Do students care about the quality of higher education?
For “average” respondents – quality of HEI is of secondary importance Higher expected effort?
Higher drop-out probability?
But not for the best students because: Better diploma appreciated in the job market
Better possibilities to gain in-depth understanding
Makes it possible to get closer to the state-of-the-art
Warning: smartest ≠ top achievers Results = f ( brains, effort, …)

‒ Many 'Nobel' prizes in economics for such issues as:
‒ Asymmetric information
‒ Decisions under risk and uncertainty
‒ Transaction costs
‒ Evolutionary game theory
‒ Contracts
‒ …
