For a French village, we reconstitute most families and build accurate measurements of economic conditions. Combined with marriage contracts (systematic in this writtenlaw area), we are able to control for wealth, Stem households and social status of father and husband for a representative sample. We clarify the operation of the EMP system: bad economic conditions resulted in later female age at marriage, which had positive consequences, such as fewer children, adjusting the population level, and a smaller age difference between spouses, allowing greater agency for women within the couple. A supposed positive effect on human capital is not significant.
