Profit and Loss account and Exploring the origin of DEB 10

• Why did DEB appear in in Italy in the 13th century? Why did DEB appear in Italy in the 13th century? 11

Different perspectives: • DEB as a result of «trial and error» recognising that every transaction had 2 aspects (duality)

or cash Debtor goods Cross-check: cash book and debtor book Why did DEB appear in Italy in the 13th century? 12

Cross-checking in Giovanni Farolfi 1299-1300 records Giovanni Farolfi was a Florentine merchant whose head office in France. The ledger relates exclusively to the branch in Provence.

The Ledger of Giovanni Farolfi & Company is preserved in State Archive in Florence (filed under Carte Strozziane) Why did DEB appear in Italy in the 13th century? 13

• DEB as an evolution of charge and discharge accounting Despite these methods may be perceived as distinct there are examples of hybrid systems

But, DEB goes further in classification of transactions (Galassi, 1996): - Nominal accounts (revenues and expenses) - Personal accounts (debtor/creditors) - Real accounts (other assets and liabilities)

- Evidences about use of DEB from 1211 to 1299 in Italy, but not in the rest of Europe - In UK charge and discharge accounting was predominant Why did DEB appear in in Italy in the 13th century? 14

• Looking for a catalyst justifying the sudden change in 13th century • Hoskin and Macve have grounded the origin of DEB in educational advances occurred in medieval University from the 11th century (Hoskin and Macve, 1986; Macve, 1996) • Edwards (1989) increasing complexity of the Italian business environment, particularly in credit transaction • Contact with the East (Islamic world) (debate between Zaid (2000, 2001) and Nobes (2001)

None single factor can explain the phenomenon satisfactorily References 15
