SUMMARY:Physics Colloquium
DESCRIPTION:Abstract: In 1955\, Amal Raychaudhuri analysed the properties of space-time and derived an equation for a geometric quantity known as "expansion". This tells us how the volume of a small unit of space expands or contracts along a geodesic curve. His equation was to have far-reaching consequences. It was adapted by Hawking to prove his famous singularity theorems and a variant of the equation was used by Penrose to prove the inevitability of black hole formation. Subsequently the equation has helped to understand entropy and the laws of thermodynamics\, as generalised to include gravitating systems. It has also been used to illuminate the remarkable connection between gravity and quantum entanglement.  These developments will be surveyed in a broad\, non-technical framework. \nAbout the Speaker: Prof. Sunil Mukhi is Raja Ramanna Chair and Emeritus Professor at IISER Pune and an Adjunct faculty at TIFR-ICTS Bengaluru. He obtained a Ph.D. in Theoretical Physics from Stony Brook University in 1981. His field of specialisation is theoretical particle physics. His research has explored mathematical aspects of Supersymmetry\, Conformal Field Theory\, String Theory and Quantum Gravity. After working at the Tata Institute of Fundamental Research\, Mumbai for 27 years\, he moved to the Indian Institute of Science Education and Research\, Pune in 2012 as Chair of the Physics Department. He has taken sabbaticals at CERN\, Geneva\, the Institute for Advanced Study\, Princeton and Trinity College\, Cambridge.\nHe is a Fellow of the Indian Academy of Sciences\, the Indian National Science Academy and The World Academy of Sciences\, and received the Shanti Swarup Bhatnagar Prize in Physical Sciences in 1999. He has been an Editor of the Journal of High Energy Physics\, the leading journal in the field\, since its inception in 1997. He was recently elected to the Board of Trustees of the Association of Members of the Institute for Advanced Study\, Princeton. \nWe look forward to your active participation.

SUMMARY:Economics Department | Weekly Seminars
DESCRIPTION:Dear All\, \nThe Department of Economics invites you to their weekly seminar on Wednesday\, March 19th\, 2025. \nTime: 1:40 PM to 2:50 PM \n Venue: AC 04 301 \n Speaker: Prof. Christopher Carroll \n Title: Welfare and Spending Effects of Consumption Stimulus Policies. \nAbstract:  Using a heterogeneous agent model calibrated to match measured spending dynamics over four years following an income shock (Fagereng\, Holm\, and Natvik (2021))\, we assess the effectiveness of three fiscal stimulus policies employed during recent recessions. Unemployment insurance (UI) extensions are the clear “bang for the buck” winner when effectiveness is measured in utility terms. Stimulus checks are second best and have two advantages (over UI): they arrive faster\, and they are scalable to any desired size. A temporary (two-year) cut in the rate of wage taxation is considerably less effective than the other policies and has negligible effects in the version of our model without a multiplier. \n

SUMMARY:PhD Defense Seminar | Mahima Mukhija | 19th March 2025
DESCRIPTION:Dear All\, \nThe Department of Economics invites you to their PhD Defense Seminar on Wednesday\, March 19th\, 2025. \nTime: 3:00 PM to 4:00 PM \n Venue: AC 04 309 \n Speaker:  Mahima Mukhija \n Title: Procrastination and Task Quality: Role of Information regarding Time Needed \nAbstract: Procrastination is generally conceptualized as the unnecessary delay of an intended task. It can lead to significant economic losses. There is a huge and growing body of literature on procrastination\, and a major segment focuses on its causes. The same can be broadly divided into two categories: internal factors and external factors. There has been ample research in the former category\, while there is a shortage in the latter. This work contributes to the scant literature in the latter category by exploring the role of a task-related factor\, information regarding the time needed to complete a task\, in explaining procrastination. Studies have suggested that errors in estimating the time needed to complete a task may be attributed to procrastination. In my thesis\, I investigate the reverse channel\, i.e.\, whether procrastination can be attributed to the underestimation of time needed to complete the task\, via a theoretical model and two experimental studies. \nThe first chapter introduces a basic single agent choice model where he has to perform an intended task to the best of quality before the deadline ends. The case with information regarding the time needed is compared to the one without information\, both with and without present bias. The model predicts a reduction in procrastination after providing information regarding the time needed for a task only if the gap between the actual time needed and the time till the deadline is not low enough for the agent to catch up by learning. \nThe second chapter pertains to a laboratory experiment conducted to test the predictions derived from the theoretical model in chapter one. The subjects were required to complete a typing task over some time\, and their actual time allocation for the task was observed. The data supports the predictions made in chapter one. There is evidence of endogenous learning in the absence of full information regarding the time needed to complete the task. Also\, there exists a strong negative relationship between delay and task performance. \nIn the third chapter\, the question is studied in a natural environment via a quasi-natural experiment conducted with undergraduate students in a classroom setting. Information about the time needed to complete a quiz during the course varied by quizzes. The results showed a strong negative relationship between delay and performance. Also\, the data provided weak evidence of the provision of information regarding the time needed to complete the quiz\, leading to reduced procrastination (task delay) and improved performance.
