When countries open their financial sectors, foreign-owned banks appear to bring superior efficiency to their host markets but also charge higher markups on borrowed funds than their domestically owned rivals, with unknown impacts on interest rates and welfare. Using heterogeneous, imperfectly...

Does targeted financial development favor small firms or large ones? And how do resulting changes in the distribution of firm size affect aggregate outcomes? We assess the macroeconomic implications of known stylized facts from the finance literature regarding firm size and financial frictions...

We draw on stylized facts from the finance literature to build a model where altering the relative costs of bank and bond financing changes the entire distribution of firm size, with implications for the aggregate capital stock, output, and welfare. Reducing transactions costs in the bond market...

Does the mere presence of big banks affect macroeconomic outcomes? In this paper, we develop a theory of granularity (Gabaix, 2011) for the banking sector, introducing Bertrand competition and heterogeneous banks charging variable markups. Using this framework, we show conditions under which...

It is a well known quandry that when countries open their financial sectors, foreign-owned banks appear to bring superior efficiency to their host markets but also charge higher markups on borrowed funds than their domestically owned rivals, with unknown impacts on interest rates and welfare....
