Policies should be based on experiments, not income; changing behaviour is more effective: Prof. Abhijit Banerjee

Nobel laureate and economist Prof. Abhijit Banerjee, who received the 2019 Nobel Prize in Economics for his experimental and innovative approach to reducing global poverty, on Monday said that solutions to complex problems like poverty and hunger do not come from grand pronouncements, but from ground-level experiments and micro-level policy reforms.

He emphasised that policymaking today should be based on concrete evidence, not “assumptions.”

On Monday, Prof. Abhijit Banerjee delivered a lecture at the Malviya Auditorium of Lucknow University at an event organised in collaboration with the Mahindra Sanatkada Lucknow Festival. His lecture focused on the second edition of his previously published book, “Poor Economics: A Radical Rethinking of the Way to Fight Global Poverty.”

In his lecture, Prof. Abhijit Banerjee spoke in detail about the five main pillars affecting poverty, nutrition, microcredit, education, poverty traps, and the power of small interventions.

He explained that field experiments conducted in 147 countries have shown that the assumption that nutritional levels automatically improve with increasing income is incorrect. According to him, bringing about positive changes in people’s priorities and behaviour is more effective than simply increasing income.

Regarding education, he said that overly ambitious curricula and rigid teaching methods hinder real learning. Citing experiments like “teaching at the right level” at the primary level, he argued that if children are taught according to their existing abilities, basic skills like reading and mathematics develop rapidly. He stressed the need to relax this “tyranny” of the curriculum.

Speaking on microfinance, Prof. Abhijit Banerjee clarified that microfinance is not a miracle solution. While it helps some people expand their businesses, it does not provide a permanent path out of poverty. He also highlighted that lack of access to credit often traps families in a vicious cycle of poverty. In such cases, programmes that combine productive assets with technical training, such as the model adopted by BRAC (Bangladesh Rural Advancement Committee), have proven effective in leading extremely poor families towards self-employment.

On microfinance, he stated that although microfinance institutions have expanded rapidly over the last 10 to 15 years, they still remain out of reach of the median person, and only the top 5% are able to gain from it. He added that while microfinance leads some of the beneficiaries to expand their businesses, it does not appear to fuel an escape from poverty based on those small businesses.

He attributed policy failures to three ‘I’s—intuition, ideology, and inertia—and stated that relying solely on good governance or trade policy is not sufficient.

Concluding his address, he said that what is needed today is attention to the “plumbing,” that is, the finer details of policy implementation. During the question-and-answer session, he also said that focusing on the local level rather than broad frameworks yields better results, and that education and health should be given top priority.

His lecture was followed by a round of questions and answers where he addressed key questions concerning the Indian economy. He said that focusing on grassroots rather than on the broad parameters could give better results, as well as expressed his concern that knowlege economy is under threat from artificial intelligence. He suggested that everybody should be given a fair chance in life, and the quality of education and healthcare should be the central focus.
