Dr. Yuzo Kumasaka has extensive experience with econometrics.　
He has been constructing econometric models and forecasting the economy since 1973. Dr. Kumasaka has constructed CQMs for the United States, Japan (for Global Security Research Institute at Keio University), Thailand (for National Economic and Social Development Authority), Philippines (for National Economic Development Authority) and Malaysia (for Bank Negara Malaysia). Most noteworthy, since the early 1990s he has forecasted the U.S. economy every week using CQM and has published the weekly U.S. economic outlook report for the current and next quarters based on the CQM forecast (Utilization and Precision of The U.S. CQM.pdf)"ITeconomy."
As a chief director of the project "Accelerating Japan's Economic Growth" commissioned by the Liberal Democratic Party (LDP) Think Tank (Members for Risng Tide Policy.pdf), Dr. Kumasaka proposed a "Rising Tide Policy" to the first Abe Cabinet. By showing empirically that Japan's potential growth is much higher than 3% because of the utilization of IT, the project advised that Japan could achieve a 3%-4% economic growth rate. He also directed the project "The Effect of the IT on the Japanese Industries" for Nihon Keidanren (Japanese Business Federation).
Dr. Kumasaka worked as a project leader for Potential Output for East Asian Countries for 2010-11 at the Economic Research Institute for ASEAN and East Asia.
