Identifying Reaction Functions in a Differential Oligopoly Game with Sticky Prices

We investigate the issue of strategic substitutability/complementarity in a Cournot differential game with sticky prices. We show that first order conditions do not produce instantaneous best reply functions. However, we identify negatively sloped reaction functions in steady state, with the open-loop best reply being flatter than its closed-loop counterpart. JEL classification: C73, D43, D92, ...

Advertising in a Differential Oligopoly Game*

We illustrate a differential oligopoly game where firms compete à la Cournot in homogeneous goods in the market phase, and invest in advertising activities aimed at increasing consumers’ reservation price. Such investments produce external effects, characterizing the advertising activity as a public good. We derive the open-loop and the closed-loop Nash equilibria, and show that the properties ...

Sticky Demand vs. Sticky Prices

Sticky demand – sticky nominal spending – acts as a substitute for sticky prices. In an inventorytheoretic model of the demand for money, monetary injections are offset by endogenous movements in velocity that keep nominal spending flat. When embedded in a sticky price model, this reduces the model’s reliance on implausibly large amounts of exogenous stickiness. For example: 6 months asset mark...

Sticky Prices and Indeterminacy

The aim of the present paper is to analyze the link between price rigidity and indeterminacy. This is done within a cash-in-advance economy from which we know that it exhibits indeterminacy at high degrees of relative risk aversion. I Þnd that price stickiness reduces the scope of these sunspot equilibria: sluggish price adjustment requires degrees of relative risk aversion compatible with inde...
