2A recent literature emphasizes the political economy underpinnings of economic underdevelopment. It notes that powerful constituencies, which arise for example from the pattern of land holdings in a country, can drive the development of economic institutions, and growth more generally (see, for example, Engermann and Sokoloff (2002)). Banks are clearly important economic institutions. While historians have argued that political forces have shaped banking systems (see, for example, Haber (2005a)), there has been little systematic examination of the evidence. In this paper we examine more systematically whether the constituencies or interest groups that emerge in a country as a result of the distribution of land holdings -often the earliest and most important form of wealth --can shape the development of the banking system. 1The precise channel through which constituencies or interest groups operate is also a matter of some debate. Some (see, for example, Acemoglu, Johnson, and Robinson (2005)) argue that the mediating channel is political institutions, as elite interest groups create coercive political institutions that give them the power to hold back the development of economic institutions, and hence economic growth.Others (see, for example, Engerman and Sokoloff (2003), Rajan and Zingales (2003a, chapter 6) or Rajan (2009)) argue that a divided society may be sufficient to hold back the development of economic institutions, even if political institutions are broadly egalitarian.One way to make progress on both questions (whether landed interest groups affect financial development and whether this can happen even in broadly democratic societies) is to examine patterns within broad political units such as countries or states, where political institutions are held relatively constant. To this end, we explore how the structure of banking across counties in the United States in the early part of the 20 th century was driven by the distribution of land within the county. We focus on banks because they were, and in many areas still are, the most important source of local finance, and thus are important economic institutions. Likewise, we focus on the distribution of land because it represents the distribution of agricultural wealth and interests at a time when agriculture was still a key sector in the U.S.

Why Did Landlords Restrict Credit?Clearly, large landowners may have had the money and power to influence county politics even in a flourishing democracy. But why would they want to restrict access to credit for others, especially small farmers and tenants, by limiting the spread of banks? The contemporary literature suggests a number of reasons. First, large landowners generated loanable surpluses. Formal credit institutions could be competition for their business of lending to tenants and small farmers.Second, tenants and small farmers needed credit to buy supplies from the local store. By limiting credit from alternative sources -for instance, by keeping banks out --the local merchant could lock the ...
