"If you shift car builders to the DMV, output falls and so does GDP". Don't get your point. GDP includes public added value, estimated by spent wages in the public sector.

En économie, si on est en poste, cet accès existe presque toujours. Elargir encore l'accès? pourquoi pas mais cela n'est pas un accès gratuit, cela coute meme plus cher, meme si le cout est reporté sur les auteurs.

Probably price difference between modes has become so hugh in many situations (consider flight versus train for most international european trips) that all other attributes only rarely compensate for this. How bad this could be for many aspects, this is often where we have to start from.

I would say that they may not be as reliable as wished, but when done properly they can be or are more reliable than other ways of evaluating a project. Nearly each evaluation is a CBA, some are made with method, others are not.

isn't it a bit exagerated ? I understand CBA has limitations and is too often loosely performed. But is the situation so critical that no adequate CBA could teach something (seen some bike lanes CBA in France which were honorable)

Interested by the full cost benefit balance. For comparison : www.sciencedirect.com/science/arti...

"the cost of bus or tram travel was €3 per user per day"
Curious to know if it means something ? e.g. : 300 million euro per year for 100 million travelers/yr means 3 euro per traveller. non "per user per day". To have a cost per user per day, you need to define a "user.day" measure. Weird.

😏 highly discussible. Saw so many qualified engineers making heavy mistakes in CBA. To name one : computing benefits based on the variation of expenditures. Makes no sense.
