Why has no other European country adopted the Research Excellence Framework?

Most European countries have followed the UK's lead in developing performance-based research funding systems (PRFS) for their universities. However, what these countries have not done is adopt the same system, the Research Excellence Framework being its most recent iteration. Instead, many use indicators of institutional performance for funding decisions rather than panel evaluation and peer review. Gunnar Sivertsen has examined systems throughout Europe and finds the REF to be quite unique as a combination of performance-based institutional funding and research evaluation. While most countries do both, they do so in independent setups and with different, less expensive methodologies.
