F d li t f i htFeudalism as a system of rights.

The acts constituting the feudal contract were gcalled homage and investiture. The tenant or vassal knelt before the lord surrounded by his court (curia), placing his folded hands between those of the lord and thus became his ‘man’those of the lord, and thus became his man (homme, whence the word homage). … The lord in turn responded by ‘investiture’, handing to his vassal a banner, a staff, a clod of earth, a charter, or other symbol of the property or office conceded, the fief (feodum or Lehn) as it was termed …. This was the free and honourable tenure characterized by military service but thetenure characterized by military service, but the peasant, whether serf or free, equally swore a form of fealty and was thus invested with the tenement he held of his lord. The feudal nexus

thus created essentially involved reciprocity.

Early medieval agricultureEarly medieval agriculture.

Traditional individualistic subsistence agriculture. Shared common “wastes” with little

common-pool pressure. “Sedentary pastoralism” takes precedence

over cultivation of arable. Eventually: communal control over

common-field grazing.

S tt i l l tiScattering: early explanations.

Size of plow team Size of plow team. Land in proportion to contribution. But scattering observed even when light plow used.

Desire for equality. But there were many inequalities among peasants.

Partible inheritance Partible inheritance. But England had primogeniture.

Problems with the risk h th ihypothesis.

Landlords provide de facto “charity.” We don’t see less scattering in villages with

landlords.a d o ds

Scattering stabilizes relative peasant outputs, but doesn’t insure aggregate output against h kshocks. And if scattering is costly, it increases chance of

starvation.

Fenoaltea: optimal allocation of labor Fenoaltea: optimal allocation of labor. Optimal farm management would assign

labor to different parts of the fields at different times. But central direction implies costly monitoring Ownership of scattered strips preserves

incentives. Scattering protects the individual against

the system.y Collective activities (especially harvesting)

capacity constrained – not all can be harvested. Without scattering, some peasant fields would

22

never be harvested at all in some years.
