U.S. Import Tariffs in 2025: Realized Tariff Rates, Import Prices, and Local Labor-Market Effects
This paper analyzes the effect of the 2025 U.S. import tariffs on import prices and local labor-markets. To that end, we use highly disaggregated customs data to construct realized tariff rates from actual duty collections, rather than announced statutory schedules. An important contribution is that we document a large and persistent gap between the two measures, driven by within-country product reallocation, cross-country sourcing shifts, and implementation frictions. This implies that statutory rates are a poor proxy for the trade shock that firms actually faced. Using realized tariffs, we ...

Estimating Demand Shocks from Foot Traffic: A Big-Data Approach
This study leverages high-frequency foot-traffic data from SafeGraph to estimate demand shocks in customer-facing establishments across New York City’s retail, service, and health sectors. Recognizing that variations in foot traffic can arise from both unpredictable demand shocks and firm-driven strategies to attract customers, we present a theoretical framework that isolates establishment-level demand fluctuations from firm-level strategic choices. Implementing this empirically, we employ an unsupervised machine learning approach to classify establishments into distinct categories that are ...
