This paper develops a quality-ladder model of endogenous growth to study the interplay between in-house R&D and marketing expenditure. Although promotional activity is modelled as purely wasteful competition among firms for attention, it unambiguously fosters innovation activity of firms, and...

This paper proposes a model in which the removal of barriers to trade and factor mobility is associated with endogenous fragmentation of the value-added-chain. Fragmentation is the outcome of cost competition - the profit-maximizing choice of cost structure by monopolistically competitive firms....

High employment protection in the public sector results in strategic over-employment if government divisions compete for budgets in a dynamic setting. Bureaucrats who are interested in maximising their divisions' output employ excess labor, since this induces the sponsor to provide complementary...

Employment protection systems are known to generate significant distortions in firms`hiring and firing decisions. We know much less about the impact of these regulations on worker effort. The goal of this paper is to fill in this gap and in particular to assess whether the provision of...

We consider a firm that is subject to employment protection laws that limit the firm's ability to fire labor. In particular, we suppose that though a firm which shuts down can fire all its workers, it may fire no fewer. Compared to a firm that is subject to no employment protection, a firm...

We integrate individual power in groups into general equilibrium models. The relationship between group formation, resource allocation, and the power of specific individuals or particular sociological groups is investigated. We introduce, via an illustrative example, three appealing concepts of...

Corporate success stories often resemble a snowball. We show how initial luck in hiring talented people, the resulting technological advantage, superior corporate culture, and status-seeking by workers and by consumers can make small initial differences generate large differences over time.

A firm actively manages its rival's beliefs by disclosing and concealing information on the size of its process innovation. The firm's disclosure strategy results from the trade-off between two effects on product market incentives. First, the firm's competitor learns that the firm is efficient,...

This paper studies R&D investment decisions of a firm facing the threat of new technology entry and subject to technical uncertainty. We distinguish four scenarios: inevitable entry, entry deterrence, entry blockade, and non-credible entry threat. The entry threat stimulates the incumbent to...

This paper presents a dynamic model of a competitive R&D and production duopoly subject to knowledge spillovers. Two asymmetric firms operate for a limited period of time and dispose their knowledge capital in the end. Both firms and the social planner prefer the R&D-cooperative strategy over...
