Marriage may not always be as romantic as it appears. Especially if you ask economists.
Rosenzweig & Stark (1989) show that in rural India marriages sometimes act as a mutual insurance systems for family members. This is because in rural towns income is often based on agriculture, which is dependent on weather. Thus, families live more distant from one another so as to reduce the correlation between rainfall (or other factors, like political turmoil, etc). If something happens in one place (e.g. flood), then at least the other place will most likely still be OK. This means that the other place can send remittances to the worse-off family members (‘interhousehold financial transfers’) to ensure financial stability, in essence pooling risk.
Not sure how relevant this currently is…but still it’s an interesting thought!
