I think this is true in many markets. In financial markets it may be less true because of the money at stake but they matter there too.

Still, models with fully rational agents provide a perfectly good approximation for explaining many market outcomes!

while I see the impact of nudging on macro outcomes (e.g. pension fund participation), I am uncertain whether this is due to irrationality.

Tend to agree, but depends on setting & details. Often traditional models can be extended to explain as well. Point is not always to predict

Psychology can be useful but most puzzling phenomena can also be explained by rational models. What you mean by rationality matters.

Still, as forcefully argued by Steve Ross, fully-rational economic models can go a long way to explain many of these market outcomes.
