Some of you have written to me asking what they ask in an ISI interview. Here is my reply:
ISI interview will not be too different from solving problems in an economics entrance exam. Its just that you will now be asked to solve those problems on the board. To prepare for it you need to practice problem solving. Unlike entrance exams, there is lesser or no scope to skip explanations that goes with each step. For example: Suppose you are asked to solve the following problem: Let X and Y be i.i.d Uniform [0, 1]. Find the cumulative distribution function of Z = max{X, Y}. Lets say you know how to do it and you wrote: For 0 < z < 1, Pr(Z ≤ z) = Pr(max{X, Y} ≤ z) = Pr(X ≤ z, Y ≤ z) (why?) = Pr(X ≤ z)Pr(Y ≤ z) (why?) = z^2 Remember to answer those whys along with the derivation. |

Only 7 days left for the ISI Delhi interview.
What should be done now? My focus being solely on ISI D interview. |

ISI entrance doesn't focus on econometrics afaik. The syllabus says probability and statistics upto random variables. Even estimation and hypothesis testing isn't there. I have never come across any senior of mine telling me that he/she was asked an econometrics problem in the interview (Delhi or Kolkata)
Also, please check your email, I have sent you one. |

Hey can someone provide solution to this question?
A professor has 20 hours to allocate between two PhD students. Let x1 and x2 be the time allocated to the two students. The utility of each student is as follows: U1 = −|x1 − 2| and U2 = −|x2 − 8| (a) Find the set of Pareto efficient allocations. (b) What will be the optimal time allocation if the professor maximizes a social function given by : min{U1, U2} |

The answer to this question is that he should allocate 2 hrs to x1 and 8 hrs to x2 because then their utilities will be zero and this is the highest that they can achieve. Because if any other time is alloted to x1, lets say, 4, then his utility will be -2, which is less than zero. Thus, because the utility is negative of modulus, they cannot achieve a higher utility than zero. the no. of hours allocated is to them is kind of bad for the individuals.

Posting my interview experience:
If x is prefered to y then tx is prefered to ty for all t>0. Give an example of such preferences. Suppose an agent has such preferences. We double his income keeping all prices constant. He prefered the bundle (x,y) before. What bundle does he prefer now? |

ISI Kolkata 2018
I was the first one to be interviewed in my slot. As soon as I entered was asked, "Are you based out of Mumbai?" ... I said Yes. Q1. Do you know what is Pareto Optimality? Q2. Was again asked about my definition of Pareto Optimality with few of my own words juggled. Q3. What is the relation between Pareto Optimality and Competitive markets? Q4. What is the intuition behind Pareto Optimality in case of Competitive Markets? Q5. When does Pareto Optimality fails or (market failure) in case of competitive markets? The interviewer gave good reasoning & hints about everything but I was lacking in theoretical understanding of the concepts.
