The aim of the study is to apply fundamental principles and ethical values in Buddhism to investigate principles in economics. First, I apply the principles of Buddhist Economics to re-examine economic key concepts and principles, such as scarcity, trade-off, choice, utility, consumption, production, price, distribution of income, exchange, market, short/long run, labor, wage, capital, profit etc. And then, I discuss characteristics of ideal economic institutions in accordance with buddhadharma.
