Taka, YAMADA, Ph.D.: vitae
Welcome to my homepage! My academic professional interests lie in unraveling the effects and mechanisms of various problems associated with economic development and providing possible prescriptions for these problems.
As of 2025, I have around 15 years of practical professional experience in the economic development arena across Asia and the Pacific, South Asia, Central America, and the Caribbean. In practice, I have engaged in economic analysis and policy dialogue with client authorities in Laos, Myanmar, Vietnam, Cambodia, El Salvador, and Honduras. I received a doctoral degree from Nagoya University, Japan, and the post-graduate diploma from Pennsylvania State University.
