On prices' cyclical behaviour in oligopolistic markets

Lambertini, Luca; Marattin, Luigi - 2016

We revisit the discussion about the relationship between price's cyclical features, implicit collusion and the demand level in an oligopoly supergame where a positive shock may hit demand and disrupt collusion. The novel feature of our model consists in characterising the post-shock...

Market power and duration of R&D investment in a panel of Italian firms

Bontempi, Maria Elena; Lambertini, Luca; Medeossi, Erica - 2016

Studies about innovation find evidence of a positive relationship between technological advancement and firm performance, in particular when the innovative effort is continuous. This paper aims to further the analysis on the duration of R&D investment at the firm level. The contribution of this...

Coordinating R&D efforts for quality improvement along a supply chain

Lambertini, Luca - 2016

The optimal design of two-part tariffs is investigated in a dynamic model where two firms belonging to the same supply chain invest in R&D activities to increase the quality of the final product. It is shown that the replication of the vertically integrated monopolist's performance can be...

On the observational equivalence of unilateral delegation contracts in duopoly

Lambertini, Luca; Delbono, Flavio - 2015

In a Cournot duopoly, if only one firm hires a manager while the other remains entrepreneurial, the Cournot-Stackelberg equilibrium emerges, with the managerial firm as the leader. This happens under at least three different delegation schemes. We illustrate the different meachanisms driving...

Delbono, Flavio; Dipoppa, Gemma; Lambertini, Luca; … - 2015

This paper aims at providing an explanation of the observed espresso price dispersion across major Italian cities. The empirical evidence suggests a positive relationships between the average espresso price in a city and the number of coffee shops (normalized for the adult population) operating...

Strategic delegation under cost asymmetry

Delbono, Flavio; Lambertini, Luca; Marattin, Luigi - 2015

We revisit the two-stage duopoly game with strategic delegation and asymmetric technologies of Sen and Stamatopoulos (2015). We show that their conclusions are misled by the restrictive assumption that the extent of delegation to managers is restricted to a binary set. Allowing for a continuous...

On the properties of linear supply functions in oligopoly

Delbono, Flavio; Lambertini, Luca - 2015

In this note we revisit the result by Menezes and Quiggin (2012), showing that under linear supply function competition, the same Nash equilibrium results when arms choose slopes or intercepts of their supply functions. This is because the first order conditions emerging in the two strategy...
