This paper presents an in-depth analysis of patterns and trends in the open-source software (OSS) contributions by the U.S. federal government agencies. OSS is a unique category of computer software notable for its publicly accessible source code and the rights it provides for modification and distribution for any purpose. Prompted by the Federal Source Code Policy (USCIO, 2016), Code.gov was established as a platform to facilitate the sharing of custom-developed software across various federal government agencies. This study leverages data from Code.gov, which catalogs OSS projects developed and shared by government agencies, and enhances this data with detailed development and contributor information from GitHub. By adopting a cost estimation methodology that is consistent with the U.S. national accounting framework for software investment proposed in Korkmaz et al. (2024), this research provides annual estimates of investment in OSS by government agencies for the 2009–2021 period. The findings indicate a significant investment by the federal government in OSS, with the 2021 investment estimated at around $407 million. This study not only sheds light on the government’s role in fostering OSS development but also offers a valuable framework for assessing the scope and value of OSS initiatives within the public sector.

From GitHub to GDP: A framework for measuring open source software innovation
Open source software (OSS) is software that anyone can review, modify, and distribute freely, usually with only minor restrictions such as giving credit to the creator of the work. The use of OSS is growing rapidly, due to its value in increasing firm and economy-wide productivity. Despite its widespread use, there is no standardized methodology for measuring the scope and impact of this fundamental intangible asset. This study presents a framework to measure the value of OSS using data collected from GitHub, the largest platform in the world with over 100 million developers. The data include over 7.6 million repositories where software is developed, stored, and managed. We collect information about contributors and development activity such as code changes and license detail. By adopting a cost estimation model from software engineering, we develop a methodology to generate estimates of investment in OSS that are consistent with the U.S. national accounting methods used for measuring software investment. We generate annual estimates of current and inflation-adjusted investment as well as the net stock of OSS for the 2009–2019 period. Our estimates show that the U.S. investment in 2019 was $37.8 billion with a current-cost net stock of $74.3 billion.

Open source software (OSS) is ubiquitous, serving as specialized applications nurtured by devoted user communities, and as digital infrastructure underlying platforms used by millions of people. OSS is developed, maintained, and extended through the contribution of independent developers as well as people from businesses, universities, government research institutions, and nonprofits. Despite its prevalence, the scope and impact of OSS are not currently well-measured. Recent policies of the U.S. Federal Government promote sharing of software code developed by or for the Federal Government. While the policy to promote reusing and sharing of software created with public funding is relatively new, public funding plays an important and not fully accounted role in the creation of OSS. This paper aims to measure the scope and value of OSS development in the U.S. Federal Government. We collect data from Code.gov, the government’s platform for sharing OSS projects, and study contributions of agencies. The dataset contains 17K repositories from 21 agencies, with the majority of contributions originating from the DOE, NASA and GSA. In addition, we collect data on development activity (e.g., lines of code, contributors) of the repositories on GitHub, the largest hosting facility worldwide. Adopting a cost estimation model from software engineering, we generate estimates of investment in OSS that are consistent with the U.S. national accounting methods used for measuring software investment. Finally, we generate and analyze collaboration network resulting from cross-agency contributions to repositories and explore the centrality of agencies in the network.more » « less

In 2019, Meta purchased CTRLLabs, a neural interface start-up, for more than $500 million. A recent report by Morgan Stanley analysts valued the total addressable market of brain-computer interfaces (BCIs) at around $400 billion in the U.S. alone. Headlines discussing the exploration of novel neural interface technologies by companies such as Blackrock Neurotech, Synchron, and Neuralink have become increasingly common. Although the media often piques our curiosity about this technology, few people truly comprehend its underlying mechanics. Over the past decade, I have dedicated my career to addressing this gap. This article shares experiences and insights obtained from introducing students to physiological computing through the Neuroblock software.more » « less

null (Ed.)Large-scale global reforestation goals have been proposed to help mitigate climate change and provide other ecosystem services. To explore reforestation potential in the United States, we used GIS analyses, surveys of nursery managers and foresters, and literature synthesis to assess the opportunities and challenges associated with meeting proposed reforestation goals. We considered a scenario where 26 million hectares (64 million acres) of natural and agricultural lands are reforested by 2040 with 30 billion trees at an estimated cost of $33 ($24–$53) billion USD. Cost per hectare will vary by region, site conditions, and other factors. This scenario would require increasing the number of tree seedlings produced each year by 1.7 billion, a 2.3-fold increase over current nursery production levels. Additional investment (not included in the reforestation cost estimate) will be needed to expand capacity for seed collection, seedling production, workforce development, and improvements in pre- and post-planting practices. Achieving this scenario will require public support for investing in these activities and incentives for landowners.more » « less

Open source software (OSS), a form of Digital or Knowledge Commons, underlies much of the technology that we use in our daily lives. The existence and continuation of OSS relies on the contribution of private resources – personal time, volunteer energy, and effort of numerous actors (e.g., software developers’ time as a common-pool resource) – to public goods, the benefits of which are enjoyed by everyone. Nonprofit organizations such as the Apache Software Foundation (ASF) attempt to aid this process by providing various collective services to OSS projects, acting as a second-order actor in the production of the public good. To this end, the ASF Incubator has created policies – essentially rules or norms – that serve to protect its interests and, as they say, increase the sustainability of the projects. Each policy requires investment by ASF (in terms of money or the use of volunteer time) or an incubating project (in terms of taking project personnel time), the benefits of which can accrue to either party. Such policies may impose additional costs on incubating projects, leading to a decreased production of the OSS public good. Using the ASF Incubator policy documents, we construct a dataset that records who – ASF or an incubating project – bears the cost and who enjoys the benefit of each policy and procedure. We can code most policy statements as costing one party and benefiting one party. The distribution of costs and benefits according to party indicates whether the second-order actor is contributing to an increase in the public good and if they are doing so sustainably. Through a two-way ANOVA, we characterize the impact of ASF policies on the production of public goods (OSS). Being a part of ASF imposes some costs on projects, but these costs may make projects more sustainable. Our analysis shows that the distribution of costs and benefits is fairly symmetric between the ASF and incubating projects. Thus, the configuration of policies or the “institutional design” of the ASF could aid in producing the OSS public good by providing services that projects require.more » « less
