Morita Lab
Machine-translated · View original
A macroeconomics lab that investigates the channels through which the shocks that drive the business cycle propagate through the economy.

AboutAbout the lab
Uncovering how macroeconomic shocks propagate
The Morita Lab studies macroeconomics and time series analysis.
Using both theory and empirical analysis, the lab clarifies the channels through which the shocks that cause business fluctuations travel through the economy.
Associate Professor Morita has published papers on topics such as the relationship between the effects of fiscal policy and population aging and, as a co-author, the impact of uncertainty about the future on the economy.
Associate Professor Morita has also written a book on macroeconomic analysis using time series methods, and has made the programs used in that analysis publicly available on a website.

*Illustrative imageUncertainty about the Future and the Economy
When the future is unclear, households and firms cut back on spending. The lab builds an indicator of uncertainty during the COVID-19 pandemic from newspaper articles, and analyzes how rising uncertainty affects the economy and how communications from the Bank of Japan are transmitted to the market.
*Illustrative imageHow Effective Is Fiscal Policy?
When the government spends money, how much does the economy as a whole grow? The lab estimates the effect of fiscal spending while taking into account Japan's situation, in which interest rates are stuck near zero, and also examines how much public capital raises output.
