“Radio and Technology Adoption During India’s Green Revolution: Evidence from a Natural Experiment,” 2023. World Development, 161.
Abstract:
Can mass communication play a role in spurring technology adoption and productivity growth in agriculture, particularly when there are significant barriers to social learning? To answer this question, I estimate the impact of regional radio broadcasts, that included significant farm programming, on the adoption of high-yielding varieties (HYVs) of rice and wheat during the Green Revolution in India. I exploit the staggered expansion of the regional radio network to identify the impact. Using an annual district-level administrative dataset from 1966 to 1978, I find that introduction of regional farm radio broadcasts led to a large persistent increase in the adoption of HYVs of rice, a spatially heterogeneous technology less amenable to social learning. By contrast, there was at most a transient impact on the adoption of HYVs of wheat, a spatially homogeneous technology with a lot of scope for social learning. Importantly, I find that the regional farm radio broadcasts increased rice yields by 15%, a magnitude potentially large enough to justify the investments in the expansion of the regional radio network. Overall, this paper demonstrates that mass communication can indeed play a key role in diffusing profitable agricultural innovations when there are significant barriers to social learning.
“Persuading Voters to Punish Corrupt Vote-Buying Candidates: Experimental Evidence from a Large-Scale Radio Campaign in India,” (with L. Schechter) 2023. Journal of Development Economics, 160.
Abstract:
During the 2014 Indian general elections, we carried out a large-scale experiment randomizing a radio campaign highlighting the disadvantages of voting for corrupt vote-buying candidates. Official electoral data show that the radio campaign significantly decreased the vote share of parties that engaged in the most vote buying (as reported by journalists). Voter survey data show that the campaign increased the salience of corruption as an election issue and decreased voting for parties that offered gifts. From a policy perspective, we show that radio campaigns are a cost-effective method to influence voter behavior. From a measurement perspective, we show that journalist interviews can impartially identify vote-buying parties.

“Cable TV and Women’s Social Empowerment: Quasi-Experimental Evidence from Rural India”
Abstract:
Cable TV experienced a dramatic expansion in India during the 1990s and 2000s, introducing rural populations to new social norms, role models, and lifestyles. While prior studies suggest that television can influence attitudes and behaviors, its effects on women’s empowerment and social participation remain understudied in this context. I examine the impact of cable television on women’s welfare in rural India, focusing on key dimensions of empowerment, such as autonomy, decision-making, mobility, and participation in social groups. Using a difference-in-difference strategy and the two rounds of the India Human Development Survey (IHDS) in 2004 and 2011, respectively, I estimate the impacts of introduction of Cable TV on women and households in rural India. I find that introduction of Cable TV improved women’s status within households, evidenced by reductions in the acceptance of “wife-beating’’, but had limited effects on autonomy in decision-making or mobility outside the home. Notably, introduction of Cable TV significantly decreased women’s participation in formal village groups, potentially because of substitution between the two leisure activities, with negative implications for long-term social capital.

“Mass Media and Nation Building: Evidence from India,” (with S. Liu and P. Mittal.)
Abstract:
After India’s independence, the government implemented nation-building policies to unify its diverse population. A key tool in these efforts was the monopoly government-run radio, which rapidly expanded under the centralized five-year plans following a WWII lull. We leverage this phased radio expansion to study the impact of unity-promoting broadcasts and exposure to standardized languages under the national language policy. Using archival administrative data, we assess the impact on outcomes such as, self-reported linguistic identity, child naming patterns, inter-group conflicts, and electoral shifts between national and regional political parties. Additionally, we explore heterogeneous effects across regions, especially where significant pre-existing cultural and linguistic differences existed.
“The Labor Market and Innovation Impact of Elite Technical Education,” (with M. Dinerstein.)
Abstract:
We examine the private and social returns to attending an elite engineering school, Indian Institute of Technology. We leverage strict entrance exam score cut-offs used for admissions to various campuses across the country and to specific undergraduate majors, such as mechanical engineering, computer science, etc. to identify causal effects ten years after graduation. Using labor market data, we estimate private returns in terms of employment outcomes, earnings, and emigration. To assess social returns, we analyze intellectual property outputs, including publications and patents. By examining both individual and societal gains, we provide a fuller evaluation of the long-term value of elite technical education in emerging economies.
“Supporting Grassroots Reporters: Impacts on Journalistic Content,” (with P. Mittal and L. Schechter.)
Abstract:
Local journalism around the world, especially in low and middle countries (LMIC), already of low-quality is declining further. Coverage of local issues relevant to poor and vulnerable populations is often missing. Many vital community stories, such as infrastructure issues, public health hazards, and development needs go unreported due to lack of reporting incentives and support. We will study grassroots reporters in India, who face significant challenges, including low pay, demanding targets, and limited career progression opportunities, and have very low overall morale. We will conduct a randomized controlled trial (RCT) to evaluate the impact of providing structured support to the grassroots reporters, so they are better placed to credibly learn about local issues that matter. We will assess whether such support translates to a higher quantity and quality of journalistic content. Depending on the impacts on journalistic output, we can potentially assess downstream policy and welfare impacts.
