Suppose a household consists of two agents, indexed by i=1,2. Let each agent i have

a utility function given by

U_i(l_i, c) = ln(c) + (1-)ln(l_i), i = 1, 2,

where is the preference parameter of each agent, l_i is i's leisure consumption, and c

is the household consumption (as public good). The total amount of time available to

each agent is 1, so the time constraint is given by 1 = l_i + h_i, where h_i is work hours

for i. The wage rate of agent i is given by w_i. Non-labor income is Y = y1 +y2, with y_i

denoting the non-labor income of agent i. Suppose also each agent behaves non-

cooperatively.
