We study the supply of political communication highlighting perceived threats, using the 2014 Ebola scare as a natural experiment. Analyzing Twitter posts and congressional newsletters from US House and Senate candidates, we find Republicans increased Ebola-related communication, emphasizing negative sentiment and links to immigration. This response was strongest in safe Republican seats, consistent with base signaling. The supply side was active, not reactive: the Republican response did not vary with proximity to diagnosed cases despite concentrated voter anxiety, politician tweets predicted public Ebola activity but not vice-versa, and more intensive messaging correlated with better elect..

This paper studies the joint behavior over time of the mean and dispersion of U.S. import tariff rates across goods at the HTS 6-digit level, as well as the macroeconomic consequences of the shocks that drive these two moments. We document that the cross-sectional mean and the cross-sectional dispersion of import tariffs move closely together over time. Using a state-space model, we find that both are driven primarily by common shocks, while mean- and dispersion-specific tariff shocks play a negligible role. Thus, effectively, there are no separate mean-tariff shocks or tariff-dispersion shocks; there are only mean-dispersion tariff shocks. These common shocks account for a sizable share of ..

One of the most comprehensive fiscal policies to improve diet was adopted by the Navajo Nation; the Healthy Diné Nation Act (HDNA) of 2014-15 consists of two parts: 1) an exemption from sales tax for healthy foods and beverages; and 2) a tax increase on unhealthy foods and beverages. Together, they create a price wedge of 7-8% between healthy and unhealthy foods. We estimate difference-in-difference models and event studies that estimate the effect of the HDNA on a variety of health conditions relating to diet and weight for newborns and mothers which are recorded in birth certificate data. We find no evidence that the HDNA improved these outcomes; our estimates are precise enough to rule o..

Most LLM benchmarks rank models on their ability to automate work tasks. In practice, however, models are often used to assist other (human or LLM) agents. The question that drives model selection is therefore not only which model produces the best output, but which model most improves the work of another (weaker) agent. We introduce a unified framework that evaluates the capability of models to automate and augment another agent's performance. Across seven economically grounded real-world tasks, an assistant model writes assistance text for a standardized lower-capacity worker model, which produces the deliverable. In automation mode, the assistant produces the output directly. Outputs are ..

Amid renewed policy interest, the academic literature on place-based programs has expanded dramatically in recent years. In this essay, we review recent theoretical and empirical work in an effort to assess when and why place-based job creation policies succeed or fail. Drawing on theory, we describe key dimensions on which place-based programs vary and discuss evidence on the consequences of different design choices. We conclude with several lessons for the next generation of place-based programs.
