This study examines how changes in political leadership and rising U.S. polarization flow through societal culture to corporate culture. Using quasi-experimental methods, we find that executives adjust culture messaging in earnings calls on extensive and intensive margins across varying political contexts. These changes follow two pathways: under political alignment, executives emphasize their firm’s culture, motivated by pride; and under political misalignment, executives reduce cultural messaging—particularly innovation, quality, and respect—due to lower perceived growth opportunities. Additional tests reveal these changes reflect strategic communication rather than fundamental cultural changes. Our findings highlight how cultural messaging varies with political context.

We study the dynamics of cash-and-carry arbitrage using the U.S. crude oil market. Sizable arbitrage-related inventory movements occur at the New York Mercantile Exchange (NYMEX) futures contract delivery point but not at other storage locations, where instead, operational factors explain most inventory changes. We add to the theory-of-storage literature by introducing two new features. First, due to arbitrageurs contracting ahead, inventories respond to not only contemporaneous but also lagged futures spreads. Second, storage-capacity limits can impede cash-and-carry arbitrage, leading to the persistence of unexploited arbitrage opportunities. Our findings suggest that arbitrage-induced inventory movements are, on average, price stabilizing.
