Research Overview

The supply of public goods and the income redistribution are considered to be one of the most important roles of the government. But the discussion on how the government should actualize the optimal supply of public goods and preferable income redistribution will never end. This problem is dependent on the people’s social preferences, and they do not always reveal their true preferences.
My research is to investigate the above issue through theoretical and experimental studies involving questionnaires. People do not always behave selfishly as the economic theory assumes. People sometimes make voluntary contributions to the public benefit and donate to poor people, though they understand they will take a loss. My research intends to reveal the mechanisms behind these behaviors, to clarify the true preferences of people, and to validate a method to implement an optimal supply of public goods and income redistribution.
