This paper studies the innovation dynamics of an oligopolistic industry. The firms compete not only in the output market but also by engaging in productivity enhancing innovations to reduce labor costs. Rent sharing may generate productivity dependent wage differentials. Productivity growth...

This paper argues that drugs are expensive not because of a lack of competition among research-based pharmaceutical companies, but because of a lack of competition in the drug approval process. Lack of competition in the drug approval process has led to exceedingly high drug development costs....

This Paper studies the inter-temporal problem of a monopolistic firm that engages in productivity-enhancing innovations to reduce its labour costs. If the level of wages is sufficiently low, the firm's rate of productivity growth approaches the rate of wage growth and eventually the firm reaches...

This paper investigates the R&D allocation and output decisions of a profit-maximising monopolist developing a science-based family of products or processes. A comparison of the numerical solution for a model with incremental product innovation, and that with incremental process innovation,...

In this paper, we argue that lower prices for pharmaceuticals can be achieved by fostering a new type of competition in the pharmaceutical industry. Lower drug development costs, and hence prices, can be brought about by abolishing national drug administrations and replacing them with private...

This discussion paper resulted in a publication in the <I>Journal of Economic Dynamics and Control</I> (2013), 37(12), 2729-2754.<P> Existing models of R&D are not easily reconciled with four observable aspects of R&D: initial technologies ('ideas') need to be developed further, only a minority of initial...</p></i>

When it speaks of Schumpeterian hypothesis we refer to the close relationship that exists between the degree of innovation and market structure. The entrepreneur represented by Schumpeter's is strongly creative and innovative to condition to be able to get e/o to maintain a market power, and...

We consider a two-sided market model with a monopolistic Internet Service Provider (ISP), network congestion sensitive content providers (CPs), and Internet customers in order to study the impact of Quality-of-Service (QoS) tiering on service innovation, broadband investments, and welfare in...

Existing models of R&D are not easily reconciled with four observable aspects of R&D: initial technologies (ideas) need to be developed further, only a minority of initial ideas are successfully brought to the market, production and process innovations take place simultaneously (whereby,...

Destructive Creation is the deliberate introduction of new, perhaps improved generations of durable goods that destroy, directly or indirectly, the usage value of units previously sold inducing consumers to repeat their purchase. This paper discusses this practice by a single seller in an...
