My dad gave me one dollar bill

‘cause I'm his smartest son,

And I swapped it for two shiny quarters

‘cause two is more than one!

And then I took the quarters

And traded them to Lou

For three dimes – I guess he don't know

That three is more than two!

Just then, along came old blind Bates

And just ‘cause he can't see

He gave me four nickels for my three dimes

And four is more than three!

And I took the nickels to Hiram Coombs

Down at the seed-feed store,

And the fool gave me five pennies for them,

And five is more than four!

And then I went and showed my dad,

And he got red in the cheeks

And closed his eyes and shook his head –

Too proud of me to speak!

Shel Silverstein

Economists generally attribute considerable rationality to the agents in their models. The recent popularity of rational expectations models is more an example of a general tendency than a radical departure. Since rationality is simply assumed, there is little in the literature to suggest what would happen if some agents were not rational.
