AL1: A simple, pure-labour version of the Nelson-Winter growth model, by Andersen [2002-10-29]

This model implements the specification of the pure-labour version of the Nelson-Winter model that was specified by the paper by E. S. Andersen for the DRUID Nelson-Winter Conference, June 2001. The paper is called "Toward a Multiactivity Generalisation of the Nelson-Winter Model". The name of the model is AL Mark 1 (or AL1), where A means knowledge, L means labour, and Mark 1 emphasises that it is just the beginnings of a family of AL models.

nw2004: Extendible Nelson-Winter model emphasising evometric analysis [2004-04-04]

This Nelson-Winter model is largely derived from chapter 12 of their book "Evolutionary Theory of Economic Change". Compered with previous nw versions distributed with Lsd, nw2004 emphasises (a) good design of models and simulation experiments, (b) the explicit treatment of technological regimes, (c) the possibility of switching off monopolistic restraint of investment, (d) the fission of large firms, and (e) statistics for decomposing evolutionary change

nw: The Nelson-Winter model of Schumpeterian competition, by Yildizoglu [2003-03-14]

A Nelson and Winter model derived from the chapter 12 of their book "Evolutionary Theory of Economic Change". The model is an upgrade from a the Nelson and Winter model distributed with previous versions of Lsd. See the model report for details. Upgraded 28 Jan 2003 by Toke Reichstein. Changed to Windows format 14 Mar 2003.

rp2004 - Extendible model of replicator dynamics [2004-04-13]

This file contains the Lsd macro code for exploring models that are based on replicator dynamics. It emphasises structured model development and the use of evolutionary statistics for analysing model behaviour.
