Abstract
We collaborate with several brokerage houses in Dhaka stock market to obtain daily trading data of more than 350 retail stock market traders/investors and conduct a stock market short course training among them. The intervention includes a short course training for the traders. We use lab-in-the-field experiments to examine other behavioural channels such as myopic loss aversion, ambiguity, risk and time preference of these investors. Finally, we combine the knowledge test and experiment results with a unique dataset on daily transactions and portfolio positions of these traders over two years to study the link between individual investment decision under controlled experiment setting and their natural domain.

Experimental Design

Experimental Design
We collaborate with several brokerage houses in Dhaka stock market to obtain daily trading data of more than 350 retail stock market traders/investors and conduct field experiments among them. Our RCTs involve giving financial training to stock market traders and investigating their investment behaviour in a lab-in-the-field setting. We then combine the experiment results with a unique dataset on daily transactions and portfolio positions of these traders over two years to study the link between individual investment decision under controlled experiment setting and their natural domain.

For the financial training component, we randomize participants into two groups: the treatment group receives the training on financial literacy and basic education and the control group will receive the training once the trial ends.

Experimental Design Details
Randomization Method
The participants are individuals from various areas of Dhaka city. They are small investors in the stock market, investing their money through brokerage houses. For this research eight brokerage houses have been selected. Individuals investing through these eight brokerage houses are invited through an open invitation. First 500 individuals showing interest will be supplied with consent forms. Among these 500, we will finally randomly recruit the first 350 individuals supplying their consent forms.

All the randomization in the field and in the lab-in-the-field are done in office by a computer.
