The label “Keynes-Negishi equiibria” is attached here to equilibria in a monetary economy with imperfectly competitive product and labor markets where business firms and labor unions hold demand perceptions with kinks - as posited in Negishi’s 1979 book Microeconomic Foundations of...

It is now well known that in models with imperfect competition the choice of the normalization rule may have real effects. The scope and the reason of this result are investigated. I first show that a clear distinction must be made between imperfect competition based on quantity versus nominal...

The paper studies equilibria for economies with imperfect competition and non-convex technologies. Following Negishi, firms maximise profits under downward-sloping perceived demand functions. Negishi’s assumptions, in particular the assumption of a single monopolistic competitor in each...

This paper examplifies in a simple general equilibrium model the important role played by the monetary policy when there are strategic interactions bearing on nominal variables. It shows that the common notion of money neutrality is misleading in this context. Indeed, linear homogeneity in the...
