Bolded Info:The Navigation Laws were the most famous of the laws to enforce mercantilism. The first of these was enacted in 1650, and was aimed at rival Dutch shippers who were elbowing their way into the American carrying trade. The Navigation Laws restricted commerce from the colonies to England (and back) to only English ships, and none other.
One early attempt to quantify the economic effects of the Navigation Acts was by Thomas (1965). Building upon the previous work of Harper (1942), Thomas employed a counterfactual analysis to assess what would have happened to the American economy in the absence of the Navigation Acts.
