AI won't replace serious economic thinking. But students who know how to use it well will have an edge.
Workshop: 24 May, online, 4 hours.

A utility function that looks simple but has surprisingly rich geometry: u(x,y) = min{x+y, 2x} The indifference curves kink. Three cases, three different types of optimal behaviour, all readable from the picture. Image below. #MSQE#EconSchool#EconTwitter
Here you'll see the graphical proof that there is a possibility that Competitive Equilibrium may not exist in a pure exchange economy. To learn more, visit: https://t.co/3bqQlaSSJn

Here we demonstrate an example where we find all the competitive equilibrium real wages and Pareto efficient allocation in a simple Robinson Crusoe economy where neither the utility function, nor the production function is differentiable.

Here we demonstrate an example where we find all the Pareto efficient allocations in an economy where there are externalities in consumption.

In this example, we observe what happens to Cournot Duopoly equilibrium outcomes when we alter the fixed costs faced by the firms.

We will observe the better-off sets of a consumer with discontinuous preferences here and see whether these sets are open or closed.

Here is an example of a game of effort contributions towards a joint project, where efforts are chosen sequentially by the players in a two-player game. We have used Subgame perfect equilibrium solution concept to predict the outcome of this game.

This isn't a crash course or a tricks-and-shortcuts program.
It's ~100 hours of careful problem-solving, built for ISI MSQE / PhD aspirants.
New cohort starts June 14. https://t.co/tAdSizPv2h
A one-day workshop on Python for Economics, Probability & Statistics.
If you've been meaning to learn Python and never quite had a reason to, this is the reason.

This paragraph by Richard Feynman hits so hard:
“Fall in love with some activity, and do it! Nobody ever figures out what life is all about, and it doesn’t matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough. Work as hard and as much as you want to on the things you like to do the best. Don’t think about what you want to be, but what you want to do. Keep up some kind of a minimum with other things so that society doesn’t stop you from doing anything at all.”
We will be conducting a 10-hour intensive prep program for the MSQE PEB exam on April 25–26, 2026. The sessions will be held live online from 10 AM to 6 PM.

An introductory workshop on LaTeX to be held on 19th April, 2026. This session aims to equip participants with the skills to compose mathematical equations, create professional tables, and generate graphs within the platform. Register here: https://t.co/3ws6Izrusz
Here, we solve the expenditure minimization problems for a consumer who has a bliss point in their consumption set. We examine solutions to the expenditure minimization problem in four different situations for such a consumer.

Here are 100 pages of Econ artwork (including the cover page and excluding the references page). This book is based on the lectures I offer to help prepare students for advanced studies in Economics. It contains hundreds of problems, solved while carefully observing whether the solution lies at the interior, corner, or kinks. The problems presented here, together with the lectures on YouTube (https://t.co/T3jiVlYP7J), can serve as excellent preparation in Microeconomics and Optimization for aspiring Economists. This project is not yet complete, and I will continue to add graphical explanations for solving various Economics problems in the future.

Cover Page:
Here are a couple more examples of solving a firm's cost minimization problem. In the first example, involving plants with convex cost functions, the firm chooses to employ both plants at positive capacities. In the second example, involving plants with concave cost functions, the firm chooses to employ only one of the two plants.
