Contrast these equations with their counterparts for the Keynesian equilibrium. 71) n i=1 ai, j Yi pi i=1 rj . 72) Consumers with logarithmic preferences will set budget shares to utility weights: pi Yi = gi Z .
I will show that this externality is the source of Keynesian unemployment. 31) and exploit the logarithmic structure to write utility as a weighted sum of the logs of capital and labor used in each industry, and of the externality terms that depend on the log of 1 − L¯ .

Each firm recruits workers in a search market by allocating a measure Vi of workers to recruiting. The total measure of workers, L i , employed in industry, i, is L i = X i + Vi . 15) Each firm takes parametrically the measure of workers that can be hired, denoted q, and employment at firm i is related to Vi by the equation L i = q Vi . 17) a i,m Yi ≤ Ai K i,1i,1 K i,2i,2 . . 19) L i = q Vi . 21) is defined as 1 . 23) a a i,m K i,1i,1 K i,2i,2 . .
