We present evidence that shared codes, religious beliefs, ethnicity - cultural proximity - between lenders and borrowers improves the efficiency of credit allocation. We identify in-group preferential treatment using dyadic data on the religion and caste of bank officers and borrowers from a...

"Is inequality largely the result of the Industrial Revolution? Or, were pre-industrial incomes and life expectancies as unequal as they are today? For want of sufficient data, these questions have not yet been answered. This paper infers inequality for 14 ancient, pre-industrial societies using...
