We examine empirically cross-fertilization in the productivity growth of banks between a state and its neighboring and non-neighboring states before (1971-1977) and during (1982-1995) the interstate multibank holding company (IMBHC) deregulations, upon which, cross-border bank M&As, mainly among...

This paper presents a new mechanism through which the geography of bank deposits increases financial fragility. We document the within-bank geographic concentration of deposits -- 30% of bank deposits are concentrated in a single county. We combine this within-bank geographic concentration of...

The federal mortgage policy, the conforming loan limit (CLL), was spatially uniform before the recent financial crisis, despite heterogeneity across geography. An increased CLL leads to remarkable regional variation in declines in jumbo loan applications, exogenously increasing jumbo-lending...

We incorporate arguments from the Tiebout model into the regulatory competition equilibrium and study cross-fertilization in the productivity growth of banks between those in a state and others in this state's neighboring states. Empirically, we focus on two time periods: before (i.e.,...

The objective of this paper is to explore the transmission of non-bank capital shocks through banking networks. We develop a methodology to construct non-bank capital shocks, idiosyncratic shocks, using labor productivity shocks to large firms. We document a change in the relationship between...

This paper explores the transmission of non-capital shocks through banking networks. We develop a methodology to construct non-capital (idiosyncratic) shocks, using labor productivity shocks to large firms. We document a change in the relationship between foreign idiosyncratic shocks and...

We study the role of banks in amplifying a fiscal stimulus. Exploiting increases in US defense spending following the 9/11 attacks, we show that increased economic activity in counties exposed to the spending shock lowered non-performing loans at banks. In turn, banks increased lending to small...

This paper presents a simple, analytically solvable Chamberlinian agglomeration model. As in the canonical core-periphery (CP) model, two agglomerative forces are at work. However, the present model exhibits a 'pitchfork bifurcation' rather than the 'tomahawk bifurcation' of the CP model.
