Barter exchanges become extremely difficult in a large economy because of the high costs people would have to incur looking for suitable persons to exchange their surpluses. What does this indicate?

Search costs become prohibitive in a large economy

The correct answer is Option 1: Search costs become prohibitive in a large economy

In a large economy, the complexity and number of transactions increase, making it challenging to find a suitable trading partner who has exactly what one needs and wants what one has. This increases the search costs, which refer to the time, effort, and resources spent finding such a match. As the economy grows, these costs become significantly higher, making barter exchanges less practical and efficient.
