Here the notes discuss how TFP calculations are actually done in practicality. It also discusses sectoral output functions and uses them to derive aggregated GDP for the economy, introducing the idea of Domar weights on the go. Lastly, it discusses the double deflation vs single deflation method for value-added calculations. This will help us understand the importance of recent changes in the UK value addition GDP accounting change into double deflation.  Click here  to read my notes.

Notes based on the lecture by Prof. Alwyn Young discusses the problems of growth accounting. It describes the growth calculation using the National Accounts, its shortcomings and the potential solution - the chained index. Additionally, the lecture also discusses the growth calculation method adopted by PWT and its potential issues. Click here  to read my notes.

Notes based on the lecture by Prof. Alwyn Young discusses the math described in the paper on PWT construction (Feenstra, Inklaar and Timmer). We also discuss the older and the newer PWT's, their differences and issues. Click here  to read my notes.

In 1905, while only twenty-six years old, Albert Einstein published "On the Electrodynamics of Moving Bodies" and effectively extended classical laws of relativity to all laws of physics, even electrodynamics. In this course, Professor Susskind takes a close look at the special theory of relativity and also at classical field theory. Concepts addressed here includes space-time and four-dimensional space-time, electromagnetic fields and their application to Maxwell's equations. Lecture 1 introduces the idea of how time simultaneity changes across frames. It shows then quantitatively, how space and time coordinates relate to each other, leading to the derivation of Lorentz transformations. This also allows discussion of time and space dilations between frames. Lecture 2 introduces light cones and extends discussions on proper time - the invariant in space-time. The lecture then forwards to discuss 4-vectors and their notations to be utilized ahead. Lecture 3 derives energy

The least action principle is an extremely powerful tool that can be used to determine the trajectories taken up by the particle. It simply states that out of the possible trajectories, the particle will take the one for which the action required is the least. The math involves forming a lagrangian and minimizing the overall lagrangian over the entire trajectory. We can think of it as jittering the trajectory slightly and finding the minimum action path in the neighbourhood. Since lagrangian has units of energy, we can think of it as a fancier version of energy minimisation. Owing to its generalised derivation, it is abundantly used in relativistic physics as well. The concept could be further used to derive a generalised energy conservation principle. Do have a glance at these wonderful concepts!
