Voting for a founding: Testing the effect of economic interests at the federal convention of 1787

Previous work measuring the voting patterns of the delegates to the Constitutional Convention largely focused on either individual delegate positions for a handful of key votes or on state delegation positions for a far broader set of votes. We remedy this limitation by modeling the key first two months of the Convention including both some individual-level and all delegation-level voting, while simultaneously estimating the effect of various economic interests on that voting, controlling for various cultural and ideological factors. The findings suggest that economic factors mattered a great deal at the Convention. The effect of such interests vary however by the dimension of debate-representation, national institutional design, or federalism. We conclude that economic interests exerted a powerful influence on the deep structure of voting at Convention, though not consistently by issue or dimension. Specific interests only mattered on specific dimensions.
