Around 1700, Britain's Parliament established a forum where rights to land and resources could be reorganized. This venue enabled landholders and communities to exploit economic opportunities that could not be accommodated by the inflexible rights regime inherited from the past. In this essay, historical evidence, archival data, and statistical analysis demonstrate that Parliament increased the number of acts reorganizing property rights in response to increases in the demand for such acts. Tests with placebo groups confirm the robustness of our results. This evidence corroborates a cornerstone of our hypothesis, that British property rights became adaptable in the century preceding industrialization.
