Here are the notes for lecture 2, Here are the slides in 2*2 format. Apologies that there’s no recording. Please try to read Pilbeam, chapters 1-3, for next week. I’ve also posted links to the course pack and some online readings on the course page.
Now, some cool readings:
The scientific evolution of finance
Some advice on writing from mathematician Paul Halmos:
The basic problem in writing mathematics is the same as in writing biology, writing a novel, or writing directions for assembling a harpsichord: the problem is to communicate an idea. To do so, and to do it clearly, you must hâve something to say, and you must hâve someone to say it to, you must organize what you want to say, and you must arrange it in the order you want it said in, you must write it, rewrite it, and re-rewrite it several times, and you must be willing to think hard about and work hard on mechanical details such as diction, notation, and punctuation. That’ s all there is to it.
Riiight.
Abstract. This paper studies the age distribution of firms in Ireland from 1961 to 2009 using data on over 159,000 firms. I build a model which mixes a lognormal distribution of firm size with an exponential distribution of firm age to explain the evolution of these data. The model is fitted using maximum likelihood estimation, and tested using Kolmogorov-Smirnov statistics. The model replicates observed empirical regularities.
Keywords: Firm Age, Firm Size, Firm Growth.
JEL Codes: L20; L25; L26.
