Financial Economics Lecture 4

This lecture is all about introducing you to something you won't find anywhere else--the stock market from a physicists viewpoint. Some notes are here, the big set of notes are here. This lecture is based on MFM Osborne's pioneering work in econophysics in the 1970's, his best work is here. Here are the lecture slides.

If you'd like to know more about econophysics, check out the introductory pieces here. This paper is harder, but well worth digging into if you like thinking this way.

Below is a recording of the lecture.

The Age Distribution of Firms in Ireland, 1960-2009

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.
