Cicero: Cases on Sales Management and Professional Conduct

Cicero, to calibrate understanding of honest/dishonest business behaviour, offered his son Marcus some examples of dilemmas faced by a basically honest actor who has the chance to gain advantage in a situation. Does the actor remain silent, hold back from taking action or even intervene - when perhaps he/she "should not"?

Case 1: Famine at Rhodes

There is a food-shortage and famine at Rhodes. Corn prices are high. An honest and normally open trader has brought in corn from Alexandria and knows that other traders are only a few days away. Other grain ships are sailing to Rhodes.

Discuss the following issues:

"More grain tomorrow as Prices slump."

Case 2: Selling a house, buying a villa

Selling a house
Imagine an honest man selling a house which appears sound but is badly built and insanitary (poor drains). Nobody knows this except the owner who remains silent. Revealing this would affect the purchasing price. No actual lie is told and nothing is done or said to mislead. In everyday life, sellers have the freedom to deal shrewdly and persuade buyers.

Gaius Canius and the villa
Cicero tells of Gaius Canius, a witty and cultured man. On holiday in Syracuse, Gaius spoke to a banker (Pythius) about buying Pythius' villa as a weekend retreat. Pythius says that the villa is not for sale but invites Gaius for a meal at the villa the next day.

Pythius then asks fishermen (who owe him favours) to fish by the villa the next day . As Pythius entertains Gaius, the fishing-boats add to the picturesque scene. The boatmen bring up part of their catch to show. Gaius asks about the fishing boats. Pythius replies.

"All the fish and all the water in Syracuse are at this very spot; without this place of mine, the men could do nothing. "

Gaius presses Pythius to sell the villa and offers a good price. Pythius finally agrees. Next day Gaius and friends arrived but the boats are gone. A neighbour explains that the previous day was abnormal - nobody ever fished by the villa.

Discuss the following questions:

Further examination

What limiting conditions would you place on the notion of entirely free, competitive market exchange?

  1. Consider both a simple exchange and
  2. an exchange which involves a "special relationship" e.g. where the seller has access to expert or technical information that it would be impossible or practically impossible for the buyer to obtain. This may exist, for example, in a doctor-patient or client-accountant relationship, where higher responsibilities and standards of professional fidelity and disclosure are expected. What are these "standards" and what are the expectations of a "special relationship"?
