Laboratory for Simulation Development User Manual

Lsd is a computer package aiming at facilitating the use of simulation models in Economics. This document is meant to explain the concept of "simulation models" used in Lsd, describe how Lsd manage models, and give instructions for its use. The document is structured in five chapters. The first introduces Lsd and the concept of simulation model. The second chapter is a tutorial for the use of the package. It describes Lsd interfaces for running simulations of existing models and produce modified versions of them. The last three chapters describe three models implemented in Lsd. They are meant to present the functions available in Lsd to write complex models. Readers are not requested to possess a deep knowledge of computer programming, but are supposed to be concerned, if not actually involved, with the issues of using computers for simulation modeling.
