Looking up the sky: unidentified aerial phenomena and macroeconomic attention

Attention to information plays a key role in recent macroeconomic analysis, yet measuring it is a challenging endeavor, most notably in terms of covering varying geographical levels and time frequencies. We propose a novel, unconventional measure of public attention, which addresses these limitations, based on individuals’ reports of Unidentified Aerial Phenomena (UAP). We document a surprising link between UAP sightings and macroeconomic conditions at the U.S.-county, state, and national levels. Controlling for weather conditions, and external influences, UAP sightings are more common in wealthier regions, but within regions the pattern is counter-cyclical. Thus, variations in attention to exceptional phenomena in the skies implicitly point at more general patterns of variations in the public attention. We further support this interpretation by a quasi-experimental design that utilizes plausibly exogenous regional variations in COVID-19 restrictions and find evidence for a causal effect on public attention. We further show that the UAP sightings measure is highly correlated with conventional measures of attention that are based on expectations data. We then apply our measure in the context of monetary policy transmission. We find that it can account for sizable regional heterogeneity in the response to monetary shocks. Higher levels of attention across U.S. regions, as well as within regions over the business cycle, substantially mitigate the effect of monetary policy.
