Describe two ways in which financial intermediaries help lower transaction costs in aneconomy.

Financial intermediaries play a crucial role in reducing transaction costs in an economy in two main ways:

1. Economies of Scale: Financial intermediaries, such as banks, can handle large volumes of transactions, which allows them to take advantage of economies of scale. This means that the average cost of each transaction decreases as the number of transactions increases. For example, a bank can process a large number of payments or loans at a lower cost per transaction than if each individual or business had to negotiate and process each transaction separately.

2. Expertise and Specialization: Financial intermediaries have specialized knowledge and expertise in various financial transactions, which individual savers or borrowers may not have. This expertise allows them to reduce the costs associated with researching investment opportunities, assessing credit risk, and monitoring borrowers. For example, a mutual fund manager can use their expertise to select a diversified portfolio of investments, reducing the risk and transaction costs for individual investors who may not have the time or knowledge to do this themselves.
