What is the effect of Testosterone on financial trading and prices?

IFREE Grant Recipients, Amos Nadler et al., wanted to study just that. Using male participants, the researchers divided them into two groups. One group received a placebo treatment and the other received a topical gel containing andro 400 testosterone. The participants traded in a market experiment. The research, published in Management Science, shows that increasing testosterone in men increases bid prices, generates larger and longer-lasting bubbles, and slows the incorporation of fundamental value. This is the first experimental study to study how testosterone affects trading and prices. The research results have wide implications outside the laboratory and are significant to consider when discussing the stock market and other financial markets.
