At the turn of the millennium, the European Union, worried that it was falling behind the U.S. and Japan in science and innovation, committed to a lofty goal: a European research area (ERA).
The bloc, which grew out of a common market project that ripped down barriers to trade, dreamed of creating what was later dubbed a “single market for science” to complement the E.U.’s prized “four freedoms” of capital, people, services and goods.
It envisaged an E.U. where “people and knowledge can circulate more freely,” the integration of scientists in eastern and western Europe, and for countries to “coordinate” what type of research they funded to avoid policy “overlap.”
For the past two decades, Brussels has tried to push forward this unifying vision -- but frustrated by the pace of change, some universities now think it needs a bigger shove.
The ERA remains an “unfinished project,” said Jan Palmowski, secretary general of the Guild of European Research-Intensive Universities. Though there has been progress, “the original goals haven’t been accomplished.”
With the ERA a priority of the current research and innovation commissioner, Mariya Gabriel, work is under way in Brussels to hammer out a new smorgasbord of targets to hurry it along. One aim on the table is for governments to spend 1.25 percent of gross domestic product on research and development.
But several university associations are exasperated, publicly warning last month that the targets won’t be binding, and they feel left out of the process.
“This is not going to work if you want … free circulation of researchers, students and knowledge between member states,” said Kurt Deketelaere, secretary general of the League of European Research Universities. “It’s an illusion to think that you are going to create a fifth freedom without a legislative framework.”
After all, he said, it took binding measures to realize the E.U.’s cherished economic common market.
Countries still spend vastly different amounts on research, and this is the chief barrier to a full circulation of academics across the bloc, in Palmowski’s view.
In the commission’s most recent report on the ERA, it found that in 2016, Norway’s government spent a full 1 percent of GDP on research, but Poland just 0.16 percent.
Although there are exceptions, the big investors are typically wealthy northern and Scandinavian countries, while the laggards tend to be former Communist states.
This imbalance means a persistent brain drain to already research-strong countries. “As long as you have vastly different spending on research and innovation, you are going to have concentrations of researchers in places that spend more,” Palmowski said.
Another stumbling block is that researchers looking to move around the E.U. are still faced with “27 different schemes of labor, tax and research careers,” said Deketelaere, as the continent is still a patchwork of childcare rights, social security systems and career ladders.
Newly created “European universities” -- consortia of institutions across the continent trying to integrate their research and strategies -- recently reported dozens of headaches resulting from such national barriers.
Still, in some parts of the ERA -- which, although focused on the E.U., is sometimes defined as including neighboring countries such as Switzerland, Britain and Norway -- it’s now “completely unremarkable” for universities to recruit from other European states, raising no more of an eyebrow than a Texan scientist decamping to California, said Palmowski.
In Switzerland, for example, more than a third of Ph.D. students are from E.U. states. Israel, Denmark and Austria are also magnets for mobility.
But other systems remain stubbornly national. In Lithuania, Poland, Greece and Romania, fewer than one in 100 doctoral students come from other E.U. states. Still, there are signs of opening up; since 2007, across the ERA, the proportion of mobile Ph.D. students has been growing by around 4 percent a year, according to the commission.
“The ERA is a mix of real things and rhetorical ones,” said Giulio Marini, an associate at University College London’s Center for Higher Education Studies. Probably more important in allowing researchers to cross borders have been the E.U.’s freedom-of-movement rules -- which Britain has now left -- and frictionless travel across the Schengen Area. The ERA “is not per se a driver of much change,” he judged.
It can boast notable successes: E.U. member states now routinely build scientific infrastructure together, with nearly 20 billion euros ($24 billion) spent across 37 projects over the last two decades. Observers also hail big strides in open science and open access to papers.
And as research and innovation have moved “to the center of the table” for policy makers in Brussels because they are seen as an engine of growth, explained Palmowski, the ERA was seen as ever more crucial.
But 90 percent of research funding still comes from nation-states, cautioned Deketelaere, and there was little sign of national funders pooling their resources to avoid doubling up on projects in different parts of the bloc. “Member states are reluctant to give up power,” he said.
