This paper operates under an opposite assumption and, instead, argues that the Kentucky-Ohio border is an ideal test case for the null hypothesis that the institution of slavery per se had no significant economic effects. Kentucky and Ohio counties tracing the Ohio River are composed of the same soil and face similar weather conditions (Blanford, 2001; Barnhisel, 2001; Foster, 2001). Both regions likewise claim the same geographical access to outside markets.
