福岡会場 大学院説明会（留学生対象）

2008年にサトシ・ナカモト氏によって提案されたブロックチェーン技術は，当初の暗号通貨への利用の範囲を超えて，デジタル変革時代の新しい信用構築基盤としての広範な分野への活用が期待されています。本ミニ講演では，ブロックチェーン技術の基本とその活用事例を紹介します。

Vast majority of people seem to uncritically accept a positive money interest and have never seriously tried to investigate the issue of the origin of money interest. Both the standard economists and heterodox economists tacitly accept time preference theory in which positive interest derives from consumption behavior at different time periods. That is to say, time preference theory implicitly assumes that people prefer immediate consumption to later consumption. Such theoretical framework of time preference theory also created discounting practice with positive interest rate. A well-known economist, J. M. Keynes is no exception on this matter. In fact, Keynes accepted time preference theory without serious consideration and presented a theory based on the similar assumption in Chapter 17 of his The General Theory of Employment, Interest, and Money, published in 1936.
This short lecture presents an alternative theory of the origin of money interest in relation to the second law of thermodynamics and discusses a serous defect of the present value maximization criterion when applied to exhaustible resource allocation problem using discounting practice over time.
