英语翻译
Both these have a positive slope when pkl > 0 and a negative slope when pkl < 0.From (2),
(3) and our assumption pkkpll > p2
kl ,the first-order condition in k has a steeper slope than
that in l in absolute terms (Fig.1).From the concavity of the invention probability function
in k (pkk < 0),we have pk > 1/Y in the region to the left of the first-order condition in k and
pk < 1/Y in the region to the right.Similarly,from pll < 0,we have pl > 1/Y in the region
below the first-order condition in l and pl < 1/Y in the region above.The only equilibrium
is at X,the point where the two curves intersect each other.By examining the signs of pk and
pl at points off the equilibrium,we verify that X indeed represents a unique,stable,expected
profit-maximising equilibrium.The superscripted stars denote the joint profit-maximising
case.
