What two factors determine what is offered for sales in a market economy?

In a market economy, the two primary factors that determine what is offered for sale are consumer demand and producer supply. Consumer demand reflects the preferences and purchasing power of buyers, indicating what they want and are willing to pay for. Producer supply represents the willingness and ability of sellers to provide goods and services based on costs, resources, and potential profits. The interaction between these factors shapes the types and quantities of products available in the market.
