WWW Experiments for Economists, a Technical Introduction

In this document we sketch some techniques that are useful when developing www moderated experiments. We describe a modular and, hence, very flexible approach. On all levels (clients, server, programming language, database, etc.) we compare alternatives that can be integrated. We argue that a very wide range of experiments can be covered. There is no restriction to particular hardware, clients, operating systems, programming languages, etc. Laboratories from all over the world can be linked together with the help of the internet.
