Alternatives to Dark Matter hypothesis

Evolution of the Universe

Baryonic Acoustic Oscillations

Image
Soon after the big bang, followed by inflationary epoch, the universe was in a hot plasmonic state containing a mixture of radiation and baryons. The universe being in this fluid state made it possible for the pressure waves to travel. So, the universe had baryons and environment to support acoustic oscillations.

Policy Space and Modern Trade Agreements

In the paper, the author's then went ahead to examine the extent to which various regimes constraint policy space for member nations. They studied four US agreements

COVID testing effects positivity rates

Image
In the circle of family and friends, there has been a lot of discussion about India's poor COVID management. Although I do not disagree with them, the situation could have been managed in a better fashion given the late onset of COVID relative to the rest of the world.

Analyzing COVID pharmacology

Image
The novel corona-virus continues to puzzle researchers around the world, thereby raising risks to magnanimous scales. However, the good news is that the human efforts are matching its levels as well. One such research was performed by Dr. Daniel Jacobson’s group who utilized worlds second fastest supercomputer at Oak Ridge National Lab in Tennesse and studied around 2.5 billion genetic combinations.

Dynamics of External Adjustment

Dollar currency paradigm means that dollar matters a lot in global trade. So suppose, India and Brazil are involved in a bilateral trade whereby India buys oil from Brazil while Brazil buys pharmaceutical drugs from India.

Evolution of Top and Bottom CO2 emitters 1961-2010

Generally, some of the developed countries (mainly the US) claim that it is the developing world responsible for the current state of emissions and they should be the one held responsible and not the developed countries.

Inflation Expectations went right!

Interestingly in my MSc. essay, I had observed that the direct impact of oil prices are negative on CPI but positive on WPI.

I have been asked several times if my chemical engineering study was useful at all in economies. As I always used to answer, the concepts are omnipresent.

How dynamic are fuel prices?

Image
Petrol prices were market-linked in 2010 and diesel later in 2014 for retail consumers. Although I do encourage and support this move as they would improve fiscal balance, make energy usage more sufficient and would be better for the environment as well.

Macroeconomics of Flu

The macroeconomic flu is a temporary negative supply and demand shock, that is a temporary decline in output followed by a quick recovery.

Is Trade War with China a good idea for India?

Image

Where do we find Entanglement in Nature

(I) Still existing as one of the biggest mysteries is that of quantum entanglement . Even the greatest minds of the century, like Albert Einstein also had to struggle to understand such a phenomenon and was compelled to say it as “spooky phenomenon at some distance”.

There's no clear demarcation between ML, AI, statistics and econometrics. But there are some techniques under ML/AI that are not present in econometrics and could be quite beneficial to adopt.

Nash eqm vs Subgame perfect eqm

This post is especially for the new-comers to the game theory. When I had started studying these topics, I remember being struggling to properly understand the differences and get an intuition of what's happening and I had seen my friends struggle as well.

Life and Lagrangian - Decision making and Economics

Image
In this post, I review an interesting interview about the decision-making process by an ex-spy and the National Security Advisor of India and connect it with a simplistic optimization procedure used in fundamentally and frequently in  economics .

Particle Scale Liquid Spreading in Trickle Bed Reactors

I performed simulations in HPC-computing facility of IITD, the 4th fastest supercomputer in India.  With emission norms getting more and more stringent, it has become important to improve the performance of trickle bed reactors to produce better fuel quality with sulphur content less than 10 ppm (e.g. ultra-low sulphur diesel).

Impact of Aadhar on Welfare in Welfare Programmes

Aadhaar, India's ambitious biometric ID project, was portrayed as one that would enhance India's welfare efforts by promoting inclusion and reducing corruption. From being a voluntary ID, it has become de facto compulsory for most welfare programmes such as the National Rural Employment Guarantee Act (NREGA) and the Public Distribution System (PDS).

Modern Business Cycle Model with Search Friction

The big picture in this model is that markets do not clear instantaneously to make everyone happy. There are frictions in the labour market. This Diamond, Pissarides model has real unemployment. In RBC models we witness that unemployment is voluntary in nature.

Monetization of Govt Debt

Image
There is a lot of concern in some quarters about central banks printing money to finance large budget deficits. And in other quarters there is concern that central banks are doing too little of it. Some worry that central banks are lending directly to the government. Others are assuaged when central banks buy government debt in the secondary market but not directly. Who is right? My summary of the article by Dr. Rajan (find the link of the original article at the end) where I have used balance sheets to visualize the flow. Meanwhile, I also found a few points which I found weren't mentioned in the article. Feel free to comment on what you think about it. Click here  to read the original article. 

Impact of Openness on CO2 emissions in China

The study explores the effect of trade and FDI contributed to CO2 emissions in China from 1981-2014. It finds that trade, mainly exports, and FDI had significantly led to higher emissions. Thereby it finds evidence in support of Pollution Haven Hypothesis.

Impact of Diesel Price Deregulation on asymmetricity of Exchange rate Pass-through to inflation

India is a net importer of energy, with High-Speed-Diesel playing a central role in India’s energy dynamics. Due to this, diesel prices were passed in a controlled manner and distributed asymmetrically between favourable and unfavourable shocks.
