Problem 2-Experiments/Randomized Control Trial
Suppose you are interested in studying the effect of academic counselling on the years it takes for a student to obtain an undergraduate degree. You conduct a randomized control trial to answer the question. You randomly assign 2500 individuals in a university in New York to receive academic counselling and 2500 students to not receive any academic counselling.
a. Which people are a part of the treatment group and which people are a part of thecontrol group? b. What regression will you run? Define the variables where required. c. Suppose you estimate = -0.3. Interpret it. d. You test for balance using the variables mentioned in the table below. Based on the results do you think that the treatment and control group are balanced? If your answer is “yes” then explain why. If your answer is “no”, then explain why and mention how will you address the issue of imbalance.
e. Suppose that some unmotivated students in the control group decided to…

Problem 1-Experiments/Randomized Control TrialSuppose you are interested in studying the effect of being a part of the labor union on anindividual’s hourly wage.You collect data on 1000 people and run the following regression.
where is a dummy variable which is equal t to 1 for people who are a part of labor union and0 for others.
a. Suppose you estimate . Interpret b. Do you think is biased or unbiased? Explain.
Now suppose you conduct a randomized control trial to answer the same question. Yourandomly assign some individuals to be a part of the labor union and others to not be a partof the labor union. The first step you take is to ensure that the randomization was donecorrectly. Then you estimate the following equation:
=1 if the student is assigned to be a part of Labor Union=0 if the student is assigned to not be a part of Labor Union
c. Why is it important to ensure that the randomization is done correctly? d. Name any two variables that you can use to test if Treatment and…

- Consider a call option on a stock that does not pay dividends. The stock price is $100 per share, and the risk-free interest rate is 10%. The call strike is $100 (at the money). The stock moves randomly with u=2 and d=0.5. 1. Write the system of equations to replicate the option using A shares and B bonds. 2. Solve the system of equations and determine the number of shares and the number of bonds needed to replicate the option. Show your answer with 4 decimal places (x.xxxx); do not round intermediate calculations. This is easy to do in Excel. A = B = 3. Use A shares and B bonds from the prior question to calculate the premium on the option. Again, do not round intermediate calculations and show your answer with 4 decimal places.
