Competition and Innovation in a Technology Setting Software Duopoly

Recently the software industry has experienced fundamental changes in market structure through the entry of open source competitors, e.g. Linux's entry into the operating systems market. In a simple model we examine the effects of such a change in market structure from monopoly to duopoly under the assumption that software producers compete in technology rather than price or quantities. The model includes the presence of technological progress and menu costs of adjusting existing software, i.e. innovation. It is found that: (i) moving from monopoly to duopoly does increase the technology level set by firms in the software industry; (ii) a duopoly adjusts more readily to global technological progress than a monopolist. Furthermore, results are presented comparing open source versus for-profit firms in terms of technology levels and innovation.open source software, strategic interaction, duopoly, menu costs

Bug-Fixing and Code-Writing: The Private Provision of Open Source Software

Open source software (OSS) is a public good. A self-interested individual would consider providing such software, if the benefits he gained from having it justified the cost of programming. Nevertheless each agent is tempted to free ride and wait for others to develop the software instead. This problem is modelled as a war of attrition with complete information, job signaling, repeated contribution to the public good and uncertainty in programming. The resulting game does not feature any delay: software will be provided swiftly, by young, low-cost individuals who gain considerably by signaling their programming skills; the startup (and collapse) of an OSS project displays bandwagon dynamics.open source software, war of attrition, public goods

Intrinsic motivation in open source software development

This papers sheds light on the puzzling evidence that even though open source software (OSS) is a public good, it is developed for free by highly qualified, young and motivated individuals, and evolves at a rapid pace. We show that once OSS development is understood as the private provision of a public good, these features emerge quite naturally. We adapt a dynamic private-provision-of-public-goods model to reflect key aspects of the OSS phenomenon. In particular, instead of relying on extrinsic motives for programmers (e.g. signaling) the present model is driven by intrinsic motives of OSS programmers, such as user-programmers, play value or homo ludens payoff, and gift culture benefits. Such intrinsic motives feature extensively in the wider OSS literature and contribute new insights to the economic analysis. --open source software,public goods,homo ludens,war of attrition

Grian Sorghum Performance Tests - 1971

Grain sorghum varieties were evaluated at four locations (Carlisle, Daviess, Hopkins, and Todd Counties) in Kentucky in 1971

Tips for Small Grain Seeding

TEST YOUR SOIL AND SUPPLY THE SUGGESTED LIMING AND FERTILIZER MATERIALS. A soil test is the first step to profitable small grain production. A pH of 6.0 to 6.5 is best, and nitrogen should be applied both in the fall and spring. If your small grains are part of a double cropping system the P and K requirements for both crops should be applied in the fall

Effect of Tillage Tools on Improving Corn Yields from a Compacted Soil

An experiment was conducted on a 2-5% sloping Mercer silt loam soil on a farm in Bourbon/Harrison Counties where very poor corn was grown in 1984 because of soil compaction and drought. Soil test levels of the experimental area were: pH 4.8. and 99, 316, 2070. and 120 lbs/A of P, K, Ca, and Mg, respectively. Examination of the field showed that the compacted zone occurred uniformly in the 0-5 inch surface layer of soil. Cause of this compacted layer was thought to be due to excessive disk tillage in prior years when preparing the field for tobacco production and to winter grazing of a wheat cover crop. The objective of the experiment was to evaluate the influence of fall or spring plowing with a paraplow. chisel plow, or moldboard plow on plowsole bulk density and corn production
