We study England between 2000 and 2011 when Internet diffusion spread rapidly and there was a high profile medical article (falsely) linking the MMR vaccine to autism. OLS estimates suggest Internet diffusion led to an increase in vaccination rates. This result is reversed after allowing for endogeneity of Internet access. The effect of Internet diffusion is sizable. A one standard deviation increase in Internet penetration led to around a 20% decrease in vaccination rates. Localities characterized by higher proportions of high skilled individuals and lower deprivation levels had a larger response to Internet diffusion. These findings are consistent with higher skilled and less\u2010deprived parents responding faster to false information that the vaccine could lead to autism.<\/jats:p>","DOI":"10.1002\/hec.4856","type":"journal-article","created":{"date-parts":[[2024,5,27]],"date-time":"2024-05-27T18:18:31Z","timestamp":1716833911000},"page":"1936-1948","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Information and vaccine hesitancy: The role of broadband Internet"],"prefix":"10.1002","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1719-2243","authenticated-orcid":false,"given":"Sofia","family":"Amaral\u2010Garcia","sequence":"first","affiliation":[{"name":"European Commission \u2010 Joint Research Center i3health\/Universite libre de Bruxelles  Brussels Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mattia","family":"Nardotto","sequence":"additional","affiliation":[{"name":"ECARES\u2014Universite libre de Bruxelles CEPR and CESifo  Bruxelles Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carol","family":"Propper","sequence":"additional","affiliation":[{"name":"Imperial College London Monash University CEPR and IFS  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tommaso","family":"Valletti","sequence":"additional","affiliation":[{"name":"Imperial College London CEPR and CESifo  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,5,27]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/jeea\/jvw013"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.3386\/w23089"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1162\/rest_a_01033"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhealeco.2011.01.009"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.2208110120"},{"key":"e_1_2_11_7_1","volume-title":"Social networks shape beliefs and behavior: Evidence from social distancing during the COVID\u201019 pandemic","author":"Bailey M.","year":"2024"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1080\/00324728.2019.1584327"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41591\u2010021\u201001487\u20103"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/s2589\u20107500(19)30136\u20100"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/hec.3937"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/hec.3645"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.3386\/w25223"},{"key":"e_1_2_11_14_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen\u20102016\u2010011092"},{"key":"e_1_2_11_15_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00148\u2010018\u20100709\u20109"},{"key":"e_1_2_11_16_1","volume-title":"Lost in the net?
