TAILIEUCHUNG - How to Build an Economic Model in Your Spare Time

I've seen it claimed that one of the greatest fears that most people have is speaking before a group. I imagine that most assistant professors have this problem, but after many years of giving lectures before several hundred students it goes away. In fact, lecturing can become downright addictive (as my family often reminds me.) As the mathematician R. H. Bing once said: \When I was young, I would rather give a lecture on mathematics than listen to one. Now that I am older and more mature I would rather give two lectures on mathematics than listen to one." Giving lectures is a bit like eating oysters | How to Build an Economic Model in Your Spare Time by Hal R. Varian UC Berkeley December 1994 Current version July 25 2009 Abstract. This is an essay for Passion and Craft Economists at Work edited by Michael Szenberg University of Michigan Press 1997. Keywords. Address. Hal R. Varian Dean School of Information Mangement and Systems UC Berkeley. Web page http hal How to Build an Economic Model in Your Spare Time Hal R. Varian Most of my work in economics involves constructing theoretical models. Over the years I have developed some ways of doing this that may be worth describing to those who aspire to practice this art. In reality the process is much more haphazard than my description would suggest the model of research that I describe is an idealization of reality much like the economic models that I create. But there is probably enough connection with reality to make the description useful which I hope is also true for my economic models. 1. Getting ideas The first step is to get an idea. This is not all that hard to do. The tricky part is to get a good idea. The way you do this is to come up with lots and lots of ideas and throw out all the ones that aren t good. But where to get ideas that s the question. Most graduate students are convinced that the way you get ideas is to read journal articles. But in my experience journals really aren t a very good source of original ideas. You can get lots of things from journal articles technique insight even truth. But most of the time you will only get someone else s ideas. True they may leave a few loose ends lying around that you can pick up on but the reason they are loose is probably that the author thought about them a while and couldn t hgure out what to do with them or decided they were too tedious to bother with which means that it is likely that you will hnd yourself in the same situation. My suggestion is rather different I think that you should look for your ideas outside the academic .
