Case breakdown: Movie Go Goa Gone

The scene that you saw shows Luv (played by Vir Das) and Hardik (played by Kunal Khemu) planning to attend a rave party. They are very excited about the party and start checking the amount of money available with them. Luv discovers a small amount available with him, enough to buy two beers. While the amount left with Hardik is only enough to buy a cigarette.

In this blog, Learning Perspectives will explore the meaning of Purchasing power.

What is Purchasing Power?

Simply stated, purchasing power means amount of goods and services that can be obtained with a given currency. It is also the value of currency which is expressed in terms of how many goods and services can be purchased with a single unit of currency. It can be referred to as buying power of the currency. Currency is the form of money that is used in the circulation as a source of exchange. (Rupees in India, Euro in Europe etc.)

Similar to the scene that we saw, how Luv and Hardik are checking the amount of money they are left with. They are figuring out what exactly can they buy with this money.

Let’s assume income of Luv remains the same but price level increases, purchasing power of the income falls. If Luv’s real income increases then his purchasing power would also increase. Real income means income adjusted for inflation. Inflation is the general rise of price level in the economy which leads to lower purchasing power.

Thia movie is set in 2013 but if this movies was set 1993. Purchasing power of Luv and Hardik would be very different. With the same amount of money available, they could have purchased, maybe 4 beers and 2 cigarettes. This indicates that currency had a greater purchasing power during 1993. To sustain a good lifestyle, they will have to earn higher income in 2033, as the inflation would rise.

What is Purchasing Power Parity?

Purchasing power parity (PPP) is another concept in economics which compares two countries’ currencies by removing the differences the price level between countries across a basket of goods. This indicator is measured in terms of national currency per US dollars.

Gross Domestic Product (GDP) and income levels across countries are often compared by converting national data into a common currency using exchange rates.

According to a recent report of OECD (2016-2020) on PPP, indicates purchasing power parity of various countries. Comparing India, China, Korea and Singapore, one was able to find PPP in these countries.

India- 21.990

China- 4.186

Korea- 861.824


These numbers indicate purchasing power parity (PPP) which means that basket of goods that can be purchased in different countries for US dollars. A basket of good in India would cost $21.99 and the same basket of good in China would cost $4.186.
