Which term refers to all buyers and sellers of a particular good?

The term that refers to all buyers and sellers of a particular good is "market." A market is defined as a place or environment where the exchange of goods and services occurs, bringing together buyers who need products and sellers who provide them.

In economic terms, a market encompasses not just a physical location, but also the broader interactions and relationships among those engaged in the buying and selling process. This can include traditional markets with stalls or shops, as well as digital platforms like e-commerce websites.

An "industry" refers to a specific branch of economic activity that produces goods or services, but it does not imply a direct interaction between buyers and sellers like a market does. A "sector" typically describes a distinct part of the economy, a broader category that can include multiple industries. "Shop" refers to a specific place where goods are sold and does not capture the wider concept of the buyer-seller relationship present in a market. Thus, the correct term that encompasses all parties involved in the trade of a specific good is "market."
