Nobel Prize 2021 for Economics

Business Line

GS 3: Economy


  • David Card, Joshua Angrist and Guido Imbens were the 2021 Nobel Prize winners in Economics for their contribution in the field of labour economics.
  • Their work is based on cause-and-effect related issues and is particularly relevant in public policy.


  • They have provided us with new insights about the labour market and shown what conclusions about cause and effect can be drawn from natural experiments.
  • Their approach has spread to other fields and revolutionised empirical research.
  • David Card has analysed how minimum wages, immigration and education impact the labour market.
  • One of the significant findings of this research was that “increasing the minimum wage does not necessarily lead to fewer jobs”.
  • It also led to the understanding that “people who were born in a country can benefit from new immigration, while people who immigrated at an earlier time risk being negatively affected”.
  • It also illuminated the role of resources available in school in shaping the future of students in the labour market.
  • Joshua Angrist and Guido Imbens were rewarded for their “methodological contributions” to the research tool.
  • Their work demonstrated “how precise conclusions about cause and effect can be drawn from natural experiments”.

Key questions in labour economics answered by their work:

Do more years of education lead to higher future income?

  • Their experiments showed that students who studied more earned higher income.
  • This study cannot be done with a fixed set of respondents.
  • Understanding the socio-economic conditions and observing the target populations over a time period is important, which the observational data approach helped.

Does an increase in minimum wage lead to lower employment?

  • This is a critical question for the labour market to find a balance.
  • The labour wants a higher wage. But companies like to be selective in paying higher wage to the more efficient.
  • David Card’s analysis shows that employment does not suffer with an increase in minimum wage.
  • Because, when minimum wage increases labour tends to become more efficient which helps the organisation to increase output.
  • So, labour costs do not get burdensome.

Do immigrants create problems to the local labour force?

  • This was one of the key issues in the US that came up especially under the Trump regime.
  • It was alleged that immigrants tend to take over the jobs of the local population.
  • David Card’s analysis shows this does not necessarily happen, and it depends on the level of work.


  • The larger question is whether corporates can wait for long to get these results before launching a product.
  • Often the product is differentiated and cannot be compared with stories of other companies.
  • So, such natural experiments tend to work better for government-driven programmes where experiences from the past provide signals for the future.
  • In other words, from the public policy point of view, these theories are very relevant and more likely to be pursued.

GS 2: Polity


  • Former Chief Election Commissioners (CEC) have raised a range of concerns, from maintaining secrecy of ballots to bringing political parties on board around the idea of online voting and remote voting.
  • This came at a time the Telangana State Election Commission is set to carry out an e-voting experiment and the Election Commission of India, too, is exploring remote voting.


  • E-Voting/Remote Voting will allow electors to vote from faraway cities without going to the designated polling station of their constituencies.
  • The voters will have to reach a designated venue during a pre-decided period of time to be able to use this facility.
  • The IIT-M is developing a system for two-way remote voting in a controlled environment using blockchain technology.
  • It would entail voter identification and authorisation on the Electoral Registration Officer Network (ERO Net) using biometric data and web cameras for authentication, followed by a blockchain-based e-ballot generation, which would convert into a vote once the hash code would be generated on its execution.
  • The encrypted remote votes cast would once again be validated at the pre-counting stage to ensure that they have neither been decrypted nor tampered with or replaced.

International perspective:

  • Countries such as the USA, Argentina, Russia, Estonia, Thailand and South Korea in the past have utilised the blockchain methods for conducting voting processes for their citizens, with a fair share of positives and negatives deriving consequentially.

India’s position:

  • India has had a positive response towards exploring the implementation of blockchain networks across several sectors, including election systems.
  • The foremost example is that of the Telangana government, which aims at implementing an experimental run towards an e-voting idea.
  • The ECI had used a one-way electronic system for service electors for the first time in the 2019 Lok Sabha elections.
  • The postal ballots were transmitted electronically to the service electors, which led to an increased turnout of 60.14%.
  • In 2020, the Election Commission conducted several discussions and demonstrations with various state governments, policy think tanks, and private industry stakeholders to explore the idea of a nationwide remote blockchain election system.
    • In February 2020, it had collaborated with the Indian Institute of Technology, Madras (IIT-M)


  • Breaks the geographical barriers
  • More Flexible for voters
  • Inclusion of eligible voters and increase turnout in voting numbers
  • It will be promoting security towards the recording of votes as opposed to physical tampering.
  • Efficiency in counting votes
  • Minimising errors


  • Reliability  
    • O.P. Rawat, who was the CEC in 2018, agreed that if the security of EVMs that are standalone devices was questioned from time to time, then Internet-based voting would have even more issues and critics.
  • It might be attacked by hackers which would distort the final result.
  • Issues of Privacy

Way Forward:

  • It can be stated that blockchain technology in elections is a double-edged sword and one needs to ponder upon whether there are additional complications that arise out of the same.
  • The existing laws will have to be amended to undertake that gigantic exercise which also requires political consensus.
  • The issue of individual privacy and data protection in the course of collation, authentication of personal data for blockchain elections require significant deliberation.
    • There would be process changes and wider consultations with all the stakeholders including political parties before the facility is rolled out.
  • In order to ensure an effective blockchain election system, two points stand pertinent:
    • Cryptography involved blockchain election system should ensure a tamper-free record, display, and calculation of data involved in the election.
    • Policymakers should pay attention to the aspect of data protection and privacy in the course of authenticating a valid voter via biometric systems.
