useful in dealing with endogeneity and nonlinearity in the oil-macro relation or in the monetary policy rule.

3. "Public investment in transportation and communication and growth: A dynamic panel approach" with M. Emranul Haque, Revised on May 2009.

This paper investigates the relationship between public investment in transportation and communication and economic growth using traditional instrumental estimation and a mixed fixed and random coefficient approach in the context of a dynamic panel framework. We find that there is a dynamic effect of public investment in transportation and communication on economic growth and its impact seems to be positive and to be a long-run effect. However, for the reverse causal relationship proposed by the investment acceleration hypothesis, we find that there is significant heterogeneity across countries and thus the reverse causality does not seem to run. These results suggest that greater heterogeneity in one causal direction than in the other can be instructive point in terms of more traditional analyses.

4."Nonlinearity in the term structure," Revised on December 2008.

This paper investigates the nature of nonlinearities in the term structure using the flexible approach to nonlinear inference. The paper reports clear evidence of nonlinearity, in contrast to the affine term structure model and consistent with recent claims in the literature. We find that there is a threshold effect of volatility on the interest rate but this effect does not capture the entire nature of the nonlinearity. The quadratic term structure model recently proposed performs better for capturing the nonlinearity than the threshold model but the former model seems to miss some aspect of nonlinearity for short-term rates. However, our flexible nonlinear model which incorporates the threshold effect and the convexity of volatility into the quadratic model, generally performs well for all interest rates. The paper suggests that this model is a promising representation of nonlinearities and out-of-sample forecasts support the claim of nonlinearities.
