Does Buddhism have a model of practical rationality?

A standard model of human practical reasoning is the belief-desire-intention model of action. Very simply put: The agent has a desire (“I want to be a doctor”) and a set of beliefs (“Studying medicine will get me there”) on the basis of which s/he forms an intention to act in a certain way (“I’ll study hard and try to get in to medical school”). When you ask a person, the intention and the desire is what the person refers to as her or his reasons for doing (and not doing) what s/he does. F.ex. staying home and reading instead of going to the pub. Does Buddhism have a model of practical rationality that can be extracted on the basis of canonical texts? And if so, is the Buddhist practical rationality model normative (what's beneficial/not beneficial) or descriptive, based on the agents subjective rationality like the belief-desire-intention model of action? Here is more on the model (as ascribed to D. Davidson, the idea is pretty much all over western philosophy and goes goes back - hold fast! - to Plato).
