Which Digital Skills Still Differentiate Work?

This chapter compares digital-skill categories as labour-market signals. The question is not whether basic digital ability matters—it clearly does—but whether a skill is common enough to be a threshold, complex enough to change a role, scarce enough to attract a premium, and connected enough to real work to be valuable. That comparison helps the reader interpret advanced, AI, and GenAI claims without treating every tool name as an equally powerful route to higher pay.

From threshold competence to differentiated capability

A basic digital skill can be economically necessary without being a strong differentiator. If almost every applicant for a role is expected to use email, spreadsheets, standard office software, or routine digital systems, the capability may be part of the entry price. Employers need it, but they may not pay a large additional amount simply because someone has it. The skill enables participation in the work; it does not by itself distinguish one candidate’s expected contribution from another’s.

This is the most important way to read the World Bank’s negative estimate for basic digital skills. In the preferred specification, each additional basic digital skill listed in a vacancy is associated with roughly a 3.9% lower advertised wage. That does not mean basic digital competence makes a worker less valuable. The authors interpret the association as consistent with two patterns: basic skills are widespread, and several basic requirements can signal routine, lower-complexity functions. The coefficient describes the kind of job that lists those requirements, not the personal value of a worker who possesses them.

The distinction matters because a threshold can be invisible when it is present and costly when it is absent. A worker who cannot use a core workplace system may be excluded from a role. Once they can use it, the capability may no longer earn a separate premium because it is already assumed. This is similar to a foundation: necessary for the building, but not necessarily what makes one building more valuable than another.

The OECD’s evidence that ICT use has expanded across low-, medium-, and high-skilled occupations reinforces this point. Digital work is no longer confined to specialist technology roles. As software becomes part of ordinary administration, sales, logistics, education, health, and production, basic fluency spreads through the labour market. Its social and economic importance can rise even as its incremental wage signal falls.

Intermediate and advanced skills occupy a different position. In the World Bank results, each additional intermediate or advanced digital skill is associated with about a 0.8% increase in advertised wages in the preferred specification. In a subsample of digitally enhanced occupations, where digital tools are more closely connected to the core work, the advanced-skill association rises to about 1.7% per skill compared with about 0.6% for intermediate skills.

These estimates are still associations between vacancy requirements and advertised wages.
