Low market integration is a major barrier to European competitiveness in the digital economy. International collaboration of knowledge workers could help to harness market size advantage. Data from the largest coding platform reveals digital collaboration in Europe drops by 16.4 percent at...

Much of today’s software relies on programming code shared openly online. Yet, it is unclear why volunteer developers contribute to open-source software (OSS), a public good. We study OSS contributions of some 22,900 developers worldwide on the largest online code repository platform, GitHub,...

Software engineering is prototypical of knowledge work in the digital economy and exhibits strong geographic concentration, with Silicon Valley as the epitome of a tech cluster. We investigate productivity effects of knowledge worker agglomeration. To overcome existing measurement challenges, we...

Many digital platform host content produced by independent creators and rely on advertising as their primary source of revenues. They commonly use partnership programs to put into place incentives for creators to produce high-quality content by sharing part of the advertising revenue with them....

Software engineering is a field with strong geographic concentration, with Silicon Valley as the epitome of a tech cluster. Yet, most studies on the productivity effects of agglomerations measure innovation with patent data, thus capturing only a fraction of the industry's activity. With data...

Digital tools potentially enable remote collaboration. Analyzing how some 191 thousand software developers in the United States collaborate on the largest online opensource code repository platform, I find 79.8% of users clustering in only ten economic areas. Conditional on economic-area...

Digital work settings potentially facilitate remote collaboration and thereby decrease geographic frictions in knowledge work. Here, I analyze spatial collaboration patterns of some 191 thousand software developers in the United States on the largest code repository platform GitHub. Despite...
