Annex 5: Key Features of the Ug<strong>and</strong>a Overlapping Generations (OLG) Model<br />
Basic features:<br />
• Individuals live for (at most) three periods: childhood (period t-1), adulthood (period t) <strong>and</strong> retirement (period t+1).<br />
• The economy produces a homogenous market good that can be either consumed in the period it is produced or stored to yield<br />
capital at the beginning of the following period.<br />
• Each individual is endowed with one unit of time in childhood <strong>and</strong> adulthood, <strong>and</strong> zero units in old age. In adulthood time is<br />
allocated inelastically to market work.<br />
Modeling features:<br />
Individuals<br />
• At the beginning of adulthood in t, each individual produces n t<br />
children, who depend on their parents for consumption <strong>and</strong> any<br />
spending associated with schooling <strong>and</strong> health care.<br />
• Raising a child also involves a cost of (0,1) of the individual’s net income. Consumption of children is subsumed in the<br />
individual’s consumption.<br />
• Wages is the only source of income as all individuals work in middle age (second period of life).<br />
• Savings can be held only in the form of physical capital.<br />
• Agents have no other endowments, except for an initial stock of physical capital at t = 0, which is the endowment of an initial<br />
old generation. Each individual is endowed with e t<br />
units of human capital. Each unit of human capital earns an effective market<br />
wage, w t<br />
, per unit of time worked.<br />
• Assuming that consumption of children is subsumed in the individual’s consumption, the individual’s utility takes the form<br />
