Final answer:
Transactions that may not be recorded by an electronic accounting system include those with sudden banking changes, the addition of names to bank cards, abrupt will changes, and activities in the underground economy or home production.
Step-by-step explanation:
Transactions that might not be recognized in an electronic accounting system include those pertaining to sudden changes in banking practices, the inclusion of additional names on bank cards, and abrupt changes to wills.
An electronic accounting system might not automatically recognize these changes as they often require verification or manual input due to their unusual nature or potential security implications.
Additionally, if you spend more money than you have in your account, your transaction may be rejected, or your bank may allow the transaction and charge an overdraft fee, which could lead to a costly negative balance.
Transactions associated with the underground economy, such as services paid under the table and illegal sales, are not recorded by electronic accounting systems because they are not officially reported and are difficult to track.
For example, the underground economy in the United States was estimated to be 6.6% of GDP, nearly $2 trillion in 2013. Moreover, certain non-market transactions, like making your own breakfast at home (home production), are not recorded because they do not involve a sale in the marketplace.
