Bernheim and Rangel 2004<br />

Model of “cue-triggered” addiction. Two selves:<br />

Cognitive self with rational preferences<br />

Visceral brain triggered by random cues in which addictive good is<br />

consumed at any cost.<br />

Probability of trigger increases with past consumption levels.<br />

Ideal policy: only allow rational consumption, eliminate consumption<br />

in hot mode.<br />

Corrective taxation may not be desirable: only distorts consumption in<br />

rational state, not visceral state.<br />

Better solution: regulated dispensation — must place orders one<br />

period in advance<br />
