2. Cycles of Fire? Politics and Forest Burning in Indonesia

Abstract

This paper examines the link between electoral incentives and environmental degradation by exploiting a satellite dataset on 107,000 forest fires and 879 asynchronous district elections in Indonesia. Fires represent a cheap but illegal means of converting forested land to other uses, but they risk burning out of control and creating substantial negative environmental externalities. We find a significant electoral cycle in forest fires. Ignitions and area burned decline during election years but steeply increase in the year after. The results suggest that politicians may suppress this activity at times when it might particularly dent their electoral chances.

4. When Celebrities Speak: A Nationwide Twitter Experiment Promoting Vaccination in Indonesia

Abstract

Celebrity endorsements are often sought to influence public opinion. We ask whether celebrity endorsement per se has an effect beyond the fact that their statements are seen by many, and whether on net their statements actually lead people to change their beliefs. To do so, we conducted a nationwide Twitter experiment in Indonesia with 46 high-profile celebrities and organizations, with a total of 7.8 million followers, who agreed to let us randomly tweet or retweet content promoting immunization from their accounts. Our design exploits the structure of what information is passed on along a retweet chain on Twitter to parse reach versus endorsement effects. Endorsements matter: tweets that users can identify as being originated by a celebrity are far more likely to be liked or retweeted by users than similar tweets seen by the same users but without the celebrities' imprimatur. By contrast, explicitly citing sources in the tweets actually reduces diffusion. By randomizing which celebrities tweeted when, we find suggestive evidence that overall exposure to the campaign may influence beliefs about vaccination and knowledge of immunization-seeking behavior by one's network. Taken together, the findings suggest an important role for celebrity endorsement., Comment: 55 pages, 13 tables, 6 figures

17. Do Celebrity Endorsements Matter? A Twitter Experiment Promoting Vaccination in Indonesia.

Abstract

Do celebrity endorsements matter? And if so, how can celebrities communicate effectively? We conduct a nationwide Twitter experiment in Indonesia promoting vaccination. Celebrity messages are 72% more likely to be passed on or liked than similar messages without a celebrity's imprimatur. In total, 66% of the celebrity effect comes from authorship, compared to passing on messages. Citing external medical sources decreases retweets by 27%. Phone surveys show that those randomly exposed to messaging have fewer incorrect beliefs and report more vaccination among friends and neighbours. The results can inform public health campaigns and celebrity public service more generally. [ABSTRACT FROM AUTHOR]

49. Should Aid Reward Performance? Evidence from a Field Experiment on Health and Education in Indonesia. NBER Working Paper No. 17892

Author

National Bureau of Economic Research, Olken, Benjamin A., Onishi, Junko, and Wong, Susan

Abstract

This paper reports an experiment in over 3,000 Indonesian villages designed to test the role of performance incentives in improving the efficacy of aid programs. Villages in a randomly-chosen one-third of subdistricts received a block grant to improve 12 maternal and child health and education indicators, with the size of the subsequent year's block grant depending on performance relative to other villages in the subdistrict. Villages in remaining subdistricts were randomly assigned to either an otherwise identical block grant program with no financial link to performance, or to a pure control group. We find that the incentivized villages performed better on health than the non-incentivized villages, particularly in less developed areas, but found no impact of incentives on education. We find no evidence of negative spillovers from the incentives to untargeted outcomes, and no evidence that villagers manipulated scores. The relative performance design was crucial in ensuring that incentives did not result in a net transfer of funds toward richer areas. Incentives led to what appear to be more efficient spending of block grants, and led to an increase in labor from health providers, who are partially paid fee-for-service, but not teachers. On net, between 50-75% of the total impact of the block grant program on health indicators can be attributed to the performance incentives.
