This paper investigates the role of output quality control in a multi agent setting with moral hazard. The principal is in charge of a team of agents who produce the output. The marketing of this output can be either a success or entail huge losses. At the time of marketing the product, the...

Until now most research in dynamic games focus on models with quadratic objective functions because of practical considerations. But in reality, all problems are not quadratic. In this paper, we solve a differential game where players have non-quadratic preferences. In particular we consider an...

We analyse the optimal pricing choice of an incumbent firm that sells a good with network externalities and is threatened by the entry of a higher quality variant. In the framework of a vertical differentiation model, we find a necessary and sufficient condition under which quality improvement...

We analyse firms’ incentives to provide two-way compatibility between two network goods with different intrinsic qualities. We study how the relative importance of vertical differentiation with respect to the network effect influences the price competition as well as the compatibility choice....

We analyze the competition between two newspapers in a vertical differentiation model where the qualities of the journals are determined endogenously in the first stage of the game. We show that when the advertising revenues per reader increase there is a critical value above which the quality...

The present note first provides an alternative formulation of the Cancian, Bills and Bergström (1995) - problem which discards the non-existence difficulty and consequently allows to consider some extensions of the TV-newscast scheduling game. The extension we consider consists in assuming that...

This paper analyses price competition under product differentiation when goods are defined in a two dimensional characteristic space, and consumers do not know which firm sells which quality. Equilibrium prices consist of two additive terms, which balance consumers’ relative valuation of...

Innovative workplace practices based on multi-tasking and ICT that have been diffusing in most OECD countries since the 1990s have strong consequences on working conditions. Available data show together with the emergence of new organizational forms like multi-tasking, the increase in the...

This paper investigates the effect of organizational and technological changes on job stability of different occupations in France. We first develop a basic matching model with endogenous job destsruction. It provides a structure to the empirical analysis, where we extensively exploit a unique...

In this paper we explain the apparent "diversification discount” of conglomerates without assuming inefficient-cross subsidisation through internal capital markets. Instead we assume that internal capital market efficiently redistributes scare resources across a conglomerate’s divisions...
