I think Rand was not much taken with W.S. as he is rarely mentioned in her works.
Shakespeare's father in the incipient capitalism of 16th century England was much involved and likely had his eldest son assist him with the deeds or bonds of deals. These poems are from Shakespeare Undiminished, a work of more than 900 biographical sonnets on the poet.
Shakespeare Undiminished Book 3
Tuition Wrought Him Tough
Tuition wrought him tough, him thrifty, him
Intent to thrive. Censorious trafficking
He’d offer. Verbal scowling, ever grim
In covenants, he’d inflict, unpitying
For money. Tutored to esteem a trade,
He practised estimations to appraise
New wool. In manifold events he made
Decisions, proving sage, judicious days
Enjoying. Traffic should be querulous,
He knew, when by the carping chapmen wool
Was offered. Chaffering vociferous
In sharpest prudence Shakespeare proved, not full
Of pride. He learned repining, loath to pay
Too much, not leave the market in dismay.
Shakespeare Undiminished Book 3
He Chaffer?
He chaffer? he Shakespeare? he sage enough
To shape a deal? A buyer’s readiness
To bicker he revealed, as aptly tough
As traders are in judgement, merciless
Conceits maintaining. His acuity
Came forth in censure, carping at the price
Of wool. “A hundred worthy tods should be
For ninety pounds exchanged,” he said, precise
In cheaping. Gainful bargains he vouchsafed
To buy, the chariest haggler grieving, sure
By instance to succeed. His greed was chafed,
Not lightly cowed, if less expenditure
Pertained. For his renowned negations not
A fool he proved who much for little got.
Shakespeare Undiminished Book 3
Wisely Dubious
Shakespeare, of wisely dubious wit, who trained
His hesitation to demur at length,
In presages suspicious, oft refrained
From trades, aware how prices by the strength
Of new demand might fly. His diffidence
In value never sentiment allowed.
Perfidious markets fearing, providence
He followed, by no reckless instance cowed.
The busiest workings of his brain, in sense
Of proper worth, judicious proved, affairs
Of judgement weighing, in no consequence
Misled, conducted by sagacious cares.
He kept his traffic slow, not lightly bent
On deals but in demurral provident.
