The Balearic Islands in the 21st century are putting economic theories to the test. While the principles established by theorists generally speak of growth, of going further, in the Islands right now the only thing increasing is the consensus on the need to change course and reduce. Depending on the organization or specialist consulted, the proposals and prescriptions for the future vary between decreasing or maintaining current passenger numbers. But in no case—not even the accommodation sector—is there a proposal to increase arrival statistics. The economic challenge for the Balearic Islands in 2026 has a name: knowing when to slow down and set limits.
