  • Dennie van Dolder will be joining as the director of Essex Lab. Dennie says: "Controlled experiments are an invaluable tool to learn more about human judgment and decision making. As director of ESSEXLab, I will dedicate myself to promote and facilitate experimental social science research at the University of Essex. I am excited to join such a vibrant academic community.”

 July 2021

  • ExCESS member Ceren Baysan becomes a member of JPAL.
  • ExCESS members Christoph Siemroth and Simon Weidenholzer have first results for their ESRC grant. Under the grant they use experimental methods both in the lab and in the field to understand how and why people use fintech, such as robo-advice, crowdfunding platforms, and copy-trading. In a first study they discovered that crowdfunding is popular, because it allows investors to choose exactly what project their funds are used for, which is not possible when investing through more conventional channels such as banks or funds.
