Am I common knowledge for you?
Do you know me? Do I know that you know me? Do you know that I already know that you know me? If you answer “Yes” to the three questions, game theorists would say that I am common knowledge. When I become the common knowledge for you, you could not pretend that you do not know (recognize) me. I challenge you all.
It’s okay, I will let you know about me. My name is Jose Rizal Joesoef, from Malang, Indonesia. I graduated from (1) SMA PPSP IKIP Malang in 1986, (2) Ilmu Ekonomi dan Studi Pembangunan (IESP), Fakultas Ekonomi, Universitas Brawijaya (Unibraw) in 1993, (3) Program Magister Sains (MSc) in Economics, Fakultas Ekonomi, Universitas Gadjah Mada in 1998, and Doctoral Program in Economics, Unibraw in 2010. In short, I have been formally educated by economics.
What is economics all about? Economics teaches us about how to choose alternative(s)–among many alternatives available to us–based on (tangible and intangible) benefit-cost consideration. Leave low-benefit and high-cost alternatives, but pick high-benefit and low-cost ones!
Of course, economics is not the only way of thinking. Besides economics, we have sociology, political sciences, psychology, anthropology, even linguistics (Have you ever heard about Economics of Language?). Economists should not run away from their clients by saying “That is not an economic variable!” Instead, they have to try to analyze human lives in economic way of thinking, or if they could not do so, they should “lower their dignity” by inviting other social scientists to come into economic analysis.
In this blog, you will know more about my thoughts. But, there will be a “risk” after having known me. When I become known to you, you can not pretend that you do not know me and I also can not pretend that I never tell you about me.
