An extensive empirical literature indicates that, even without formal intellectual property rights, innovators enjoy a variety of first-mover advantages and that `imitation' is itself a costly activity. There is also accumulating evidence that an `open' approach to knowledge production can...

We examine pollution-reducing R&D by a monopoly firm producing a dirty product. In a dynamic framework with hyperbolic discounting, we establish conditions under which the Porter hypothesis goes through, i.e. environmental regulation increases R&D, thus reducing pollution, as well as increasing...

A firm's strategy typically is defined in terms of its position in the industry or landscape that operates in and the competitive advantage of the firm on that landscape. This competitive advantage, in turn, derives from a combination of assets (what the firm owns) and capabilities (how the firm...

This paper is an initial exploration of the determinants of open source project success as measured by project popularity. We simultaneously model the impact of project-specific characteristics on project popularity, and the impact of intended users and choice of operating system on the choice...

This paper investigates the optimal management of supply disruptions by a manufacturer who uses order inflation and/or investments in process reliability when contracting two risk-averse suppliers. We consider that these investments can be subject to moral hazard. Technically we solve a...

In this paper we provide a generalization of the standard models of the diffusion of a new product. Consumers are heterogeneous and risk averse, and the firm is uncertain about the demand curve: both learn from past observations. The attitude towards risk has important effects with regard to the...

A major consequence of the Internet era is the emergence of complex “platforms” that combine technology and process in new ways that often disrupt existing industry structures and blur industry boundaries. These platforms allow easy participation that often strengthens and extends network...

A Bayesian decision maker is choosing among two alternatives with uncertain payoffs and an outside option with known payoff. Before deciding which alternative to adopt, the decision maker can purchase sequentially multiple informative signals on each of the two alternatives. To maximize the...

We study how seller exit and continuing sellers' behavior on eBay are affected by an improvement in market transparency. The improvement was achieved by reducing strategic bias in buyer ratings. It led to a significant increase in buyer satisfaction with seller performance, but not to an...

We provide elementary insights into the effectiveness of certification to increase market transparency. In a market with opaque product quality, sellers use certification as a signaling device, while buyers use it as an inspection device. This difference alone implies that seller-certification...
