Previous research

My research focuses on macroeconomics, an area of economics which studies the performance, structure, behavior, and decision-making of an economy as a whole. I use economic models to better understand how the macroeconomic system works, evaluate economic models on the basis of their explanatory power to the reality, and draw implications for better understanding economic policies. My research has two main areas. First, I am merging the insights of the growth theory and the business cycle research, constructing an economic model in which the research and development is incorporated as an integral part of the model economy, and at the same time, the economy is constantly buffeted by random shocks. This research sheds a new light on the cause of what are traditionally considered as short-run economic phenomena from the long-run perspective, and vice versa. I am also studying the information friction in the macroeconomic model. Specifically, I study an environment in which economic agents may not always be fully aware of the current economic conditions, but instead, update their information set only sporadically.


Current research projects

I am working on several projects that bring the aforementioned approach to the actual data using the state-of-the-art estimation technique. In one of them, I investigate the role of the financial market conditions in the Great Recession. I am also studying the optimal monetary policy design in an environment in which the information awareness is a function of economic environments.
