This text offers a bottom-up view of the economy, rather than the more usual top-down. The point-of-view we will start with is that of the characters themselves - children of farmers in and around the Temit area.
People have property rights over the land they live on, but do not actually own it - their family does. Proprietorship passes through the eldest daughter. Young men move in with their wives.
Disease, violence and starvation usually ensure against overpopulation - during good years, new farmland is sometimes cleared, and new houses begin.
Thus, the "proprietor" and ultimate authority in the house is almost always the eldest woman in the household as well, although this can vary, and social situations can get complex. Her powers rest entirely in custom, not law, but consist of the ability to exile someone from family land, shunning, and whatever justice or punishment powers the family consents to (whether formally or not - if they allow her to be a tyrant, she can be a tyrant).
Generally speaking, women maintain the house, men maintain the fields. However, men perform many tasks in the house, and women perform many tasks in the fields, and there are many things with both which everyone participates in, such as midwinter cleaning and the grain harvest.
Both genders fight in the military, although women only compose about 30% or less of any typical fighting force.
Life is rough around Temit - the idea of having defenseless women is something they can ill afford - and its people, women included, are too mule-headed stubborn to be told they aren't capable of something.
Most trade at the local level occurs as barter or gift exchange. In general, gift exchange is used for cheap items or items of incalculable worth (such as rebuilding a barn), and barter is used for everything in between.
A strong gift culture exists among the people. When someone's barn falls over, the community gets together to rebuild it. When times are hard, everyone shares their bread. When youngfolk go off to war, the people put together small gifts, from new boots to a stout ax, to help them make it back. Neighbors often don't see each other for weeks at a time - when they do, they often bring by a jug of good ale, or a "little something" for a good friend. There are gifts at weddings, midwinter feasts, births, harvest and other minor celebrations.
Barter is relatively freeform, and usually covers such things as a commission to add on a section of a house, a stock of ale or beer, an ox, and so on.
Coinage is primarily used in town, and coins are more a way of "keeping score" of the underlying barter system than they are an end in and of themselves. However, prices are relatively fixed, and there is an estimated price for most things.
