Consequences of social trust are comparatively well studied, while its societal determinants are often subject to debate. This paper studies both in the context of Catalan attempts to secede from Spain: First, we test whether Catalonia enjoys higher levels of social capital that it is prevented from capitalizing on. Second, the paper examines whether secessionist movements create animosity and political divisions within society that undermine trust. Employing the nine available waves of the European Social Survey for Spain, we only find weak indications that social trust levels are higher in Catalonia than in the rest of the country. Interestingly, we further find testimony of a purely transient "exuberance effect" after secession became a real option, indicating that the long‐run evolution of social trust may best be thought of as a stable punctuated equilibrium.

A large body of literature has examined the impact of the horizontal market structure on the tax incidence on consumers. However, the extent to which the vertical market structure affects the tax pass-through—which might be particularly relevant in the presence of the double marginalisation problem—is an unexplored question. Using a confidential dataset of gas station contracts with a major Spanish refiner, in combination with their retail fuel prices and characteristics, we document that the pass-through of a tax on prices is about 38% higher in vertically integrated gas stations than in independent ones. Our estimates allow us to assess the impact on government revenue and emissions under different counterfactual market scenarios. [ABSTRACT FROM AUTHOR]
