For the majority of people, media coverage is the primary source of information about important issues of the day. I explore media coverage, particularly in relation to climate change, in the three chapters of this thesis. The first chapter analyzes the divergence between the views of the scientific community and the public through the lens of media capture. I develop an objective measure of the tone of climate change coverage by creating an index which uses phrase frequency analysis to compare newspaper text with the UN's IPCC reports and the Heartland Institute's skeptical response. The index captures the extent to which newspaper text aligns with each report, classifying text that shares more language with the IPCC report as being more environmental. Using the index and panel data on advertising spending, I implement an instrumental variables strategy and find that advertising from carbon-emitting industries increases the prevalence of skepticism and lowers the quantity of coverage of climate change in US newspapers. The second chapter proposes a model that explores the issue of media bias. The model complements the literature that discusses demand-driven (Gentzkow and Shapiro, 2006) and supply-driven (Baron, 2006) bias by showing that biased coverage can arise when neither media outlets nor consumers are biased. Instead, the bias in the model I present evolves from the premise that information is costly for media outlets to acquire. The third chapter presents an empirical analysis of competition among newspapers. Newspapers compete by taking a homogeneous input -- the news that is available to report on -- and producing a differentiated output: the coverage they provide. I study the mechanics of this process by analyzing coverage of climate change in British newspapers during the period 2006-2015. Using Latent Dirichlet Allocation to classify newspaper articles by topic, I compare the prevalence of topics across newspapers. Newspapers tend to cover the similar topics at a given time, but are able to differentiate themselves based on which topics they cover most. If a newspaper usually provides extensive coverage of a topic related to climate change, it will increase coverage more in response to a news story involving that topic.
