Abstract
This paper studies the response of household inflation expectations to television news coverage of inflation. We analyze news data from CNN, Fox News, and MSNBC alongside a daily measure of inflation expectations. Using a local projection instrumental variables approach, we estimate the dynamic causal effect of inflation news coverage on household inflation expectations at a daily frequency. Increased media coverage of inflation raises expectations, with effects peaking within a few days and fading after approximately 10 days. Additionally, we document a key nonlinearity: release days with positive CPI surprises—i.e., inflation exceeding market expectations—lead to stronger expectation responses than release days with negative surprises.

Is Economics a Failure?
Rather than ending with “economics is broken,” Alexander Rosenberg’s deliberately provocative book 'Blunt Instrument' argues that “economics is useful for a different reason than economists often say.” That is a serious and worthwhile thesis.
Locke, Meet Claude
The concern is not regulation per se. It is a regulation that outruns its justification by arriving before the evidence, foreclosing the technology before its benefits are understood, and insulating the powerful from competition that would otherwise discipline them. That is the pattern worth resisting.
