The Determinants of Output Per Contributor in Open Source Projects: An Empirical Examination

Fershtman, Chaim; Gandal, Neil - C.E.P.R. Discussion Papers - 2004

Using a unique dataset we examine empirically which factors explain output per contributor in open source projects. We find that the output per contributor of open source programmes is much higher when licenses are less restrictive. Further examination suggests that the difference in output per...

Internet Security, Vulnerability Disclosure and Software Provision

Choi, Jay-Pil; Fershtman, Chaim; Gandal, Neil - C.E.P.R. Discussion Papers - 2005

In this paper, we examine how software vulnerabilities affect firms that license software and consumers that purchase … software. In particular, we model three decisions of the firm: (i) an upfront investment in the quality of the software to … software. We also model two decisions of the consumer: (i) whether to purchase the software; and (ii) whether to apply a patch. …

Competition with exclusive contracts and market-share discounts

Calzolari, Giacomo; Denicolò, Vincenzo - C.E.P.R. Discussion Papers - 2009

We study the effects of exclusive contracts and market-share discounts (i.e., discounts conditioned on the share a firm receives of the customer’s total purchases) in an adverse selection model where firms supply differentiated products and compete in non-linear prices. We show that exclusive...

Menu Costs and Asymmetric Price Adjustment

Ellingsen, Tore; Friberg, Richard; Hassler, John - C.E.P.R. Discussion Papers - 2006

We study optimal price setting by a monopolist in an infinite horizon model with stochastic costs, moderate inflation, and costly price adjustment. For realistic parameters, chosen to replicate observed frequencies of price changes, the model fits numerically several empirical regularities. In...

Functional Differentiation

Sällström, Susanna - C.E.P.R. Discussion Papers - 2009

Models of product differentiation typically assume a demand for variety. This paper derives the demand for variety in a model where a representative consumer chooses how many specialised varieties to purchase for the pursuit of different activities. In contrast with previous models this...

Price Discrimination in the Concert Industry

Courty, Pascal; Pagliero, Mario - C.E.P.R. Discussion Papers - 2009

Concert tickets can either be sold at a single price or at different prices to reflect the various levels of seating categories available. Here we consider how two product characteristics (the artist’s age and venue capacity) influence the likelihood that pop music concert tickets will be sold...

Quantity Discounts for Time-Varying Consumers

Miravete, Eugenio J - C.E.P.R. Discussion Papers - 2001

When a monopolist asks consumers to choose a particular nonlinear tariff option, consumers do not completely know their type. Their valuations of the good and/or optimal quantity purchases are only fully realized after the optional tariff has been subscribed. In order to characterize the menu of...

Advance-Purchase Discounts as a Price Discrimination Device

Nocke, Volker; Peitz, Martin - C.E.P.R. Discussion Papers - 2008

In an intertemporal setting in which individual uncertainty is resolved over time, advance-purchase discounts can serve to price discriminate between consumers with different expected valuations for the same product. Consumers with a high expected valuation purchase the product before learning...

Imperfect Tests and Natural Insurance Monopolies

Emons, Winand - C.E.P.R. Discussion Papers - 1997

This paper considers a housing insurance market in which buildings have different damage probabilities. Insurers use imperfect tests to find out about buildings’ damage types. The insurance market is a natural monopoly. If more than one insurer is active, high risk house owners continue to...

The Effects of Globalization on Worker Training

Gersbach, Hans; Schmutzler, Armin - C.E.P.R. Discussion Papers - 2005

We examine how globalization affects firms’ incentives to provide general worker training. We consider a three-stage game. In stage 1, firms invest in productivity-enhancing training. In stage 2, they can make wage offers for each others’ workers. Finally, Cournot competition takes place....
